3.Key points
a. 词汇包：
by the time 到……时候
【备课例句】
by the time作连词引导时间状语从句，当从句用一般过去时，主句用过去完成时；当从句用一般现在时，主句用一般将来时或将来完成时。
By the time he was te ( http: / / www.21cnjy.com )n, Tom built a chemistry lab himself. 等到了十岁的时候，汤姆自己建了一个化学实验室。
I’ll be in bed by the time you get home. 你到家时，我已经上床睡觉了。
【课堂变式】
—By the time I was five, I ____English. —Really A. had started learning B. have started learning C. started to learn D. started learning 【解析】by the time所引导的从句是一般过去时，其主句要用过去完成时。正确答案是A。
b. 句式包：
1.By the time ( http: / / www.21cnjy.com ) I got outside, the bus had already left.当我出来的时候，公共汽车已经走了。
本句是by the time引导的时间 ( http: / / www.21cnjy.com )状语从句，从句是I got up，是一般过去时。主句the bus had already left是过去完成时。过去完成时表示在过去某个时间之前已经发生的动作或一直延续的动作或状态。它表示的动作所发生的时间是“过去的过去”，常用“助动词had+过去分词”构成。常与过去完成时连用的时间状语有：by(the end of)+过去的时间，for+段时间，since+点时间，when引导的时间状语从句(从句中谓语动词用过去时)等。
【备课例句】
By the end of the ( http: / / www.21cnjy.com ) match, they had kicked two goals and we had kicked four.
到比赛结束时，他们已踢进两个球，我们进了四个球。”
By the time she g ( http: / / www.21cnjy.com )ot up, her brother had already gone into the bathroom.
在她起床之前，她的弟弟已经进了盥洗室。
【横向辐射】过去完成时与现在完成时的区别
过去完成时与现在完成时的主要区别是时间的参照点不 ( http: / / www.21cnjy.com )同：过去完成时的时间参照点是某个“过去的”时间；现在完成时的时间参照点是“现在”。因此现在完成时中的很多规则，也适用于过去完成时。【例句】When I got to ( http: / / www.21cnjy.com ) the cinema, the film had been on for five minutes.当我到达电影院时，电影已演了五分钟了。(got是一个过去的“时间点”，电影“开始”在我“到达”之前，是“过去的过去”。因为for five minutes为延续一段的时间状语，应用可延续的系表结构be on的过去完成时形式。）【温馨提示】过去完成时是 ( http: / / www.21cnjy.com )一个相对的时态，表示的是“过去的过去”，只有在和过去某时或某动作相比较时才用到它，因此当原句中若找不到一个“过去的时间”作为参照点时，是不能用过去完成时的。【例句】He got to the railway station and suddenly realized that he had forgotten to bring his ticket.他到了火车站后忽然意识到他竟忘记带车票了。（“忘记”这一动作在“意识到”这一动作之前。）
【课堂变式】
1.—Why didn’t you go to the movie yesterday —Because I ____it before. A. had watched B. have seen C. have watched D. had seen 【解析】“看电影”要用动词see，所以 ( http: / / www.21cnjy.com )可先排除Ａ和Ｃ。再由yesterday可知答话者在昨天之前就已看过这部电影，即“过去的过去”，要用过去完成时。正确答案是D。2.By the end of last year, we ____ about 2000 English words. A. were learning B. have learnt C. learnt D. had learnt 【解析】由时间状语By the end of last year可知应用过去完成时，即“had+过去分词”。正确答案是D。3.Since 2000, Nanchang has become a new city. Everything ____. A. is changed B. was changed C. has changed D. had changed 【解析】由上文中的Since 2000可知过去的动作change对现在产生了结果，即一切发生了变化，应用现在完成时。正确答案是C。

2. alive adj. 活着的；有生气的；
alive, living 与live
1. alive 主要用作表语（有时可 ( http: / / www.21cnjy.com )用作后置定语，但不用作前置定语），可用于人或动物。如：He must be still alive. 他一定还活着。
注：若 alive 本身有修饰 ( http: / / www.21cnjy.com )语，则也可用作前置定语。如：He is a really alive student. 他的确是一个十分活跃的学生。
2. living 可用作表语或定语，可用于人或物。如：
Are your grandparents still living？ 你的祖父母还健在吗？
alive 和 living 表示“活着的”，两者含义很接近，只要句法适合，有时可互换。如：谁是当代最伟大的诗人？
正：Who is the greatest living poet？
正：Who is the greatest poet alive？
若需严格区分，两者仍有差别：livin ( http: / / www.21cnjy.com )g 通常是客观描述某人“尚在人间”或“健在”，而 alive 则主要指生与死的“界限”。如：He was still alive when I reached the hospital. 当我赶到医院时他还活着。
3. live 通常只用作定语（前置），可用于动物或植物，但一般不用于人。如：
He bought some live fish. 他买了几条活鱼。
Only a few live trees were left after the fire. 火灾之后只剩下几棵树还活着
【课堂变式】
Don’t be too sad, we should feel lucky to be _____(live).【解析】考查形容词，由句意可知。我们应当感到幸运我们活着，be alive表示活着的状态。故填alive

My lucky day

When I woke ( http: / / www.21cnjy.com )up that morning, I brushed my teeth, washed my face, then I read English for half an hour. It was time to eat my breakfast. My little brother gave me a piece of Oreo. I was very glad to eat it first. Then I felt strange. It tasted special. What was it I looked at my little brother. He laughed loudly and said nothing.
Later that day, I ( http: / / www.21cnjy.com ) knew he put toothpaste (牙膏) into the Oreo. I couldn’t believe I was fooled by him. I brushed my teeth again. After that, my brother gave me a box of Oreo, and said “Happy April Fool’s Day.”
Finally I was happy to get these delicious biscuits.
I think I had a happy and lucky day.
What a lucky day!
