1. They just want us to practise getting out of the school in case there is a real fire one day. (P26) (just) in case 表示“如果,假如;以防(万一)……”之意,可单独使用或后跟“of...”及从句。如: It may rain — you'd better take an umbrella (just) in case. 可能会下雨,你最好带把雨伞。 In case of fire, call 119. 万一失火的话,请拔打 119。 Please remind me of my promise in case I forget. 万一我忘了,请提醒我许下的诺言。 2. I wish we could go back inside. (P27) wish 后跟that 引导的宾语从句,常表示某种未实现或无法实现的愿望或希望,有“但愿”之意,故从句中动词往往用过去时态来表示一种虚拟的意愿。如: How I wish I were you!假如我是你,那该多好啊! I wish I knew what is happening.但愿我知道现在正在发生什么事。 She wished she had stayed at home. 她遗憾当时不在家。(她多么希望她当时在家)。 3. They can lower your risk of injury by 45%. (P33) 当表示“增加或减少了……”时,常用介词by; 当表示“增加或减少到……”时,常用介词to。如: The output of our factory this year has increased by 30 percent more than it was last year. 我们厂今年的产量比去年增加了百分之三十。 You must reduce your expense to half what it was last month.你必须将你的费用降低至上个月的一半。 4. But country kids are just as likely to lose control of their bikes. (P33) 句中的as为副词,后接形容词或副词。本句为省略句,省去了“as city kids are”,在“as...as”句型中,根据上下文,如果意思较为明确的话,后面的连词as引导的从句往往省略。如: He runs fast and I can run as fast (as he runs). 他跑得很快,我也是。 They all work hard; I am as diligent as (they are). 他们学习都很刻苦,我也很勤奋。 5. Once inside, she glanced out the window to see if anyone was there. (P34) 此句中“once”为从属连词,引导时间状语从句,句子采用了省略的形式,完整句子应为“Once she was inside...”。 英语中从属连词引导的时间、条件和让步等状语从句中,如果从句的主语与主句的主语一致或从句主语为“it”,且从句为“主语——系动词——表语”结构时,从句往往采用省略形式,即只保留从属连词和表语部分。如: When (he was) in London last year, he made a lot of good friends. 去年他在伦敦期间结识了很多好朋友。 Although (he was) busy, he always spares his son some time for the weekends. 尽管他很忙,他总是抽出些时间陪儿子度周末。 If (it is) possible, I will come to help you with your English. 如果有可能的话,我就会过来帮你学习英语。 (文/靳涛; 英语辅导报冀教高一版 04~05学年度第13期;版权归英语辅导报社所有,独家网络合作伙伴新浪教育,未经许可,不得以任何形式进行转载。) |
