广州牛津版九年级下册Unit 3 The environment More practice
广州牛津版九年级下册Unit 3 More Practice➢短语收藏夹1. have a normal life 捡起……；拾起……2. the same as 与…一样3. full of ... 装满，充满4. pick up 捡起5. the rest of 剩下的……；其余的……6. for a while 一会儿7. wake up 醒来8. keep doing 不断做某事；继续做某事9. cover…with…用…覆盖..10. thousands of 成千上万的11. somewhere else 其他地方➢课文解释1. The woman took me home and put me in the fridge. 这个妇女把我带回家并且把我放进冰箱里。
解析：take ... home意为“把……带回家”，注意home 在此为副词，其前面不能有介词to。
“把……带到某地”则用“take ... to+地点名词”表达。
例如：妈妈，这只小狗很可爱。
我可以把它带回家吗？Mum, the little dog is lovely. Can I take it home?我只好把这个老人带到派出所。
I had to take the old man to the police station.2. Then I was pushed together with the rest of the rubbish.然后我和其余的垃圾被压在一起。
解析：the rest of 意为“其余的；剩余的”，后面可接可数名词、不可数名词或代词；该短语在句中作主语时，谓语动词的单复数形式要与其后面的名词的单复数保持一致。
例如：我们踢足球时，你们其余的人做什么呢？What will the rest of you do when we play football?我爷爷在老家度过他的余生。
My grandpa spent the rest of his life in my hometown.3. When I woke up, I found myself in a terrible place.当我醒来时，我发现自己在一个很可怕的地方。
牛津版(深圳 广州)英语九下 Unit 3 The environment 第2课时(Readi
第2课时Reading阅读课堂精讲重点语句解析一、课本原文二、重点语句解析1. Without it, the Earth would be the same as the Moon-cold and lifeless. (P35，L8)没有大气层，地球会变得跟月球一样阴冷而没有生气。
解析(1)本句是虚拟语气，句中的without …相于if there weren't …。
使用虚拟语气时，若表示与现在事实相反，则从句要用一般过去时(be用were不用was)，主句用would/should/could/might+动词原形。
(2)(be)the same as表示“类似，相同”，通常指某个事物跟另一个事物很像。
举例Without the Sun, nothing would grow.没有太阳，什么东西都不会生长。
His last name is the same as mine.我们同姓。
运用(1)We couldn't finish our work so early ____________ your help. Thank you!(2)这条连衣裙跟我的一样。
(汉译英)_______________________________________________________________________________2. When we burn fuels such as petrol and coal, we produce a gas called carbon dioxide (CO2).(P35，L11)当我们燃烧如汽油和煤这些燃料时，我们产生一种叫二氧化碳的气体。
解析when在句中引导时间状语从句。
而called carbon dioxide则充当后置定语，修饰gas。
举例It happened when I was living in the country.这事发生在我住在农村的时候。
