1、Unit 4 Then and nowPeriod 5开心回顾一、变被动语态的口诀被动语态强调“宾”，用 be加上“过去分”。“be”要随着主语变，人称时态要弄准。“行为对象”作主语，逻辑主语“by”来引。原句若是双宾语，一变“主”来一保“宾”。“间宾”要把主语变，原来“直宾”还是“宾”。“直宾”要把主语变，“间宾”前加“to”最称心。唯有原“宾”是“复合”，只有变宾要当心。原句“宾补”变“主补”，位置不必挪寸分。情态动词变“被动”，情态加be加过分。如若“情态”后带to，变后有to才弄准。“短语动词”变“被动”，相当“及物”莫疑心。不过其后“介”或“副”，变后还得要承认。二、写出下列类型的英
2、语单词。（每项至少写出两个）1.球类运动 2.形容词比较级 3.体育运动 4.农场动物 【答案】1. badminton football basketball table tennis volleyball2. thinner heavier bigger younger3. ice-skate go cycling race 4. horse cow sheep duck【解析】1.主要考查学生对各种球类运动名称的掌握和理解运用情况。2.考查学生对形容词比较级的变形规则的掌握，一般情况在单词末尾加er ，但是：（1）重读单音节要双写最后一个辅音字母加er ，例如：bigbigger（2）
3、以y 为结尾的变y为i + er，例如：happy happier（3）以字母e为结尾的直接+r。以上为常见的规则情况，还有特殊及多音节词等，会在以后专项学习。3.主要考查学生对体育运动词汇的掌握和理解运用情况。4.复习对动物名称词汇的掌握及分类情况。【难度】一般三写出下列动词的过去式。1.think 2.can 3.have 4.am 5.do 【答案】1.thought 2.could 3.had 4.was 5.did【解析】复习巩固常用词汇的一般过去式。来源:学科网课前导学一、教学版块Read and write二、词汇全解重点词汇1. race n. 赛跑【发音】字母a在单词中发/e
4、i/音。【中文释义】比赛，竞赛，竞争的意思。race还有另外一个意思，表示“人种，种族”。【短语】the space race 太空竞赛，run a 400-metre race 400米赛跑。【综合运用】I had a race with my classmates yesterday. 我昨天和同学们进行了一次比赛。He won the swimming race yesterday.他在昨天的游泳比赛中获胜了。2. nothing pron. 没有什么【发音】字母th在单词中发/音。【巧记】no（没有）+ thing（东西，事物） = nothing（没有什么）【综合运用】Compare
5、 with your health, nothing is important. 和你的健康比起来，没有什么东西更重要。Nothing is impossible.没有什么是不可能。3. trip v. 绊倒【发音】字母tr在单词中发/tr/音。【中文释义】“绊倒，摔跤”的意思；trip还有另外一个意思，“旅程，行程”，为名词，例如：a round trip 往返的行程。【综合运用】He tripped and hurt his leg. 他绊了一跤，把腿伤着了。Have a good trip.旅途愉快。4. dream n. 梦【发音】字母dr在单词中发/dr/音。【中文释义】梦，梦想。d
6、ream还可以用作动词，表示“梦想，梦见”的意思。【综合运用】I had a beautiful dream yesterday. 我昨天做了一个美丽的梦。Keep a dream in your mind, you must have a wonderful future.心中常驻梦想，必有精彩未来。5. woke v. 醒【发音】字母o在单词中发/u/音。【中文释义】醒，wake的过去式，反义词为sleep（过去式为slept）。【综合运用】I woke up at six oclock this morning. 我今天早上六点钟醒的。My mother woke me up yeste
7、rday morning.昨天早上我妈妈叫醒了我。6. make v. 使得【发音】字母a在单词中发/ei/音。【中文释义】使役动词，“使得怎么样”。 这个短语是由make sb. to do sth. 省略to得来的。make, let等使役动词，以及感官动词后面接动词不定式作宾语补足语时都要省略to。【综合运用】We made the little boy laugh.我们让这个小男孩笑了。The wind makes the kite fly.风使风筝飞起来。三、句型突破能够使用一般过去式叙述和表达曾经的梦境【课文应用】Wu Yifan had a race with father an

9、去式 + 其它成份。【重点解析】1.在一般过去式的句子中，谓语动词要用相应的过去式。2.nothing一词为不定代词，担当主语时，被看作单数形式，be动词要用is（过去式was），类似的代词还有no one，nobody 等。【生活实例】Li Ming played football with his friends. There were many students on the playground. His friend all played very well but Li Ming could not. “I could play well before,” he thought.
10、“Why cant I play well now?”李明和他的朋友们踢了一场足球。（当时）操场上有很多学生，他的朋友们都踢得很棒，但是李明发挥不好。“我以前踢得很好，”他想，“现在我为什么踢不好呢？”作业设计一、读一读，翻译下列短语。1. had a race 2. win the race 3. woke up 4. last night 5. run very fast 6. an interesting dream 【答案】 1.进行了一场竞赛2.赢得比赛3.醒来了4.昨天夜里5.跑得非常快6.一个有趣的梦【解析】本题考查学生对课文中出现的短语的掌握情况，尤其是有些动词的过去式的形式，
