蝙蝠能够飞行,但不属于鸟类,而是哺乳动物。主要理由是

A.蝙蝠有四肢

B.蝙蝠的心脏有四腔

C.蝙蝠有着恒定的体温

D.蝙蝠有胎生哺乳的生殖发育特点

答案

答案:D

题目分析:蝠能够飞行,但不属于鸟类,而是属于哺乳类.主要理由是:因为它不具有鸟类的一般特征.鸟类的翼是前肢变成的,而它的翼是由前后肢和尾部之间的皮膜连成的.而且蝙蝠的体表无羽而有毛,口内有牙齿,体内有膈将体腔分成胸腔和腹腔,这些都是哺乳动物的基本特征,更重要的是,蝙蝠的生活方式是胎生哺乳,而不像鸟类那样卵生,这一特征证明蝙蝠是名副其实的哺乳动物.

故选:D

写作题

阅读下面的短文,然后按要求写一篇150词左右的英语短文。

There are all kinds of stress in our daily lives such as stress from work, stress from study and stress from examinations. How to manage stress is thus a very important problem that we have to deal with properly. I think stress itself doesn’t exist. It’s only because we consider things to be bad and regard all of them as our own fault and won’t forgive ourselves. As we all know, there is nothing you can do without error. So it’s impossible to expect everything to be perfect. If we have done our best,  although not successfully, there is nothing to regret. And we don’t need to blame ourselves continuously. In fact we have done a quite good job. Then we will feel the stress less. We will stay healthy and do well in the future. Eventually we will be successful.
