Three million tons of coal ___ exploited every year.A is B are

Three

million

tons

of

coal

__are_

exploited

every

year.

每年大约有3百万吨煤炭被开采。

我要说从句子主干分析是错误的哦,先说错误的方法。

从句子主干,three

million

tons

of

修饰coal

,因此主语主干是coal

every

year

是补足语

因此

句子主干是

coal

is

exploited

答案是A。

如果你这么想你就大错特错了。

正规的方法应是理解它的意思,并知道考察的是什么知识点。

要明白coal是不可数名词,同样的词还有water,milk,advice,wine等等

但如果用可数量词来修饰如

two

bottles

of

water(2瓶水),five

cups

of

milk(5杯奶),3

pieces

of

advice(3条建议),则就变成可数了。因此答案是B

are

课本常见例句:There

are

two

bottles

of

water

at

the

store.

再补充一个,上一例句中的提问句为:How

much

water

is

there

at

the

store?

考试中常遇到。
