7、u more awake and ready to handle whatever is ahead of you for the day. 锻炼使你在白天保持清醒,随时处理你面前的任何事务。 分析:exercising是动词-ing形式作主语。awake和ready是两个形容词,作宾语补足语。whatever is ahead of you是及物动词handle的宾语从句。whatever相当于anything that.,-7-,【语篇导读】本文是一篇说明文。锻炼身体的好处很多,尤其是早上锻炼,会让你一整天都容光焕发。文章主要介绍了锻炼给我们带来的各种好处,最后作者呼吁大家:定好闹钟,早起

8、锻炼吧! 36.G 此句为过渡句,承上启下。根据下文的“Working out in the morning provides additional benefits beyond being physically fit.”可知,此处要表示“假如你计划定期锻炼,或者现在正在锻炼的话,那么听好了”,故选G项。 37.E 此句为总结句。根据上文可知,此处讲述的是锻炼会使你更加清醒,而E项表示“锻炼之后,你可以保持头脑清醒4至10小时”,与前文相吻合,故选E项。 38.F 此句为段中承上启下的过渡句。根据本段开头提到的“Your metabolism(新陈代谢) gets a head start

9、.”以及后面的“.getting the calorie(卡路里) burning”可知,此处表示“锻炼之后,在一整天里你都会继续燃烧卡路里。”故选F项。,-8-,39.B 此句为主题句。根据后文可知,研究表明,早起锻炼的人的睡眠质量要好于晚上锻炼的。故此处是指“你的睡眠质量会提高”,故选B项。 40.A 此句为主题句。根据后文可知,如果你早上锻炼的话,你更可能一整天都保持健康的饮食习惯。此处表示“会让你坚持自己的饮食习惯”,故选A项。,-9-,A (2018山东临沂三模) The color of animals is by no means a matter of chance;it de

10、pends on many considerations,but in the majority of cases tends to protect the animals from danger by making it less outstanding.Perhaps,it may be said that if coloring is mainly protective,there ought to be fewer brightly colored animals.1. .The kingfisher itself,though so brightly colored,is not e

12、some of which are brown.This probably makes the caterpillar even more outstanding among the green leaves.What would you do if you were a big caterpillar?Why,like most other defenseless creatures,you would feed by night,and lie hidden by day.4. .When the morning light comes,they go down the stem of t

13、he food plant,and hide among dry sticks and leaves near the ground,and it is obvious that under such circumstances the brown color really becomes a protection.While we may say as a general rule that large caterpillars feed by night and hide by day,it is by no means always the case that they are brow

16、后面的举例却是颜色鲜艳的动物也不容易被发现,所以空格处应该是承上启下、语义转折的逻辑语句。 2.D 考查主旨概括语句。本段主要描述沙漠中的动物如何让自己身体的颜色保护自己。所以空格处应该是主题句,故选D项。 3.G 考查逻辑性语句。空格处前面内容是:沙漠几乎没有为动物提供保护的地方。空格处是沙漠的这种特点给生活在沙漠中的动物带来的影响,而且G项中的sand color与主题句和其他句中都重现了。,-13-,4.A 考查逻辑性语句。空格前面的内容是:大多数没有自卫能力的动物都是昼伏夜出,空格后面对毛虫习性的描述也一样,所以此处用A项“So do these caterpillers”作为过渡性语

17、句,作为由一般到特殊的典型行文结构。 5.E 考查逻辑性语句。空格前面的内容是:并不是所有的毛虫都呈棕色,有一些仍然是绿色的。空格处既解释“有些毛虫仍然是绿色”的原因,又与and后面的分句构成并列。,-14-,B (2018江西南昌二模) Last week the electricity in my flat went out.I had just got home from work and was happily making my tea,when all a sudden I was surrounded by complete darkness.I tried to fix it

I use electricity all the time,even when its not really necessary.,-15-,4. It contributes to global warming.It is harming our environment and we need to do what we can to stop

20、it.Not only that,but if we continue to use the same large amount of energy we will soon run out.
