问题:

(5分)随着赠台大熊猫“团团”和“圆圆”入住台北市立动物园,标志着两岸同胞即将进入“团圆”的新时代,随行的17棵珙桐树苗也在台北安家;同时大陆也接受了台湾同胞回赠的长鬃山羊和台湾梅花鹿。请回答:

(2)1969年,最后一只野生台湾梅花鹿被捕杀,该物种已濒临灭绝。一般来讲,一个物种的灭绝,代表着这个物种所有基因的总和,即          也随之消失;同时,该种生物的灭绝必将影响其他生物的生存和它所在的生态系统,即也会加速           多样性和             多样性的丧失。

(3)被称为植物界“大熊猫”和“活化石”的珙桐与处于同等地位的桫椤相比,二者在分类特点上的主要区别是

Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station(加油站)about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register(收款台), I said hello to an older couple who were also paying for gas.

I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.

I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I'd left the lights on all day, and the battery(电池)was dead. Then I noticed that the Friendly Ford dealership - a shop selling cars - was right next door. I walked over and found two salesmen in the showroom.

"Just how friendly is Friendly Ford?" I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.

"Thank you" - two powerful words. They're easy to say and mean so much.
