Should的用法
1.should后直接跟動(dòng)詞原形，沒有人稱和數(shù)的變化, 如：
You should go home at once.He should eat more vegetables.I should finish my homework before nine.should的否定形式是在should后面加not, 可以縮寫為shouldn’t, 意為“不應(yīng)當(dāng); 不應(yīng)該”。如:You should not / shouldn’t insult her. 你不應(yīng)該羞辱她。
2.should作為情態(tài)動(dòng)詞最基本的'意思是“應(yīng)該”，既可指建議或勸告某人“應(yīng)該”做某事，也可指有責(zé)任或義務(wù)“應(yīng)該”做某事，如：You should tell your mother. 你應(yīng)該告訴你的媽媽。
3.should可以與say, think, imagine等動(dòng)詞連用，使語氣變得委婉，如：I should say he is an English teacher. 我想他是一位英語老師。I should think it is a good song. 我想那是一首好曲子。
