     I had a summer camp with my classmates last year.

     Early in the morning, we gathered at the bus station. After saying goodbye to our parents, we got on the bus. ①It

took us more than two hours to arrive at the campground. 

     We got off the bus cheerfully, laughing and shouting; we jumped and ran all over the place. It was the first time for

us to be away from the parents. Some of us started to feel homesick(想家). However, when the night party and dances

began, the homesick was gone.

     The next day,②everybody rushed to the boating class, hoping to be at the head of the others. At first, my friends

and I worked hard but the boat wouldn't listen to us and kept going round and round. Then the teacher taught us how

to work together. After many tries, we did much better.

     Swimming class was my favorite. It was about the hottest time of a day and the best time to stay in the cool water.

The swimming teacher was a funny man, and during the class he often made us laugh happily.

     During the week I learned a lot of new things and made many new friends. I also learned how to take care of myself.

史密斯:根据《国际珍稀动物保护条例》的规定,杂种动物不属于该条例的保护对象。《国际珍稀动物保护条例》的保护对象中,包括赤狼。而最新的基因研究技术发现,一直被认为是纯种物种的赤狼实际上是山狗与灰狼的杂交后代。由于赤狼明显需要保护,所以条例应当修改,使其也保护杂种动物。
张大中:您的观点不能成立。因为,如果赤狼确实是山狗与灰狼的杂交种的话,那么,即使现有的赤狼灭绝了,仍然可以通过山狗与灰狼的杂交来重新获得它。
以下哪项最为确切地概括了张大中与史密斯争论的焦点()

A.赤狼是否为山狗与灰狼的杂交种

B.国际珍稀动物保护条例的保护对象中,是否应当包括赤狼

C.国际珍稀动物保护条例的保护对象中,是否应当包括杂种动物

D.山狗与灰狼是否都是纯种物种
