我来给你解释吧.
1.-This is no-smoking zone.Can't you see the sign?
-sorry.I( )it
A.haven't seen B.won't see C.don't see D.didn't
翻译：这是无烟区.你没看见那个标志吗?抱歉,我刚刚没看见.
作者回答时说我没看见,他是在什么时候没看见呢?在回答之前,即刚才没看见,很显然,是一般过去时.所以选D
2.Dad,let us,( )go to the cinema,( )?
A.Jake and I, shall we B.Jake and me, shall we
C.Jake and I,will you D.Jake and me,will you
翻译：爸爸,让杰克和我去电影院好吗?
首先第一空,ME是个宾格,此处不能用,只能用代词,I.而shall we 和 will you 区别如下.如果用前者,则表示除了JACK和I,爸爸也得去.而后者表示征求爸爸的同意,而去电影院的只有JACK和我.很显然,爸爸不去.所以选C.
3.-Why can't I swim in the lake,Daddy?
-You will be ( )The water is freexing cold
A.sorry B.afraid C.anxious D.unpleasant
翻译：爸爸为什么我不能在湖里游泳呢?你会不舒服的,这水冰冷.
此题根据意思来选.A 抱歉.B 害怕 .C 焦虑.D不舒服,不愉快.选D
4.Tom's mom kept telling him that he should work harder,but( )didn't help
A.he B. which C. that D.it
翻译：妈妈一直告诉他要努力工作,但是这并没效果.
“这”指代前面整个句子,而可以指代句子的只有“that”,所以选C
5.In the dark street,there wasn't a single person( )she could turn for help
A.to whom B.who C.from whom D.that
翻译：在这里漆黑的街道里,没有一个单独的行人可以让她求助.
固定搭配 turn to sb for help 所以选A.
6.-Could you tell me who invented()telephone?
-()Scotch scientist named()Alexander Graham Bell
A./,A,/ B.a,The,/ C.the,A,/ D./,A,an
翻译：你能告诉我是谁发明了电话吗?是一位叫贝尔的苏格兰科学家发明的.
第一空,表示一类东西,前要用THE,第二空,一位苏格兰科学家,泛指,用A,第三空,某人名字前用零冠词,所以不加,所以选C.
7.My dictionary ( ).I have looked for it everywhere,but still( )it.
A.has lost,don't find B.is missing,didn't find
C.has lost,haven't found D.is missing,haven't found
翻译：我的字典丢了,我找了每个地方,但到现在为止还没找到.
第一空表示此字典现在处与丢失的状态,用ing 表示,第二空 表示还未找到,表示迄今为止还没找到,表示对现在的影响,所以用现在完成时,所以选D.
8.( )are the days when teachers were looked down upon.
A.Gone B.Go C.To go D.Going
翻译：那些老师被瞧不起的日子一去不复返了.
日子逝去,用The days are gone.只是此处倒装,把GONE提前了.所以选A
9.On my way home ,I saw a thief ( )money from a lady by the police.
A.being caught stealing B.having caught stealing C.caught stealing D.be caught stealing
翻译：在我回家的路上,看到一个贼偷一个女士的钱时被抓住了.
固定搭配：感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel + do 表示动作的完整性,真实性；+doing 表示动作的连续性,进行性,所以此处+doing ,表示进行性.而catch后+doing ,属于固定搭配.所以选A.还有注意被动语态,所以排除B.
0.If these trousers are too short,buy a somewhat bigger( ).
A.set B.one C.ones D.pair
翻译：如果这些裤子太短,买一些长点儿的.
因为前文提到these trousers ,所以后面比较级要求用同形式,也应该用复数,所以选C,表示复数,D,a pair of trousers表示“一条裤子.”
11.Mary was a doctor and she could write poems.So ( )Tom.
A.was B.could C.it was with D.it was
翻译：玛丽是一个医生并且会写诗.汤姆也一样.
这个题选C.当前一句的主句出现两个谓语时,后面表示某人也一样时,要用
so it is/was with sb.所以选C.
希望可以帮到你.我觉得我的答案应该比较正确吧.
