一、按要求写单词。
1. mango(复数) 2. let's(完全形式)
3. these(对应词) 4. they are(缩略形式)
5. up(对应词) 6. don't(完全形式)
7. sheep(复数) 8. are not(缩略形式)

1. mangoes；2. let us；3. those；4. they're；5. down；6. do not；7. sheep；8. aren't

1. mango是以有生命的o结尾的名词，复数形式加es，故为mangoes；2. let's是let us的缩略形式，完全形式为let us；3. these意为“这些”，对应词是those（意为“那些”）；4. they are的缩略形式为they're；5. up意为“向上”，对应词是down（意为“向下”）；6. don't是do not的缩略形式，完全形式为do not；7. sheep是单复数同形的名词，复数仍为sheep；8. are not的缩略形式为aren't。

二、选词填空。
1. My cousin can (make/makes) a paper plane.
2. Welcome (to/for) my home!
3. I can help (clean/cleaning) our school.

1. make 2. to 3. clean

1. 情态动词can后接动词原形，所以选make；2. “welcome to + 地点”是固定搭配，意为“欢迎来到某地”，所以选to；3. help后接动词原形，所以选clean。

三、完形填空。
Amy is in the 1 shop with her mother. They want 2 a fruit salad. They have some bananas and pineapples. But they don't have 3 mangoes. So they are going to（打算）buy some mangoes.
() 1. A. clothes B. toy C. fruit
() 2. A. make B. to make C. making
() 3. A. some B. a C. any

1.C 2.B 3.C

1. 根据后文提到的“fruit salad（水果沙拉）”可知，她们在水果店，故选C；2. 固定搭配“want to do sth”表示“想要做某事”，此处用动词不定式，故选B；3. 否定句中表示“一些”用any，some用于肯定句，a修饰单数名词，此处mangoes是复数且句子为否定句，故选C。

四、情境配对,从Ⅱ栏中选出Ⅰ栏的正确答句。
Ⅰ
Ⅱ
（）1. I like mangoes.
