Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.

If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seed. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores (胚芽). Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.

1.The main idea of the first paragraph is that ______.

A. plants are important for life

B. plants cannot grow without air

C. there are many plants in the world

D. we can’t live without water

2.Plants can make food from _______.

A. flower, water and air B. water, sunlight and air

C. air, water and soil D. air, sun and light

3.What can we infer from the passage?

A. Of all living things animals are most important.

B. Spores are seeds.

C. All fruits of flowering plants have seeds.

D. Without plants, man will die out.

4.This passage may be taken from ______.

A. a medicine book B. a novel

C. a science magazine D. an experiment report

How to be more friendly and social

If you tend to be shy, it can feel uncomfortable to put yourself out there socially. 36 You can make the extra effort to be more friendly and open to others, while still keeping your own personality.

37 The key to connecting to other people is showing interest in them. When you’re truly interested in someone else’s thoughts, feelings, experiences, stories, and opinions, they’ ll like you for it. You’ll make far more friends by showing your interest rather than trying to get people interested in you.

Be genuine (真诚的). 38 If you’re just pretending to listen or care, others will pick up on it.

Rather than promoting greater connection, your efforts will likely have the opposite effect. No one likes to be manipulated (摆布). If you’re not actually interested in the other person, then stop trying to connect.

Pay attention. 39 By paying close attention to what they say and how they interact, you’ll quickly get to know them. 40 Don’t ignore the details, such as remembering someone’s preferences, the stories they’ve told you, and what’s going on in their life.

A. Faking (伪装) takes talent.

B. Focus on others, not yourself.

C. Little things go a long way.

D. Getting to know them is the key.

E. Make an effort to truly listen to the other person.

F. Showing interest in others can’t be faked.

G. But you don’t have to be naturally outgoing or the life of the party to make new friends.

An article published recently in the scientific journal Nature is shedding new light on an important, but so far little has been appreciated, aspect of human evolution. In this article, Professors Dennis Bramble, and Daniel Lieberman suggest that the ability to run was a decisive factor in the development of our species. According to the two scientists, humans possess a number of anatomical(人体结构的)features that make them surprisingly good runners. “We are very confident that strong selection for running,which came at the expense of the historical ability to live in trees-was helpful in the origin of the modern human body form,” says Bramble, a biology professor at the University of Utah.

Traditional thinking up to now has been that the upright body form of modern humans has come about as a result of the ability to walk, and that running is simply a by-product of walking. Furthermore, humans have usually been regarded as poor runners compared to such animals as dogs, horses or antelopes. However, this is only true if we consider fast running over short distances. Even Olympic athlete can hardly run as fast as a horse can gallop, and can only keep up a top speed for fifteen seconds or so. Horses and antelopes, on the other hand, can run at top speed for several minutes, clearly outperforming us in this respect. But when it comes to long-distance running, humans do astonishingly well. They can maintain a steady pace for miles, and their overall speed compares favorably with that of horses or dogs.

Bramble and Lieberman examined twenty-six anatomical features found in humans. One of the most interesting of these is the nuchal ligament(颈背的韧带). When we run, it is this ligament that prevents our head from pitching back and forth or from side to side. Therefore, we are able to run with steady heads held high. The nuchal ligament is not found in any other surviving primates(灵长类动物), although the fossil(化石)record shows that Homo erectus, an early human species that walked upright, much as we do, also had one. Then there are our Achilles tendons(跟腱)at the backs of our legs, which have nothing to do with walking. When we run, these tendons behave like springs, helping to push us forward. Furthermore, we have low, wide shoulders, virtually disconnected from our skulls (the bony part of the head), another anatomical adaptation which allows us to run more efficiently.

But what evolutionary advantage is gained from being good long-distance runners? One assumption is that this ability may have permitted early humans to obtain food more effectively. “What these features and fossil facts appear to be telling us is that running evolved in order for our direct ancestors to compete with other carnivores (animals that eat meat) for access to the protein needed to grow the big brains that we enjoy today.” says Lieberman.

1.We can learn from the passage that the human ability to run _______.

A. was only recently described in a scientific journal

B. played an important part in human evolution

C. was considered more natural than the ability to live in trees

D. contributed to the form of human language

2.According to the second paragraph, humans _______

A. are better runners than most other animals

B. are not good at running short distances

C. compare unfavorably with horses and dogs

D. are poor long-distance runners

3.It appears that the nuchal ligament _______.

A. enables us to run with steady heads

B. is found in modern primates only

C. prevents the head from being held high

D. is a unique feature of carnivores

4.The passage does NOT tell us that _______

A. early humans had an advantage in obtaining food thanks to the running ability

B. fossils help us better understand human evolution.

C. our Achilles tendons are an adaptation for running efficiently

D. big brains may have been evolved for running long-distance

It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible. Everybody knows that the nicest men would become fierce tigers behind the wheel. It is all right to have a tiger in a cage, but to have one in the driver’s seat is another matter.

