问题 单项选择题

次生环境是指由于人类社会生产活动,导致原生自然环境的改变后形成的环境。其发展和演变仍受自然规律的制约。
根据定义判断,下列各项中不属于次生环境的是( )。

A.形成一个独立生态系统的人工鱼塘
B.建立的自然保护区
C.国际化大都市
D.花卉种植园

答案

参考答案:B

解析: 次生环境简单来说就是被人类生产活动改变后的非原生环境。它是原生环境演变成的一种人工生态环境。自然保护区以保护自然原生态为目的,与人类社会活动对自然的改造相悖,因此不可能是次生环境。而A、C、D都是人工改造后的环境,都属于次生环境。故本题答案选B。

完形填空

When most people travel, they spend some time booking hotel rooms. However, my friend Ashley and I were not like most people many years ago. We decided that backpacking through Ireland would be more fun if we “winged it”.

Winging it, of course, meant that we’d each buy a one-way ticket to Dublin, and give ourselves ten days to get back to Bath, England, where we were enrolled in a study-abroad program. The plan was to visit Dublin, Galway, Cong, and finally end things in Belfast, where we figured we could catch a flight back to England.

Unfortunately, Ireland had other plans for us, as nothing worked out the way in which we thought it would. After getting stuck in Galway and Cong for about seven days, we finally managed to take a bus trip from Cong to Belfast. The twelve-hour bus ride started at ten in the morning, which meant that we’d arrive in the heart of Belfast at around ten at night. Of course, like all transport, the bus ran late, and we ended up in Belfast at around eleven-thirty at night. As there were a ton of hotels around the area where it dropped us off, we weren’t too worried about finding a hotel room. But hotel after hotel turned us down.

After the third hotel turned us down and the fourth one was locked up for the night, Ashley and I started to realize that we had to spend a long night sleeping on a city bench. Like militant soldiers, we slept in turn as we were worried we would get robbed. The system worked, as we were able to stay safe while catching as much sleep as we could on the bench.

From this experience, I really learnt a good lesson.
