插图中有两个男孩，一个较胖，一个较瘦，医生在和他们交流。Unit 4主题是“Healthy food”，A选项强调喝牛奶、吃鸡蛋、多吃肉和鱼让身体强壮；B选项提到不要吃太多，鱼和蔬菜有益，还需要每天锻炼，更符合对不同体型孩子的健康建议，尤其是涉及饮食适量和运动，符合健康饮食单元内容。

2. Read, match and tick
1) Read and match
读一读本单元Reading time,完成相应任务。
I'd like some meat. It's healthy and good.
I eat from flowers. They're yummy and healthy.
Vegetables are healthy. I love carrots.
Nuts are healthy food.
2) Read, tick and say
What's healthy food?
健康饮食因人而异,请选择适合Zoom的建议(可多选),并补充说一说。
Eat some vegetables and fruit.
Candy and cake are yummy. Eat them every day!
Meat and fish are healthy, but don't eat too much.

1)（匹配题无选项，无需作答） 2) 选“Eat some vegetables and fruit.” “Meat and fish are healthy, but don't eat too much.”

本题可根据单元阅读内容完成匹配任务，再依据健康饮食的常识选择适合Zoom的健康饮食建议。对于匹配题，需熟悉单元阅读内容来进行连线；对于选择建议题，要知道蔬菜、水果是健康食物，糖果和蛋糕不宜每天多吃，肉类和鱼类虽健康但也不能过量食用这些健康饮食常识。
1) “I'd like some meat. It's healthy and good.”可与“meat”相关图（假设有图）匹配；“I eat from flowers. They're yummy and healthy.”可与“honey from flowers”相关图匹配；“Vegetables are healthy. I love carrots.”可与“carrots”图匹配；“Nuts are healthy food.”可与“nuts”图匹配。
2) 健康饮食应多吃蔬菜和水果，所以“Eat some vegetables and fruit.”是正确建议；糖果和蛋糕不宜每天吃，“Candy and cake are yummy. Eat them every day!”不是健康建议；肉类和鱼类虽健康但不能过量，“Meat and fish are healthy, but don't eat too much.”是正确建议。
