英语语法问题

they were the first men to land on the moon.请问这句话能否写成they were the first men landing on the moon.

不可以,这里必须用动词不定式,而不能用动词的ing形式。
或许你可以把后面理解成一个定语从句的省略形式(定语部分),这样理解的话好像这么改就对了,实际上是不可以的。至于原因嘛,没有什么原因,这就是一个固定结构:主语+序数词+名次+动词不定式(不能改成动词的ing形式)

这是个常考点,也是个易错点,一定要牢记呀
希望对您有所帮助

可以,但一般不用,
”the first...to do sth 第一个/批做某事的“ 用得比较多!

1、As 就是关系代词,指代后面的句子honesty is the bestpolicy。

2、As an oldsaying goes 是前置的非限制性定语从句,其结构如下:

主语:an old saying
谓语动词:goes【此处的 go 是及物动词,相当于 say 的意思】
宾语:as

3、As 也可以用下面宾语从句代替来理解:

An old saying goes that "honesty is the best policy".(= An old saying says that"honesty is the best policy")

4、As指代后面要提到的或前面已经提到的一个句子,用来引导的定语从句,在从句中充当宾语、主语或表语。另如:

As you can see, we're still working. 如你所见,我们仍在工作。【as 指代 we're stillworking,在从句中作宾语,等于含有宾语从句的 you can see that we're still working 所表述的意思】
We were sitting, as I remember, in a riverside restaurant. 我记得我们当时是坐在一个河畔的餐馆里。【= as 指代 we were sitting in a riverside restaurant,在从句中作宾语,等于含有宾语从句的I remember that we were sitting in a riverside restaurant 所表述的意思】
The statement reads in full as follows: … 声明全文如下:…… 【as 指代 the statementreads in full,在从句中做主语,等于含有主语从句的 That the statement reads in full follows … (全文) 所表述的意思】
We're busy enough as it is. 我们实际上很忙。【as 指代we're busy enough,在从句中作表语,等于含有表语从句的 It is that we're busy enough 所表述的意思】

不能。可以改成they were the first men landed on the moon. 这是一个定语从句,前面时态是一般过去时,后面要一致,不是进行时态
