say.

前几天帮同学看作文，其中一段前两句话如下：
Stopping reading or listening to the news for a while can improve
people’s mental health. That is to say, nowadays there are more
and controversial contents in the news.
同学可以先想看看你觉得这里that is to say用对了吗？如果不适合，怎么
改比较好呢？先想想再往下看喔！
首先我们先看字典定义，韦氏字典有两个解释：
1—used when giving more accurate or specific information about
someone or something that was just mentioned
We—that is to saymy wife and I—will be attending the wedding.
2—used when giving information that affects something previously
mentioned
We plan on going to the concert—that is, if tickets are still
available.
Cambridge dictionary的解释：
or moreexactly
更确切地讲；也就是说
Ourfriends, that is to sayourson'sfriends, willmeetus at the
airport.
我们的朋友，更确切地讲是我们儿子的朋友，会到机场接我们。
其他例句：
- They, that’s to say Matt and John, were arguing about what to
do.
- Languages are taught by the direct method, that is to say, without
using the student’s own language.
根据以上两个字典的解释跟例句我们可以知道that is to say是要对“刚刚
提及的概念”提出“更具体的资讯”，不要因为一直想用转折词凑字数，或
是觉得第一句主题句讲完下一句就要接That is to say, 而乱放。
另外根据上面的例句来看，应该会发现that is 比较常用在两个逗号或两个
破折号(em dash)之间，或是一个破折号再接一个逗号。
那同学的这个句子应该怎么改比较好呢？有两个方向可以改改看。
1. 如果想保留that is to say, 可以这样写：
Stopping reading or listening to the news for a while can improve
people’s mental health, that is to say, our emotional or
psychological well-being.
用our emotional or psychological well-being补充解释什么叫做 “
mental health”
2. 如果想维持原本接下来想表达的句子，该怎么办呢？如果不适合放转折
词，其实很多情况就是直接写下去，不要放，如下：
Stopping reading or listening to the news for a while can improve
people’s mental health. Nowadays there are more and controversial
contents in the news.
从这三篇的提到的转折词Furthermore, In other words, That is to say,
同学应该更知道如何精准的使用转折词。使用的当，可以让作文更加分，因
为官方有明确提到appropriate word choice and idiomaticity 也是评分
标准之一，用不好反而还可能因此扣分，得不偿失喔！
最后再提醒同学，合适地放转折词可以让文章更通顺、流畅，但如果没把握
这两句之间适不适合放转折词，其实就直接写下去，不放也没关系喔！
