Lesson 42 Not very musical首先，我们检查一下课文的背诵和生词的默写。接下来我们来重点讲解课文。1. as文中的as作为因为讲，as 还有以下几种用法： 引导时间状语从句，“当时” eg: We were playing cards as the rained stopped. “随着” eg: As time goes by, everything is changing. “一边一边”eg: The performers sing as they dance. 引导让步状语从句，表“尽管，虽然”，且必须用倒装结构，如倒装到句首的是单数名词，要去掉a/aneg: Child as he is (=Even though/Even if/Although/Though/While he is a child), he knows much more than we expected. 引导方式状语从句，表“按照”eg: Is this dress too casual? -You can go _ you are.A. like B. as C. what D. how2.“have +名词”“have +名词”代替普通动词表示“完成该动作”：have a bath=bathe ；have a swim=swim；have awalk=walk；have a look=look；have a rest=rest；have a smell=smell 等，类似的动词有dance，fight，ride，talk，sleep，washeg: I had two dances with Lucy.Jim and I have just had a long talk.一个动词的后面会加介词(如果这个动词是不及物动词)，动词能加什么样的介词，名词也可以加什么样的介词.3. through / acrossacross 和 through 都可表示“横过”或“穿过”，前者主要表示从某物的表面“横过”，涉及“面”的概念；而后者则表示从某个空间“穿过”，涉及“体”的概念。eg:He walked across the road carefully. 他小心地走过马路。 He walked through the forest alone. 他独自一人走过森林。有时 across 表示“横过”也可在“体”内进行，但此时它仍与through 有差别：前者表示从某个“体”的一端到另一端，而后者表示穿过两端。如：eg: He walked across the hall. 他从大厅的一端走到另一端。 He walked through the hall. 他穿过大厅。注：与抽象名词连用，表示“通过”，一般只用 through。如：eg: He became richer through hard work. 他勤奋致富。 在美国中，可用 from . through 表示“从到”(此时不用along 或 across)。eg: We work from Monday through Saturday. 我们从星期一到星期六工作。4. 定冠词The1) 指上文所提到过的人或物，如：I have a cat.
