()4. the best way to relax is through exercise.    through 介词，课文中意为“以，凭借”    e.g. He found the job through an advertisement in the newspaper.        他通过报纸上的一个广告找到这份工作。拓展 through还有“穿过”之意。表示“从内部穿过”。e.g. They went through the forest yesterday.    昨天他们穿过了森林。5. Exercise such as playing sports is fun    such as意为“像这样”，表示列举。    结构常为：名词+such as+ 例子    e.g. She likes animals such as rabbits and birds.       她喜欢像兔子、小鸟这样的小动物。注意：其后面不可列举出所有的事物。如：我了解四种语言，例如英语、汉语。I know four languages, such as, English and Chinese.

Old habits die hard.  旧习难改。  这是英语中的一句谚语，表示习惯一旦养成，并非朝夕即可改变，多用来  描述人们一时难以改变的固有观念及做法。e.g. Its the age of new technology, but my grandpa still goes everywhere with his old radio. Old habits die hard, you see.    现在都已经是新技术时代了，可我爷爷仍然到哪儿都带着他的收音机。你瞧，老习惯可真难改呀。7. So start exercising before its too late!  its too late  为时太晚；来不及了  e.g. Now you know youre wrong, but its too late.     现在你知道你错了，但是已经太晚了。 its too late及before共同组成从句，表示“不要等到为时已晚；不要等到来不及的时候；趁着还来得及 ”。e.g. You should work harder before its too late to catch up.   你应当更加用功，别等到为时过晚而赶不上了。（你现在用功还赶得上。）Work on 2e:1.
