step into“__________________________”，例如：He_____________ the boat and said goodbye to us. 他登上船向我们道别。

The boy ____________his shoes and ran out of the room. 那个孩子穿上鞋从屋里跑出去。

区别put on, have on, wear, dress的用法：put on是“_____________”的意思，可用于穿衣服、穿鞋、戴帽子等，着重于穿戴的动作。

例如：________ more clothes, or you'll be cold. 我穿点衣服否则你会感冒的。

He ____________his hat and went out of the room. 他戴上帽子，走出了房间。

have on 与wear相同，表示穿戴的状态，意思是“穿着……”、“戴着……”，但have on 一般不用于进行时，而wear可以。

Lili is_________ a yellow dress today. 李莉今天穿着一件黄色连衣裙。

She always _______her red shoes_____.(wears her red shoes)她总是穿着一双红鞋。

dress用于“穿着”、“打扮”，表示动作。

可作及物动词和不及物动词，作“穿着”解时，只用于穿衣服，不用于穿鞋，戴帽子，戴手套等。

作及物动词时，它的宾语是人，不是衣服，即dress sb意思是“______________________________”。

例如：She is old enough to dress herself. 她长大了，可以自己穿衣服了。

The mother hurriedly dressed her son and went out.这位妈妈匆匆忙忙给她儿子穿上衣服就出去了。

另外be dressed in 表示状态，“穿着……衣服”She was dressed in white. 她穿着白色的衣服。

The two foreigners were both dressed in Chinese style clothes. 这两个外国人穿着中式衣服。

first jeans were made in 1850, in the California gold rush.第一批牛仔裤在1850年制成，那是在加利福尼亚淘金潮中。

the California gold rush 加利福尼亚淘金潮，句中的the California gold rush 指的是1848年1月24日在加利福尼亚的萨特磨房发现了黄金，次年就有8万名梦想发财致富的冒险家迅速涌往西海岸，加入淘金热潮。

man named Levi Strauss realized that the gold miners' normal trousers wore out too quickly.一个名叫李·施特劳斯的人了解到淘金者穿的普通裤子很快就穿坏了。

a man named Levi Strauss 一个名叫“李·施特劳斯的人”。

named Levi Strauss是过去分词短语作___________，修饰man，相当于who was named Levi Strauss。

又如：Do you know a girl _________Yang Mei? 你认识一个名叫杨梅的女孩吗？再课本第四自然段中：……the rivet used to strengthen the jeans in the crouch got too hot and made them very uncomfortable.其中used to strengthen the jeans in the crouch也是过去分词短语做后置定语，修饰the rivet。

wear out作“______________________________”解，又如：Children _________their shoes very quickly.小孩子很快就把鞋穿坏了。

I have _______my must get another.我已经把衣服穿坏了，必须买一件。

My socks have_________. 我的袜子穿坏了。

The old clock finally_________. 最后这只旧钟用坏了。

had bought some strong canvas, intending to make it into tents and wagon covers.施特劳斯买了一些结实的帆布，打算用来做帐篷和车篷。

intend to do sth 意思是“_______________________”，又如：----What do you intend to do today? 你今天打算做什么？----I_______________ your school. 我打算去参观你们学校。

I've make a mistake, though I didn't intend to. 我犯了一个错误，尽管不是存心要犯的。

make A into B“___________________”，又如：We make the wood into a table. 我们把这些木料制成了一张桌子。

She make the material into a dress. 她把那块料子做成了一件女外衣。

注意make A out of B的意思是“用B原料制成___________________________”，其被动结构 A is made out of B表示“A是用B为原料制成的”。

如本课中的：…he made some trousers out of it… ……他用这些帆布制成裤子。

又如：The boy make a boat out of wood.(The boat was made out of wood.)那个男孩用木头做了一只小船。

上述make out of 短语动词也可用make of 来代替，其意思相同。

被动式是A is made of B。

例如：The table is made of wood. 桌子是用木头做的。
