【题目】读 “我国陕西省南部地区等高线地形图”,完成下列问题。

(1)图中A处的地形类型是_____________。

(2)据图中信息,推断渭河、汉江两河流域之间分水岭的大体走向是_____________。

(3)近些年来,渭河含沙量有所减少。请分析当地可能采取了哪些治理措施。

(4)图中B、C两处有一处是汉江的支流,请在答题卡上上相应位置画出此支流,并用箭头标出流向。

(5)分析一月份汉中比西安气温偏高的主要原因。

【答案】(1)高原

(2) 东西走向

(3)植树种草、修梯田、打坝淤地等

(4)从B处向东南方向画一平滑曲线箭头到汉江干流

(5)汉中北部有山地,减弱冬季风,纬度也比西安低,地处亚热带区域

【解析】(1)读图可知,图中A处的海拔在1000米以上,等高线较稀疏,地势比较平坦,所以该处的地形是高原。

(2)根据图中渭河和汉江之间的等高线的延伸方向大致是东西走向可知,该山脉是东西走向,该山脉是我国东西走向的山脉秦岭。

(3)渭河是黄河的最大支流,近年来,由于我国加大了对黄土高原的治理,植树种草、修梯田、打坝淤地等措施使水土流失减少,所以渭河含沙量有所减少。

(4)读等高线图可知,B处是山谷,C处是山脊,河流大多发源于山谷,所以从B处向东南方向画出平滑曲线箭头到汉江干流即可。

(5)读图分析可知,汉中北部有山地的阻挡会减弱冬季风,纬度也比西安低,地处亚热带区域,所以一月份汉中比西安气温偏高。

【题目】

As we know it is important for our health to have a good eating habit.

But what do you think can affect it? The custom of your country., the different kinds of food, or just your personal interest? The last study in theJournal of American College Health told us that in fact, the environment where we live also plays a role in eating.

Some students, male or female, live in dormitories (宿舍), and otherslive off campus (校园). So according to the different environment they have,researchers at Washington State University got some data(数据) and compared with daily food choices. They found there were big differences in the consumption(消耗) of fruit and vegetables, fish, unsweetened cereal, white bread, cookies and beer.

Basically, many students like to eat the food that is most available where they live. And they are strongly influenced by eating habits of their peers (同龄人). Men have more beer, meat and white bread than women. Women consume more diet soda.

The reason is very simple. Because we are social animals and generally likely to make a meal of whatever everybody else is having. So some experts advise that if you're trying to lose weight but your friends think pizza and beer is a balanced meal, then the problem is coming. And what you need to do is to change your eating habits or pack your bags.
