第三部分 閱讀理解(共20小題;每小題2分,滿分40分)

A

Gordon Ramsay is one of Britain’s best-known chefs. He is one of the only three chefs in the country to maintain three Michelin stars for their restaurant.

Gordon was born in Scotland but was brought up in England after his family moved to Stratford. He played football as a teenager for Oxford United Football Club’s youth side and was spotted by a scout(球探)for Rangers. He became a professional player at the age of 15. After a knee injury that left him unable to regain full fitness, he was released from the club.

At the age of 19 Ramsay now turned his hand to cookery. He worked under Marco Pierre White and Albert Roux in London and Guy Savoy and Joel Robuchon in Paris before becoming head chef of the newly-opened Aubergine restaurant in 1993. By 1996, the restaurant had been awarded two Michelin stars. In 1998 Ramsay opened his first own restaurant in Chelsea. The restaurant gained three Michelin stars in 1999, making Ramsay the first Scot to gain the achievement. From there his empire has expanded rapidly, opening a lot of restaurants.

Ramsay has published six books on cooking and also appeared in two documentaries(記錄片)―Boiling Point in 1998 and Beyond Boiling Point in 2000. The series showed that Ramsay is a hot-tempered man in the kitchen; he was seen yelling dirty words at his staff and throwing equipment around. Food critic Gill, who was famously fired from Ramsay’s Chelsea restaurant, has said that Ramsay is “a wonderful chef, just a really second-rate human being”.

56. Ramsay had to leave the club because ___________.

A. he wanted to be a cook                            B. he didn’t have a gift for football

   C. his knee was badly hurt                    D. his family moved to England

57. What’s the right order of the things that happened to Ramsay?

   a. opened his own restaurant                 b. appeared in Beyond Boiling Point

   c. received three Michelin stars              d. became a professional footballer

   A. a, b, c, d             B. a, c, d, b           C. d, a, c, b                  D. d, b, a, c

58. From the last paragraph we know that Ramsay is___________.

   A. an excellent chef as well as a respected man

   B. friendly and good at cooking

   C. a successful writer and a second-class cook

   D. is famous but hard to get along with

59. It can be learned from the passage that ___________.

A. Ramsay became a professional footballer at 15

   B. Three Michelin stars are awarded to the best restaurants

   C. Boiling Point and Beyond Boiling Point are Ramsay’s books

   D. Ramsay opened his restaurant after learning cookery

 

B

Residents of Golestan Province in northern Iran have one of the highest rates of esophageal cancer(食道癌)in the world. They don’t drink alcohol or smoke―the two primary risk factors for the disease in the west―but they do consume tea, nearly 1.2 liters per day, on average. So local researchers set out looking for a connection.

They employed 300 esophageal cancer patients who were diagnosed in the eastern part of Golestan and matched them up with 571 healthy controls who shared their age, gender and place of residence. All but one of them drank tea, and they gave interviewers information about their tea consumption and brewing habits.

Teaming up with investigators from the U.S., England, France and Sweden, the researchers calculated that people who said they drank “hot” tea (149 to 156 degrees Fahrenheit) were more than twice as likely to develop esophageal cancer as people who said they drank the beverage “warm” or “l(fā)ukewarm” (less than 140 degrees). Those who said they took their tea “very hot” (at least 158 degrees) were more than eight times as likely to get esophageal cancer, according to the study, published online Thursday in the British Medical Journal.

The scientists have now connected it with esophageal cancer. The problem doesn’t appear to be the tea itself, but the temperature at which it is consumed, their study found.

The researchers also asked people how long they waited to drink their tea after pouring it. Those who said they waited two to three minutes were nearly 2.5 times more likely to develop the cancer compared with people who said they waited at least four minutes. Impatient tea drinkers who waited less than two minutes were 5.4 times as likely to be diagnosed with esophageal cancer, the study found.

