Question：老师，您上次说介词和连词讲完了，今天开始学习什么呢！ Answer：学习关系从句，也是我们经常说到的定语从句。今天学习关系从句（1）：who, which, that引导的关系从句 who, which, that引导的关系从句 Reading： Corn was brought from America by Christopher Columbus in the 1490s. Corn is a useful plant that can be eaten by both people and animals. In the 17th century corn was grown a lot in Tibet and Sichaun in China. At that time the land along the Changjiang River was becoming very crowded. Farmers had to move into hills where they couldn’t grow rice. They needed a plant which didn’t need as much water as rice. Luckily they were able to grow this new corn. Corn was not the only food that was taken to Europe. In 1519 another traveler who went to America from Europe discovered the tomato. I．Who/that 代替人 Which/that 代替事 1 In 1519 another traveler who went to America from Europe discovered the tomato. who went to America from Europe 是一个关系从句，关系从句用来限定一个人或一件事。who went to America from Europe限定another traveler。 2 关系代词who用来代替人,关系代词which 用来代替事。 …another traveler who went to America from Europe discovered the tomato. They needed a plant which didn’t need as much water as rice. 3 that常常可以代替 who , which. Corn is a useful plant that(=which) can be eaten by both people and animals. In 1519 another traveler who(可以用that) went to America from Europe discovered the tomato. 对于人Who比 that使用更频繁。 对于事That比 which 使用更频繁。 注： 有时只能用Who 和 which 不能用that 。 有时只能用that如：Corn was not the only food that was taken to Europe. 当先行词被序数词、形容词最高级、only等词修饰时；当先行词是不定代词时；或当先行词既指人又指物时，只能用that。如： This is the second time that I have spoken in public. Later we talked about the school and the teachers that we could remember. 小练习. 用关系代词填空： 1 Early European travelers to China took back their own countries the seeds of fruit trees ____they had not seen before. 2 Today, fruit trees ____once grew only in China can now be found in many parts of the world. 3 This is the best film____ I have ever seen. 上期答案： 1 Since/As air communications are in English, airline pilots must learn it. 或Air communications are in English, so airline pilots must learn it. 2 Many people in Europe want to work abroad, so they have to learn a foreign language. 3 Many British and American people won’t learn foreign languages because they think everybody should speak English. |
