Fleas are perfectly designed by
nature to feast on anything containing blood. Like a shark in the water or a
wolf in the woods, fleas are ideally equipped to do what they do, making them
very difficult to defeat. The bodies of these tiny parasites are extremely
hardy and well-suited for their job.
A flea has a very hard exoskeleton,
which means the body is covered by a tough, tile-like plate called a sclerite.
Because of these plates, fleas are almost impossible to squish. The
exoskeletons of fleas are also waterproof of fleas are also waterproof and shock
resistant, and therefore fleas are highly resistant to the sprays and chemicals
used to kill them.
Little spines are attached to his
plate. The spine the flea scurries through an animal’s fur in – search of
grooming pet tries to pull a flea off through the hair coat, these spines will
extend and stick to the fur like Velcro.
Fleas are some of the best jumpers
in the natural world. A flea can jump seven inches, or 150 times its own
length, either vertically or horizontally. An equivalent jump for a person
would be 555 feet, the height of the Washington Monument. Fleas can jump 30,000
times in a row without stopping, and they are able to accelerate through the
air at an incredibly high rate – a rate which is over ten times what humans can
withstand in an airplane.
Fleas have very long rear legs with
huge thigh muscles and multiple joints. When they get ready to jump. They fold their
long legs up and crouch like a runner on a staring block. Several of their
joints contain a protein called resilin, which helps catapult fleas into the
air as they jump, similar to the way a rubber band provides momentum to a
slingshot. Outward facing claws on the bottom of their legs grip anything they
touch when they land.
The adult female flea mates after
her first blood meal and begins producing eggs in just 1 to 2 days. One flea
can lay up to 50 eggs in one day and over 2,000 in her lifetime. Flea eggs can
be seen with the naked eye, but they are about the size of a grain of salt. Shortly
after being laid, the eggs begin to transform into cocoons. In the cocoon
state, fleas are fully developed adults, and will hatch immediately if
conditions are favorable. Fleas can detect warmth, movement, and carbon dioxide
in exhaled breath, and these three factors stimulate them to emerge as new
adults. If the flea does not detect appropriate conditions, it can remain
dormant in the cocoon state for extended periods. Under ideal conditions, the
entire life cycle may only take 3 weeks, so in no time at all, pets and homes
can become infested.
Because of these characteristics,
fleas are intimidating opponents. The best way to control fleas, therefore, is
to take steps to prevent an infestation from ever occurring.
Based on information in the passage,
the reader can understand that
Each nation has its own peculiar character
which distinguishes it from others. But the people of the world have more
points in which they are all like each other than points in which they are
different. One type of person that is common in every country is the one who
always tried to do as little as he possibly can and to get as much in return as
he can. His opposite, the man who is in the habit of doing more than is
strictly necessary and is ready to accept what is offered in return, is rare
everywhere.
Both these types are usually unconscious of
their character. The man who avoids effort is always talking about his ‘rights’;
he appears to think that society owes him a pleasant easy life. The man who is
always doing more than his sheer talks of ‘duties’ feels that the individual is
in debt to society, and not society to the individual. As a result of their
view, neither of these men thinks that he behaves at all strangely.
The man who talks of ‘duties’:
When we are young, we learn that
tigers and sharks are dangerous animals. We might be scared of them because
they are big and powerful. As we get older, however, we learn that sometimes
the most dangerous animals are also the smallest animals. In fact, the animal
that kills the most people every year is one that you have probably killed
yourself many times: the mosquito.
While it may seem that all
mosquitoes are biters, this is not actually the case. Male mosquitoes eat plant
nectar. One the other hand, female mosquitoes feed on animal blood. They need
this blood to live and produce eggs. When a female mosquito bites a human
being, it transmits a small amount of saliva into the blood. The saliva may or
may not contain a deadly disease. The result of the bite can be as minor as an
itchy bump or as serious as death.
