1c-Make conversations
A: I don’t think sixteen-year-olds should be allowed to drive.
B: I agree. They aren’t serious enough.
A：我认为不应该允许16岁的青少年开车。
B：我同意，他们还不够认真。
否定前移：当主语是第一人称（I/we）并且是一般现在时，且主句谓语动词时用来表示想法、观点、信念、推测等心理活动的词时，其后的宾语从句若是否定句，否定词要前移到主句上。主句否定，弱化断言，更礼貌/含蓄；从句否定，显得更直接甚至突兀。
think, believe, suppose, imagine, reckon, guess, expect, figure, feel（“觉得/认为”意义）
- I don’t think he will come today.
- We don’t believe this plan is practical.
- I don’t suppose she knows the truth.
- I don’t imagine they will agree with us.
- We don’t expect the rain to stop soon.
I don’t think + sb. should be allowed to do sth. 我认为不应该允许某人做某事
- I don’t think students should be allowed to use mobile phones in class.
- I don’t think people should be allowed to smoke in public parks.
- I don’t think young kids should be allowed to watch violent movies.
- I don’t think visitors should be allowed to take photos in this museum.
enough的基本用法
(1) 修饰名词 enough + 名词 → “足够的” ；
(2) 修饰形容词/副词：形容词/副词 + enough → “足够……的 / ……得足够”；
为什么 enough 放在形容词/副词之后：固定语序现象，核心意思是“达到（形容词/副词所描述的）某种足够程度的”，后置的 enough 更靠近它所限定的 “结果或目的”（如 to swim, to win），使句子逻辑更连贯。
- I have enough money.
- He runs fast enough to win the race.
- The water is warm enough to swim.
2d-Role-play the conversation
Sandy: I’m really excited about seeing the famous paintings by Picasso.
Wu Lan: Me, too! I’m glad Mr. Smith chose the art museum for our school trip this year.
Sandy: I’m going to bring my new camera to take lots of photos!
Wu Lan: Oh, no. Mr. Smith says we must not take photos. It’s not allowed in the museum.
Sandy: That’s too bad! Do you think we may be allowed to take photos if we don’t use a flash?
Wu Lan: Hmm… I think they just want to protect the paintings. So if you don’t use a flash, then it may be OK.
Sandy: Yeah. I think we should be allowed to do that. I’ll bring my camera anyway.
参考译文
桑迪：我真的很期待能看到毕加索的那些名画。
吴兰：我也是！真高兴史密斯先生今年选了美术馆作为我们的学校旅行地点。
桑迪：我打算带上我的新相机，拍好多照片！
吴兰：哦，不行。史密斯先生说我们不允许拍照的。美术馆里不让拍。
桑迪：太糟糕了！那你觉得如果我们不用闪光灯的话，会不会被允许拍照呢？
吴兰：嗯…… 我觉得他们只是想保护这些画作。所以如果你不用闪光灯的话，或许是可以的。
桑迪：是啊。我觉得我们应该被允许那样做。不管怎样，我还是会带上相机的。
Key Words

Key Structures
口语中为了简洁自然，常会省略句子的 “冗余成分”，“depends which movie” 本质是 主句 + 宾语从句 的省略形式，完整表达应为：
It depends on which movie (it is/we are going to watch).
- “depend” 本身是 不及物动词（不能直接接宾语），必须搭配介词 “on/upon” 构成短语，才能接 “依赖 / 取决于的对象”
- Whether we go out depends on the weather.
- 完整句中的 “It depends on…” 用 “It” 作形式主语，是因为 “取决于……” 这个概念本身没有具体的 “主语”，用 “It” 填充主语位置，符合英语 “句子必须有主语” 的语法规则，属于 “形式主语的固定用法”。
