23、的 sound noisy 听起来吵闹 59 worry about = be worried about 为担忧 60 lie on the bed 躺在床上 2006年2月12日星期日1.Why not? (L.110)这句话应该怎样理解？Why not?意为为什么不？常用来表示建议或质疑，常把动词省去，故上句可全写为： Why not go by train? Why not.? (后接动词原形)：为什么不？(=Why dont you.?) 又如：Why not play basketbll? 为什么不打篮球呢？(=Why dont you play basketball?)2. It

24、 takes too much time. (L.110) take怎样理解该句及句中take的用法？3. Dont you usually come to school by bike? (L.111) 该句是什么句型及如何使用？此句是否定疑问句，常用来表示惊奇、责难、赞叹、建议或有礼貌的邀请等。一般疑问句的否定答语与一般疑问句的肯定答语相同，只不过这时yes译为不， no译为是。又如：Dont you want to go home?难道你不想回家吗？Yes, I do. 不，我想回家。No, I dont. 是的，不想。4. Yes, walking is good for health

25、. (L.117) 该如何理解？walking 作句子主语，相当于名词，语法上称为动名词，这时谓语动词用单数形式。5. Sometimes he plays games after school.(L.106) I usually come by bus. (L.110) I dont take the bus often, only when it rains. (L.117) sometimes, usually, often 是表示行为或动作频率的副词，它们在句中位置为什么不同？usually, often, sometimes 用在句中时，常放在be动词之后，实义动词之前。如谓语是由助

26、动词或情态动词主要动词构成，频度副词放在第一个助动词或情态动词之后。加强语气时，可放在句首或句尾， often置于句尾时常被very或much 修饰。频度副词之频率：日一二三四五六usually 通常 O O O一O O Ooften经常 一O O一O O一sometimes 有时 一O一一O一一6. So Im often late for school,said Sun Yang with tears in his eyes. (L.112) 句中 with tears in his eyes 词组如何理解？因此我上学常常迟到，孙杨说时眼含泪水。with tears in his eyes

27、表示伴随状况，在句中作状语，属于with+名词介词短语/形容词/V-ing结构，又叫独立格结构，除了作状语表达伴随动作/方式外，还可以作定语。又如：7. How much is the., please? (L. 114) How much are the., please? (L.114) 两句以how much 开头，而动词be形式不同。为什么？how much 用来修饰不可数名词和询问价格。上面两个句用来询问价格，询问的物是不可数名词，即不可数名词作句子主语，用系动词is；询问的物是可数名词复数(泛指同一类事物)，即可数名词复数作句子主语，用系动词are。又如：How much is t

28、he fish, please?鱼多少钱？How much are the onions, please?洋葱多少钱？8. They help you find what you want. (L.116) 以what 开头的特殊问句，常用疑问语序，为什么此句用陈述语序？以what, where, how等疑问词开头的句子，不用在句中而是单独成句，这它是特殊问句，要用疑问语序；若用在句中动词后，这时不是特殊问句，而是宾语从句，故用陈述语序，不能再用助动词等。又如：He asks her what she wants. (L. 116) 他问她想要买什么。9.What about by plan

29、e? (L.117)介词about之后为什么又跟介词，而不跟名词？What about.?句中的about 为介词，后跟名词或V-ing形式。上句应视为省去V-ing(根据上文应为going home的省略句)，主句应为：What about going home by plane?10. He is wearing a hat and working in the fields. (L.119) 表示状态的动词，像wear，不能用进行时，为什么这里却用了？wear 穿着、戴着表示状态，用一般现在时，表示每天的持续性动作，进行时表示暂时的状态。比较：He always wears a hat.

30、 他总是戴一顶帽子。He is wearing a hat today. 他今天戴了一顶帽子。26. 1. dangerous = in danger The man looks dangerous. = The man is in danger.dangerous for 对.有危险The river is dangerous for children.27. help 1. help sb. with sth He helps me with English.help sb .(to) do sth He helps me study English.cant help + v-ing 忍

31、不住 He cant help crying.alone adv. 单独.独自 = by oneself I went alone.10ask sb.(not) to do sth. 意为“让某人(不要)做某事”，其中ask sb.后应接动词不定式，如：Ask your friends to guess what is in it. (L44)11show sb. sth. / show sth. to do. 意为“把某物给某人看”，该句型的用法同前面第2点。如：Show your friend your family photo.（L36）/Show your family photo t

32、o your friend.12introduce sb. to sb. 意为“把某人介绍给另一人”；introduce to sb.则是“向某人作介绍”。如：Introduce your family to her. 3It takes sbsome time to do sth此句型表示“干某事花了某人一段时间。”其中的it是形式主语，后面的动词不定式（短语）才是真正的主语。例如：It took me half an hour to finish the hard work完成这项艰巨的工作花了我半个小时。4thinkfind + it + adj. + to do sth.此句型中的it是形式宾语，不可用其它代词替代，形容词作宾语的补足语，后面的动词不定式（短语）才是真正的宾语。例如：I found it important to learn English well. 我发现学好英语很重要。5Whats wrong with？此句型相当于Whats the matter/ trouble with？后跟某物作宾语时，意为“某物出什么毛病了？”后跟某人作宾语时，意为“某人怎么了？”例如：Whats wrong with your bike？你的自行车出什么毛病了？一Its broken它坏了。Whats wrong with you？你怎么了？一I hav
