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 tea ___ coffee. She drinks 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。

but = 转折

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" 只用在意思一致的想法之间。
• 试一试: Hiroshi likes coffee ___ he doesn't like tea. (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。

or = 选择

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: Pick one drink: tea ___ coffee? (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。

because = 原因

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: Hiroshi is at home ___ he is sick. (because / but / and) 答案: because — "He is sick" 是他在家的原因，所以用 because。"and" 只是把想法加起来，"but" 表示意外，两个都说明不了原因。
• 试一试: I like coffee ___ I don't like tea. (but / and / or) 答案: but — 喜欢咖啡，不喜欢茶，两个想法是冲突的，所以用 but。"and" 只用在方向一致的想法之间。
• 试一试: Sofia sleeps 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。
