【教学内容】
考点1 So & Neither/Nor 倒装
-I really hate going to a place like that. -So do I.
-What’s more, the pollution in developing countries is growing faster. –So it is.
So / Neither / Nor + be / 情态动词 / 助动词 + 另一个主语 （某某也一样 / 也不这样）
此为倒装句，表示前面提到的肯定/否定情况也同样适合另外一个主体。
【注意】此句所用的时态要与前句的时态相同，“be / 情态动词 / 助动词”的形式要与后面的主语一
致。
eg. (1). --- I really hate to go to such a place.
--- So do I. (我也是)
(2). --- Tina isn’t a lazy girl.
--- Neither / Nor am I. (我也不是)
拓展：So + 主语 + be / 情态动词 / 助动词 （……的确如此）
此句表赞同，主语与上文指同一人或物。
eg. --- It was cold yesterday.
--- So it was. (它确实是这样)

“Thanks for our government. Thanks for providing us with such a good training program. The training program will help us live well. I will study hard and learn different skills. After that I can 16 my family difficulties and do good to others.” a learner on the job training program said, feeling 17 .
The learner’s father is disabled, and his mother is 18 in bed. The family is very poor. So he has to find a job to make money. The learner graduated from high school and didn’t have the 19 to go to the college. The job training program can help him to learn the skills that he’ll need in the work place.
The story makes me think of another 20 . It goes like this: Long long ago, there was a man who liked fishing a lot, and he was 21 to catch a lot of fish every day. He was a kind-hearted man, he always 22 his fish with his neighbors because they didn’t know how to fish. One day, he thought that it would be great if he taught them how to fish. So he called them together to show them how to fish. Everyone was happy as they could 23 the fish they caught by themselves.
Now, there are still many poor people in the world. But it’s not good if we give only 24 to them. Instead, we should give them a chance to learn new skills. Therefore, technical training is very important to people in need and they will learn the skills to 25 money. People can learn lots of useful things in the training program and what they learn can help them find jobs.
