就这么点分,全送了.1>>________,we should choose a name for the paper

1.C according to 根据...按照..
in our opinion 据我们看来
2. B
3.is,因为20minutes 时间.be enough for sb to do sth.
4.repair,mend 区别
mend通常指较简单的修复过程,一般不需要专门技术或特殊工具.
repair可与mend换用,但一般指需要较高的职业技能和使用较复杂的工具进行修理.
"he still can't have it done."翻译为 他仍然没有做完它．
5．if和whether都可译为"是否",二者引导宾语从句时通常可以互相替换,口语中多用if代替whether.例如：Ask if/whether he plans to come to the meeting. 而以下几种情况中, 只能用whether:
1. 强调两方面的选择,特别是句中有or not时.如：
Let me know whether you can come or not.
2. 宾语从句前置时.如：
Whether this is true, I can't say.
3. 引导主语、表语、同位语从句时.如：
Whether the football game will be played depends on the weather. （主语从句）
The question is whether he can do it. （表语从句）
The question whether we should go with them must be decided at once. （同位语从句）
4. 在介词之后作介词的宾语时.如：
I haven't settled the question of whether I'll go back home.
5. 在不定式前与不定式一起组成词组时.如：
Whether to go or stay is still a question.
6. 在discuss, decide 等动词后作宾语时.如：
We discussed whether we should go there by plane.
值得注意的是： if还可以引导条件状语从句,是"假如；如果"之意,而whether可以引导让步状语从句,是"不管；无论" 之意.如：
If you ask him, he will help you.
I shall go, whether you come with me or stay at home.
一、if或whether引导宾语从句时,作“是否”讲,常放在动词ask 、see 、say 、know和find out等后面.一般情况下,两者常可换用,在口语中多用if.如：
例1 Nobody knows whether (if) it will rain tomorrow. 没有人知道明天是否下雨.
例2 Lucy asked whether (if) they had a cotton sweater .露西问他们是否有棉制的羊毛衣.
二、if或whether引导宾语从句时,要注意三个方面,即连词、语序和时态.
1 if或whether不能和that 或其它连词（副词）同时使用,也不能省去.如：
例3 我不知道他今天是否会来.
[误] I don’t know that if(whether) he will come here today .
[正] I don’t know if(whether) he will come here today .
例4他走过来看看猫是否出了毛病.
误] He came to see what if (whether) there was wrong with his cat .
[正] He came to see if (whether) there was wrong with his cat .
2 if或whether引导的宾语从句时,虽具有疑问意义,但从句语序应用陈述句语序.如：
例5 Did you know the way to the hospital ? The old woman asked me .
The old woman asked me .if (whether) I knew the way to the hospital .老妇人问我是否知道去医院的路.
3 if或whether引导的宾语从句应和主句的时态保持一致.即主句为一般现在时,从句用任一种时态；主句为一般过去时,从句则用过去时中的任一种时态.如：
例6 I don’t know if (whether) he has come here . 我不知道他是否来过这儿.
例7 Tom asked if (whether) I had read the book . 汤姆问我是否看过这本书 .
三、if和whether的区别：
1 在动词不定式之前只能用whether .如：
例8 I can’t decide whether to stay. 我不能决定是否留下.
2 在whether …… or not 的固定搭配中.如：
例9 I want to know whether it’s good news or not . 我想知道是否是好消息.
3 在介词后,只能用whether.如：
例10 His father is worried about whether he lose his work . 他的父亲担心是否会失去工作.
4宾语从句放在句首表示强调时,只能用whether .如：
例11 Whether they can finish the work on time is still a problem . 他们是否能准时完成这项工作还是个问题.
5用if会引起歧义时,只用whether.如：
例12 Could you tell me if you know the answer ?
这句话有两种意思：“你能告诉我是否知道答案吗?”或“如果你知道答案,请告诉我,好吗?”.如用whether可避免歧义.
6.>>The govement has spent ___A___money on education.
A. lots of B.quite a few
c. a huge amounts of
因为A后可以接可数名词也可以接不可数名词,B后只能接可数名词,money是不可数名词,所以选A,至于C,lots of 可以加任何形式.
huge amounts of/amount of 不可数名词.
7.>> in one's __fifties__(50) ．
8.open有两个词性——动词和形容词
例如,I want to open the door.我想去开门,open做动词
The door is open.门是开着的.open做形容词.
opened不是形容词,而是open的过去式、过去分词和被动式
例如,The door is opened by me.门是我开的.
做为一个过去分词,opened有时可以做形容词性使用,如an opened door,一扇被打开的门.但在表述门开着的状态的时候,不可把opened用作形容词,而要用open,这是一些人常犯的错误.选open
9.C
a.went off 下车
B.went on 继续
c.went out外出
d.went in （没见过）
10.不是固定词组吧?!
11. a lot of ,quite a few 区别?意思上相同吗?
上面好像有了吧?
12.a little milk
a little肯定,接不可数名词
little否定,接不可数名词
13.The pincake usually taste __well__.
delicious形容词,well副词.taste动词,要用副词修饰.
14.pessimist悲观主义者
15..当用于同级比较时,as .as 既可用于肯定中也可用于否定句中,
而so.as 只能用于否定句中.
2.当表示只要时,两者没有什么区别,可以替换.
