教学建议三
过去将来时的教学建议
本单元的语法重点是过去将来时。过去将来时是表示对过去某一时间来说将要发生的动作或状况。通常用would或was/were going to+动词原形来表示。如:He said he would go to his hometown for the Spring Festival. 他说他将回家乡去过春节。
They told me that they would visit China the next week.他们告诉我他们下星期将访问中国。
She said that she was going to do some shopping the next day. 她说她第二天将去买东西。
过去将来时通常在以下几种情况下使用。
1.主句为过去时,在宾语从句中表示将来的事情用过去将来时。如第51课中第3部分
Make sentences中的句子:
I didn’t know that they would be able to buy another car.
My uncle never knew that a car would cost more than a house.

意思是:“我当时不知道他们会买另一辆新车。” “我叔叔当时不知道一辆汽车会比一幢房子贵。”
2.在叙述过去的事情时,在当时看来将要发生的事。如:
She was our new teacher and she would be 30 years old that year. We all liked her very much and we were going to have a party for her birthday. 她那时是我们的新老师。她那一年就到30岁了。我们非常喜欢她,打算为她举办一次生日聚会。
过去将来时还有其他一些用法,教师不必讲得太多,因为这个时态在初中阶段仅要求理
解。可以指导学生把一些句子改为过去将来时,如:
The small children did not know who filled their stockings.
The small children did not know who would fill their stockings.小孩子们不知道谁将往他们的袜子里塞东西。
They didn't know what would be in their stockings.小孩子们不知道谁将往他们的袜子里塞东西。
下面一组句子可供教师们作补充练习:
I didn't know that they would be all there. 我不知道他们都会去那儿。
They didn't know whether we would win or not. 他们不知道我们是否会取胜。
He told Jim not to worry. He would take care of Polly. 他告诉吉姆不必担心,他会照看波利的。
He said he was going to send me a Christmas card. 他说他将会给我寄一张圣诞卡。
I couldn't decide which school I would go to. 我当时无法决定上哪一所学校。
数字读法的教学建议
第49课重点训练大数字的读法,除了要向学生讲清楚读多位数字要注意的规则外,还要引导学生通过练习逐渐熟练地掌握,不要急于求成。本单元话题是世界人口问题,为训练多位数字的读法提供了真实、自然的语言情景。
第49课第一、二部分主要是教学多位数字的引入和练习阶段,可用卡片或把数字写在黑板上的方法教学。教师应引导学生总结读数字的规律。
