Answer 1

B

試題分析：句意:當馬克被問做教師這個職業(yè)時的看法。他說他發(fā)現(xiàn)這個工作是非常有趣和值得的。這里when引導的省略句，完整的是when he was asked his view about his job as a teacher，這里當從句中的主語與主句的主語一致，并且從句的謂語動詞有be時，這時從句的主語與be同時省略，故選B。
點評：本題難度適中。為了使話說得簡明扼要，英語句子中某個單詞、短語甚至從句或主句都可以省去。這種省去句子某些成分而保持句子意思不變的現(xiàn)象，稱為省略。它是高中階段的重要的語法項目，需要考生仔細分析句子結構，來確定省略的內容。這里考生容易誤選A。
即學即練:He is rather difficult to make friends with, but his friendship，______ is more true than  any other.
A.once gained                          B.when to gain
C.after gaining                        D.while  gaining
解析：A�？疾槭÷跃�。once gained =" once" it is gained。當狀語從句的主語和主句的主語一致且從句中含有be動詞時，可省略從句中的主語和謂語部分。
