同学们请尝试下面根据主题陈述句写出段落主题句的两道模拟题 （考试的第三道大题）

1.

Thesis statement: The rise of social media has significantly altered the way we communicate, leading to both positive and negative effects on interpersonal relationships.

Topic sentence 1: _____________________________________

Topic sentence 2: _____________________________________

2.
Thesis statement: Climate change is the most pressing issue of our time, requiring immediate action from governments and individuals alike to mitigate its effects.
Topic sentence 1: _____________________________________
Topic sentence 2: _____________________________________

记得认真阅读已给主题陈述句（thesis statement），找到关键信息 (topic, controlling idea, subtopics/overview)，这些关键信息都能帮助大家写出切题的两个段落主题句（topic sentences）。

检查这道题的时候记住：
1. 确保主题句是完整的句子，不要写短语，不要有语法错误
2. 确保主题句的第一个单词的第一个字母大写
3. 确保主题句以英文的句号（.）结束，不要漏掉了句号，切切!

Put on your thinking cap and give it a go, class!

Thesis statement: The rise of social media has significantly altered the way we communicate, leading to both positive and negative effects on interpersonal relationships.
Topic sentence 1: Social media helps us communicate with each other more conveniently than before.
Topic sentence 2: Social media is easy to get some people addicted to it, and it will influence the relationship between them and their family or friends.

这两句主题句的标点和大小写以及句子构成都非常好；从内容上来说，第一个正文段落聚焦正向影响，第二个正文段落聚焦负面影响，符合中心思想句中的controlling ideas。非常好。

唯一还可以改进的地方，是这两个主题句之间的逻辑关系，未见清晰呈现：如果在主题句中点明，就更好了。细节的地方表述可更精确一些：比如不是所有使用社交媒体的都会成瘾，你这里写了some people做限定，非常好，但如果再加上overuse是不是会更准确一些呢？

可以比较一下参考答案：

1. On the positive side, the rise of social media has facilitated instant communication and connection, allowing individuals to maintain relationships across vast distances more effortlessly.

2. However, the pervasive use of social media has also led to a decline in face-to-face interactions, potentially weakening the depth and authenticity of interpersonal relationships.

2.
Thesis statement: Climate change is the most pressing issue of our time, requiring immediate action from governments and individuals alike to mitigate its effects.
Topic sentence 1: The government should make some policies to reward or punish the behaviors which are good or bad to the climate.
Topic sentence 2: The individuals should pay attention to the climate protection, try to do related things around us and give an immediate stop to the people who destroy the climate.

同上，标点、大小写都很好，内容上也紧扣政府与个人的行动，呼应中心思想句的controlling ideas，非常好。

需要改进的地方，是词汇表达显得较为初级内容显得较为空泛，比如 the behaviors which are good or bad to the climate; do related things; destroy the climate

另外：individuals此处不要定冠词，表示泛指。

建议搜索相关资料，具体找到一些政府和个人需采取的相关行动，对其进行归纳总结，然后形成各自的主题句。

参考答案如下：

1.Governments must take bold steps to reduce greenhouse gas emissions and investin renewable energy sources to effectively combat the adverse effects of climate change.

2.Individuals can also play a crucial role in mitigating climate change by adopting sustainable practices and supporting policies that aim to protect the environment.

Xiaojing好：

下面我们来看看针对这两个中心思想句你给出的主题句


Thesis statement: The rise of social media has significantly altered the way we communicate, leading to both positive and negative effects on interpersonal relationships.

1.We can see our family through video calls on our phones when we are in different areas.
2.Since social medias,there is less emotional communication, and feeling become weaker.

首先，原中心思想句中提到了正面和负面的影响（both positive and negative effects），而你给出的两个正文段落的主题句，刚好是一正一负，并且排序（先正后负）也符合中心思想句给出的预期。而且，你的主题句都是关于人们之间的交流，完全对应了中心思想句中（the way we communicate）, 所以切题方面非常好。

接下来，你的主题句主要需要从两个方面来进行修订：
1）首先，这两个主题句各自统领一个正文段落。光看这两个主题句，我们很难发现它们之间的逻辑关系（应该是列举，是因果，或是转折？）。读者读完第一个正文段落后，看见第二个正文段落的主题句就会有点懵。你作为作者要主动告诉读者接下来的这一段跟上一段之间的逻辑关系，需要用相对应的transitional phrases等直接向读者明示。

2）目前你的两个主题句的写法需要进一步修订。第一个主题句稍显具体，需要提炼一下，视频交流应该属于提炼后的一个例子（比如相比以前，社交媒体缩短了交流的时空，那么视频交流就可以作为一个例子给出）；第二个主题句的表达又有点太宽泛，比如你主要指的是在哪类场景中现在出现了less emotional communication？feeling becomes weaker也显得有点意思不够明确。

1.We should use energy-efficient public transportation more often and reduce our reliance on gas-powered vehicles.
2.Goverment should enhances publicity and education of energy conservation low-carbon.

这两个主题句首先需要换一下顺序，因为中心思想句中先提到政府，再提到个人 （immediate action from governments and individuals ）。
第二个主题句中的energy conservation 和 low-carbon之间的逻辑关系是什么？不能直接列举信息哦。
然后我们看人称：中心思想句使用的是复数governments，你的第二句是第三人称单数的government，建议改为复数表示governments in general, not a specific one。

加油加油！
