3道英文选择题简单说下原因
40,I don”t feel very well.Mum asked me _______ this morning.A,what the matter is B,what is wrong C,what the matter was D,what wrong was 41,the bridge _______ a big ship can go has been built.A,under which B,under that C,in which D,on which 42,he talked about the classmates and the school ______he had visited.A,who B,that C,which D,about which

答案

40.C 妈妈今天早上问我,应为过去时态,A,B 排除,因为时态不对.C对,问出什么事了,应用what is the matter,今早妈妈问的,应为过去时态,is改成was,.what was the matter.由于what was the matter 是asked 的宾语从句,而在所有从句中都要用陈述句的语序,故应将was放在主语matter 之后,宾语从句就是what the matter was.D不对,因为在what is wrong中wrong是形容词,不可能将作表语的形容词wrong放在系动词之前.
41.A.under which对,因为a big ship can go 是bridge的定语从句,先行词是bridge指物,关系代词当然选which,可是船在桥下过,因此就要用介词under,本来这个句子是The bridge which a big ship can go under(which) has been built.,现在将介词under提到关系代词which前了.B不对,因为只有under which没有under that.C不对 因为which指桥(bridge),船不能在桥中过,in which是介词错了.同理D也不对,不能用介词on,船不能在桥上过.
42.我个人的意见是B和C都对,因为he had visited 是school的定语从句,school 是先行词,指"物",当先行词指物同时关系代词在后面的定语从句中作宾语时,可以用that 和which 作为关系代词.这时的that=which.A显然不对,因为先行词不是指人,当然不能用who D也不对,应将about去掉,理由是visit是及物动词,可以说visit school,根本用不着介词,不可能说visit about the school.
