其实这些题有一个规律是很象的,你记住,一个句子里面,除非有and but这些连词连接,否则是不能存在两个动词的（be动词也是哈!）,就象如果有两个孙悟空一起,肯定会打架的!
做老师感觉真好~
(1)He sent me an e-mail,___to get further information.
B hoping
这句话是伴随状语从句.如果中间有一个and,就要用hoped.但这里没有连接词.这时你要看这个动词是主动还是被动,因为是他希望的,所以这里是hoping.如果后面是被动,比如被他妈妈要求给我发邮件,就是 He sent me an e-mail,asked by his mother.
(2)The school library___ from 12:00 to 13:00.
C is open
这句话是由open的词性决定的
open 5.营业的,办公的;出入自由的[F]
Is the store open from 9 to
那家商店是从上午九点营业到晚上七点吗?
当然,如果选项中有opens,也是正确的.
(3)___the houses were flooded after the rain.
B A great many
这是搭配用法A great deal of+不可数
A great many直接跟可数名词
number要用A number of
(4)John saw an old woman___down by a___taxi.
knocked;running
see sb do sth,加原形
但是这里是老人被车撞到
被动语态,所以要用KNOCKED,而run修饰TAXI,我们知道TAXI是跑者的,所以要用RUNNING TAXI
(5)We___the history of France this term.
A are learning
这个学期么,考试的时候你们不是还没放假么,怎么可以选过去式呢?
(6)The murderer's identity remains___.
A unknown B to being unknown C be unknown D being unknown
这是由remain词性决定的,remain后面可以直接加形容词.
remain 4.保持,仍是[L]
This room remains cool all summer.
这个房间整个夏天保持凉爽.
She remained silent all night.
她整个晚上沉默不语.

(7)The river is about seven meters___.
A widely B cross C narrow D across
cross是动词,这里不能用,narrow不可以与河的宽度搭配.widely如果是wide就是正确的.所以剩下的只有across了!
across
2.宽
The river is two miles across.
河宽二英里
