升高一第一讲时态

一时刻开始，并继续下去的动作。常用来表示礼貌的询问、请求等。例如： 1)This time next day they will be sitting in the cinema. 2)What will you be doing at six tomorrow evening? 练习——用所给动词的适当形式填空.

1.Look! The cat____________(run)up the tree. 2.The twins__________(have)breakfast.

3.----__ _he ________(clean) the blackboard? ----No,he isn’t.

4.Tom__________(play)the piano in the room.Please ask him to come here. 5.Listen! They____________(sing)in the classroom. 现在分词变化规则：

当我们说某人正在做什么事时，动词要使用分词形式，不能用原形，构成如下：

一）一般在后加ing。如：spell-spelling, sing-singing, see-seeing, train-training, play-playing, hurry-hurrying, watch-watching, go-going, do-doing

二）以不发音e的结尾的去掉e再加ing。如：dance-dancing, wake-waking, take-taking, practice-practicing, write-writing, have-having

三）以重读闭音节结尾且一个元音字母＋一个辅音字母（注意除开字母组合如show –showing, draw-drawing）要双写最后的辅音字母再加ing。如：put-putting, run-running, get-getting, let-letting, begin-beginning

四）以ie结尾的变ie为y再加ing。如：tie-tying系 die-dying死 lie-lying 位于

闭音节和开音节

首先这个音节必须是重读的，而且只有一个元音（指音标），如map,bed,sit, hot, cut.；一般情况下重读闭音节都是单音节词比较多，构成 辅元辅 的结构（可以观察一下音标），但也有个别双音节词，如forget其中的get就是重读闭节 开音节:以一个 元音字母结尾的重读音节称为开音节(或称绝对开音节).例如:be, no, hi, we, go, so等.包含一个元音字母的重读音节中,在元音字母后面有一个辅音字母(r除外),还有一个不发音的字母e,这种重读音节也叫开音节(或称相对开音节). 例如:name, time, bike, cake, nose等.不论是绝对开音节还是相对开音节,其元音字母读它们本身的发音,即a[ei] e[i:] i[ai] o u[ju:]. 开音节：下面两种音节成为开音节

a) 指发音的元音字母结尾的音节，如：no [n, he[hi:];

b) 以\元音字母+辅音字母（r除外）+不发音的e\结尾的音节，如: face [feis].

(2) He liked playing basketball before. (改为一般疑问句)
