D
At age 61, identical twins Jeanne and Susan no longer look exactly alike. Susan smoked for many years and is an admitted sun worshipper, whose habits Jeanne does not share. A new study of twins suggests you can blame those coarse(粗糙的)wrinkles, brown or pink spots on too much time in the sun, smoking, and being overweight.
Because twins share genes, but may have different exposures to environmental factors studying twins allows an “opportunity to control for genetic susceptibility(易受影响性),” Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and his colleagues explain in the latest issue of Archives of Dermatology.
Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is related more to environment and lifestyle than genetic factors.
But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk.
Baron’s team examined facial skin of 130 twins, 18 to 77 years old, who lived mostly in the northem Midwest and Eastern regions of the US, who were attending the Twins Days Festival in Ohio in August 2002. At this time, each of the twins also separately reported how their skin burned or tanned(晒黑)without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking. The study group consisted of 52 fraternal(异卵双生)and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status.
From these data, the researchers noted strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental damage. By contrast, sunscreen use and drinking alcohol appeared related to less skin damage.
Baron and his colleagues say the current findings, which highlight ties between facial aging and potentially avoidable environmental factors—such as smoking, being overweight, and unprotected overexposure to the sun’s damaging rays—may help motivate people to minimize these risky behaviors.
67.Which of the following is true according to the passage?
A.Jeanne and Susan share all the habits including smoking.
B.Skin aging is related more to environment and lifestyle than genetic factors.
C.Only identical twins can take part in the research.
D.Sunscreen use cannot help people have less skin damage.
68.Why did Baron’s team do the research on twins?
A.Twins are more likely to suffer from skin cancer.
B.It may guarantee the research is not influenced by genetic factors.
C.It gives others an opportunity to control twins’ genes.
D.It helps find twins are exposed to different environments.
69.What can you infer from the last paragraph?
A.This research makes people aware of dangerous lifestyles.
B.The environmental factors are unavoidable.
C.Being exposed to the sun is absolutely damaging.
D.There is little relationship between skin aging and environment.
70.The passage is mainly concerned with___________
A.skin cancer and environment
B.identical twins research
C.aging skin and environmental factors
D.genes and lifestyles

There were times when it was only schoolchildren who felt sick before they got their grades.
71
Many teachers are opposed to it. They don’t mind being evaluated. But they are upset because the results are then being posted on the Internet and accessible to millions of Internet users. 72 The teachers are graded on categories such as “motivated”, “good instruction”, “easy examinations”, or even “sexy”. 73
The creators of the website say that the students are only being offered the chance to provide teachers with some feedback(反馈)about their classroom instruction. Bernd Dicks founded the website with three friends. 74 On a grading scale of one to six, the teachers’ average grade is as high as 2.7 and it has been improving lately. He often says the impression is that students are bullying(欺负)their teachers. But there is also bullying of the students by teachers.
“Teachers must also learn to live with criticism,” he added. But still, the website is not totally prevented from being manipulated(人为操纵), as one teacher near the northern city of Hanover recently proved. 75 Within a few days, seven of his colleagues were listed in the top 10 rankings of Germany’s best teachers.
On the website www. spickmich. De during the past four months students have posted evaluations of 100,000 teachers.
A.He registered himself on the website as a student and then rated his own teaching colleagues highly. |
B.Many teachers think that their privacy has been disturbed. |
C.But now teachers in Germany are scared, too, as they are being graded by their students. |
D.He says that the students are largely quite satisfied with their teachers. |
F.He tried to make friends with students as many as possible.

