二.并列连词

⑶ Not only the students but also the teacher likes this movie.
（不但学生们，连老师也喜欢这部电影。注：not only...but also连接的并列句中，
谓语动词的单复数遵循 “就近原则”， 即与 but also 后的主语保持一致。）

Either he or you are right. 要么他对，要么你对。
4.表示结果的并列连词主要有：so（所以）

Task15 Read and underline.
What makes a great invention? It is state-of-the-art technology. It doesn’t just offer one solution to one problem. It either opens up new opportunities, or leads to new choices in life. A great invention is great for it may cause changes in more than one field. Like it or not, great inventions have changed our lives and the way things work, so we should embrace them. We know life is not perfect, but it will become better and better as more inventions are made.
