{01}I really wonder ______ he has posted me many parcels _____ we worked together . A.how ; after B.why ; when C.when ; before D.why ; since
解析:英语中的连词since有这样的特性:终止其后从句中的延续性的谓语动词的动作。第二个空白处填入since之后,这个从句的意思是:自从我们不在一起工作起。此外,since还可使其后从句里的非延续性的谓语动词延续。例如:It is 15 years since he joined the Army . (他参军已经十五年了。) 本题选D。 {02}-Do you think we can get there on time? -Yes,_______ the truck doesn’t break down. A.even if B.unless C.until D.so long as
解析:so long as=if。unless"除非"…unless the truck breaks down. 【译文】—你认为我们会准时到达那儿吗?—会的。只要车不出问题。 本题选D。
