1. I wasn't here yesterday.

動(dòng)詞是英語(yǔ)句子的核心，動(dòng)詞的時(shí)態(tài)要根據時(shí)間狀語(yǔ)或上下文來(lái)決定。本句的時(shí)間狀語(yǔ)是yesterday，be動(dòng)詞應該用其過(guò)去式was。be動(dòng)詞的一般過(guò)去時(shí)態(tài)肯定句常用句型是：名詞單數+ was... / 名詞復數+ were...；其否定形式是直接在was / were后加not；一般疑問(wèn)句是將was / were提到主語(yǔ)前面，句末用問(wèn)號。例如：Were you out?

2. I was a bit ill.

句中a bit可用a little替換，a bit和a little都可作副詞，修飾形容詞、副詞及動(dòng)詞，例如：I like noodles a little / a bit. a few則不能修飾形容詞和副詞，而a few和a little可作形容詞修飾名詞。a few修飾可數名詞，a little修飾不可數名詞，例如：We have a few good friends. There is a little water in the bottle. a bit雖然不能直接修飾不可數名詞，但a bit of卻能修飾不可數名詞。例如：He wants a bit of tea.

3. You'd better finish your homework soon, and bring it next Monday.

'd better為had better的縮寫(xiě)形式，意為"最好......"，其后接動(dòng)詞原形，否定形式為'd better not。例如：You'd better not be late again.

bring意為"帶來(lái)"，指從別處將人或物帶到說(shuō)話(huà)地，而take則指"帶走"，注意它們的方向。

4. Do you enjoy your work, Uncle?

enjoy意為"喜歡"，其后只能接名詞、代詞或V-ing形式作賓語(yǔ)，不能接動(dòng)詞不定式。例如：Do you enjoy being a journalist?

5. I called you last night.

實(shí)義動(dòng)詞的一般過(guò)去時(shí)態(tài)肯定句型是：主語(yǔ)+實(shí)義動(dòng)詞過(guò)去式（+賓語(yǔ)）+... 例如：I packed everything last night. 否定形式：主語(yǔ)+ didn't +實(shí)義動(dòng)詞原形+ ... 例如：She didn't remember my name. 一般疑問(wèn)句式：Did +主語(yǔ)+實(shí)義動(dòng)詞原形+...？例如：Did you have breakfast?
