下列动物中,属于我国特产的珍稀哺乳动物的是(  )

A.褐马鸡

B.扬子鳄

C.娃娃鱼

D.大熊猫

答案

A、褐马鸡是我国特产珍稀鸟类,被列为国家一级保护动物,仅见于我国山西吕梁山、河北西北部、陕西黄龙山和北京东灵山.1987年调查野生种群仅有数百只,根据2009年文献报道,我国现存的野生褐马鸡数量在17900左右.褐马鸡主要栖息在以华北落叶松、云杉次生林为主的林区和华北落叶松、云杉、杨树、桦树次生针阔混交森林中.属于鸟类.故该选项不符合题意;

B、扬子鳄或称作鼍,是中国特有的一种鳄鱼,是世界上体型最细小的鳄鱼品种之一.它既是古老的,又是现在生存数量非常稀少、世界上濒临灭绝的爬行动物.在扬子鳄身上,至今还可以找到早先恐龙类爬行动物的许多特征.所以,人们称扬子鳄为中生代的爬行动物“活化石”.我国已经把扬子鳄列为国家一类保护动物,严禁捕杀.故该选项不符合题意;

C、大鲵是世界上现存最大的也是最珍贵的两栖动物.它的叫声很像幼儿哭声,因此人们又叫它“娃娃鱼”,是国家二类保护水生野生动物,是农业产业化和特色农业重点开发品种;是野生动物基因保护品种.故该选项不符合题意;

D、大熊猫(学名:Ailuropoda melanoleuca),一般称作“熊猫”,是世界上最珍贵的哺乳动物动物之一,数量十分稀少,属于国家一级保护动物,被誉为“中国国宝”.大熊猫是中国特有种,属熊科,现存的主要栖息地在中国四川、陕西等周边山区.大熊猫憨态可掬的可爱模样深受全球大众的喜爱,在1961年世界自然基金会成立时就以大熊猫为其标志,大熊猫俨然成为物种保育最重要的象征,也是中国作为外交活动中表示友好的重要代表.故该选项符合题意.

故选:D.

Questions 1 to 5 are based on the following conversation.

M: You know, in designing this new town, we’ve tried to look backward at small-town America and take the best of those planning elements: houses close together; sidewalks, front porches, tree-lined streets, easy, non-automobile-dependent access to the town center and to your neighbors and to the school and the other institutions that are vital. And we’ve tried to take some of those ideas and update them and come up with a livable, workable place where people can go and rekindle the sense of community that seems to be missing from suburbs all across the country.

F: So give us a sense of how this new town was designed.

M: Houses are all very close together. We were just 10 feet apart from our neighbors on either side of us, and that’s pretty much the standard for the town. So, you have houses that are close together, houses that surround open areas. They have a lot of big parks, a lot of common areas. The theory is that you’re willing to sacrifice your private yard space--you don’t need a quarter of an acre or half an acre--if you have a public area where you can go and enjoy the facilities there and, most importantly, you can interact with your neighbors. That helps to create this sense of community that’s so important to many of these "new town" developments.

F: Now, I see this whole sense of community: It’s going to be a new town, but we’re going to do it with a sense of nostalgia for the past. Like, a lot of the houses had porches.

M: Yes, it would create a "front porch culture"--that people would be out on their porches talking to their neighbors next door and to people walking down the street or people riding their bikes, and there would be this culture that existed 40, 50, or 60 years ago. But that really has been one of the failures that we observed during our two years in this new town, and the people don’t spend very much time at all on their front porches. There are a couple of things going on. One is it’s central Florida, and it’s hotter than hell a good part of the year, and sitting on your front porch, even if you have a fan going, can be a very uncomfortable thing. People prefer to be inside in the air- conditioning.

F: What were some of the rules you had to live by in the new project And did any of those rules bother you

M: Well, the developer and I have different feelings about rules. His feeling is--now, if I can summarize his feelings for him--that you move in there knowing the rules, and if you don’t like them, you shouldn’t move in. I have some problems with rules. I just sometimes like to break them. And they just bother me because they’re in existence. But the rules sometimes were silly and sometimes weren’t. They dictated what color your curtains could be facing the street and actually asked a woman with red curtains to remove them.

F: Really Is that true

M: And they dictated where you could park your car and for how long. They dictated any sort of thing you could attach to your house. You couldn’t attach a satellite dish to your house. They dictated forever the color of your house. And they dictate how often you have to repaint your house. They’ve tried to go a step further and remove plastic flowers and plastic furniture from those all-important front porches. Some rules seem to go a little too far.
