题目

英语翻译
Animals can live only on____plants have already turned from inorganic to vegetable matter.
A.that
B.which
C.what
D.how
本题选:C
分析说:what+复数名词
which+单数名词
好象没涉及到that和which

Animals can live only on plants---- have already turned inorganic to vegetable matter.感觉正确的说法应是如此选that,由于前面有only所以不用which,这是定语从句的一个规则.另外象先行词有最高级修饰也只用that...
