几道题基本上是关于定冠词和不定冠词的用法的.定冠词是特指,所谓特指,可以这样理譬如说,所谈论的东西可以具体定位到某一人或某一物身上,也就是说说话者指向哪个人或物很明确,是某个特定的人或物,而听者呢,也知道具体该人或该物是谁.不定冠词则没有特指,譬如说a boy, 并不知道说的是谁,the boy, 则可以知道说的是谁（具体是谁要根据上下文就能确定）.下面逐道题分 第一题,看见了不明飞行物,不可能知道看见的一定是哪一个,就像看见了一只鸟,又不知道那一只鸟,只能是不确定,因此用a,要是说昨天出现的那个ufo,今天飞出来又被你看到了,也就是昨天今天的是同一个,那你今天再看见,也确定是昨天那个,才可以用the.
___old man under __tree is over 90 years old .
1 an the 2 the a 3 the the 4 an / 3
under the tree 不是固定用法. 但是你看,说道树下的那个老人90多岁了,你理解下,当别人给你这样说中文的时候,你是不是有这样一种感觉或可以理解这样一种场景,说的那个老人你也能看到,你知道是哪个老人,并且在哪棵树下.也就是说,你们俩个人（说者和听者）,你们俩个人知道你们在说的是哪个老人,哪个树,这就叫特指了.
We haven’t seen you for a few days .
I fell off __ bike an stayed in __ bed for___rest.
1 the / a 2 a the / 3 / / / 4 the / / 1
第一个是用the, 你自己骑车掉下来,那个车肯定是自己身下的那辆车吧,很确定吧,所以特指.stay in bed是固定用法,卧病在床.for a rest 也是固定用法,休息
__ twenty minutes enough for you to finish the work?
1 Are 2 Is 2
20分钟虽然听上去像复数,但是具体问题要具体分析.像是距离和时间有这样一种用法,就是说可以看做一个整体,是一个抽象的概念,是说20分钟够做作业不.是把20分钟看做一个度量单位,此时不可简单地理解成为一般地复述概念,要理解成为单数.距离也是如此.
Two fifths of the land in that district ___covered with tree and grass.
1 is 2 are 1
分数的这种题具体还不是看分数的大小,而是看分数所跟的名词,如果是可数名词,那这道题肯定用复数,因为2/5,也就是40%的什么东西,是复数的,肯定超过一个了.但是如果所说的是不可数名词,不管是百分之多少,它还是不可数的.land 在此时不可数.百分数的用法也如此.
Do you have enough students to the Laboratory?
No ,I think we need __ students.
1 another 2 two others 3 more two 4 two more 4
这就是固定用法.想用数字,再用more. 表示之前已经有了,再来一些的概念.譬如：你还要吃面包不?--Yes, I'd like some more bread. 好的,再来点.（意思就是已经吃了,但还接着吃点）.还有some more water 等等 some 换成数字one, two ,three也是一样的用法,就是具体指再来几个而已.
__ books must be prouced for children.
1 Many thousand 2 Many thousands of
(不是说thousands of 前不能用many修饰的吗?)
其实可以.（而且你可以排除法,1肯定是不对的.）
There are only __ days in February .
1 twenty-eight 2 twenty-nine 1
这道题考察常识,二月份几天.跟英语所有知识点都无关.这道题就算了吧,无需讲解.
Can you finish your composition and hand it in before __?
I will try my best .
1 twenty to nine 2 twenty five past nine 1
(是因为2中少了个字符‘-’吗)
你这可能是中学的题,你要明白,其实中学的题,有些题出得不见得是对的.只不过是在我们当时那个年纪所学的知识来看,它是合理的,但是等你将来接触更多,你会发现,曾经老师所说的错的,其实外国人也都是那样用的.这仅仅是应试的需求,也就说在你们那个阶段,你就按照你们老师说的做题就可以.等你以后长大了,你会发现,这两个都对.现在呢,就选1吧,这就叫应试.
