What Are Contractions in English?

Contractions are a way to make two words into one shorter word. We use an apostrophe (‘) to show where letters are missing.

English speakers use contractions all the time. They make conversations faster and more natural.

• You will hear them a lot when people speak.
• You will see them in informal writing, like emails to friends or text messages.

Common Contractions with 'to be' (am, is, are)

Many contractions use forms of the verb to be.

• I am 变成 I'm.
  例如 I'm happy to be here.
• You are 变成 You're.
  例如 You're a good student.
• He is 变成 He's.
  例如 He's my brother.
• She is 变成 She's.
  例如 She's going to the shop.
• It is 变成 It's.
  例如 It's a beautiful day.
• We are 变成 We're.
  例如 We're ready for the test.
• They are 变成 They're.
  例如 They're coming later.

Common Contractions with 'have' and 'has'

We also make contractions with have 和 has, especially in the present perfect tense.

• I have 变成 I've.
  例如 I've finished my homework.
• You have 变成 You've.
  例如 You've seen this movie before.
• We have 变成 We've.
  例如 We've been waiting for an hour.
• They have 变成 They've.
  例如 They've already eaten.
• He has 变成 He's.
  例如 He's got a new car.
• She has 变成 She's.
  例如 She's never visited London.
• It has 变成 It's.
  例如 It's been a long day.

Important: He's, She's, ， 和 It's can mean is 或 has. Look at the next word to know the meaning. If the next word is a past participle (like been, finished), it means has. If it's an adjective (like happy) or going, it means is.

Common Contractions with 'will'

We use contractions with will to talk about the future.

• I will 变成 I'll.
  例如 I'll call you later.
• You will 变成 You'll.
  例如 You'll be fine.
• He will 变成 He'll.
  例如 He'll arrive soon.
• She will 变成 She'll.
  例如 She'll help us.
• It will 变成 It'll.
  例如 It'll rain tomorrow.
• We will 变成 We'll.
  例如 We'll see you there.
• They will 变成 They'll.
  例如 They'll probably win.

Contractions with 'would' and 'had'

The contraction 'd can mean would 或 had. Again, look at the next word.

• I would 变成 I'd.
  例如 I'd like a coffee, please. (followed by a verb in base form)
• I had 变成 I'd.
  例如 I'd already eaten when they arrived. (followed by a past participle)
• You would 变成 You'd.
  例如 You'd better hurry.
• He had 变成 He'd.
  例如 He'd never seen snow before.

Negative Contractions (not)

We often contract verbs with not. The o 在 not changes to an apostrophe (') and joins the verb with n't.

• do not 变成 don't.
  例如 I don't understand.
• does not 变成 doesn't.
  例如 She doesn't like pizza.
• did not 变成 didn't.
  例如 We didn't go out last night.
• is not 变成 isn't.
  例如 It isn't raining now.
• are not 变成 aren't.
  例如 They aren't here yet.
• was not 变成 wasn't.
  例如 He wasn't at home.
• were not 变成 weren't.
  例如 You weren't listening.
• cannot 变成 can't.
  例如 I can't swim.
• will not 变成 won't.
  例如 She won't be late.
• could not 变成 couldn't.
  例如 I couldn't find my keys.
• should not 变成 shouldn't.
  例如 You shouldn't worry.
• would not 变成 wouldn't.
  例如 They wouldn't agree.

When NOT to Use Contractions

While contractions are common, there are times when it's better to use the full forms.

• Formal Writing: Avoid contractions in academic essays, official reports, or formal letters.
• Emphasis: If you want to emphasize a word, use the full form.
  例如 I AM going! (not I'm going!)
• Short Answers: Do not use contractions at the end of a short answer.
  正确： Yes, I am. (非 Yes, I'm.)
  正确： No, she isn't. (非 No, she's not.)

示例

• I'm tired, so I'll go to bed early tonight.
• They're not ready for the party yet.
• He's been waiting for you for an hour.
• It's a secret, so you mustn't tell anyone.
• We'd love to visit Spain again soon.
• She doesn't like coffee, but I do.

西班牙语母语者常犯的错误

Spanish speakers sometimes prefer to use the full forms of words, as contractions are not as common in Spanish grammar. However, in English, using contractions is natural and expected in most informal situations.

• Confusing similar-sounding words: Be careful with words that sound the same but have different meanings and spellings.
  • It's (it is/it has) vs. Its (possessive, like su in Spanish).
    错误： The dog wagged it's tail.
    右： The dog wagged its tail.
  • You're (you are) vs. Your (possessive, like tu/su in Spanish).
    错误： Your a great friend.
    右： You're a great friend.
  • They're (they are) vs. Their (possessive) vs. There (place).
    错误： Their going to the park.
    右： They're going to the park.
• Using contractions in formal writing: Remember to use full forms in academic essays or formal emails.
• Not using contractions in speech: While grammatically correct, always using full forms can make your English sound less natural to native speakers. Try to practice using contractions when you speak.
