21C who引导定语从句,先行词为 “the foreign experts”,所以动词用复数；
22D.先行词作宾语,关系代词可省略,而宾语为the man,nod为不及物动词,因此和宾语之间需介词连接.AB排除,C因为是定语从句,关系代词就是做了宾语成分,真正宾语就不该再出现了
23D 此句仍为定语从句,先行词a single person在从句部分做宾语,关系代词可用who或whom.turn to sb (for help)为固定搭配.
24D 首先talk about 可视为固定搭配,talk为不及物动词.先行词the novel 作宾语,关系代词可省.
25A 先行词The matter 后面定语从句关系代词做宾语且不及物动词后已经有介词,所以只有A
26B 定语从句关系代词作宾语,当先行词things and persons里有物有人,只能用that了.
27B 不定代词做先行词时关系代词只能用that.D排除,A语法不对.物体belong to sb.这里没有被动关系,应该用主动语态."Is"和"anything"都预示了后面的动词应该用单数,所以B而非C
28D 根据句意关系代词应该为物主代词
29A 先行词为the only one （one 代指boy)所以定语从句部分谓语动词应该用单数.该题于第23区别在于定语从句修饰的部分不同.
30B 从句life has developed gradually修饰planet先行词,然而从句部分又不缺成分的,故应该用关系副词.planet又是表示地点的,所以选B
