题目内容

There are only about 1,000 Hawaiian monk seals(夏威夷僧海豹) left and its population is going down 4% a year. Hawaiian monk seals are found in the northwest part of the Hawaiian Islands. They spend a lot of time at sea. They are able to dive 600 feet deep, and can stay under water for up to 20 minutes. Adults grow up to seven feet long, and weigh between 400 and 600 pounds. They can live as long as 30 years.

These seals are born on land. Every year, usually in May or June, females find sandy beaches and give birth to a single baby. The female seals avoid beaches where the water becomes deep very quickly because this lets sharks swim close to land and catch the seals.

Mothers stay with their babies for six weeks. During that entire time, they do not leave the beach even to eat. Instead, they live off fat that they have stored up over the previous year and feed their babies with fat-rich milk. After six weeks, mothers go back to the sea. The young have to live on their own.

Human disturbance(打扰) has been regarded as the important factor in the decrease of the monk seals. In fact, if human come too near a mother seal too often, she will go out to the sea. Unfortunately, this usually means death for the baby. It is now against the law for people to come within 100 yards of a seal on a beach.

Recent research has shown that the decrease in the Hawaiian monk seal population is due to lack of survival of these seals at one of the most important breeding(繁殖) beaches at French Frigate Shoals. Also, seals often get trapped in fishermen and by changes in weather patterns. If these threats(威胁) were not enough, during the breeding season, males will attack females until they are badly injured or finally killed.

1.What can we learn about Hawaiian monk seals?

A．They are in danger of dying out.

B．They spend most of the time on the beach.

C．They are the largest animals on the Hawaiian Islands.

D．They can stay under water as long as they like.

2.According to the text, a seal baby______.

A．is born at sea

B．is fed on fat by the mother

C．stays with its parents all life

D．is looked after by its mother for 6 weeks

3.It can be inferred from the text that______.

A．sharks are a threat to Hawaiian monk seals

B．male monk seals fight each other for females in the breeding season

C．when disturbed by people, the mother seal will protect the baby seal

D．Hawaiian monk seals give birth usually in July

4.What are the last two paragraphs mainly about?

I fell in love with England because it was quaint （古雅）—all those little houses, looking terri??bly old-fashioned but nice, like dolls’ houses．I loved the countryside and the pubs, and I loved London．I’ve slightly changed my mind after seventeen years because I think it’s an ugly town now．

Things have changed. For everybody, England meant gentlemen, fair play, and good man??ners．The fair play is going, unfortunately, and so are the gentlemanly attitudes and good man??ners—people shut doors heavily in your face and politeness is disappearing．

I regret that there are so few comfortable meeting places．You’re forced to live indoors．In Paris I go out much more, to restaurants and nightclubs．To meet friends here it usually has to be in a pub, and it can be difficult to go there alone as a woman．The cafes are not terribly nice．

As a woman, I feel unsafe here．I spend a bomb on taxis because I will not take public trans??port after 10 p．m．I used to use it, but now I’m afraid．

The idea of family seems to be more or less non-existent in England. My family is well united and that’s typically French．In Middlesex I had a neighbour who is 82 now．His family only lived two miles away, but I took him to France for Christmas once because he was always alone．

The writer doesn’t like London because she ______．

A．is not used to the life there now

B．has lived there for seventeen years

C．prefers to live in an old-fashioned house

D．has to be polite to everyone she meets there

Where do people usually meet their friends in England?

A．In a cafe． B．In a restaurant． C．In a nightclub. D．In a pub．

The underlined part “it” （in Par A．4） refers to______．

A．a taxi B．the money C．a bomb D．public transport

The writer took her neighbour to France for Christmas because he ______．

A．felt lonely in England B．had never been to France

C．was from a typical French family D．didn't like the British idea of family

This is a dangerous world we live in. The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, ect. You know this because you’ve heard all the statistics on the news and in the paper. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little.

This growing trend of reporting only part of the information is becoming dangerous. For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors, is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statement is true, yet this chemical is necessary to all life on earth. The students made a mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.

The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave our information that is different from his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people die each year when skiing, while 897 die from lightening strikes, but which is really more dangerous? If you think more about it, you will realize far fewer people go skiing each year than the number of people in danger of a lightning strike. When you think about it again, skiing is more dangerous than you might at first think when looking at the statistics. If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s. To be warned is just to be prepared.

What’s the author’s attitude towards the growing trend of reporting only part of the

information?

Disapproving B. Positive C. Indifferent D. Dangerous

In the first paragraph, what does the writer suggest?

A. We are now living in a dangerous world.

B. We get a lot of false statistics from the media.

C. There are around us more and more murders diseases, ect.

D. Statistics alone without full background don’t give us an accurate picture of things.

What’s the purpose of the writer’s using the two examples in the second paragraph?