Because a mosquito can bite many
people in the course of its life, it can carry diseases from one person to
another very easily. Two of the most deadly diseases carried by mosquitoes are
malaria and yellow fever. More than 700 million people become sick from these
diseases every year. At least 2 million of these people will die from these
diseases.
Many scientists are working on
safer and better ways to kill mosquitoes, but so far, there is no sure way to
protect everyone in the world from their deadly bites. Mosquito nests can be
placed over beds to protect people against being bitten. These nets help people
stay safe at night, but they do not kill any mosquitoes. Mosquitoes have many
natural enemies like bats, birds, dragonflies, and certain kinds of fish.
Bringing more of these animals into places where mosquitoes live might help to
cut down the amount of mosquitoes in that area. This is a natural solution, but
is does not always work very well. Mosquitoes can also be killed with poisons
or sprays. Even though these sprays kill mosquitoes, they may also harm other
plants or animals.
Although mosquitoes may not seem
as scary as larger, more powerful animals, they are far more dangerous to human
beings. But things are changing. It is highly likely that one day scientists
will find a way to keep everyone safe from mosquitoes and the diseases they
carry.
According to the author, some
people are more afraid of tigers and sharks than mosquitos because tigers and
sharks
Right now, I am looking at a shelf
full or relics, a collection of has-beens, old-timers, antiques, fossils. Right
now I am lolling at a shelf full of books. Yes that’s right. If you have some
spare cash (the doing rate is about $89) and are looking to enhance your reading
experience, then I highly suggest you consider purchasing an e-reader.
E-readers are replacing the books of old, and I welcome them with open arms (as
you should).
If you haven’t heard of an e-reader
and don’t know what it is, then please permit the following explanation. An
e-reader is a device that allows you to read e-books. An e-book is a
book-length publication in digital form, consisting of text, images, or both,
and produced on, published through, and readable on computers or other
electronic devices. Sometimes the equivalent of a conventional printed book,
e-books can also be born digital. The Oxford Dictionary or English defines the
e-book as “an electronic version of a printed book, “but e-book can and do
exist without any printed equivalent.
So now you know what an e-reader is.
But you still may be wondering why they put printed books to shame. E-readers
are superior to printed books because they save space, are environmentally friendly,
and provide helpful reading tips and tools that printed books do not.
E-readers are superior to printed
books because they save space. The average e-reader can store thousands of
digital book, providing a veritable library at your fingertips. What is more,
being the size and weight of a thin hardback, the e-reader itself is relatively
petite. It is easy to hold and can fit in a pocketbook or briefcase easily. This
makes handling ponderous behemoths such as War and Peace, Anna Karenina, and
Les Miserables a breeze. Perhaps the only drawback to the space-saving aspect
of an e-reader is that it requires you to find new things to put on your
shelves.
In addition, e-readers are superior
to books because they are environmentally friendly. The average novel is about
300 pages long. So, if a novel is printed 1000 times, it will use 300,000
pieces of paper. That’s a lot of paper! If there are about 80,000 pieces of
paper in a tree, this means it takes almost 4 trees to make these 1000 books.
Now, we know that the average bestseller sells about 20,000 copies per week.
That means that it takes over 300 trees each month to sustain this rate. And
for the super bestsellers, these figures increase dramatically. For example,
the Harry Potter book series has sold over 450 million copies. That’s about 2
million trees! Upon viewing these figures, it is not hard to grasp the severe
impact of printed books on the environment. Since e-reader use no trees, they
represent a significant amount of preservation in terms of the environment and
its resources.
Finally, e-reader are superior to
books because they provide helpful reading tips and tolls that printed books do
not. The typical e-reader allows its user to customize letter size, font, and
line spacing. It also allows highlighting and electronic bookmarking.
Furthermore, it grants users the ability to get an overview of a book and then
jump to a specific electronic bookmarking. Furthermore, it grants users the
ability to get an overview of a book and then jump to a specific location based
on that overview. While these are all nice features, perhaps the most helpful
of all is the ability to get dictionary definitions at the touch of a finger.
