Someone is knocking at the door _it be vera?
No,it_be her.she left for New yourk this morning
A can t musn t B Might can t C May doesn t D Can can t
2 The students_go home until their homework_
A won t will be done Bdon t will finish Cwon t is finished D didn t finished
3 There is__snow and it s__cold this winter
(用too much 和much too 填空)
4 NO one told us__we need your help
A how to do it B what to do C how should we do D what should we do
5 The little boy__by the big one this morning
Awas made to try Bwas made cry C made to cry D made cry
6 Up to now all the money
A has been run out B has run out C has used up D have been used up
1.D
翻译:--有人在敲门.会是薇拉吗?--不,不可能是她.她今早去纽约了.
第一空填can't的话,句意肯定不通,排除A;
而may/might表示“可能”时,一般不用在疑问句/否定句中,排除BC.
表示“不可能”只用can't,所以答案只能是D.
2.C
until从句中,主语their homework和finish之间明显是被动关系,排除主动结构的BD;
如果选A,则不符合状语从句时态的“主将从现”原则,即主句可以用won't即将来时,但是until从句必须使用一般现在时,而不能使用一般将来时will be done,排除A.
3.too much,much too
too much = much,意思是“许多”,用来修饰不可数名词snow;
much too = too,意思是“太/非常/很”,用来修饰形容词/副词(cold),表示程度.
4.A/B都可以.
如果使用宾语从句,则必须使用“疑问词what/should + 陈述句”结构,但是CD都是should we,并不是陈述句序,排除;
AB都可以,因为how做do it的方式状语,而what可做do的宾语,这两个答案都使用了“疑问词 +不定式”结构,充当told的宾语.
我怀疑是楼主打错了.如果A是how to do,则选B;同样B是what to do it,则选A.
5.A
翻译:这个小男孩今早被一个大男孩给弄哭了.
很明显,句子主语the little boy和使役动词make之间为被动关系,排除主动结构CD;
主动结构为made the little boy cry,即使用不带to的不定式即动词原形cry做宾语补足语.
但是在被动句中,不定式必须补上to,所以答案是was made to cry,排除B.
6.B
主语all the money为不可数名词,所以谓语动词必须用单数,排除D;
use up是及物动词短语,必须加all the money做宾语.反过来,则all the money和use up为被动关系,排除使用主动结构的C;
但是run out是不及物动词短语,all the money和run out之间为主动关系,排除被动结构的A.
如果是run out of,则all the money和run out of之间为被动关系,所以另外一个答案可以是:has been run out of或has been used up.
