Subjunctive Mood
一,语法点归纳
We learnt subjunctive mood last two weeks. There are two forms of the subjunctive : be-subjunctive and were-subjunctive. The be-subjunctive is realized by the base form of the verb. The were-subjunctive has only one form were. In addition to the be-subjunctive and the were-subjunctive , we can use past tense forms of verbs an past tense modals for the same prupose.

8,Q:Firms that use computers have found that the number of staff ____ quality control can be substantially reduced.
9,Q:____ at in this way, the present economic situation doesn’t seem so gloomy.
10,Q:She did her work ____ her manager had instructed.
11, Americans eat __A__ as they actually need every day.
A. twice as much
protein
C. twice protein as
much
解:考查倍数的表达。根据规则,运用统计比较as…as…,表示倍数的词置于第一个as之前,比较的性质与对象谓语两as之间,因此A符合要求。
12, Until then, his family __D__ from him for six months.
A. didn’t
hear
解:考查过去完成时。根据Until then可以看出主句的行为发生在该时间前,再由表达一段时间的for six months可以断定此处应用过去完成时,所以是D。
13, There ought to be less anxiety over the perceived risk of mountain climbing than __A__ in the public mind today.
A.
exists
解析:本题考查than引导的比较状语从句的用法。
14, He’s __C__ as a “bellyacher”—he’s always complaining about something.
A. who is
known
解析:what 可作关系代词,表示“···的事物或人”,而who,whom,which都没有此种用法。What在此处构成what is known as ···,表示“所谓···的”,做句子的表语。
15, I went there in 1984, and that was the only occasion when I __C__ the journey in exactly two days.
A. must
make
解析:本题表示:1984年我去过那儿,那是仅有的一次,我用了足足两天的时间终于完成旅程。A和B的语气与题意不符,be able to与could一般情况下课通用,但当表示“经过努力或克服了困难之后做成了某事”时只能用be able to,所以用C。
16, The Clarks haven’t decided yet which hotel __C__.
A. to
stay
解析:不定式前可以加疑问词作句子成分。另外stay是不及物动词,必须加at才能接hotel.
17, He __A__ unwisely, but he was at least trying to do something helpful.
A. may have
acted
解析:本题考查情态动词+动词的完成时的用法。根据题意排除C和D,A表示不太肯定的推测,而B表示肯定的推测,符合题意。
18, Come and see me whenever __C__.
A. you are
convenient
C. it is convenient to
you
解析:whatever引导的时间状语从句须用一般现在时表将来,因此先排除B和D,另外,convenient一般不用人来作主语,而是常构成be convenient to/for sb.结构,所以选C。
19, You __A__ Mark anything. It was none of his business.
A. needn’t have
told
解析:needn’t have done的意思是“做了本没有必要做的事”。
20, He __A__ the 8:20 bus because he didn’t leave home till 8:25.
A. couldn’t have
caught
C. shouldn’t have
caught
解析:couldn’t have +过去分词,表示对过去已经发生的事实的一种否定猜测,意思是“不可能做了某事”,符合题意。
