I used to hate being called upon in class mainly because I didn't like attention drawn to myself. And __41__ otherwise assigned (指定) a seat by the teacher, I always __42__ to sit at the back of the classroom.

All this __43__ after I joined a sports team. It began when a teacher suggested I try out for the basketball team. At first I thought it was a crazy __44__ because I didn't have a good sense of balance, nor did I have the __45__ to keep pace with the others on the team and they would tease me.

__49__ what I was doing. Sometimes I'd get __50__ and take a shot at the wrong direction —which made me feel really stupid. __51__,I wasn't the only one “new” at the game, so I decided to __52__ on learning the game, do my best at each practice session, and not be too hard on myself for the things I didn't __53__ “just yet”.I practiced and practiced. Soon I knew the __54__ and the “moves”. Being part of a team was fun and motivating. Very soon the competitive __55__ in me was winning over my lack of confidence. With time, I learned how to play and made friends in the __56__ — friends who respected my efforts to work hard and be a team player.

I never had so much fun!

With my __57__ self-confidence comes more praise from teachers and classmates.

I have gone from “__58__” in the back of the classroom and not wanting to call attention to myself, __59__ raising my hand — even when I sometimes wasn't 100 percent __60__ I had the right answer. Now I have more self-confidence in myself.

Toronto is a big and beautiful city,which has developed from a relative unknown place over the past half century to the center of culture,trade and communication in Canada.

With its colorful ethnic(种族的)mix,rich history and breathtaking buildings,Toronto offers non-stop adventures to the tourists. To get a sense of how big,various and magical Toronto is,the best place to start is the CN Tower,the tallest free-standing(无支撑物的)building in the world. From this point,visitors can get a bird's-eye view of the city's amazing scenery and unique geography.

In addition to being an important center of culture,trade and communication in Canada,Toronto is also a major multi-ethnic city. It has a population of over 4.5 million and its citizens come from countries around the world and from all manner

of ethnic backgrounds. Every day,in most places of the city,a hundred different languages can be heard on the streets,from Hindi to Greek to French. This,perhaps,explains why former Prime Minister Pierre Trudeau once said that Canada is really more mosaic(马赛克,镶嵌图案) of cultures and languages than a melting pot. Street signs in Toronto are mostly in English. Weekly and daily newspapers are published in various languages,and the city hosts successful international film festival each September. It is also home to a popular baseball team,the Toronto Blue Jays. Toronto has something for everyone.

The fiddler crab (蟹) is a living clock. It indicates(=shows) the time of day by the colour of its skin, which is dark by day and pale by night. The crab’s changing colour follows a regular twenty—four hour plan that exactly matches th e daily rhythm (节奏) of the sun.

Does the crab actually keep time, or does its skin simply answer to the sun’s rays, changing colour according to the amount of light strikes it? To find out, biologists kept crabs in a dark room for two months. Even without daylight, the crab’s skin colour continued to change exactly on time.

This characteristic (特性) probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies. After millions of years it has become completely regulated (受控制) inside the living body of the crab.

The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day

before. From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides (潮水). The crab’s period of greatest darkening is exactly the time of low tide on the beach where it was caught!

66. The fiddler crab is like a clock because it changes colour ______.

A in a regular 24—hour rhythm B. in answer to the sun’s rays

C. at low tide

D. every fifty minutes

67. The crab’s changing colour ______.

A. tells the crab what time it is

B. protects the crab from the sunlight and enemies

C. keeps the crab warm

D. is of no real use

68. When the fiddler crabs were kept in the dark , they ______.

A. did not change colour

B. changed colour more quickly

C. changed colour more slowly

D. changed colour on the same timetable

69. The crab’s colour—changing ability was probably developed ______.

A. in the process of evolution (进化)

B. over millions of years

C. by the work of biologists

D. both A and B

70. The best title for this selection would be ______.

A. The Sun and the Tides

B. Discoveries in Biology

C. A scientific Study

D. A Living Clock

A young British sailor was missing at sea yesterday in similar circumstances(情况) to the way his father died five years ago.

The dinghy(救生橡皮船),used to take Richard Smith,21,to his yacht(快艇),was discovered empty, floating in seas off the Caribbean island.An air and sea search was carried out but he has still not been discovered.

Richard’s mother, Bicknell,said from her home in Hampshire,“It’s so much coincidence.Richard always carried a photograph of his father attached to a poem,which included the date of his disappearance.”

“Now, it’s very strange because all they have found is Richard’s dinghy.We need to know this time what has happened one way or another.If you know at least you can go through the grieving process(悲痛的过程).”

In November 1996,Mr. Smith’s father, Charlie,was sailing in the Tasmen sea between the Australian mainland and the island of Tasmen with his new wife.They lost radio contact with the shore and they, together with their yacht were never seen again,and their disappearance remains a mystery.

Last night's meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothschild, Emerald Valley's mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city's lights that it darkened the light of the meteors passing overhead.

“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment.”

Astronomers—scientists who study stars and plan ets—have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.

There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats, frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark-Sky Association. “100 milli on birds a year throughout North America die in crashes with lighted buildings and towers.”

Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase a person's chances of getting cancer.

Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights

when we are not using them, so that other creatures can share the night.

76.It happened last night that ________.

A.the city's lights affected the meteor watching

B.the meteors flew past before being noticed

C.the city light show attracted many people

D.the meteor watching ended up a social outing

77.What do the astronomers complain about?

A.Meteor showers occur less often than before.

B.Their observation equipment is in poor repair.

C.Light pollution has remained unsolved for years.

D.Their eyesight is failing due to artificial lighting.

78.What the author concerned about according to Paragraph 4?

A.Birds may take other migration paths.

B.Animal's living habits may change suddenly.

C.Varieties of animals will become sharply reduced.

D.Animals' survival is threatened by outdoor lighting.

79.Lighting regulations in Flagstaff, Arizona are put into effect to ________.

A.lessen the chance of getting cancer B.create an ideal observation condition C.ensure citizens a good sleep at night D.enable all creatures to live in harmony

80.What message does the author most want to give us?

A.Saving wildlife is saving ourselves. B.Great efforts should be made to save

energy.

C.Human activities should be environmentally friendly.

D.New equipment should be introduced for space study.

The First Day in the Summer Holiday

It was the first day of the summer holiday, but Dingding wasn't happy. In the

morning, his mother woke him up early and wanted to take him to a make-up school.

At almost the same time, his father came in, telling him to sign up for an English

training course. Dingding was a football fan and was crazy for cartoon films, yet

neither of his parents would like him to develop his own interest. What they only

care about seems to be his study.

It's not only Dingding who has to face such a holiday. Nowadays, children in

China are burdened with so much homework and so many training courses that they can

hardly enjoy their holidays. It's time that parents “returned” holidays to their children.
