Tom's teacher and friend ____ coming to Tom's home.为什么不是are而是is?A good idea just ______ me-Let't go swimming.为什么不是struck而是hit?There are two _____ of people waiting outside.为什么是score而不是scores还有讲一下doz
Tom's teacher and friend ____ coming to Tom's home.
为什么不是are而是is?
当两个表示身份的名词共享一个限定词（名词所有格、物主代词、冠词）是意思是一个人同时具有两种身份,应该视作单数.
A good idea has just ______ me-Let't go swimming.（原句中脱掉了has）
为什么不是struck而是hit?
当表示突然想到或发现这个意思时,既可以用strike on也可以用hit,但是原句中没有on,所以不可用struck
There are two _____ of people waiting outside.
为什么是score而不是scores
还有讲一下dozen和dozens的语法
数词dozen,score,hundred,thousand等只有在表示“数十、数百、数千”是才可以用复数,如果只表示具体数目（如上题的四十个）只能用单数,正如there,four不能用复数一样.
The prices of the flats ______ are several times as high as in the countryside.
为什么at downtown而是downtown?
downtown的用法和home一样,如果表示“往市区走、回家”,前面不可用介词；如果表示“在市区、在家里”,就得加上介词at.

全部展开

Tom's teacher and friend 是一个人，这个人既是老师又是朋友，所以用is，如果是Tom's teacher and his friend，那么应该用are
hit不仅有打之类的意思，在口语中，还意为，被...想起。用在此句中很合适。
空格后面有me，故这时strike是及物动词，stick的及物动词释义
strike
及物动词 vt.
1.打,击,攻击[O1]
2.(用爪)抓伤;(用毒牙)咬伤;(疾病)侵袭
3.(钟)敲响报(时)
4.(船)触(礁);(光)照在;(声音)传到
5.打(火);划(火柴);盖(章)
6.铸;打出;压出
7.删掉;取消[H][O][(+off/out/through)]
8.达成(协议),签订(合同等);结算(收支)
9.打动,感动,给...以印象[(+as)]
10.拆除;拔(营);降下(旗,帆等)
11.把...刺入;使穿透;使深入[O][(+into)]
12.扎(根)
13.到达,来到;沿...走
14.遇见,邂逅;偶然发现
15.取...姿态,装出
16.弹奏;奏出
17.使突然想起[W]
18.使处于特定状态[H][O8]
都不符合句义
dozen 一打，十二个,score 二十，都是单复数相同的计数单位。所以用dozen。
dozens组成词组Dozens of，表示大量的。例如，Dozens of journalists laid siege to his flat.
大量记者把他的公寓围住了
downtown 形容词性质，意味(市中)商业区(的), 闹区(的)，形容词修饰flats，不需要at
