4. 此行无错。

3. 删去about。此处consider为及物动词， 直接接宾语。

2. warm改为warmth。warm为形容词， 在its后应用名词warmth作feel的宾语。

1. depend后加on。此处depend为不及物动词， 应与on连用， 表示“依赖， 依靠”。

10. discuss改为discussed。非谓语动词错误。此处动词discuss与其逻辑主语subjects应为被动关系，故用discussed作定语。

9. are改为is。主谓一致错误。主语time为不可数名词， 谓语应用单数形式。

8. listen前为to。have time to do sth.意为“有时间做某事”。

7. going改为go。be ready to do sth.为固定短语， 意为“准备做某事”。

6. 删去because后面的of。because后面应接一个句子； 而because of后面应接名词、 代词、 动名词。

5. informations改为information。information为不可数名词。
