别担心，慢慢来。等你第一次比赛，我们去给你加油。

Bié dānxīn, mànmàn lái. Děng nǐ dì yī cì bǐsài, wǒmen qù gěi nǐ jiāyóu.

Don't worry, take it slowly. When you have your first game, we'll come cheer for you.

先别跑。再休息两天，可以慢慢散步。等咳嗽好了，再增加运动。

Xiān bié pǎo. Zài xiūxi liǎng tiān, kěyǐ mànmàn sànbù. Děng késou hǎo le, zài zēngjiā yùndòng.

Don't run yet. Rest for two more days and take gentle walks. Once the cough is gone, increase your exercise.

参加比赛的同学请穿运动鞋，并带好学生证。

Cānjiā bǐsài de tóngxué qǐng chuān yùndòngxié, bìng dài hǎo xuéshēngzhèng.

Students taking part in events should wear sports shoes and bring their student ID.

我建议先帮助他建立整理书包的习惯，不需要因为这两次作业增加很多练习。

I suggest first helping him build the habit of organizing his schoolbag. There is no need to add lots of extra exercises because of these two assignments.

对。共同点可能是家人见面、出去参加活动，但具体怎么过还是要看地方和家庭。

Duì. Gòngtóngdiǎn kěnéng shì jiārén jiànmiàn, chūqu cānjiā huódòng, dàn jùtǐ zěnme guò háishi yào kàn dìfang hé jiātíng.

Right. Common points may include family members meeting or going out for activities, but the details depend on the place and the family.
