※ 引述《minray (乌龟)》之铭言： : 以下3题,来自於图书馆借到的书... : 麻烦大家帮我解答疑问一下~~ : 感激了... : Weather forcasting has become very accurate,____the arrival of satellite. : A) with B) as : ANS : A : Q1 请问为什麽as不行呢? : Q2 有逗号跟没逗号会差在哪里呢? 下列使用是可以的 Weather forcasting has become very accurate with the arrival of satellite. Weather forcasting has become very accurate, as the arrival of satellite shows. 用as的时候 常用的是as+"sth."+verb as the case stands, ... as the number of cars grows, ... 有逗号我会用as. 不过用法错误 所以选A : _____ paying additional fees, always ensure you are within your aggreed limit : A) To avoid B) Avoiding : ANS : A : Q1 这样的有逗号的句型,中间没关代也没连接词,前後两句都有动词,是哪种句型呢? 这题比较基本 干嘛要加ing 难道你正在付多余的钱吗?? 後面已经清楚说了 "一直确认保持在限制内" 所以当然还没犯错罗! 句型就是文言文 下面是一般直述用 Always ensure you are within your agreed limit to avoid paying additonal fees. : Taiwan have been making education tools ____ brfore WWII : A) since B) around : ANS : A : Q1 请问around为什麽不对呢? around before WWII 听起来很怪 既然不能确定而使用around 又怎麽确定before哩? around WWII (OK) 希望有回答到你~ --
