7.They ______ about eight hundred English words by the end of last term.

C. are going to learned D. have learned

Answer 1

1.C因为every day.说明是一般现在时，又因为事情不是被发生的，是主动的，且事情是复数，所以are happening
2.D首先 haven't seen 说明是现在完成时，后面可以加for+一段时间和since+时间点，所以A不对，对
3.C 因为 came 说明过去时，又因为这句话表示. Catherine 已经写好信，在她妈妈进来前，所以是过去的过去。
用过去完成时
4在近几年，我们国家的经济取得了高速的发展。In resent years是在不久之前几年，表示已经增长了。。。。还会继续增长所以用现在完成时。不属于过去完成时的两种增长是主动，不是被“增长了。。”所以选B
5C吧因为 Mr. Johnson’s story 是被嘲笑，是被动的，而且嘲笑的固定短语是laugh at 所以C
6Bthere be句型， 故排除Athere be 句型的主语在后面，本句中是little rain 形容鱼要用单数形式，C D都是复数形式，不行。B采用的是完成时态，因为夏天天气怎么样是发生在提问之前，故用完成时
7D.因为后面的时间状语是by the end of last year。所以句子的时态应该是现在完成时，所以用have learned。
额，本人英语也不咋的，要是有错希望大家指出来，我会改的。望楼主采纳

追问

第5题假如有 is laughed at 可以选吗 还有 第四题我还是不明白为什么不选A

追答

第5题假如有 is laughed at 也不可以选，因为 heard 说明过去时呀
第四题4.In recent years , the economy of our country ____ rapidly.
A. is increased B. has increased
C. increased D. has been increased
首先In resent years是在不久之前几年，表示已经增长，所以用完成时，have在这里是助动词+down，就是现在完成时。be +down表被动，经济是被增长的明白吗，不是主动关系

追问

第7题为什么不选D

追答

上学期末为止，他们已经学了约800个英语单词。

这里的关键时间点是：by the end of last term(到上学期末为止）
所以，用的是过去完成时态的。D答案是现在完成时。如果用的是by now(到现在为止），可以考虑用现在完成时。

Answer 3

C 主语为复数，且happen需主动
D 自从一年以前没见过
C 她妈进她卧室之前已经写好，过去完成时
B 有recent，要用完成时态
C 被嘲笑，laugh是不及物动词
B there be固定格式，且rain不可数
B 过去完成时

Answer 4

C happen是不及物动词。没被动
D since和现在完成时连用
C 过去完成时指用于过去的过去
B In recent years 和现在完成时连用increase rapidly.不及物动词用法
C根据题干要用被动语态
BThere has beenvery little rain.一直雨水少
B by the end of last term和过去完成时连用

Answer 5

A everyday 所以用一般现在时且不是被动发生。 B since加一段时间表示从那以后到现在，不用再加ago C 过去的过去用过去完成时 D 在最近几年持续上升所以选Has been B 被嘲笑 Be laughed A 有雨而不是一直不停的在下雨 D 到学期结束他们学了。。。，现在完成时
