According to the article, As overall growth slows down, the circadian clock ensures that the plant reacts more strongly to light early in the morning than in the afternoon or evening, so it gradually stops moving westward during the day.The researchers compared full-grown flowers facing east with those they turned to face west, and found that east-facing flowers attracted five times as many helpful pollinators. Thats because the east-facing flowers heat up faster and bees like warm flowers.Just like people, plants depend on the daily rhythms of day and night to function, Anne Sylvester, director of the National Science Foundations Plant Genome (基因组) Research Programme said in a press release. Sunflowers, like solar panels, follow the sun from east to west. These researchers explore information in the sunflower genome to understand how and why sunflowers track the sun.UC Berkeley professor and co-author of the study, Benjamin Blackman, believes that the connection between circadian rhythms and growth could be applicable to other researches. The more general point, that one of the circadian clocks adaptive functions is to regulate the timing and strength of growth responses to environmental signals, is one that I think will apply to a broad range of qualities and species, he said.1. What did the researchers discover when they tied the sunflowers up?A. They still tracked and faced towards the sun.B. They grew faster during the daytime than they did at night.C. Their growth rates were lower than those of flowers facing the sun.D. The growth rates on the west side were higher than those on the east.2. Why do sunflowers move westward less when they are fully-grown?A. Because they will not be affected by light anymore.B. Because they would stop growing up if they faced west.C. Because they are not active at all during afternoons or evenings.D. Because they are more sensitive to light in the early morning from the east.3. What may the underlined word pollinators (Para. 7) refer to?A. Bees.B. Plants.C. Energy.D. Researchers.4. What is the possible direction of future study, according to Benjamin Blackman?A. Exploring information in the sunflower genome.B. Comparing humans circadian rhythms with sunflowers.C. Comparing full-grown flowers facing east with those facing west.D. Exploring how circadian rhythms affect the growth of other species.二、选择题。阅读下面的短文，从短文后的选项中选出能填入空白处的最佳选二、选择题。阅读下面的短文，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。项。选项中有两项为多余选项。The Lion King vs Real LionsThe lions in Disneys live-action remake of The Lion King may look realistic, but if you examine them carefully, you will find that they differ from real lions in many ways. (5) _ The changes include the way they look, their social structure, and their behaviour in the 1994 animated film and the live-action remake.(6) _ Lets take a closer look at some key aspects of lions behaviour, coupling patterns, and eating habits to see how different the Disney live-action remake is from real life.A pride of lions (狮群) is a very closely-connected community, with female lions taking the leading role. (7) _ It comes down to a matter of genetic diversity and the need to ensure healthy bloodlines among the species. With female lions rarely leaving the pride, male lions will frequently travel, produce young, and move on.A pride is unique in that it is a very closely-connected social group, so it requires a lot of interactions to keep everyone on the same page. (8) _ Not only are they raising lion cubs (幼崽), socializing with other lions, and hunting, but they are also in charge of overseeing the space they occupy. If a particular pride gets too big, its the female lions who will find a new territory for the group to settle in where everyone can live well.In The Lion King, Simba not only makes friends with Timon, a meerkat, and Pumbaa, a warthog, but he is raised by them. (9) _ So the idea that Timon and Pumbaa are able to redirect his meat-eating tastes into eating insects and plants would never be realised in real life. A. With male lions coming and going, female lions are the ones who manage things at home.B. Male lions are not expected to stay in the same pride through their entire lives.C. Does the film show the real lives of lions?D. It is obvious that Disney made some changes to the lions to better fit the story.E. But lions are considered to physically grow up during the ages of two to four.F. However, in real life, lions are meat-eaters by nature.G. Male lions have to stay in the territory theyve grown up in.写作模块写作模块一、书面表达。一、书面表达。10. 观察一下你身边环境所发生的变化，写一篇短文，要点如下：（1）你身边的环境发生的变化；（2）导致变化的原因；（3）你对此的想法。注意：（1）词数不少于 120；（2）可以适当增加细节，以使行文连贯。二、翻译题。使用括号中所给的提示将下列句子翻译成英文。二、翻译题。使用括号中所给的提示将下列句子翻译成英文。11. 因为其他的大学和我的首选大学一样优秀，所以我很难做出最终决定。（first choice）12. 我昨天到达剧院的时候，售票处已经挤满了人。（be crowded with）13. 这一直是我最喜欢的一部电影。（of all time）14. 连日的大雨吓退了想去沙滩的游客们。（drive away）15. 地质学家们收集了各种各样的样本来做研究。（a variety of）答案：答案：阅读模块阅读模块一、1.

It was so impressive that I used to think that the song Twinkle Twinkle Little Star was the most beautiful song in the world. However, as I grew up, I seldom saw any stars in the sky. Hearing a mom singing Twinkle Twinkle Little Star to her little baby has become so strange.What has caused the disappearance of the shining stars? The answer is air pollution. When the sky is grey, everyone wears a mask or stays indoors to keep away from the heavy smog.Hopefully, the government and citizens can all take steps to change the situation and make this world a better place. I am sure that the disappearing stars are also not willing to say goodbye and they will be twinkling in the sky again some day.二、11.
