题型:不详难度:来源:
Children will work actively if _______. A.praise | B.praised | C.praising | D.to praise |
|
答案
B |
解析
错因分析:有些考生会认为if后要用动词-ing形式,或用不定式表示还未发生的行为,于是误选C或D。其实,这是条件状语从句的省略形式,根据主语与动词的关系可知,孩子们受到表扬,于是正确答案选B。拓展:在时间、条件、让步、比较等状语从句中,当从句的主语与主句的主语一致,且谓语部分含有be动词时,则可将从句的主语与be动词同时省略。如:The old man will be very excited when talking (="he" is talking) about his past experiences. She will be unhappy if (she is) criticized. |
