课件16张PPT。Unit 4 I used to be afraid of the dark.Section A（1a-2d）Lu Han课前预习课前预习Ma Yun课前预习Li Yifeng课前预习课文解析1.He used to be really short. 他过去很矮。
“used to +动词原形” 表示过去的习惯或过去经常反复发生的动作或状态 (现在已经不再存在)。
例: I used to be afraid of the dark.我过去怕黑。
He used to like playing games.他过去喜欢玩游戏。 日常口语中,句型转换常用助动词did，例如:
You used to be short. Did you use to be short? He used to play tennis. Did he use to play tennis?知识拓展 be (get) used to中的to是个介词，和used to不同。该词组的含义是“习惯于……”。巧合的是，在汉语中，这个“于”也是个介词，所以to后面不能接动词原形，而要接名词或v-ing形式。例：They are used to the hard work here now. 他们现在习惯于这里的艰苦工作了。I’m used to dealing with matters of this kind. 我习惯于处理这类事情。知识拓展 “be used to do ”被用来做某事。例：Wood is used to make paper . 木头被用来造纸。 Computers are used to do many things for people .电脑是用来为人们做许多事情。2a Listen and check (√) the words you hear.√____ friendly ____ outgoing ____ serious

She was always silent in class.
在课堂上她总是很沉默。
silent作形容词，意为“不说话的；沉默的”，其名词形式为silence （沉默；寂静）
例：She was silent when her mother asked her questions.
她妈妈问她问题时她沉默不语。1) Silent 的副词形式是silently (默默的；静静的)。
例： He went in to the classroom and sat down silently.
他走进教室静静地坐下来。
2) keep silent意为“保持安静”
例： Please keep silent in public places.
在公共场合下请保持安静。课文解析3. She still play the piano from time to time.
她仍然时常弹钢琴。
(1) still 副词，意为“仍然”，用来说明某人或某物没有变化。still 在句中通常放在实义动词前, 助动词、情态动词、连系动词后面。
例：The woman still lives in shanghai.这个女士仍然住在上海。
He is still in the classroom.他仍然在教室里。
(2) from time to time 意为“时常；有时”相当于sometimes /at times.
例： She goes to the movies from time to time.
她有时去看电影。课文解析such与so 辨析：
such为形容词，意为“这（那）样的；主要修饰名词；
so是副词，意为“这（那）么；如此地”，主要修饰形容词、副词和分词。4. This party is such a great idea!
这个派对真是个好主意！
He used to be so shy and quiet.
他过去非常害羞安静。课文解析 当名词前有many，much，few或little等词修饰时，要用so而不用such。例： There are so many / few people in the hall.
大厅有这么多/这么少的人。
You have so much / little homework today.
你今天有这么多/这么少的作业。课文解析“such + a / an +形容词+可数名词单数形式”相当于“so +形容词+a / an +可数名词单数形式”，表示“如此……的一个……”。例： She is such a lovely girl. = She is so lovely a girl.
她是这个如此可爱的女孩。知识拓展
