That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientis

18、ts. The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding (繁殖) rights within the group，” explains Marian Wong. “All other group mem

19、bers are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.” The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it

20、 causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up. It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraini

21、ng how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over ha

22、ving a feast. The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their

23、 competitors small. While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical (等級(jí)的) societies remain stable. The research has proved the fact that voluntary die

24、ting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature，” the researchers comment. “Data on human dieting suggest that, while humans generally diet to improve health or increase attractiveness, rare

25、ly does it improve long-term health and males regularly prefer females that are fatter than the females' own ideal.” 文章大意：大千世界，無(wú)奇不有。人節(jié)食是為了苗條，有魅力。魚(yú)節(jié)食又是為何？作者從魚(yú)類與人在節(jié)食問(wèn)題上的對(duì)比，揭示出了一個(gè)令人深思的話題——人類的節(jié)食真是發(fā)自內(nèi)心的嗎？其本質(zhì)目的何在？ 1．When a goby grows to within 5-10% of the size of its larger competitor, it ________. A

26、．faces danger B．has breeding rights C．eats its competitor D．leaves the group itself 答案：A　細(xì)節(jié)判斷題。文章第三段指出：當(dāng)稍小一些的魚(yú)一旦長(zhǎng)到它競(jìng)爭(zhēng)者體積的5～10%時(shí)，將引發(fā)戰(zhàn)爭(zhēng)。結(jié)果大多是小一點(diǎn)的刺鰭魚(yú)被逐出群體，最終被吞食掉。 2．The underlined words “the evicted fish” in Paragraph 3 refer to ________. A．the fish beaten up B．the fish found out C．the fish fat

27、tened up D．the fish driven away 答案：D　詞義猜測(cè)題。緊承前一句．..which usually ends in the smaller goby being driven away from the group可知the evicted fish指的是被逐出群體的挑戰(zhàn)失敗者。 3．The experiment showed that the smaller fish ________. A．fought over a feast B．went on diet willingly C．preferred some extra food D．chal

28、lenged the boss fish 答案：B　推理判斷題。文章第四段結(jié)尾the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast說(shuō)明刺鰭魚(yú)的節(jié)食是自愿的。而第六段更指出小一點(diǎn)兒的刺鰭魚(yú)節(jié)食對(duì)于維護(hù)魚(yú)類社會(huì)穩(wěn)定的重要性。 4．What is the text mainly about? A．Fish dieting and human dieting. B．Dieting an

29、d health. C．Human dieting. D．Fish dieting. 答案：D　主旨?xì)w納題。文章主要論述了刺鰭魚(yú)節(jié)食的問(wèn)題。指出這一行為是它自愿的，一種目的在于維護(hù)它們的整體穩(wěn)定的行為。 B (2014·寧波六校高一期中) In the UK, most children have their midday meal at school, but in many schools, parents can choose what their children eat. The children can have a school lunch－a hot, cooked

30、 meal; or they can take a packed lunch with them, which usually includes cold food like sandwiches. Often parents prepare lunches on_the_basis_of what their children want. Cathy, a mother of three children, told us, “My children have packed lunches, because they say they hate school dinners. I make

31、 3 packed lunches every morning, so we're like a sandwich bar in our kitchen in the morning.” However, another mother, Susan, made her choice based on the nutritious value of the food. She said, “My daughter always has school dinners. I think she probably gets healthier food by having a cooked lunc

32、h at school than she would if I made sandwiches.” But how healthy are school dinners? Kaz, a father, wasn't impressed with them. “Fizzy (有泡沫的) drinks were offered and I think there were a lot of chips.” The question of how healthy school food is was brought to Jamie Oliver, who launched a campaign

33、 to improve children's nutrition, after spending a year working in a school kitchen. The TV series about the campaign won an award this week. He was horrified(驚恐的)at the junk food he saw being served, which included burgers, pizza and chips.He decided to ban the junk, and started cooking good stews

34、(燉菜)and curries for the children instead. Jamie improved the school dinners in that particular school, and trained the dinner ladies to cook healthy food. Then he put pressure on the government to improve the standards of school food across the country. And it looks as if the changes have begun. 文

35、章大意：你討厭學(xué)校提供的飲食嗎？讓我們看看英國(guó)學(xué)校的情況如何？ 5．What would be the best title for the passage? A．School Dinners B．Healthy Food C．Dinners in the UK D．Research on Dinners 答案：A　主旨大意題。全文講述的是學(xué)校飲食的問(wèn)題，所以A項(xiàng)符合。 6．The underlined phrase “on the basis of” in the second paragraph probably means“________”． A．by compariso

36、n B．a(chǎn)ccording to C．in spite of D．for the good of 答案：B　猜測(cè)詞義題。所在句句意為“通常父母會(huì)按照孩子的要求準(zhǔn)備午飯”。 7．We can learn from the passage that________. A．in Britain, all children have their lunch at school B．Cathy's children like school dinners C．stews and curries are healthy food D．Jamie Oliver works in a scho

37、ol kitchen 答案：C　細(xì)節(jié)理解題。由倒數(shù)第二段可知，Jamie非常吃驚地發(fā)現(xiàn)學(xué)校提供漢堡包、比薩和薯?xiàng)l這些垃圾食品。他決定禁絕這些垃圾食品，用stews和curries來(lái)代替垃圾食品，所以不難看出stews和curries是健康的飲食。 8．Which of the following can be inferred from the passage? A．There are many schools in Britain. B．Susan chooses food for her daughter according to its nutrition. C．In the past, the food provided by British schools was not healthy enough. D．None of the parents in Britain like school food. 答案：C　推理判斷題。由最后兩段可推知，過(guò)去，英國(guó)學(xué)校提供的飲食是不健康的。
