1、D.impress作为不及物动词时,与on/upon形成固定搭配,在被动语态下,表现形式为be impressed on/upon.
2、答案也有错的时候吧.不选D吗?
3、have been doing sth是一个相对较复杂的时态,现在完成进行时,表示过去发生的,现在还没结束,而且将继续进行下去的动作,比较符合思考topic这件事儿的语境,我想了（过去发生了）,但没决定（没结束）,还得想啊（继续进行）.
4、如果选D,那么在第二个分句she之前,肯定要加一个连接词,and,so等等,是选B,但是我说不出为什么.不好意思.
5、我也会选A的.——!
6.、if any 是”要是...”的意思,就是表示假设,比如please give me some milk,if any.请给我点牛奶,要是有的话．那么if any,please indicate可以理解为”如需要,敬请指明”之类的意思．
if ever ,即便有的话也是不多的.if not,如果不这样,不然.if much我也没见过.所以选if ever
7、A.这类句式.和第四题异曲同工吧.
8、B.电源故障,断电.固定搭配.孩子,等上了大学,看多了美剧,你就有语感了.
9、directed是受指示的,expected是所期望的.病人遵医嘱服药,应该是接受指导,是比较严格和严肃的事,而“希望,期望”的语气有些绵软了.
10、B.四个词都有联系,通道的意思,但make connection to是固定搭配.你可以翻译成不要招惹陌生人.
11、take in 1.接受,吸收,接纳；理解,领会；欺骗；包括 2.动词词组 3.收留;使…上当；欺骗；领会；明白；包容；容纳；订阅(报刊) 4.把（某人）带进；领入 ；欺骗
take up 1.占去,占据;开始从事;拿起,接收 2.拿起；着手处理；占去 3.开始(学习或某种爱好)；从事；提出；接受;占(时间,空间等)；拿起；接纳(乘客等) 4.着手； 占有（时间, 空间） 5.占去,占据（时间、地位等） 6.接纳,吸收
make up 1.印构成,组成；(为…)化妆；补充,补足；和解,重归于好；捏造,临时编造,虚 2.拼凑；组成；补偿;捏造,临时编造,虚高；化装；和解 3.构成,拼凑；弥补,赔偿；化装 4.弥补；赔偿；编造；组成；虚构 5.化妆；配制；调制；整
put up 1.建造,支起,搭起；张贴；进行(抵抗等)；提供,提名,提出；提高(价格、速度)；为…提供食宿,投宿 2.举起；盖起；支起；张贴；投宿 3.建起；支起；张贴,挂；修建；留宿；提出 4.建立 put-up 1.密谋的
明显选A.
12、A.on the second thought是思虑再三的意思,固定搭配,没有on a second 的说法.再试一次,不管是第几次,都用a.我能记得的就是这样.毕竟高中毕业六七年了.
很多固定搭配要记住,平时多看英文原声电影电视,增强语感.
看到LZ的题,想起当年高考,英语还不错,便就好为人师了一下,有些问题不知怎么解释,全凭语感,请见谅了.问老师,ta肯定能回答你,再不行就查语法书.
如果有错,还请LZ和LX不吝更正,并海涵.
