关于英语的题目
能不能帮我指明一下下列题目的语法点,
1 I forget( B )a present last July.
A giving B being given C given D to give
(这题为什么用被动式）
2 It ( A )it is going to snow heavily.
A seems B looks like C looks D looked like
(looks like为什么不能选择）
3 There's something wrong with your leg.You'd better have it further( D ).
A to examine B examing C examine D examined
4 Last night ,at ten o'clock,Jack was heard( B )with his friends.
A to talk B talking C talk D talks
(为什么有些被动式的后面＋ to,而有些却不＋to）
5 ( D )searching for a robber.
A A police is B The police is
C A police has been D The police are
（为什么用are）
6 ( D )of what he said ( )true.
A None,are B None,is C No one is D Nothing is
(None为何不能选）
7 We finally( C )the small town before dark.
A got B arrived C reached D reach at
(get,arrive和reach有什么区别）
8 I'm often late( A )school.But I got up early and did not come late( )school this morning.
A for,to B for,for C to,to D to,for

1 I forget( B )a present last July.
A giving B being given C given D to give
give是一个及物动词,也就是说它的后面必须跟宾语.give后面的间接宾语和直接宾语都不能没有.但是这道题当中,选项包括后面缺少都间接宾语.这个时候就需要考虑是不是被动形式.如果是被动形式的话.就可以解释通了.I做的是forget的间接宾语.这样就明了了.
2 It ( A )it is going to snow heavily.
A seems B looks like C looks D looked like
这个应该说是一个固定用法.这个是从句,句子当中省略了that,即:
It seems (that) it is going to snow heavily.
It seenms that+从句:意思就是看起来好象要.
这个是固定形式..
3 There's something wrong with your leg.You'd better have it further( D ).
A to examine B examing C examine D examined
一般地.have后面可以接下列形式:
have sth done 就是"让别人do with sth".例如:have it repaired让别人修理它.
have sb do 让某人做某事.例如:have Jim do his homework.让Jim做他的作业.
可以明显地看出来.这道题当中.应该是第一种用法.在句子当中further只是一个修饰作用.并不是句子的主干结构.
4 Last night ,at ten o'clock,Jack was heard( B )with his friends.
A to talk B talking C talk D talks
(为什么有些被动式的后面＋ to,而有些却不＋to）
这个是要看原来的句子了.也就是该被动局对应的主动句.然后要根据主动句当中谓语动词来选择.这个给你举个例子你理解一下吧.
He was seen swim in the river once.他曾经被人看到在河里游泳.
原来的主动句当中.Someone saw him swim in the river once.
He is alowed to go out.他被允许出去了.
原来的主动句当中.Someone alows him to go out.
看出来了吧?原来的主动句当中是是v+sb+do的话.那么就不用to,如果是v+sb+to do的话.那么就是to do.
另外还有一点要分清.原来的句子当中是没有to还是to被省略了.如果是被省略了.那么改成被动句的时候就需要把to加上.常见的一个词就是make.make sb to do sth.在主动句中to被省略了.但是改成被动句的时候还要加上.
有一点可以简单粗略地判断是用哪种,如果是曾经做过的.那么用do,如果是正在,那么需要用v-ing,如果是在主句动作发生之后发生的,一般要用to do.例如上面的"他被允许出去了"出去发生在允许后面,这样要用to do .
5 ( D )searching for a robber.
A A police is B The police is
C A police has been D The police are.
the police是一个集合名词,本身就是一个整体,是当成复数看待的.和people是一样的.
6 ( D )of what he said ( )true.
A None,are B None,is C No one is D Nothing is
None是否定三个以上的可数名词用的.这个句子当中的是不可数名词.所以是不能用的.
7 We finally( C )the small town before dark.
A got B arrived C reached D reach at
三者都可以表示"到达"的含义.但是形式不同.
get表示的时候.是get to+n
arrive表示的时候,是arrive in或者arrive at+n
reach表示的时候,直接加名词.reach+n
I'm often late( A )school.But I got up early and did not come late( )school this morning.
A for,to B for,for C to,to D to,for
be late for sth干什么时候迟到.late for有迟到的特定含义.这里late是形容词性.
do sth late这里late是副词.修饰do的.句子当中late to不是一个词组.要把它们断开.写成这样.是故意迷惑我们的.如果换成这样的形式.估计你就明白了:But I got up early and did not come (to)school late this morning.