Road politeness is not only good manners, but a good sense. It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving. On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and becomes so necessary in modern traffic conditions. But such behavior of politeness is by no means enough. Many drivers nowadaysdon’t even seem able to recognize politeness when they see it.

However, misplaced politeness can also be dangerous. A typical example is the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may not be able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to.

An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in a traffic stream without causing total blockages that give rise to unpleasant feelings. Unfortunately, modern drivers can’t even learn to drive, let alone master the roadmanship (公路驾车技能). Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users. It is high time for all of us to take this message to heart.

1.The most suitable title for this passage would be __________.

A. Traffic Jams B. Good Manners

C. Road Politeness D. Modern Drivers

2.Troubles on the road are often caused by __________.

A. traffic jams

B. the behavior of the drivers

C. the great speed of modern life

D. terrible road conditions

3.According to the writer, a good driver should __________.

A. encourage children to cross the road whenever they want to

B. beat back when forced to face rude driving

C. be able to recognize politeness when he sees it

D. join in a traffic stream quickly however other people feel

4.It is not always right for drivers to __________.

A. master the roadmanship

B. neglect politeness when they see it

C. give a friendly nod in answer to an act of politeness

D. encourage old ladies to cross the road whenever and wherever they want to

There was once an 11-year-old boy who went fishing every time he went to an island in the middle of a New Hampshire lake.

On the day before bass (巴斯鱼) season opened, he and his father were fishing early in the evening, catching other fish with worms. Then he tied on a small silver lure(鱼饵) and put it into the lake. Suddenly the boy felt something very big pulling on the lure. His father watched with admiration as the boy skillfully brought the fish beside the bank. Finally he lifted the tired fish from the water. It was the largest one he had ever seen, but it was a bass.

The boy and his father looked at the big fish. The father lit a match and looked at his watch. It was 10 pm — two hours before the season opened. He looked at the fish, then at the boy. “You’ll have to put it back, son,” he said.

“Dad!” cried the boy. “There will be other fish,” said his father. “Not as big as this one,” cried the boy. He looked around the lake. No other fishermen or boats could be seen in the moonlight. He looked again at his father.

Even though no one had seen them, nor could anyone ever know what time he had caught the fish, the boy could tell from his father’s voice that the decision couldn’t be changed. He threw the huge bass into the black water.

The big fish disappeared. The boy thought that he would never again see such a big fish.

That was 34 years ago. Today the boy is a successful architect in New York City. He often takes his own son and daughters to fish at the same place.

And he was right. He has never again caught such a large fish as the one he got that night long ago. But he does see that same fish ... again and again ... every time he has an ethical (道德的) decision to make. For, as his father had taught him, ethics are simple matters of right and wrong. It is only the practice of ethics that is difficult.

1.How did the father feel when he saw his son skillfully pulling a big fish out of the water?

A. Proud. B. Nervous.

C. Curious. D. Shocked.

2.From the text we know that ______.

A. the father didn’t love his son

B. the father always disagreed with his son

C. the father disliked the huge fish

D. the father was firm and stubborn

3.The successful architect went fishing with his children at the same place because ______.

A. they might catch a big fish there

B. he remembered the moral lesson from his father

C. he wanted to remember his father

D. their children enjoyed fishing there

4.What does the author want to show in the story?

A. It is easy to say something, but difficult to do.

B. An ethical decision is not difficult to make.

C. It is hard to tell right from wrong sometimes.

D. Fishing helps you to make right ethical decisions.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

With all the wars, fighting and sadness in the world today, it's not only necessary, but also essential to have a good sense of humor just to help us get through each and every day of our lives. Putting a smile on someone's face when you know they are feeling down in the dumps (处于沮丧中), as the saying goes, makes me feel good and warms my heart.

How would you feel if you could not joke around with your wife, husband, child, co-worker neighbor, close friend, or even just someone that you are standing in line with at your comer store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is common courtesy (礼貌) to speak to others that are around you.

I know of a few people that don’t have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their face. They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?

Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to bypass the sadness and bring a little light into our lives. So, I believe our best medicine is to get together and tell some jokes and have some fun laughing together.

1.The author answers the question in the second paragraph with ________.

A. facts and descriptions B. examples and conclusion

C. evidence and argument D. stories and persuasion

2.In writing the passage, the author mainly intends to ________.

A. encourage people to be humorous in daily life

B. talk about his own understanding of humor

C. introduce a practical way to get through daily life

D. convince people of the power of being optimistic about life

3.What is the author' s attitude towards the present world?

A. Positive. B. Indifferent.

C. Satisfied. D. Critical.
