浅议in front of…和in the front of的区别及其它

在英语中,有 的词组,有没有定冠词,会

引起意义上的变化。像in front of…和in the front of一样。in front of…是“在……的前面, 前方” 指在某一场所的外面;而in the front of…则是“在…的前 部(指某一结构本体的前部) There is a river in front of the hospital。The driver is sitting in the front of the bus。 用不用定冠词,意义发生变化的例子有: 1)at sea表示“在航行中,或海上航行”;而at the sea则表示 “在海边”。例如:when she woke up,the ship was at sea。 He spent the summer at the sea他在海滨度过了夏天。 2)in red表示“穿着红色衣服”;而in the red表示“亏损、负债” 例如:she is in red today今天她穿着红色衣服。 The foreign company was in the red last year。 3)by day在白天;by the day论日、按日 They explored the island by day他们白天在那岛上考察 The workers are paid by the day工人们按天计酬

4)three of us表示“我们中的三个人”;the three of us(共有三个人)Three of us visited the school。(“我们”的总数超过三人) The three of us went to Beijing last month(“我 们”的总数恰好是三个人) 5)go to bed就寝;go to the bed到床上去 what time do you go to bed?你通常几点睡? Will you please go to the bed and fetch my coat? 请你到床上取一下我的外衣好吗? 类似的还有:in the green(在年富力强的时候); go to school(去上学);go to the school(到学 校去)等等。这种一字之差,意义不同的情况,在 学习时,必须要引起注意,方能在今后的英语学习中, 不走弯路,不闹笑话。

happen是不及物动词,它的用法常见的有如下几种情况: 1. 表示"某地(某时)发生了什么事",常用"sth.+ happen +地点/时间"这一结构来表达,此时主语应是事 情。例如: The story happened in 2003. An accident happened in that street. 那条街上发生了 一起事故。 2. 表示"某人出了某事(常指不好的事)",要用"sth.+ happen+to sb."这一结构来表达。例如:A car accident happened to her this morning. 今天上午她发生了交通 事故。 What happened to you? 你怎么啦? 3. 表示"某人碰巧做某事",要用"sb.+ happen+ to do sth."这一结构来表达。例如:I happened to meet a friend of mine in the street yesterday. 昨天我碰巧在街 上遇到了我的一个朋友。

4. happen表示"碰巧或恰巧发生某事"时,还可用 "It happens / happened that..."这一结构来表达。 例如: It happened that Brian and Peter were at home that day. 碰巧那天布莱恩和彼得在家了。 It happened that he had to take part in a meeting that afternoon. 碰巧那天下午他不得不 参加一个会议。 注:that从句中的主语是人时,此种结构可以与 "sb.+ happen + to do sth."结构互换。例如: It happened that Brian and Peter were at home that day. = Brian and Peter happened to

be at home that day.
