两道英语选择题求问

The room (measuring) 10 meters across is large enough for a single man to live in.

答:measuring 10 meters across 是后置定语相当于定语从句which measures 10 meters across

measure这个词和weigh 类似,属于系动词,可以用be动词替换,如:

[Ln] show a certain measure when put on scales, etc 测出重量

She weighs 60 kilos. 她体重为60公斤.

How

much do you weigh? ie How heavy are you? 你体重多少?

This piece of meat weighs four pounds. 这 块肉重四磅.

measure:

[In/pr] be (a certain size, length, volume, etc) 为(某体积、 长度、

容积等)

The room measures 10 metres across.

这房间宽10米.

(注:《牛津双解》这里可能标注不当了,是小写的L)

因为是系动词,所以没有被动语态。用分词则用现在分词(并不表示正在进行)。

Great changes have taken place in that school; it's no longer (what) it was 20 years ago,(when)it was so poorly equipped.

告诉我为什么要用括号里的单词的形式 求详细解答

答:第一空填的是连接代词what, what-从句是名词性从句,在这里作It is的表语,叫表语从句。

what it was 20 years ago. 中的what 引导从句,在从句中作was的表语。

连接代词what相当于一个名词+that-定语从句。当说话者不知道用什么名词或不想明说这个名词时,常用what. Sth. is no longer what it was n years ago.= Sth. is no longer the +名词 +it was n years ago. 某物(现在)不再是它N年以前的那个样子。

本题句翻译:

那所学校发生了巨大的变化。它不再是20年前的那个样子。

第二空的when是关系副词,引导一个非限制性定语从句,when 意为“在那个时候”,也就是说:当时,该校的教学设施很差。
