1.The sign"@"in reads______(C)
A.a B.to C.at D.on
意思是：“@这个符号在tzjoy@hotmail.com中读什么?” 这个读音就是at ,没什么原因的……
2.--Nancy_____the letter from her mother.
--No,she can't have.The postman hasn't come yet.(选C为什么不是B?)
A.can receive B.can have received C.must have received
这个题考的是情态动词表猜测的用法,肯定猜测可能性从大到小依次用must may might,否定猜测从大到小是can't couldn't ,用的时候就直接用can't或couldn't 所以排除A和B,must/may/might + have done ,是表示对过去的猜测~~
3.They must have been here yesterday,___?(B)
A.mustn't they B.didn't they C.mustn't have they
这个题考的是对情态动词反义疑问句的提问,情态动词出现在前句的时候用do来提问,如果讲的是过去的,就用did~~ 这个记住就行了~~
4.Why do you make me do so?(C)
--I am sorry that you____do such a thing.
A.would B.can C.should D.may
这个题考的还是情态动词的用法,should 在这里表示命令~~ 其实也可以用must ,选项里没有~~~
5.What would have happened_____,as far as the riverbank?(C)
A.if Bod has walked farther
B.if Bob should walk farther
C.had Bob walked farther
D.if Bob walked farther
这个题考的是虚拟语气下的倒装,就是去掉if需要倒装
6.When a pencil is partly in a glass of water,it looks as if_____(C)
A.breaks B.has broken C.were broken D.had been broken
考的还是倒装,as if 意思是这个铅笔放到水里以后,看起来好像是折断了一样,实际是没断,所以要用虚拟,排除A和B,前面用的是一般现在时,所以后面要统一,用虚拟的一般现在时
P.s 感觉是一个卷子上的,考的是情态动词,情态动词一般就是表猜测,表到某种语气,最重要的就是虚拟语气,推荐薄冰语法,我当时用的是魔法什么的,彩页,讲的很简单很容易理解,但都是考点,我把那个书看了几遍,感觉不错,你可以去书店先看看~~ 加油加油~~~

该名网友总共回答了1个问题，此问答他的回答如下：

第一题，@读at是通常的读法，表“在……”
在tzjoy@hotmail.com中，tzjoy为邮箱用户名，hotmail.com表邮箱所在网站（这是MSN的邮箱名），而@相当于prep.，表该用户邮箱所在地址。
第二题，由题意，句意为：-Nancy一定已经收到她妈妈的来信了。
-不，她不可能收到。因为邮递员还没...
