Butterflies(蝴蝶) are some of the most fascinating (迷人的) and beautiful insects in the world. Adult butterflies will live about two to four weeks. They use their senses of sight, touch, hearing, smell and taste to survive in the world, find food and mates, lay eggs in a proper place, migrate (迁移) and avoid hungry enemies.
Butterflies have large compound eyes (复眼), which allow them to see in all directions without turning their heads. Like most insects, butterflies are very near-sighted, so they are more attracted to many flowers. Butterflies do not “see” colors such as red, green and yellow, but they can sense sunlight, which shows the direction in which the sun is shining, as well as ultraviolet light (紫外线), which is present on many flowers and guides butterflies to find honey sources.
Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don’t have one. Sense receptors (感受器) are in their antennae (触角), feet and many other parts of the body. They can help butterflies find their favorite flower honey, food and mates.
Butterflies’ feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find proper places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Butterflies don’t have ears. Instead they “hear” sounds through their wings by sensing changes in sound vibrations (振动).
Butterflies may possess senses we haven’t known about till today, because their body structure (结构) is very different and difficult to understand, when observed through our own human senses. （325 words）What can we learn from the second paragraph?

How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.
What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner, however, uses a group of X rays to give a cross-sectional（横截面）view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.
CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.What is NOT true of a CAT scan?
| A．It is safer than regular X rays. |
| B．It makes use of computer techniques. |
| C．It can stop the action of an organ for a short time. |
| D．It gives clear pictures of active, moving body parts. |
The underlined words “a foreign object”（Para 3）most probably refer to.
| A．a badly injured part inside the body |
| B．a new thing that is unknown to the doctor |
| C．a strange organ that has grown in the body |
| D．an object that gets inside the body by chance |
What is the special use of the latest CAT scanners?
| A．It provides clear photos of moving organs. |
| B．It can take 3-dimension（三维）pictures of inside organs. |
| C．It won’t cause serious skin burns, cancer or other damage to the body. |
| D．It helps to find out what is going on inside a person’s body without opening it up. |
We can infer from this passage that.
| A．patients in front of CAT may suffer from a bit of radiation |
| B．doctors need no opening-up of the body with CAT scanners |
| C．CAT scanners are more expensive than regular X-ray machines |
| D．CAT scanners can take photos of either the whole body or a part of it |

Most people hate change, which is sad since we often go through intense changes in life. And for some of us, even the smallest changes can upset our day. So the question is: Why do most of us find making adjustments to our lives so hard?
Fear of change is nothing new. Over a century ago, the Parisians were unhappy over a particular addition to their city: the Eiffel Tower. In fact, the citizens were so angry about the plans for the tower that they protested its construction. As strange as it may seem, their anger was completely natural. They were given no choice about the huge change that was going to be made, so they became angry.
But we get upset over changes even when we do have a say in the matter and think about them carefully. Changes are brought about every day by the decisions we make: which school to attend, which job to take, whom to marry. Voluntary changes also make most of us uneasy because we don’t know how those changes will affect our future.
People have discovered that the key to overcoming the fear and anger associated with change is to be flexible. When they are flexible, people can adapt to new situations more easily. Being flexible is especially important in the 21st century as technology makes change occur faster than ever before. Those who oppose change, especially with technology in the workplace, may find themselves out of a job.
When change comes, and you have no choice but to face it, embrace it. A positive attitude helps a lot. In fact, the change may turn out to be the best thing for you. That new job you got may end up being much better than your old one. You may make the best friends of your life in the new city you moved to. Don’t merely focus on how you feel about change; instead decide to accept the change. The change is the reality, and it’s up to you whether the change will be a success or a failure. You never know – your next change may be your life’s Eiffel Tower!Why did the building of the Eiffel Tower make the Parisians unhappy?
| A．Because they didn’t like the design of the Eiffel Tower. |
| B．Because they couldn’t avoid accepting the Eiffel Tower. |
| C．Because it was no use building the Eiffel Tower. |
| D．Because the Eiffel Tower seemed strange. |
According to the passage, it can be inferred that what won’t disturb us are _____________.
| A．the changes that have agreement with one’s will |
| B．the small changes we meet in our daily life |
| C．the changes whose effect we can predict and control |
| D．the changes that we discuss or consider thoroughly |
How should we overcome negative emotions that the changes bring?
| A．We are not supposed to face the changes and let them alone. |
| B．We should actively accustom ourselves to the new circumstance. |
| C．We should not take the changes seriously and avoid them as much as possible. |
| D．We should know that the changes merely bring us bad influence. |
What does the underlined sentence in the last paragraph mean?
A．The change will probably make you fail like the Eiffel Tower. |
| B．The change is like the Eiffel Tower which is not good for our future life. |
| C．Your future life is never known just like the Eiffel Tower unknown to the Parisians. |
| D．Your future life is likely to be a great achievement due to the change. |
What is the best title for the passage?
| A．The Psychology of Change | B．The ways to Overcome the Fear |
| C．Changes That Disturb Us | D．The Bad Effect of Changes |
The common cold is the world’s most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread fallacy(谬误) of all is that colds caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.
In the Second World War prisoners at the notorious Auschwitz concentration camp(集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter？Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms(症状). The writer offered _______ examples to support his argument.
| A．4 | B．5 | C．6 | D．3 |
Which of the following does not agree with the chosen passage?

