2020屆高考英語基礎鞏固復習教案
you’d be wrong.
for my body to finish such a surprising task, i would have to be a mouse. not just any mouse, but one lucky enough to be involved in a new study at baylor college of medicine in houston.
after identifying an enzyme(酶)that allows fat to be stored in the body, scientists fed mice without those enzymes, and found those mice were able to consume far more food than other mice—and still weigh 10 to 15 percent less.
best of all, the mice that had no enzymes were in very good health, producing baby mice with no problem and generally acting like any other mouse. that’s great news for obesity researchers, who think that scientists may figure out a way to prevent the fatmetabolizing(脂肪代謝)enzyme in humans and control weight gain. and such a pill would be very exciting for many struggling to get rid of dangerous extra pounds.
but don’t start planning any big dinner just yet: at this point, of course, any pill for humans is but a twinkle(閃爍) in the eye of every medicine company’s ceo. more tests are to be made, and eventually humans will be introduced in the test.
but for now,unfortunately,control in diet is still the key.
【解題導語】 想品嘗美味又害怕體重增加?休斯敦貝勒醫學院的一項實驗將會幫你消除這個顧慮。

a.eating a lot of food while losing weight.

c.because the mouse has a very good metabolism.
d.because the author wants to try the food without the enzyme.
解析:選b。細節理解題。作者在第四段指出要想多吃還不胖,除非變成休斯敦貝勒醫學院減肥實驗中所用的那只老鼠,故選b項。
7.in the experiment, the mice without those enzymes ________.
a.were in good condition
b.put on weight
c.became weak
d.could not have baby mice
解析:選a。細節判斷題。根據第六段第一句話可知,沒有酶的老鼠的身體仍然健康如故,能繁育后代,行為與其它老鼠并無兩樣,故選a項。
