課堂要點精析
一、情態(tài)動詞的基本用法
1．may與might的用法
(1)表示允許、許可。might在語氣上比may更委婉。以may/might開頭的問句在否定回答中要用mustn’t。
◆You may choose whatever you like.
你喜歡什么就選擇什么。
◆—May I stay in the room for a while?
——我可以在這個房間待一會兒嗎？
—Yes, you may./No, you mustn’t.
——是的，可以。/不，不可以。
(2)表示把握不大的推測，意為“有可能”。用于肯定句或否定句中；might語氣更加不肯定。
◆The traffic is very heavy these days.I may arrive a bit late, so could you save me a place?
這些天交通很擁擠，我可能會來晚一點，請你幫我留個位置好嗎？
◆She might go out because the phone was ringing all the time.
她可能出去了，因為電話一直在響。
2．will與would的用法
(1)表示意愿，would是will的過去式。
◆I will do my best to help you.我愿盡力幫你。
◆—Why didn’t you come to Simon’s party last night?
——你昨晚為什么沒有來參加西蒙的聚會？
—I wanted to, but my mom simply would not let me go out so late at night.
——我想去，但是我媽媽不愿意讓我晚上這么晚出去。
(2)表示征求意見或提出請求。would的語氣更加委婉。
◆Would you please come here to help me?
請你來這兒幫我好嗎？
(3)表示習(xí)慣或特性，以及自然的規(guī)律性。will用于現(xiàn)在，would用于過去。
◆Every morning he will have a walk along this river.
每天早晨，他總是沿著這條河散步。
◆She would do her homework in the library when she studied in the university.
當(dāng)她在這所大學(xué)學(xué)習(xí)時，她常在圖書館里做作業(yè)。

(1)shall
①shall用于疑問句中，表示征求對方的意見，這時可以用第一人稱和第三人稱。
◆Henry is waiting outside.Shall he come in, sir?
亨利正在門外等著，要他進來嗎，先生？
②shall用于陳述句，常與第二人稱或第三人稱連用，表示允諾、命令、警告和強制，或表示說話人的決心等。
◆You shall be punished for what you’ve done.
你會為你所做的事情受到處罰。
◆Tell Jerry he shall get a gift if he is nice.
告訴杰里，如果表現(xiàn)好，他會得到一份禮物。
(2)should
①表示責(zé)任和義務(wù)，意為“應(yīng)該”。
◆The children should be taken good care of.
這些孩子應(yīng)該受到好的照顧。
②表示推測，指有一定根據(jù)的推測，意為“按道理應(yīng)該”。

現(xiàn)在3點了。足球賽應(yīng)該很快就要開始了。
