Question

2.That is a chair.
3.What is that in English?
4.This is my friend.

Answer 1

注意man复数形式是 men， woman 是 women。
变复数后的句子应该是
1.Those are old men,
2.Those are chairs.
3.What are those in English?
4.These are my friends.
5.Those are not their bikes.
记住that 复数变those，this 变these，his /her / its 变their ，其他一般加S，特殊情况特殊对待，多注意下复数变换形式就好了。
