1,这个句子中,前面的状语部分.
表示原因"出于".不定式一般用来表示目的性的原因，即这个原因将要实现．而动名词则表示伴随性的原因．
可以理解：
To be a good student, he studyed very hard.
想成为一个好学生，他学习很努力
Being a good student, he studyed very hard.
作为一个好学生，他学习很努力．
本句中的害怕，是一种感觉，不能是目的性的，只能是伴随性的．
2，no one ____ that to his face
A.dare to say B.dare says C.dares saying D.dear say
Dare 是一个特别的动词．可作为情态动词．和can 一样，比need的级别高，使用比need更灵活．
How dare you do that? 你怎么敢那样干？
Dare you hit me! 你竟敢打我！
第二句中的Dare，就是情态动词前置．这个意义上，need是不可以前置的．而can will would等可以．
3，he makes a____by painting.
A.living B.life C.livings D.lives
make a living固定用法．
谋生make a living
谋生earn a living
谋生make one's living
谋生earn one's living
〔Google〕to make a living; to gain a living; to earn a living;
living 作为名词为生计，生活。为可数名词，和life(生命)一样。一人一个living/life
4，mary feels lonely and she needs a friend____
A.play Bto play C.playing with D.to play with
to play with 作为friend的不定式定语，作为主词的friend是和She一起玩的。
请体会：
a friend to play with 一个一起玩的朋友。
a friend to play 一个玩弄的朋友。
a piano to play 一架演奏的钢琴。
a friend to love 一个去爱的朋友
a friend to make love with一个作爱的朋友
a friend to talk with 一个诉说的朋友
a friend to talk about一个可以谈论的朋友
5，with____,john really didn't know what to do
A.all these mouths to feed B.feeding all these mouths C.all these mouths feeding D.all these mouths feed
答案为A。with all these mouths to feed
但是，A和B在语法没有错误。C和D在语法上错误。
有这么多张嘴要喂，john真不知道怎么做了。
with all these mouths to feed,中，to feed 为不定式定语，用来说明all these mouths.
with feending all these mouths.随着喂这些嘴巴之意，与本题不合。但是在下面的句子是有效的：
with feeding all these mouths, John felt very tired。随着喂这些嘴巴，john觉得很累。
C和D中，feed不能是mouth的宾语。
6。each of us was interested in the way in____she expressed her idea
A.which B.that C.what D.how
答案为A。
that前一般不加介词。
在下句中则which 和that都是正确的（in放在最后）：
Each of us was interested in the way (that／which) she expressed her idea in.
7,____is where she gets all her money from
A.what i cannot understand it B.that i cannot understand C.what i cannot understand D.which i cannot understand it
这题我感觉是选B i cannot understand是完整的句子所以陈述句做主语前面加that 而这题答案为什么是A?
这题的答案正确的是A。
一般地认为：“understand 后只能跟一个宾语。不能双宾语”。您所说的也是这个原因。
但是这样以来，本题中的B,C都正确了。那么你要选B还是C呢？
实际上，understand 正是一个双宾语动词。注意下面的分析。
“Some thoughts, such as "want"/"need", "know", "understand", etc. can be expressed in Thamil only using the dative case and a certain set of verbs. Sentences that use these verbs will be a little different from the sentences we have seen so far. The way the verbs are used will be different, and some verbs have certain peculiarities.”

8，i wish they___in their ball game
A.will be succeeded B.succeeded C.would be successful D.were success
此题的正确答案为B。
英语和汉语、一样，有许多不同的用法。所以作选择题要排除一下，并不只是一种想当然的答案。
●关于D。因为success作名词或动词。所以D错误。
●关于C。sucessful 作为成功的这一意思时，一般指事件，而不指人。
●关于A。succeed为动词成功，A中用了被动式，错误。
●在B中：主动式，但为过去时态。指球赛已经过去。我希望他们（昨晚）比赛赢了。
下面为经典的一句：
I wish they succeeded in court to get ALL of their land back。
请在google中搜索 "wish they succeeded"（连引号一起搜），你将有新的发现。英语有窃门哈～～
而你搜 "wish they would be successful"（连引号一起搜），只能搜到一个结果。
