18、ustralian scientists. 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. “A

19、ll other group members 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 lar

20、ger competitor, it 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 volunta

21、rily, by restraining 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 avo

22、id fights, over having 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

23、, so keeping their 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 (等級的) societies remain stable. The research has proved the fact

24、that voluntary dieting 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 at

25、tractiveness, rarely 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，無奇不有。人節(jié)食是為了苗條，有魅力。魚節(jié)食又是為何？作者從魚類與人在節(jié)食問題上的對比，揭示出了一個令人深思的話題——人類的節(jié)食真是發(fā)自內心的嗎？其本質目的何在？ 1．When a goby grows to within 5-10% of the size of its larger competitor

A．the fish beaten up B．the fish found o

27、ut C．the fish fattened up D．the fish driven away 答案：D　詞義猜測題。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

28、extra food D．challenged the boss fish 答案：B　推理判斷題。文章第四段結尾the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast說明刺鰭魚的節(jié)食是自愿的。而第六段更指出小一點兒的刺鰭魚節(jié)食對于維護魚類社會穩(wěn)定的重要性。 4．What is the text mainly about? A．Fish dieting and human diet

29、ing. B．Dieting and health. C．Human dieting. D．Fish dieting. 答案：D　主旨歸納題。文章主要論述了刺鰭魚節(jié)食的問題。指出這一行為是它自愿的，一種目的在于維護它們的整體穩(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.
