He said he is busy. That is,a game of tennis made him very busy.
请老师分析一下这句话的结构,that is 后面为什么要用逗号?把 made 换成 making 可以吗?
黎老师:
正确的句子应该是:
He said he was busy.That is,a game of tennis made him very busy.
1. 不能把 made 换成 making,因为 made 是谓语动词,a game of tennis 是主语,making 是非谓语动词,不能作谓语。
2. that is = that is to say [副] (外研社、建宏《英汉多功能词典》),通常应该用逗号与句子的其它部分隔开,意思是“亦即”“那就是说”“换句话说”等。例如:
Languages are taught by the direct method, that is to say,without using student's own language. 语言教学使用的是直接教学法,也就是说,不用学生的母语。
I loved him—that is, I thought I did. 我当时是爱他的,或者说,我以为我是爱他的。
(《朗文高级英语应试词典》)
He will leave Japan next Saturday, that is, June 6th. 他将在下星期六,也就是6月6日离开日本。(外研社、建宏《英汉多功能词典》)
3. 最新出版的《牛津英语用法指南》第三版认为 that is to say 是一种“话语标记”,指出:“在说话人 / 作者用另一种方式将某事重说一遍时,就用 that is to say 或 in other words。如:
We cannot continue with the deal on this basis. That is to say / in other words , unless you can bring down the price we shall have to cancel the order. 我们不能继续在这个基础上进行交易了。也就是说/换句话说,除非你降低价格,否则我们不得不取消定货。”
