问题 判断题

对人来说,血液中各种血细胞数量越多越好。           (       )

答案

题目分析:血浆主要功能是运载血细胞,运输营养物质和废物;红细胞主要运输氧气和一部分二氧化碳;白细胞的功能主要是吞噬病菌,防御感染;血小板的功能主要是释放有关的凝血物质和促进止血.红细胞增多运输氧气的能力强;血小板过多容易血栓;白细胞增多,表明人体内有炎症.当人体内出现炎症时,白细胞的数目就会增多,来吞噬一些危害人体健康的病菌.因此血液中各种血细胞的数量并不是越多越好.

Many teenagers feel that the most important people in their lives are their friends. They believe that their family members, and in particular, their parents, don’t know them as well as their friends do. In large families, it is quite often for brothers and sisters to fight with each other and then they can only go to their friends for advice.

It is very important for teenagers to have one good friend or a circle of friends Even when they are not with their friends, they usually spend a lot of time talking among them on the phone. This communication is very important in children’s growing up, because friends can discuss something difficult to say to their family members.
