我喜欢春天和夏天，但是不喜欢冬天，因为冬天很冷，总是下雪。

Wǒ xǐhuān chūntiān hé xiàtiān, dànshì bù xǐhuān dōngtiān, yīnwèi dōngtiān hěn lěng, zǒngshì xiàxuě.

I like spring and summer; however, I don't like winter because winter is cold and always snows.

这个城市夏天不太热，很舒服。

Zhège chéngshì xiàtiān bú tài rè, hěn shūfu.

Summer in this city is not very hot; it’s very comfortable.

如果夏天有时间，我想去海边旅游。

Rúguǒ xiàtiān yǒu shíjiān, wǒ xiǎng qù hǎibiān lǚyóu.

If I have time in summer, I want to travel to the seaside.
