But it_ be.A.might B.will C.must D.can答案與解析1.A 解析 你這是什么意思，只有十張票嗎?應該有十二人。should表示“應該，應當”。2. C考查情態(tài)動詞的用法。答話的人提了一個建議你應該關注別人對你的評價的。should可以用

33、來向別人提建議，所以答案為：C3. A解析 may表達推測之意，意為“可能”。4.B must必然，一定；can可能；should應該；would（過去）將，總會。本題提供的語境是“有時可能會”。5. C考查情態(tài)動詞的區(qū)別。will可用來表示“意愿；客觀必然性等”；would可表示“意愿；過去常常（現在也可能是那樣的）”；should表示“應該，理應”；must表示“必然；一定，準是”。結合語境可知，此處用should表示虛擬。句意為：“這本來應該是美麗的，但是現在它被嚴重污染了?！?.A shall在問句中征求對方意見，主要用于第一人稱。答語句意為：“我給你拼寫一下好嗎？”7.

D “情態(tài)動詞+have done”構成的虛擬語氣用法。答語句意為：你本該上周就告訴她(其實沒告訴她)。10.A解析“I am not sure”說明說話者對情況沒有把握，推測語氣較弱，使用might。二、完形填空Many people think that Americans 1 their cars almost more than anything else.