On even the most basic e-reader, users can conjure instant definitions without
having to hunt through a physical dictionary.
It can be seen that e-readers are
superior to printed books. They save space, are environmentally friendly, and
provide helpful reading tips and tools that printed books do not. So what good
are printed books? Well, they certainly make nice decorations.
As used in paragraph 3, which of the
following describes something that has been “put to shame”?
The history of the modern world is a
record of highly varied activity, of incessant change, and of astonishing
achievement. The lives of men have, during the last few centuries, increasingly
diversified, their powers have greatly multiplied, their powers have greatly
multiplied, their horizon been enormously enlarged. New interests have arisen
in rich profusion to absorb attention and to provoke exertion. New aspirations
and new emotions have come to move the soul of men. Amid all the bewildering phenomena,
interest, in particular, has stood out in clear and growing pre-eminence, has expressed
itself in a multitude of ways and with an emphasis more and more pronounced,
namely, the determination of the race to gain a larger measure of freedom than
it has ever known before, freedom in the life of the intellect and spirit,
freedom in the realm of government and law, freedom in the sphere of economic
and social relationship. A passion that has prevailed so widely, that has transformed
the world so greatly, and is still transforming it, is one that surely merits
study and abundantly rewards it, its operations constitute the very pith and
marrow of modem history.
Not that this passion was unknown to
the long ages that proceeded the modern periods. The ancient Hebrews, the
ancient Greeks and Roman blazed the was leaving behind them a precious heritage
of accomplishments and suggestions and the men who were responsible for the
Renaissance of the fifteenth century and the Reformation of the sixteen century
contributed their imperishable part to this slow and difficult emancipation of
the human race. But it is in modern times the pace and vigour, the scope and
sweep of this liberal movement have so increased unquestionably as to dominate
the age, particularly the last three centuries that have registered great
triumphs of spirit.
What according to the author, is the
history of the modern world a record of?
The public distribution system, which provides food at low
prices, is a subject of vital concern. There is a growing realization that
thought Pakistan has enough food to feed its masses three square meals a day,
the monster of starvation and food insecurity continues to haunt the poor in
our country.
Increasing the purchasing power of the poor through
providing productive employment leading to rising income, and thus good standard
of living is the ultimate objective of public policy. However, till then, there
is a need to provide assured supply of food through a restructured more
efficient and decentralized public distribution system (PDS).
Although the PDS is extensive – it is one of the largest
such systems in the world – it has yet to reach the rural poor and the far off
places. It remains an urban phenomenon, with the majority of the rural poor
still out of its reach due to lack of economic and physical access. The poorest
in the cities and the migrants are left out, for they generally do not possess
ration cards. The allocation of PDS supplies in big cities is larger than in
rural areas. In view of such deficiencies in the system, the PDS urgently needs
to be streamlined. In addition, considering the large food grains production
combined with food subsidy on one hand and the continuing slow starvation and dismal
poverty of the rural population on the other, there is a strong case for making
PDS target group oriented.
The growing salaried class is provided job security, regular
income, and percent insulation against inflation. These gains of development
have not percolated down to the vast majority of our working population. If one
compares only dearness allowance to the employees in public and private sector
and looks at its growth in the past few years, the rising food subsidy is
insignificant to the point of inequity. The food subsidy is a kind of D.A. to
the poor, the self-employed and those in the unorganized sector of the economy.
However, what is most unfortunate is that out of the large budget of the so –
called food subsidy, the major part of it is administrative cost and wastages.
A small portion of the above budget goes to the real consumer and an even
lesser portion to the poor who are in real need.
It is true that subsidies should not become a permanent feature
except for the destitute, disabled widows and the old. It is also true that
subsidies often create a psychology of dependence and hence is habit – forming,
killing the general initiative of the people. By making PDS target group
oriented, not only the poorest and neediest would be reached without additional
cost, but it will actually cut overall costs incurred on large cities and for
better off localities. When the food and food subsidy are limited the rural and
urban poor should have the priority in the PDS supplies. The PDS should be
closely linked with programs of employment generation and nutrition
improvement.
