一、默写单词。

父或母擦,洗烧,煮瓢虫扫地忙碌种植洗碗花园,果园甜的。

整理床铺害虫走开。

二、词组。走了如此甜。

三、语法解析:

现在进行时。

一、现在进行时的构成:由"be动词+ v-ing"构成。(v-ing表示在动词后面加上ing)

现在进行时常用以下几种情况:

1.当句子中有now时,常表示动作正在进行,这时要用现在进行时。如:theyare playing basketball now.现在他们正在打篮球。

2.以look, listen开头的句子,提示我们动作正在进行,这时要用现在进行时。如:

listen!she is singing an english song.听,她正在唱英语歌。

二、现在进行时的变化。

肯定句式:主语+ be( am, is, are)+ v-ing +其它。 am doing my is washing his clothes.

you are flying a kite.

否定句式:主语+ be(am, is, are) +not + v-ing +其它。 i am not doing my is not washing his are not flying a kite.

一般疑问句:be(am, is, are) +主语+ v-ing +其它? are you doing your homework?

is he washing his clothes?am i flying a kite?

特殊疑问句:疑问词+ be(am, is, are)+主语+ v-ing +其它? what are you doing in the house?

where is he going?

when is she doing her homework?

三、动词的ing形式的变化。

1)一般情况在动词原形后直接加-ing

go---going,stand---standing,cook---cooking,do---doing2)以e结尾的动词,要去掉e +

3)重读闭音节动词,要双写最后一个字母,再加ing(所谓“重读闭音节”:从动词的末尾开始寻找,如果倒数第二个字母是元音字母,并且元音字母两边的字母没有组合音,没有变音,都独自发音,这样的动词都必须,双写后,再加上ing

get- getting,put---putting,run—running, begin---beginning 这个动词有ea组合音,所以不能双写。

study---studying这个动词倒数第二个字母不是元音字母,不能双写4)以-ie结尾的动词,把ie变成y,再加。