I’m a pig, and my son is a rabbit. I have snakes for daughters, and my wife, believe it or not, is a dragon! Do I live in a zoo? No, of course not! I am talking about Chinese zodiac signs. Depending on the year of your birth, each person has an animal for a sign. That’s why I am a pig and my wife is a dragon. If you, like me, were born in the year of the pig, then you are brave, thoughtful and loyal. The year of the pig is filled with good fortune.
Now let’s take a closer look at this interesting animal.
Pigs were first raised by man about 9,000 years ago, and are still a very common farm animal in many parts of the world. We don’t just use pigs for their meat — almost every part of the animal is used. The hair is used for artists’ brushes. The fat is used to make floor wax, rubber and plastics.
Pigs have also been important in the world of entertainment. In 1995 the film ‘Babe’ starred a loveable talking pig as its main character. The film won an Oscar and was nominated for 6 more. In England you can even go to watch pig racing. A farmer, Rob Shepherd, has been raising money for charity by holding pig races on his farm. The events have been very successful. People don’t just want to eat pigs, it seems!
Pigs also play an important role in the English language. For example, if someone says that he will travel to the sun one day, you can say “pigs might fly!” to him. Hungry? Well then, you can “pig out” and eat lots of food. And what if someone rescues you? Well, you can say that they “saved your bacon”.
44. The writer wrote the first paragraph in a ______ tone.
A. sad B. confused C. serious D. humorous
45. We may know from the passage that ______.
A. people in England like pigs more than other animals
B. pigs are more useful than ordinary people imagine
C. pigs are the first animals raised by man
D. more people don’t want to eat pigs now
46. The underlined sentence “pigs might fly!” in the fifth paragraph means “______”.
A. What you have just said is impossible
B. Pigs are great animals
C. I don’t understand your words
D. I can’t agree with you more
47. Which diagram shows the structure of the passage?
A B C D
C
Celebrations spread across China when Shanghai, the Oriental Pearl, was given the right to host the 2010 World Expo on December 3. Shanghai won the honor after beating rivals from Russia, Mexico, Poland and South Korea.
“I’m very proud of being Chinese,” said Wang Kaibo, a Senior 2 student of the Middle School Affiliated (附属的) to Beijing Medical University. “The winning of the expo is a victory, not only for Shanghai residents, but for the people of the whole Chinese nation.”
Bidding for the expo shows that China is more confident of playing a more important role on the international stage. It’s competing for large events and the next one could be the World Cup, Wang said.
The World Expo 2010 and the 2008 Beijing Olympics will become the twin shining stars of China’s development over the next 10 years, said experts. The World Expo is known as “Olympics of the economic, cultural, scientific and technological fields.” It is usually held every five years and lasts for six months. The Olympics, World Cup and World Expo are considered three top international events in the world.
China is the first developing country to win the expo bid in the event’s about 159-year history. Not only will it attract more foreign investment to China, but experts say that the half-year-long exhibition will bring at least 70 million visitors to Shanghai.
The expo was first held in London in 1851. It has a history of global influence. The Eiffel Tower, built during the Paris World Expo in 1889, became the symbol of the French capital.Many historic inventions, such as the telephone and airplane, all made their first appearance at a World Expo.
48. What does the word in bald “rivals” probably mean in the second paragraph?
A. competitors. B. enemies. C. players. D. supporters.
49. The winning of bidding for the World Expo 2010 and the 2008 Olympic Games implies ______.
A. China is beginning to play a more important part on the international stage.
B. China has played the most important role in the international affairs.
C. China has become a developed country for many years.
D. China is the first Asian country to win the expo bid in history.
50. As we know, in general, the Word Expo is usually held every ______ years, while the Olympics is usually held every ______ years.
A. 4;5 B. 5;4 C. 4;4 D. 5;5
51. By bidding for the expo and the Olympics, we are sure that ______.
A. China will beat rivals from Russia, Mexico, Poland and South Korea
B. China will become a super country in the United Nations
C. China will build a famous tower like Eiffel Tower as the symbol of the capital
D. China will develop more quickly than before and will benefit a lot from them

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中的两项为多途选项。
Many people think of guys as being carefree when it comes to their appearance. But in fact, a lot of guys spend plenty of time in front of the mirror. They care just as much as girls do about their body image.
Body image is a person’s opinions and feelings about his or her own body and physical appearance. 71 . You appreciate your body for its capabilities and accept its imperfections.
72 . Here are some ideas:
Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking, dancing, or even running. Or perhaps you have non-sports skills, like drawing, painting, singing, playing a musical instrument, writing, or acting, 73 .
Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques (体形) don’t just happen. 74 . A healthy habit can be as simple as exercising 20 minutes to 1 hour three days a week. Working out can also lift your spirits.
Respect your body! Practicing good habits ---- regular showering; taking care of your teeth, hair, and skin; wearing clean clothes, and so on ---- can help you build a positive body image.
75 . Your body is just one part of who you are. Your talent for comedy, a quick wit (智慧), and all the other things make you unique. So try not to let small imperfections take over.
A.Use this as an opportunity to discover what you’re good at. |
B.Be yourself. |
C.Having a positive body image means feeling satisfied with the way you look. |
D.Just explore talents that you feel good about. |
F. The good news is that self-image and body image can be changed.
G. So, what can you do to develop a positive body image?
