下面是以为同学针对问题“What is an activity that you enjoy doing with your friends and why? Please include specific examples and details in your explanation.”的回答。
There are two reasons why I think so. One reason is that playing sports help us create strong bonds of friendship. It creates many opportunities of cooperation if we have to beat others when play in a group.I don’t like exercising alone. It is really boring if you have to repeat some moves.I am really interested in playing sports with my friends.
第一句是总起句，应该用表起始的连接词，如: in the beginning, in the first place,等等;第二句是第一句的解释，因此可以用that is to say, in other words等等来联系这些关系。表递进的关系，可以用moreover。下面我们来看看修改后的答案。
As far as I am concerned, I really love playing sports with my friends. There are two reasons why I think so. Actually, one reason is that playing sports helps us create strong bonds of friendship. You know, it creates many opportunities of cooperation if we have to beat others when play in a group. Also, I don’t like exercising alone. Because it is really boring if you have to repeat some moves. For these two reasons, I am really interested in playing sports with my friends.
这样看起来，用上连接词以后，整个答案读起来都通顺了许多。
