The programme can't be             him because it is beyond his ability.

charged with

in charge of

taken charge of

in the charge of

考查固定短语辨析。句意：这个项目不可能由他负责，因为它超出了他的能力。A. charged with控告；B. in charge of负责，主管；C. taken charge of 接管，负责；D. in the charge of 由......负责。根据because it is beyond his ability及空格后him可知用in the charge of 符合题意。故选D项。

The student completed this experiment to make come true         Professor Joseph had said.

that

what

when

where

考查名词性从句。句意：为了使约瑟夫教授所说的成为现实，这个学生完成了这个实验。        Professor Joseph had said作make的宾语从句，该从句中，空格处在从句中作said的宾语，表示“......所说的话”，因此应用what 引导该从句。故选B项。

It has been warned that        to the surroundings with people infected by Covid-19 without any

protection can lead to severe result.

being exposed

exposed

having exposed

to expose

考查非谓语动词。句意：有人警告称，在没有任何保护措施的情况下，暴露在有感染 Covid-19的人环境中会导致严重的结果。分析句子结构可知expose在句中应用非谓语动词形式，表示“暴露”短语为be exposed to,且从句中缺少主语，expose 与主语people是被动关系，故应用动名词的被动式作主语。故选A项。

It is said that railway station is now         large as What it was.

as twice

twice as

twice much

much twice

考查倍数表达法。句意：据说火车站现在是原来的两倍大。倍数的基本结构一般为“A+倍数+as+形容词或副词的原级+as+B”，表示“A正好是B的多少倍”。联系下文large as，此处用twice as large as 表示“是.....的两倍大”。故选B项。

It was last night ________ I saw the comet.

the time

when

that

which

强调句的结构是：It＋be＋强调部分＋that(who)＋主谓句。强调句的连词只有两个，that和who。当强调的部分是人，且为句子的主语时，才用“who”，其余用that。因此选C。

With a lot of difficult problems           ,he feels like a cat on  hot bricks.

to settle

being settled

settling

settled

考查非谓语动词。句意： 因为有一大堆难题要解决，他感觉像像热锅上的蚂蚁。本句with +名词+to do sth,动词不定式表示的动作尚未发生或当时看来尚未发生。本句表示“因为有一大堆难题要解决”。故选A项。

She reading

She reads

To read

Reading

考查时态以及省略。句意：—Joan正在做什么？—在房间里看报纸。根据句意说明描述的是现在正在发生的事情，所以使用进行时的时态，是对what is Joan doing?的回答。回答完整应该是she is reading...，此处省略了she is，故D正确。

The question of           English will keeping on changing in the future is easy         .

if; to answer

whether; to be answered

if; to be answered

whether; to answer

考查宾语从句和非谓语动词。句意：英语将来是否会继续变化这个问题很容易回答。第一空为宾语从句，从句中不缺少成分，表示“是否”，应用whether，if 引导的宾语从句不能充当介词的宾语，故排除A和C；第二空，这是be +性质形容词+不定式结构，这种结构中形容词说明不定式的特性，句子的主语是不定式的逻辑宾语。故选D项。

The salesman scolded the girl caught         and let her off.

to have stolen

to be stealing

to steal

stealing

考查非谓语动词。句意：这个销售员责备了被抓住正在偷东西的女孩，然后，让她走了。分析句子结构，caught是过去分词作定语，修饰前面的名词 the girl,"女孩"和"偷东西"之间是主动关系，用现在分词作宾语补足语，构成catch sb doing sth结构。意为抓住某人正在做某事。故选D项。
