简单连词 (A1)

用 and 把一个想法和另一个类似的想法连起来。

and = 补充

Amina likes tea and coffee.
Hiroshi is kind and funny.
Sofia reads and writes every day.
Not "Amina likes tea coffee." — say "Amina likes tea and coffee.". and 就是把两个想法连在一起的词。
试一试: Amina likes music ___ books. She likes both. (and / but / or) 答案: and — 她两个都喜欢，是在补充另一个想法，所以用 and。"but" 会表示她喜欢一个不喜欢另一个；"or" 则是给出一个选择。

第二个想法和前面相反，或者出人意料，就用 but。

Hiroshi likes coffee but not tea.
The cafe is small but nice.
Sofia wants to go but she is tired.
Not "Hiroshi likes coffee and not tea." — say "Hiroshi likes coffee but not tea.". 两个想法是冲突的，所以用 but。"and" 只是把两个想法加在一起，并不能表现出冲突。
试一试: Mei likes cats ___ she doesn't like dogs. (but / and / because) 答案: but — 第二个想法和第一个正好相反，所以用 but。"and" 会表示两者是一致的，但这里一个是肯定一个是否定。

用 or 让对方在两样东西里选一个。

Tea or coffee?
We can walk or take the metro.
Is Amina at home or at school?
试一试: Waiter: Tea ___ coffee? Amina: Coffee, please. 补全服务员的问题。 (or / and / but) 答案: or — 你是二选一，不是两个都要，所以用 or。"and" 会表示你两个都想要，那就不是选择了。

用 because 说明原因，回答为什么会发生某事。

Sofia is happy because it's Friday.
They are tired because the class is long.
Hiroshi is at home because he is sick.
Not "Hiroshi is at home and he is sick." — say "Hiroshi is at home because he is sick.". because 放在原因前面（he is sick）。"and" 只是把两个想法加在一起，不能说明其中一个是另一个的原因。
试一试: Mateo is at home today ___ he is sick. (because / but / or) 答案: because — "He is sick" 是他在家的原因，所以用 because。"but" 表示意外，"or" 表示选择，两个都说明不了原因。
试一试: Yasmin: Do you play basketball here with your friends on Mondays? Diego: I like basketball, ___ I never play it here. (but / and / or) 答案: but — Diego likes basketball, but he never plays it here——两个想法是冲突的，所以用 but。"and" 只是把两个想法加在一起，并不能表现出冲突。
试一试: Sofia goes to bed early ___ she is tired. (because / but / or) 答案: because — 累了是她早睡的原因，所以用 because。"but" 表示意外，而这里并没有意外。

把两个意思连在一起时，你选的词说明它们是什么关系：两个意思能放在一起，用 and；两个意思有冲突，用 but；要在两个里面选一个，用 or。

Diego plays soccer and basketball.
Mei goes running but she does not go swimming.
Do you read or watch TV after dinner?
Not "I like tea but coffee." — say "I like tea and coffee.". 这里茶和咖啡都是“喜欢”，所以中间用 and。but 留给两个有冲突的意思。
试一试: Amina: You have time for only one. The class at six ___ the class at seven? Mateo: The one at seven, please. 补全 Amina 的问题。 (or / and / but) 答案: or — Mateo 只有时间上一节课，所以 Amina 把两节课摆在他面前让他选：or。and 等于两节都给他，可他只有一节课的时间。这两句话里没有冲突，所以也没有需要 but 表示的转折。

and、but、or 和 because 你已经一个一个用过了。这里四个放在一起：and 把两个意思并列，but 让它们形成对比，or 给出二选一，because 让后一个成为原因。

Lani reads and listens to music.
Lani reads but she does not watch TV.
Does Lani play games or watch TV?
Lani is tired because she runs every morning.
试一试: Farid: Are you at the pool this evening? Matilda: The pool is open, ___ I am very tired. 补全 Matilda 说的话。 (and / but / because) 答案: but — Farid 问 Matilda 去不去。泳池开着，是吸引她去的理由；她很累，又让她想待在家里，所以后一个意思是对前一个的转折：but。and 只是把两件事列出来，并没有回答问题。泳池开着也不是她累的原因，所以不是 because。

想问别人原因，就用 Why 开头提问。回答通常用 Because 开头。

Why is Yasmin at the gym every Tuesday? Because she goes swimming there.
Why does Sofia read at the library? Because she has a new book.
Why are you tired? Because my class finishes very late.
Not "Why are you happy? And my class is finished." — say "Why are you happy? Because my class is finished.". Why 问句问的是原因，回答通常用 Because 开头。
试一试: Wei: ___ do you go to Farrisen Gym? Lani: Because the pool is quiet. 补全 Wei 的问题。 (When / How / Why) 答案: Why — Lani 用 Because 开头，而以 Because 开头的句子是在说原因，所以 Wei 问的是原因：Why。How 问她怎么去，When 问哪天或几点，Lani 这两样都没回答。
