1. I wasn't here yesterday.
動詞是英語句子的核心，動詞的時態(tài)要根據(jù)時間狀語或上下文來決定。本句的時間狀語是yesterday，be動詞應(yīng)該用其過去式was。be動詞的一般過去時態(tài)肯定句常用句型是：名詞單數(shù)+ was... / 名詞復(fù)數(shù)+ were...；其否定形式是直接在was / were后加not；一般疑問句是將was / were提到主語前面，句末用問號。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(shù)名詞，a little修飾不可數(shù)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(shù)名詞，但a bit of卻能修飾不可數(shù)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的縮寫形式，意為"最好......"，其后接動詞原形，否定形式為'd better not。例如：You'd better not be late again.
bring意為"帶來"，指從別處將人或物帶到說話地，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，不能接動詞不定式。例如：Do you enjoy being a journalist?
5. I called you last night.
實義動詞的一般過去時態(tài)肯定句型是：主語+實義動詞過去式（+賓語）+... 例如：I packed everything last night. 否定形式：主語+ didn't +實義動詞原形+ ... 例如：She didn't remember my name. 一般疑問句式：Did +主語+實義動詞原形+...？例如：Did you have breakfast?
