三、课文主要语言点

Our dog Rex used to sit outside our front gate and bark.	1）Rex用作our dog的同位语。此处用逗号前后隔开是为了起强调作用，也可以省略前后的逗号。 2）used to do，过去习惯做某事。注意对比be used to doing（现在习惯做某事）和be used to do（被用来做某事）。 3）front gate，前门。 4）注意and后面只有一个词bark（狗叫），这与前面的较长的句子成分形成鲜明的长短对比，从而使得bark一词得到了凸显，起到了很好的强调作用，进而把这条狗总是叫的特点表现出来了。
Every time he wanted to come into the garden he would bark until someone opened the gate.	1）注意every time引导的时间状语从句，time后面不要加when，而是every time sb./sth. do/does/did sth.。 2）he would bark中的would do表达的是过去的习惯。 3）注意until不一定要跟not连用。
As the neighbours complained of the noise my husband spent weeks training him to press his paw on the latch to let himself in.	1）注意本句话中的as表示“因为；由于”，引导的是原因状语从句。 2）注意neighbour的拼写，美式拼法为neighbor。 3）complain of，抱怨、投诉。如果要表达向某人抱怨，则用：complain of sth. to sb.。 4）注意spend time doing的用法，表示花时间做某事。 5）train sb./sth. to do，训练某人或某物做某事。 6）press，按、压。 7）let sb. in，放某人进来。
Rex soon became an expert at opening the gate.	become an expert at，变得擅长做某事。相当于become skillful at。
However when I was going out shopping last week I noticed him in the garden near the gate.	1）注意句中的when可以替换为while。 2）go out shopping，出门购物。 3）notice sb. somewhere，注意到某人在某处。
This time he was barking so that someone would let him out!	1）注意句中的so that引导的是目的状语从句。注意与结果状语从句so...that...的区别——目的状语从句中的谓语动词大多会加上情态动词can/could/would等。 2）let sb. out，让某人出去。
Since then he has developed another bad habit. As soon as he opens the gate from the outside he comes into the garden and waits until the gate shuts. Then he sits and barks until someone lets him out. After this he immediately lets himself in and begins barking again.	1）注意第二句、第三句和第四句是对第一句中another bad habit的解释说明。 2）develop a habit，养成一个习惯。 3）shut，关闭。相当于close。 4）begin doing，开始做某事。
Yesterday my husband removed the gate and Rex got so annoyed we have not seen him since.	1）remove，移除、删除。 2）注意句中的so annoyed后面省略了that，引导的是结果状语从句。 3）annoyed，恼火的。 4）haven't done...since，从此没有...。
