Question

The problem is too difficult for him. He _______ solve it by himself without any help.

A．can't

B．mustn't

C．shouldn't

D．needn't

Answer 1

A

試題分析：can't不能，不可能；mustn't禁止；shouldn't不應(yīng)該；needn't不必。句意：這個(gè)問(wèn)題對(duì)他來(lái)說(shuō)太難。沒(méi)有幫助他自己不可能自己解決。故選A。
點(diǎn)評(píng)：情態(tài)動(dòng)詞的考查是初中英語(yǔ)考查的重點(diǎn)，平時(shí)學(xué)習(xí)中一定要熟記這些詞的基本詞義及用法上的不同，注意其用法及在句子中表達(dá)語(yǔ)氣的不同。考試中結(jié)合語(yǔ)境選擇合適答案。
