问题补充:
Every year, typhoons and losses lead to are frightening though measures have been taken.
A. which
B. that
C. they
D. ones
答案:
A. which
B. that
(答案→)C. they
D. ones
解析:本题定语从句的先行词是losses,后面定语从句的主语是they,they指代名词typhoon在句中做主语,在losses后面省略了that,that指代先行词losses作为动词短语lead to的宾语,可以省略。句义:每年,台风以及台风带来的损失都是很可怕的,尽管很多措施已经被采取了。故C正确。
