學英語這些年，你都犯了哪些語法錯誤？

 1.could, should, or would

這三個讀音相近的詞困擾了不少英語學習者。

“should”用來提供建議，比如“That shirt looks great on you. I think you should buy it.”。

“would”則是用來描述不可能或者虛擬的事情，比如“I would love to go to Italy, but I don't have enough money.”，這句話就是在說一件不可能發生的事。而“would”也可以表示委婉語氣，就像這句“Would you like some tea?”

“could”有三種用法——

①描述過去的能力，例：“When I was younger, I could run twice as fast.”

②描述將來可能發生的事，例：“If we work really hard, I think we could save up enough money for a vacation this year.”

③用于禮貌請求，例：“Could I have a cup of tea?”

2. there, their, or they're

這三個詞發音相同，用法卻完全不同。

“There”可以表示“那里”，表示一個指定地方，例如“The book is over there on the table.”；“there”也可以和be動詞一起使用構成“there+be"句型，例如“There are 5 cafes on this street.”。

“Their”是形容詞性物主代詞，意為“他（它）們的”，例如“That's their house.”。

“They're”是“they are”的縮寫，用法也是一樣，你可以說“They're going to play soccer with us tonight.”，也可以說“They are going to play soccer with us tonight.”，意思完全一樣。

3. its vs. it's

和上一條一樣，這兩個詞讀音相同，用法完全不同?！癷t's”是“it is”的縮寫，用法也是相同，你可以說“It's really cold outside today.”，也可以說“It is really cold outside today.”，意思完全相同?！癷ts”則是“it”的物主代詞形式，意為“它的”，例如“This city is known for its amazing pasta.”。

4. a vs. the

許多語言中并沒有使用定冠詞與不定冠詞，因此對有些英語學習者來說，這是種難以區分的概念。當你在談論一件事物的時候，一般使用不定冠詞“a”，例如“Let's watch a movie.”，這句話中的“movie”并沒有特指；如果你要談論的事物大家都很熟悉，那就可以使用定冠詞“the”，例如“Let's watch the movie.”，這句話中的“movie”則是表示一部談話雙方都知道的、正在談論的電影。