A. To argue that high school students are easily persuaded.

B. To prove what is necessary to us might be dangerous.

C. To show the danger of reporting only part of the information.

D. To warn us of the harmful substance around us.

Relative information is often left out because ___________________.

A. it is not important

B. the author is trying to show what he or she says is true

C. readers will consider other important information

D. readers are able to form an opinion with half-truths

What can we learn from the passage?

A. Some measures must be taken to protect our dangerous world.

B. The growing trend of reporting only half-truths is getting out of control.

C. Teenagers ought to improve their ability of telling right from wrong.

D. We should learn to think critically and look at problems from all sides.

What causes traffic jams? Too many cars，right? No! Some Brits are now saying that trafficlights are to blame for much of the congestion.

They suggest that traffic lights be removed at busy roads．They believe people are a better judge of when it’s safe to go，not a traffic light programmed by an absent regulator．

A report from the Institute of Economic Affairs，a UK think tank（智囊团），argues that

abolishing traffic signals would decrease congestion，reduce exhaust（废气）emissions（排放）and improve safety．

The report said that removing lights should also prevent other bad behavior caused by signals．such、as speeding up to catch a green light It would also avoid the wasted time when drivers have to sit at a red light even if no one is using the green

The idea may sound strange，but it’s not new．Seven cities and regions in Europe are experimenting with no-lights roads．

Drachten in the Netherlands has gotten rid of 16 of its traffic light crossings and changed the other two to roundabouts under a“shared space”scheme．At crossings, cyclists dutifully raise their arm when they want to make a turn，and drivers follow a first．arrived，first．through approach and communicate by hand signs，nods and waving．The result? Typical journey time has been cut in half and accidents and congestion have mostly disappeared．

There have been small collisions but no problem，said Hans Monderman，creator of the scheme．“We want small accidents，in order to prevent serious ones．It works well because it’s dangerous．The driver has to be responsible for his or her own risk

“The many rules take away the ability to be considerate”Monderman added．“We’re losing our responsibility for socially responsible behavior．”

So far，Drachten’s locals have called the experiment a success．“I am used to it now，”said Helena Spaanstra．24．“You drive more slowly and carefully．but somehow you seem to get around town quicker．

Tony Ooostward，70，was equally enthusiastic．“I am a walker and now you are the boss at the crossroads，everyone waits for you．But at the same time walkers wait until there are a number of people wanting to cross at the same time．”

Owen Paterson，UK’s Shadow Transport Minister。visited Drachten．He said Britain should learn from the model．“The idea is to create space where there is mild anxiety among everyone so they all behave cautiously．No one drives fast along a busy street thinking that they have right of way．”

The model is being tested in London’s Kensington neighborhood．

Last year my wife and I spent a most interesting month in Turkey. Before we left, we were reminded of the difficulties of driving in Turkey. We certainly did not find this to be the case and, except for a few places in faraway mountainous areas, the roads were wide, and well-paved (铺). We drove for 12 days along the Western Coast of Turkey and had no problems at all. We found the Turkish drivers very polite and well-educated. We also found that eating lunch in the smaller towns was difficult so we picnicked almost every day.

The following day after our arrival was Turkey’s Children’s Day, started by Mustafa Kemal Ataturk. Ataturk loved children and he often said, “Children are a new beginning of tomorrow.” He even devoted the day 23rd of April to the children which today is celebrated as Children’s Day as well as the date when the Republic of Turkey was founded.

On that day certain children are picked to take over the places of the government, and a lucky kid will be the president of Turkey for a whole day. He can decide what’s going to happen and whether or not he is going to have the president next to him. There are a very large number of possibilities of things he can do but some shops aren’t open because they are celebrating the day as well.

All in all, it was a more enjoyable trip. I would recommend (推荐) a trip to Turkey to anyone with an adventurous spirit!

Before the author and his wife went on a trip to Turkey, they were told that ________.

A. it was difficult to travel in Turkey

B. it was not easy to drive in Turkey

C. the streets in Turkey were dangerous

D. there were many mountain roads

What do we know from the first paragraph?

A. Places in mountainous areas were difficult to reach.

B. It took the couple 12 days to drive to Turkey.

C. The Turkish drivers had good manners.

D. It was difficult to eat meals in Turkey.

The underlined word “He” in paragraph 3 refers to “________”.

A. everyone of us B. the government

C. the president of Turkey D. the lucky child

What can be inferred(推断) from the passage?

A. The couple had little difficulty making their way in Turkey.

B. Turkey doesn’t celebrate International Children’s Day.

C. The author joined in celebrating Turkey’s Children’s Day.

D. On Turkey’s Children’s Day, everyone had holidays.
