Simple Past Tense


简单过去时式


The simple past tense is used for actions which took place at a given time in the past. We use words like yesterday, last night, last week, just now to show the past.

简单过去时式用于在过去的某个时间进行的动作。我们用 yesterdaylast nightlast weekjust now 等词来显示过去时式。

Actions that denote the past can be in the regular or irregular form.

简单过去时式的动词可分规则和不规则两种。

e.g.
Regular Verb
规则动词
Irregular Verb
不规则动词
  smile   smiled
  bake     baked
  laugh   laughed
  clean    cleaned
  speak   spoke
  drink   drank
  catch   caught
  swim    swam

There are some specific rules for the formation of regular verbs in the past tense form:

规则动词的简单过去时式可根据以下几种方式构成:

**  add ‘ed’ to regular verbs;
      在规则动词后加“ed”;
      e.g.    cook cooked
                 help helped

**  add ‘d’ to verbs that end with an ‘e’;
     在以“e”为结尾的动词加“d”;
      e.g.    tie tied
                 close closed

**  if the verb ends with a ‘y’ and a consonant 
      precedes the ‘y’, change the ‘y’ to ‘led’;
      在以一个辅音字母和“y”为结尾的动词后,
   把词尾“y”换成“ied”。

      e.g.    cry cried
                 try tried

Some verbs do not change their form.
有些动词的形式保持不变。
e.g.    cut cut
           hit hit
