此句为省略句，完整的句子是：Is there anything wrong?

3. What seems to be the problem? 到底是怎么回事?
4. She is crying in the bathroom because she did badly in the English exam.因为考不好，她在洗手间里哭呢。
badly为副词，修饰动词的副词通常放在被修饰的动词之后。如：listen carefully, read quickly等。do badly in 在……方面做得不好，与do well in意思相反。

He did very well in English when he was young. 他小时候就很擅长英语。
5. She is very strict with herself. 她对自己要求很严格。

e.g. She left for Shangqiu alone. 她独自去了商丘。(状语)
Jim’s parents both went shopping. So he is alone at home.吉姆的父母都去买东西了。因此只有他自己在家。(表语)
B. lonely形容词，常在句中作表语、定语，侧重人的心理。
e.g. There is a lonely room on the side of the hill. 山坡上有一间孤零零的房子。(定语)
The old man seldom speaks to others, but he never feels lonely.那老人很少与其他人说话，但他从不感到寂寞。(表语)
2)不定式短语to talk with作后置定语修饰friends。
e.g. Mary, I can’t go there with you, because I have a lot of homework to do.
玛丽，我不能和你去那儿，因为我有许多家庭作业要做。
7. I think I should have a talk with her.
have a talk with sb.和某人交谈，talk在这里是名词,这个短语相当于talk with sb.。
e.g. You should have a talk with your son to know what he is thinking about.
