hasn’t been able to quit smoking,but at least he has cut . 5.down。句意:我叔叔還未能戒煙,但至少他已經(jīng)少抽了。cut down為固定短語,意為“減少,刪減”。 6.I feel (confidence)in recommending Mr Jackson to you for the post,for he is quite experienced in the field. 6.confident。本句中的謂語動詞feel為系動詞,空處應(yīng)用形容詞作表語,故填confident。,7.(2013·浙江高考改編)I couldn’t have enjoyed myself (much)—it was a perfect day.

bined。句意:她既有天生的謙恭有禮的舉止,又有堅定不移的信念。分析句子結(jié)構(gòu)可知,空處應(yīng)用過去分詞作后置定語。,10.(2011·江蘇高考改編)—I left my handbag on the train,but luckily someone gave it to the railway officials. —How unbelievable to get it back!I mean,someone have stolen it. 10.might。從對話情景可知,他們在談?wù)撨^去的可能性:手提包當時有可能會被偷去,因此用might have stolen。,二、單元話題微寫作 健康飲食 根據(jù)提示,將以下句子連成一篇英語短文。 1.現(xiàn)如今人們已經(jīng)意識到健康的飲食習慣的重要性。
