Let's learn to use the problem we are facing         a stepping-stone to future success.

to

for

as

by

考查介词词义辨析。句意：让我们学会把我们所面对的问题作为通向未来成功的手段来利用。A.to朝，对 ；B.for 为了，对于；C.as 作为；D.by通过，凭借。根据句意可知，此处“作为”符合语境。故选C项。

---Have you moved into        new office?

---No, the building is under          construction.

a; the

the; /

/; the

/; /

考查冠词。--你搬到新办公室了吗？--没有，大楼正在建设中。new office 谈话的双方都知道，所以是特指，需要用定冠词the,第二句under construction 指“正在建设中”，是固定搭配。故选B项。

We played well, but I felt the team were            by one member, who didn’t try his best on the court.

let down

turned down

picked up

cheered up

考查动词短语辨析。句意：我们打得很好，但我觉得有一个队员在场上没有尽最大努力，让整个球队失望了。A. let down 使失望，放下；B. turned down 拒绝，调小；C. picked up捡起，接；D. cheered up使兴奋，振奋。结合句意可知，“有一个队员在场上没有尽最大努力”，所以“我们”感到失望。故选A项。

Every evening after dinner, if not ________ from work, I will spend some time walking my dog.

being tired

tiring

tired

to be tired

考查省略句。当状语从句的主语和主句主语一致，且状语从句中有be动词的时候，可以把状语从句的主语和be动词一起省略，本题if后面省略了I am，句意：每天晚上吃完晚饭以后，如果不是很累，我就会花点时间来遛狗。故C正确。

I found _____ convenient to shop online at home .

it’s 

that

it

that was

考查强调句。句意：我发现在家网购很方便。这里it指代后面的to shop online。其中的强调句式是：主语+find it +形容词+to do，意为主语发现做某事是...的，故选C。

"Society" is a(n)              term;it may mean much or nothing.

autonomous

ambiguous

fragrant

fragile

考查形容词词义辨析。句意：“社会”是一个模棱两可的词；它可能意味着很多，也可能没有意义。autonmous 自治的；ambiguous模棱两可的；fragrant芳香的；fragile脆弱的。结合后文it may mean much or nothing可知，空格处填ambiguous模棱两可的。故选B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。