The study didn’t assess the mechanism linking hot tea to esophageal cancer, but the researchers said the temperature of the liquid was almost certainly to blame rather than the compounds in the tea itself.

60. According to the passage, ___________ were thought to be two main causes of esophageal cancer.

   A. drinking hot tea and smoking                          B. drinking alcohol and smoking

   C. working in the kitchen and smoking                 D. taking sunbaths and drinking alcohol

61. The underlined word “it” in Paragraph 4 probably refers to ___________.

   A. the tea they drink                                           B. the way people drink tea

   C. the temperature of the tea                               D. the properties of the tea

62. We can infer from the second paragraph that ___________.

   A. drinking tea causes the cancer                         B. few people drink tea in that area

C. 300 out of 571 people got the cancer                D. tea has no direct connection with the cancer

63. Which would be the best title for this passage?

   A. Drinking Tea with Patience                          B. An Esophageal Cancer Stricken Area

   C. Temperature and Esophageal Cancer                D. Various Causes of Cancer

 

C

The growing popularity of digital reading has encouraged best-selling young Chinese author Han Han to release (發(fā)表) his new novel on the Internet.

Ta De Guo (His Country), of which Han Han has finished only one tenth so far, will be available for paid reading from December 1st on Qidian.com, the online library has announced.

Han Han will update the story every day and finish the book before the end of the year. A printed edition will only be produced after all of the content goes online, sources said.

To read the entire book, readers will have to pay eight yuan, or 0.08 yuan per 1,000 words. This is almost four times the price of an average writer on Qidian.com.

Lu Jinbo, a well-known publisher, estimated that a popular writer like Han Han is likely to attract 20 million subscribers. That means this high-school-dropout-turned popular author could bring in 160 million yuan, nearly 40 times as much as he earned in copyright royalties (版稅) last year.

On the 2007 list of Chinese millionaire writers, Han Han ranked 13th with 3.8 million yuan. The richest, Guo Jingming, earned 11 million yuan.

Statistics from China Internet Network Information Center show that there are at least 253 million Internet users in China. Such a large-scale Internet population has developed a prosperous industry for online novel writing. Among the many success stories is Zhang Muye, an office worker whose fantasy novel Ghost Blows out the Light made him the 19th wealthiest author in 2007.

Besides the potential to gain a large readership base, the Internet writers are being recognized professionally. The jury(評(píng)委)of the Mao Dun Literature Prize, the most prestigious(有影響力的)honor for Chinese writers, is considering adding a category for online writers.

64. According to the passage, online writing is becoming more and more popular mainly because ___________.

   A. it’s a good way to save paper               B. it’s convenient to write online

Koalas are found only in Australia. Even if called koala bear, this animal has nothing to do with the actual bear; it is not even a mammal (哺乳動(dòng)物), but a marsupial (有袋動(dòng)物), like the kangaroo. Its closest living relatives are the wombats (毛鼻袋熊). A koala is about 60-80cm long and weighs 5-14kg.

The name “koala” means “no drink”, and refers to the koala’s ability to go for days without water. Koalas get the water content they need from the eucalyptus(桉樹(shù))leaves on which they feed. The koala is the only mammal with a digestive system that can feed only on eucalyptus leaves―incidentally, these leaves are highly poisonous if eaten by humans. One individual consumes about 5kg of eucalyptus leaves daily and it may never drink water!

The koala is a nocturnal mammal. They prefer to move around just after sunset, spending daytime sleeping in the fork of a tree. A koala spends sleeping 75% of its time. The eucalyptus leaves they eat are rich in fiber and poor in proteins and fats. The adult must detoxify(排毒)leaves with energy expense, while fiber is hard to break down. Because of this poor diet, koalas save energy by sleeping most of the day, while their movements are very slow.

Koalas only have one young per year. In summer, baby koalas are born about a month after mating. The female takes it with her mouth and places it into her poach. In 6 months, the young can get out and feed on leav
