三、教学过程：
Step One: Lead-in and presentation.
1.Introduce the concept of the simple past tense.
We use the simple past tense to talk about things in the past.
Last Sunday morning, Millie and Amy went to Sunshine Park.
Yesterday morning, they went there again.
2.Recognize the structure of the simple past tense.
We form the simple past tense by adding ‘-ed’ to regular verbs.
Most verbs + ed walk—walked
Verbs ending in e + d live—lived
Verbs ending in a consonant + y -y + ied cry—cried
Short verbs ending in a vowel + a consonant double the consonant + ed stop—stopped
We form the simple past tense of irregular verbs differently. We do not add ‘-ed’.
No change cost—cost put—put
Change the vowel:write—wrote know—knew
Change the consonant make--- made
spend---spent
Change the vowel(s) and the consonant(s) leave---left catch ---caught
