Go to bed right away. Forget you need to get up as early as you can _ the early train?A. catch B. catching C. caught D. to catch选D27.Please eat foods which a lot of vitamins and minerals, brown rice.A. contain, includingB. hold, containingC. keep, containingD. include, including【答案】A【解析】【详解】考查动词词义辨析。句意：请吃含有大量维生素和矿物质的食物，包括糙米。contain可用于表示包含所含之物的全部或部分，而include则只能用于表示所包含之物中的一部分。hold指“能容纳”，keep指“保存”。故选A。28.I will never forget such a beautiful place I spent my childhood there with my grandparents.A. that B. where C. because D. in which【答案】C【解析】【详解】考查连词。句意：我从不会忘记这样一个漂亮的地方，因为我和祖父母在那儿度过了我的童年。根据空格后的部分是一个完整的句子，前后为因果关系，because在这里引导原因状语从句。故选C。【点睛】这是一个陷阱题，稍不注意就会因前面的suchthat，而误选A，但suchthat是如此以致于的意思，不合题意；有的同学看见空白前有一个place，以为后面是定语从句，而误选C。实际上，空格后的部分是一个完整的句子，前后为因果关系，because在这里引导原因状语从句。29.-English has a large vocabulary, hasnt it?-Yes. more words and expressions and you will find it easier to read and municate.A. Know B. Knowing C. To know D. Having known【答案】A【解析】【详解】考查动词。英语有大量的词汇，不是吗？是的，知道的单词与短语越多，你将发现阅读和交流就会变得越简单。根据对空缺处句子的分析可知，本题考查的是祈使句（表条件）+and+主句（表结果）这一结构，所以 morewordsandexpressions知道的单词与表达方式越多应是一个表示条件的祈使句，此处需要填动词原形，故选A30.The talk failed because no one could a solution accepted by both sides.A. make up with B. put up with C. keep up with D. e up with【答案】D【解析】【详解】考查动词短语词义辨析。句意：会谈失败了，因为没有人能提出接受双方的解决方案。A. make up with与 . 重修旧好；B. put up with容忍；C. keep up with跟上；D. e up with提出。故选D。31.The river was once with fishes, but now we find as a result of pollution.A. alive, none B. lively, nothing C. live, none D. living, nothing【答案】A【解析】【详解】考查形容词和代词。句意：这条河中曾经生长着各种各样的鱼，但是现在，由于污染，我们一条鱼也看不到了。第一个空用be alivewith表示“充满着”；第二个空用none表示数量概念，意为“一个也没有”。nothing表示“什么也没有”，不合题意。故选A。【点睛】alive, living, live和lively比较：alive是表语形容词，作“活着的”，“在世的”解，它既可以修饰人也可以修饰物；living意为“活着的”，主要用作定语，常置于名词之前，有时也可置于名词之后。也可用作表语；live意为“活着的”，可以作定语，放在所修饰的名词之前，一般不用来修饰人；lively意为“生动的”，“活泼的”，“充满生气的”，用作表语或定语，可以用来修饰人或物。32.-Did Jack e back early last night?-Yes. It was not yet eight oclock he arrived home.A. before B. when C. that D. until【答案】B【解析】【详解】考查连词。句意：杰克昨晚回来得很早吗？是啊，他到家的时候还不到8点。before在之前；when当的时候；that那个；until直到；根据答语中的yes可知，要表现Jack昨晚早早就回家了，不能用notuntil，因为它是指直到8点才到家；如果要使用强调句型It wasthat，应在强调的部分not yet eight oclock前加上介词at才行，故用when引导时间状语从句最合适，译为还未8点就到家了。故选。33.By the time he was 14, he advanced math on his own. It was the reason that he could answer the difficult math problem.A. studied B. had studied C. was studying D. has studied【答案】B【解析】【详解】考查时态。句意：到他14岁的时候，他自己学过高等数学。这就是他能解答这道难题的原因。bythetime+一般过去式，主句一般用过去完成时。故选B。34.All the staff in our pany are considering _ to the city centre for the fashion show.A. to go B. going C. to have gone D. having gone【答案】B【解析】【详解】考查非谓语动词。句意：我们公司所有的员工都在考虑去市中心看时装表演。此处consider的意思是“考虑”，后接名词或动名词，considering sth./doing sth“考虑某事或做某事”，故选B。35. -You have to believe in yourself. No one else will, if you dont.- _. Confidence is really important.A. Its not my cup of teaB. Thats not the pointC. I dont think soD. I couldnt agree more【答案】D【解析】句意：你得相信自己。如果你不相信自己，没有人会相信你。我非常赞成，信心真的很重要。依据答语第二句可知答话人非常同意对方的观点。I cant/couldnt agree more意为“我太同意你(的观点)了”。III. 完形填空(共 20 小题；每小题 1 分，满分 20 分)阅读下面短文，掌握其大意，然后从各题所给的四个选项中，选出最佳选项，并在答 题卡将该项涂黑。The Price of a DreamI grew up poor-living with my wonderful mother.

When a scientist observes some phenomenon(现象)in nature he develops an idea, called a theory or hypothesis(假设). Then he does an experiment to test his hypothesis. If the results are as expected, then the experiment confirms the hypothesis. If the experiment fails and the results are not as expected, then the experiment disproves the hypothesis and the scientist must e up with a new theory to test.In ancient times great thinkers came up with plex theories to explain nature, but did not always prove them by experiment. For example, the great Greek thinker Aristotle, for centuries, had a theory that heavy objects would fall faster than light objects until the scientist Galileo performed an experiment and found it had been wrong.Heres an experiment that you can use to prove o
