And remember, “Old habits 9______hard.” So start exercising 10______it’s too late.
学习任务三
1. Although many students like to watch sports, game shows are the most popular.
although是连词，意为“虽然、尽管”，引导让步状语从句，可以与though互换，但不能与but同时出现在一个句子中。也就是说，在同一个句子中，有although就没有but，反之亦然。
e.g. Although He is ill, he goes on working.=He is ill, but he goes on working.
2. It’s good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise. 通过上网和看游戏类节目来放松没错，但我们认为最好的放松方式还是通过锻炼。此句是“It’s + adj. (for sb.) to do sth.（对某人来说）做某事是……的”，it作形式主语，真正的主语是后面的动词不定式。e.g. It’s important(for us) to learn English well.
3. be afraid害怕 be afraid to do sth.害怕做某事 be afraid of doing sth.害怕做某事
be afraid of sb./sth. 害怕某人/某物 be afraid+that从句: 担心……,恐怕……
4. worry about=be worried about 担心、担忧
5. a 16-year-old student一个16岁的学生
