英语四级备考课堂笔记及解析
1. It is time ________________ .
2. In the sports meeting, _______________ .
3. _________________ ，they enjoy true happiness.
4.The teacher always told us that ________________.
5. Since the examination is around the corner，________________.
答案与解析:
1. the authorities concerned took proper steps to solve the traffic problems
本题考点有两个。第一，考查 是......的时候了 的用法。翻译成英语可以说：It is time to dosomething或It is time that sb. didsomething.本句采用的是后一种虚拟语气句型。谓语部分要用过去时态。第二， 有关当局 应译成the authoritiesconcerned。Concerned的意思是 有关的.，有牵连的 ，常用于名词后面，修饰该名词。concerning的意思是 关于 ，通常不作后置定语。
2. he substituted for the injured player
替换某人 要用substitute for sb.，尽管汉语中只说 替换 ，翻译时要补上介词for，以符合英语的要求。 替换 还有displace，replace，swap，take theplace of，instead of等说法。这些表达之间有微妙的差别，考生要注意区分。substitute 代替;取代; 代替品Nothing can substitute for the advice the doctor is able to give you.substitute的用法是：substitute A for B，意为用A代替B;
replace 的用法是：replace A with B，意为用B代替A。