Food subsidy leads to

At the time Jane Austen’s novels
were published – between 1811 and 1818 – English literature was not part of any
academic curriculum. In addition, fiction was under strenuous attack. Certain
religious and political groups felt novels had the power to make so-called
immoral characters so interesting that young readers would identify with them;
these groups also considered novels to be of little practical use. Even
Coleridge, certainly no literary reactionary, spoke for many when the asserted
that “novel-reading occasions the destruction of the mind’s powers.”
These attitudes towards novels help
explain why Austen received little attention from early nineteenth-century
literary cities. (In any case a novelist published anonymously, as Austen was,
would not be likely to receive much critical attention.) The literary response
that was accorded to her, however, was often as incisive as twentieth-century
criticism. In his attack in 1816 on novelistic portrayals “outside of ordinary experience,”
for example. Scott made an insightful remark about the merits of Austen’s
fiction.
Her novels, wrote Scott, “present to
the reader an accurate and exact picture of ordinary everyday people and
places, reminiscent of seventeenth-century Flemish painting.” Scott did not use
the word ‘realism’, but he undoubtedly used a standard of realistic probability
in judging novels. The critic Whately did not use the word ‘realism’, either,
but he expressed agreement with Scott’s evaluation, and went on to suggest the possibilities
for moral instruction in what we have called Austen’s ‘realistic method’ her
characters, wrote Whately, are persuasive agents for moral truth since they are
ordinary persons “so clearly evoked that we feel an interest in their fate as
if it were our own.” Moral instruction, explained Whately, is more likely to be
effective when conveyed through recongnizably human and interesting characters
than when imparted by a sermonizing narrator. Whitely especially praised Austen’s
ability to create character who “mingle goodness and villainy, weakness and
virtue, as in life they are always mingled. “Whitely concluded his remarks by
comparing Austen’s art of characterization to Dickens’, starting his preference
for Austen’s.
Yet, the response of
nineteenth-century literary critics to Austen was not always so laudatory, and
often anticipated the reservations of twentieth-century literary critics. An
example of such a response was Lewes complaint in 1859 that Austen’s range of
subject and characters was too narrow. Praising her verisimilitude, Lewes added
that, nonetheless her focus was too often only upon the unlofty and the
commonplace. (Twentieth-century Marxists, on the other hand, were to complain
about what they saw as her exclusive emphasis on a lofty upper middle class.)
In any case having being rescued by literary critics from neglect and indeed
gradually lionized by them, Austen steadily reached, by the mid-nineteenth
century, the enviable pinnacle of being considered controversial.

Lilly loves her town. She loves
the mall. She loves the parks. She also loves her school. Most of all, though,
Lilly loves the seasons. In her old town, it was hot all of the time.
Sometimes it is cold in Lilly’s
new town. The cold season is in winter. Once in a while it snows. Lilly has
never seen snow before. So far her, the snow is exciting as well as very
beautiful. Lilly has to wear gloves to keep her hands warm. She also wear a
scarf around her neck.
In spring, flowers bloom and the
trees turn green with new leaves. Pollen falls on the cars and windowsills and
makes Lilly sneeze. People work in their yards and mow their grass.
In summer, Lilly wears her old
shorts and sandals- the same ones she used to wear in her old town. It is hot
outside, and dogs lie in the shade. Lilly and her friends go to a pool or play
in the water sprinkler. Her father cooks hamburgers on the grill for dinner.
Lilly’s favorite season is autumn.
In autumn, the leaves on the trees turn yellow, gold, red, and orange.
Halloween comes in autumn, and this Lilly’s favorite holiday. Every Halloween,
Lilly wears a costume. Last year she wore a mouse costume. This year she will
wear a fish costume.
One evening in autumn, Lilly and
her mom are on sitting together on the porch. Mom tells Lilly that autumn is
also called “fall”. This is a good idea, Lilly thinks, because in the fall all
of the leaves fall down from the trees.
