大学英语四级单句改错例题解析（最终版）

大学英语四级单句改错例题解析（最终版）第一篇：大学英语四级单句改错例题解析（最终版）单句改错例题解析【例1】Sorry，I haven't got any small changes on me．【解析】这里的“changes”应改为“change”，因为“change”作“零钱”解时为不可数名词。

【例2】Is the education free in all the countries？【解析】这里“education”前面的“the”要去掉，因为抽象名词表示泛指意义时不用定冠词。

【例3】Peter is stronger than him．【解析】在省略句或不完整的从句中，代词的格应跟没有省略、完整时的格一致。

这一句完整的结构应该是“Peter is stronger than he is，因此不能用“him”。

【例4】The man bought 20 dozens socks．【解析】象dozen，hundred，thousand等数量词被大于1的基数词修饰时，仍用单数形式。

所以这里的“dozens”应该改为“dozen”。

【例5】M illion of years ago，there lived a lot of huge animals on the earth．【解析】“hundreds of”，“thousands of，“millions of等结构中，不可遗漏-s。

【例6】China is still a developed country．【解析】过去分词作定语表示完成或被动之意，而现在分词作定语则表示进行或主动之意。

而中国现在仍然是一个发展中国家，因此应把“developed”改为“developing”。

【例7】What a ashamed thing to do！【解析】“ashamed”是“感觉羞耻的”，通常很少用在形容词前面作定语，一般只作表语，而“shameful”是“可耻的”，通常用在形容词前面作定语。

例3：However，a second person thought that this was more a question of civilized behavior as good manners．（2000年6月第73题） as应改为than，more．．．than．．．为固定句型搭配， 2．单词的混用：这种错误是指误用了某个在形式或意义上与正确的单词相似的单词。

例1：Between sunrise and sunset，streets and highways are a constant source of voice from cars，buses and trucks．（1995年6月第 73题）原文讲述噪音污染，所以，此处的voice应改为noise。

四级英语短文改错真题

四级英语短文改错真题Recently, I have came across an interesting article about a study which examined the impact of using smartphones on students' academic performance in class. According to the study, the findings showed that there are both positive and negative effects of using smartphones in the classroom.On one hand, smartphones can be a useful tool for learning. With access to the internet, students can easily search for information and resources related to their studies. This can enhance their understanding of the subjects and broaden their knowledge. Moreover, there are many educational apps available that can help students practice and improve their language skills, math abilities, and other academic areas.On the other hand, smartphones can also be a distraction in the classroom. Many students are tempted to use their phones for non-academic purposes during class time, such as checking social media or playing games. This can lead to a lack of focus and lower academic performance. Furthermore, the use of smartphones can create a barrier between students and teachers, as it may discourage face-to-face communication and interaction.In my opinion, it is important to find a balance when it comes to using smartphones in the classroom. Instead of completely banning their use, teachers can set clear rules and guidelines for smartphone usage. For example, they can allow students to use their phones for educational purposes only and during designated times. This way, students can still benefit from the advantages that smartphones offer, while minimizing the potential negative impact on their academic performance.In conclusion, the impact of using smartphones in the classroom is a complex issue. While they have the potential to enhance learning and provide useful resources, they can also be a distraction and hinder academic progress. It is crucial for educators to find a middle ground and establish policies that promote responsible smartphone use in order to create a conducive learning environment for all students.。
