三、重点句型
1．If we learn to welcome change and appreciate what is new and different, we will be well-
prepared for whatever the future may have in store. 如果我们学会迎接变化, 学会欣赏新的不同的东西, 我们就能有准备地迎接未来给我们带来的一切
what is new and different是名词性从句, 在句中作宾语. 如:
He is so young that he cannot tell what is right and what is wrong.
be well-prepared for “为……作好准备”, 通常表示一种状态.
We are well-prepared for the coming examination.
2．For example, if you use a telephone that transforms a person’s voice into ones or zeroes, as a digital phone does, you still think that the voice you hear is “real”,
don’t you? 例如, 如果你使用一部把人的声音转换成数字的电话, 就像数字电话那样, 你仍然会认为你听到的声音是真实的, 是吗?
as a digital phone does “就像数字电话那样”, 此时as引出的是一方式状语从句, 从句还可以用倒装.
