Answer 1

1.解释:这道题的答案是个定语从句部分.定语从句中的the experts believed可看着插入语,这里可不要.整个定语从句可写成:which/that would affect the work of the brain.并且which/that 作主语,不可省略.由此可见,可能性A或B了.如果要想B对,只有去掉were believed.
2. 解释:本题是考察情态动词表达可能性的的用法.表示可能性用法情态动词有:must,should,can,could,may ,might .其否定形式只有cannot/couldnot.不可能.
他们后加动词原形表示现在或将来;加have dong/been表示完成或过去的可能性.所以,本局句的答案应是B.A短语表达形式不对.must 表可能性不用于否定.如是must have dong,意思是"一定做过".。3
解释:答案可能是D.其意思是"总之"
4 解释: 答案A(暂时). B.在任何时候都不,立刻;再过一会儿(多与将来时连用); D. 任何时候
5 解释:答案可能是B.因为本句的necessary for success是后置定语,相当于which are necessary for success.
结构: It's necessary for sb/sth to do sth.

Answer 2

1. believe后面要加宾语从句，只有believe that的结构，而没有sth. be believed that 的结构，除非是It is believed that...这可以看成一种用法习惯，所以B是不对的。
2. B 意思是，你不可能看到他，因为它跟我一起去了一个国际展览。
can't have done是must have done 的否定形式，都是表示推测的。
而mustn't have done 不是一个固定的用法，很少出现，用于虚拟语气表示“不应该做……”时可能使用，但是也多用shouldn't,很少用这个。
3.D 意思是：说了这么多，总之……
这里的句意是：这里的宾馆条件好，天气也好，沙滩也很美，总之这次旅行棒极了！
而C意思是“事实上，实际上”；
4.A 意思是：马上，就这一刻。
句意：我这会儿找不到，但我过会儿就能还给你。
A这一刻；B 无时无刻 C ＝right now马上 D 任何时间（都行）
5.B
for 的意思是“对于/为了”，意思是：因为他有成功所需的一切品质。
to “对”， by “经由、通过”； on一般指在……基础上
这里的意思显然是“对于成功”

Answer 4

1.the experts believed是插入语，在分析句子成分时可以忽略不计。这样定语从句就是which would affect the work of the brain。很明显，which在从句中作主语。
关于B项。
that were believed would affect the work of the brain这个定语从句中出现了两个谓语（were believed ）和（would affect ），这在英语中是不合语法的。要改可以改成that were believed to have the possibility of affecting the work of the brain。不过这样意思有点区别。

2.选B。
“你昨天不可能见到他，因为我跟他去参加一个国际会议了。”
情态动词+现在完成时，表示对过去的推测，或“过去本（不）应该/必/能…做某事”。
A项mustn't语气太强硬，表示“曾经做过某事，而这是绝对不允许的”；
C项不是对过去的推测；
D项表示“本不必见到他”，不合题意。

3.选D。这是对前面三句话的总结。

4.选A。
for the moment 目前、现在、暂时
at no moment 任何时候都不
in a moment 立刻、马上、一会儿
at any moment 随时、任何时候

5.选B。
be necessary for sb/sth
be necessary to do sth
be necessary for sb to do sth
都是固定搭配。

Answer 5

1.如果选B，就出现了两个谓语动词直接放在一起的现象，即 were believed 和would affect。
改为In the survey they listed twelve kinds of food that were believed to be likely to affect the work of the brain或者去掉were believed，但这样句意会发生改变。
2.选B （其实个人觉得couldn’t have seen更恰当，毕竟是过去时）表示不可能在过去做了某事
must not 表示禁止，一般不予have done搭配
3.选D 意思是总的来说。这有个例句;Altogether their efforts were successful.(总的来说，他们的尝试取得了成功。）
翻译：旅馆舒适，天气温暖宜人，沙滩又美，总的来说这是次非常美妙的渡假。
4.选A
A：暂时；目前
B：没有这个短语，只有at no time意思是在任何时候都不，决不
C立即，立刻；一会儿
D：在任何时候；随时
5.选B。这是necessary的习惯搭配：be necessary for sb/sth