| D．A person may catch a cold by touching someone who already has one. |
Arctic explorers may catch colds when _______.
| A．they are working in the isolated arctic regions |
| B．they are writing reports in terribly cold weather |
| C．they are free from work in the isolated arctic regions |
| D．they are coming into touch again with the outside world |
Volunteers taking part in the experiments in the Common Cold Research Unit ______.
| A．suffered a lot | B．never caught colds |
| C．often caught colds | D．became very strong |
The passage mainly discusses _______.
| A．the experiments on the common cold |

What if you could fly like a bird just by thinking happy thoughts? Or you could disappear to a faraway land, never grow old and fight pirates every day? For Peter Pan and his friends, the Lost Boys, these dreams come true.
More than 100 years after this playful boy was “born”, Peter Pan and his friends are to continue their adventure in a sequel(续集)to J.M. Barrie’s original novel. “Peter Pan in Scarlet”(重返梦幻岛),written by British author Geraldine McCaughrean, was published earlier this month.
The sequel brings all the original characters back. Peter Pan’s friends, the Lost Boys, are now grown up and live in the real world. What’s more, at the end of the first book, Peter Pan thinks he has killed his enemy, Captain Hook. But ,new readers discover he is not so dead at all.
For those who are unfamiliar with the original story, Peter Pan lives in faraway Neverland with a group of orphans. But they are eager for a real mother and Peter Pan flies to London with a fairy(仙女), Tinkerbell, to find one. They visit a young girl, Wendy, who loves to read stories, and bring her and her two brothers back to Neverland to live with them. In Neverland, children never have to grow up, and there are no parents to tell them what to do.
Many teenagers dream of a world where they don’t have to grow old and take responsibility. But, the author explains such a world is not the paradise(乐园)when it first appears: adventures can be scary and often dangerous, and, though we all sometimes dream of running away, we all need someone to love and look after us too.The passage is written to ________.

When Harvard was founded in 1636, there were no other colleges in the American colonies, and it would become the model for many of those that followed. When it began requiring applicants to take a test known as the SAT in 1935, Harvard started another trend. Two years ago, after it announced an aggressive new financial-aid policy, it helped push social class to the center of the national debate over higher education and forced two of its main competitors, Stanford and Yale, to follow its lead.
Last week. Harvard began to make another effort to affect higher education in its image, its president, Derek Bok, announced that the college would abandon its early admissions program, which for decades has allowed high school seniors to apply in October and get an answer yes, no or maybe – in December, shortly before the regular deadline for applications.
Harvard officials argue that the program is beneficial to rich students who don't need to compare financial-aid offers from various colleges. After the announcement, many people within education urged other colleges to take a similar step.
"We're thrilled," said Laurie Kobick, a college counselor (顾问) at Thomas Jefferson High School for Science and Technology in Alexandria, Va. "I think it's going to make admissions better in so many different ways. It will indeed go a small way toward leveling the field among applicants. Of course, it will also have an effect on colleges, and the biggest winner will almost certainly be Harvard. a fact that may prevent many other colleges – perhaps all of them – from following Hazard this time. Because any college that does so will risk losing some of its best applicants."From the first paragraph we can learn that Harvard ____.
| A．was the first college in the American colonies |
| B．was best known for the SAT |
| C．was muck better than Stanford and Yale |
| D．refused to offer financial-aid to applicants |
By abandoning early admissions program, Harvard wants ____.
| A．to attract the public's attention |
| B．to influence higher education in its own way |
| C．to save money spent in attracting students |
| D．to allow its competitors to admit more students |
Early admissions program is good for rich students because ____.
| A．they have more chances to enter college |
| B．they can enter college with a lower score |
| C．they have special right to be admitted into college |
| D．they have no problem in supporting their studies |
Why does Laurie Kobick think other colleges may not follow Harvard?
| A．Because they think the action will harm high education. |
| B．Because they are afraid that the action is not practical. |
| C．Because they may attract fewer top students than he[ore, |
| D．Because they are afraid the action will damage their reputation. |
