**介詞部分**
1. 表示交通方式時(shí),“by + 交通工具”中間不加詞,若交通工具前有修飾詞,則用“in/on + 交通工具”。例如:“He usually goes to school in his father’s car.”
2. “wait”為不及物動(dòng)詞,需加“for”才能接賓語(yǔ),如“Please wait for me at the school gate.”
3. “marry”與“to”連用,“He has been married to Betty for more than twenty years.”
4. “在……的幫助下”用“with”,如“He finished the work on time with the help of him.”
**情態(tài)動(dòng)詞部分**
1. 表特別有把握的肯定判斷用“must”,否定判斷用“can't”,“can”表判斷只用在否定句中。所以“He can be at home now because the light in his room is still on.”應(yīng)改為“He must be at home now because the light in his room is still on.”
2. 情態(tài)動(dòng)詞“need”用于否定、疑問(wèn)和條件句,肯定句中用實(shí)義動(dòng)詞“need to do”。例如:“He needs to come here before the meeting begins.”
3. “used to”表示過(guò)去常常做某事而現(xiàn)在不再做,“He used to get up very early in the morning, but now he is not doing so.”
4. 談?wù)撨^(guò)去的事情時(shí),情態(tài)動(dòng)詞后加“have done”,“I needn’t come yesterday because all the work had been finished.”應(yīng)在“needn’t”后加“have”。
5. “had better”的否定在“better”后加“not”,如“You had better not stay up too late because you have to get up early tomorrow.”
**動(dòng)詞的時(shí)態(tài)部分**
1. 主句為將來(lái)時(shí),其時(shí)間、條件、方式和讓步狀語(yǔ)從句中用一般現(xiàn)在時(shí)。“I will tell her about that when she comes tomorrow.”
2. “be about to”一般不與具體的時(shí)間狀語(yǔ)連用,“The meeting is about to begin.”
3. 若為并列謂語(yǔ)動(dòng)詞,時(shí)態(tài)應(yīng)保持一致,“The boy opened his eyes for a moment, looked at the captain and then died.”
4. 句中有“for + 一段時(shí)間”作狀語(yǔ)時(shí),謂語(yǔ)動(dòng)詞須為延續(xù)性動(dòng)詞,“I have kept this bike for ten years and I am still using it now.”
5. 過(guò)去的過(guò)去用過(guò)去完成時(shí),“I hadn’t learnt any English before I came here.”
