八年级英语牛津版8B Unit 3重点学案.I. 重点句型讲解1. You need to exercise and keep fit．你需要锻炼和保持健康。

exercise在这句话中是动词“锻炼”“运动”“训练”的意思，但它也可以作名词。

当它解释为运动时是不可数名词，而解释为“练习，操练”时则是可数的,如：Mary is fat. She doesn't exercise enough．(动词，锻炼) 玛丽有点胖，她锻炼的不够多。

Doing morning exercises is good for your health．(可数名词，做早操) 做早操对你的身体有好处。

You‟d better take more exercise to keep healthy．(不可数名词，运动) 你最好多做运动以保持健康。

keep fit是一个习惯用语，意思是“保持健康”，fit在句中是形容词，意思是“健康的”, 如：I hope you are keeping fit．我希望你能保持健康。

2. Kitty’ s teacher Mr. Wu invited me to join their schoo l trip to the World Park．基蒂的老师吴先生邀请我参加由他们学校组织的到世界公园的旅游。

invite是动词，意思是“邀请”，invite sb．to do sth．“邀请某人做某事”。

invite sb．to sp．“邀请某人去某地”, 如：We invited him to our house for a drink．我们邀请他到我们家喝酒。

He invited me to have coffee，tonight．他邀请我今晚去喝咖啡。

3. It was a great da y but we didn’t enjoy it at the beginning．这是愉快的一天，但一开始我们并不开心。
