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。
