热闹农场大发现：动物们在做什么？
I go to a farm today. I see many animals. Two cows eat green grass. Three ducks swim in the water. Four brown hens have eggs. Five white sheep are near the tree. A big horse runs fast. A small dog plays with boys. The farm is good.
1.1. What do the cows eat?
A Green eggs.
B Green grass.
C Green apples.
D
解析：选B。B 细节理解题。原文明确提到“Two cows eat green grass”，即两头奶牛吃青草，因此B项 “Green grass” 正确。A项“绿鸡蛋”文中虽提到母鸡有蛋，但不是奶牛吃的东西；C项“绿苹果”文中没有依据。故选B。
2.2. Where do the ducks swim?
A Near the tree.
B On the grass.
C In the water.
D
解析：选C。C 细节理解题。原文明确提到“Three ducks swim in the water”，即三只鸭子在水中游泳，因此C项“In the water”正确。A项“在树附近”对应的是羊；B项“在草地上”不是鸭子游泳的地点。故选C。
3.3. How many sheep are near the tree?
A Five.
B Four.
C Three.
D
解析：选A。A 细节理解题。原文明确提到“Five white sheep are near the tree”，即树附近有五只白绵羊，因此A项 “Five” 正确。B项“Four”是母鸡的数量；C项“Three”是鸭子的数量。故选A。
4.4. What do the boys play with?
A A dog.
B A horse.
C A sheep.
D
解析：选A。A 细节理解题。原文明确提到“A small dog plays with boys”，即一只小狗和男孩们一起玩，因此A项 “A dog” 正确。B项“马”在文中是“runs fast”；C项“羊”在文中是“near the tree”，都不是和男孩一起玩的动物。故选A。
