15.Their survey will explain to you how what you have observed can be uesd in other fields.

1.Painting in （oils) is one of their spare-time activities.
为什么用oils
answer:oils 在此处不是指石油,而是“油画颜料”的意思,颜料是可数名词.而后面的is 的主语是“刷不同颜料这件事”是单数.
2.a great deal 是怎么用的 后面能跟什么
answer:a great deal 后面跟不可数名词,表示“大量的”例如：a great deal of time
a great deal与great deal of的区别 great many与a great many 的区别
answer:a great deal 可以单独使用,也可以用在形容词或副词的比较级前,表示“大量；许多”；而a great deal of只能用在不可数名词前,表示“大量的”.如：We learned a great deal from them.我们从他们那里学到很多东西.
"a great many" 与"a great many of" 区别同上,只不过它们后面跟可数名词.
3.The large houses are being painted ,but (at a great expense)
有四个选项 哪里错了
A.of great expense B.in a lot of expenses
C.at a great expense D.by high expense
answer:"at a great expense 以巨大费用" 固定搭配,其实"at+名词"的短语会含有一定的"以.为代价"意思在里面.其他几个说得都不通的.你可以读读试试,"in+名词"常表示"用什麽方法,手段等"
4.Jim was late for two classes this morning.He said that he forgot both of the (room number).
为什么是room number 而不是room's number
answer:带所有格基本都是有生命力的人或物,room 没有生命的,其实这里room number 指的是房间号码,中文里有好像有“的,房间的号码”其实号码不是房间的.这里是定语指“房间的号码,而不是别的号码”
5.一系列名词中间的连接 .-.
⑴He invited all of his (comrades-in-arm) to join his wedding party.
⑵After ten years ,all these youngsters became (grown-ups).
⑶The police investigated those (stander-bys)about the accident
⑷The Nazi kept those (prisoners-of-wars)in their concentration camp.
这四个都是有关这一类的 而每四个答案中【s】都出现在不同的单词后面
做这一类题时有些什么规律
answer:这些叫合成名词.它们的复数变化是:在名词后加S,如:comrades-in-arm如果没有名词的话,就直接在后面加S,如:grown-ups.
6.The manager was greatly appreciating that (news reel) made by Linda lately.
A.new reel B.news reel C.new-reels D.news reels
为什么选B
answer:news 指“新闻”不是new--新的,news reel--新闻胶片
不选D 因为前面有“that"
7.All the people at the conference are (mathematics teachers)
A.mathematic teachers B.mathematics teachers C.mathematics teacher D.mathematic's teachers
为什么选B
answer:mathematic 是"数学的",而这里是指"数学学科"用"mathematics" teachers 因为前面是are.
8.(Warned) against the coming hurricane,they dared not leave home.
A.Warned B.Having warned C.To warn D.Warn
为什么选A
answer:这里是分词独立结构做状语从句,其主语是后面的"they" 你可以试著把"they"加到个选项前面就知道哪些是说不通的了.
9.In English-speaking countries,you can't always make yourself (understood) by speaking English.
为什么【understood】在这里用过去式
answer:像yourself 这种反身代词后面都是被动形式.所以是understood.
10.Their plan (proved)to be a perfect one.这里不能用被动语态吗【was proved】
answer:这个句子你需要分清楚谓语是"be" ,前面的"to"是和proved在一起的.
所以不能是was proved,其实这里proved 是过去分词修饰plan.(过去分词是有被动意思,指plan 被提供的.
11.It promises another fine day tomorrow.翻译一下
answer:明天会是一个好天气.
12.They (little) thought that the truth would be finally discovered.
A.little B.not C.small D.bit 选A 的原因
answer:small 和bit 基本上不能修饰thought,not 不能单独修饰thought 要用“don't" "little"表示"一点点都没有"
13.They hardly believe that the apartment which costs them $4,000 is (so small).
A.so small B.such little C.so little D.such small
为什么选A
answer:搞清楚so 和such 用法,so +adj+n.such +a/an +n.such 后面不能直接跟adj.
14.If a claim is kept (alive),it is more likely to be recognized.
A.live B.lived C.alive D.living
answer:这里是要表达："还活著",其他几个词加上去用法都错误.
15.Their survey will explain to you how what you have observed can be uesd in other fields.翻译一下
answer:翻译的时候注意把句子分开,如这句有“what you have observed"--"你观察到的”“how+从句+can be used in other fields"---"你（观察到的）怎样被使用在其他领域”再和上前面的主句“their survey will explain to you"---"他们的调查解释给你" 合起来就是---"他们的调查可以解释你的观察能在其他领域被使用.
