科学家对火星地表勘测表明火星可能存在河流,证据是有类似于地球流水地貌的存在。下面两图为火星某处,左图为火星某处数字高程模拟图,右图是利用该高程分析提取的可能出现的河流的水系图。完成下列各题。

小题1:以下哪些河流河段的流向与该地相似

A.亚马孙河下游

B.尼罗河上游

C.刚果河下游

D.密西西比河上游小题2:判断高度表中乙丙数值大小关系及甲地的地貌类型

A.乙 > 丙;河漫滩

B.丙 > 乙;冲积扇

C.乙 > 丙;U型谷

D.丙 > 乙;三角洲

答案

小题1:A  

小题2:D

题目分析:

小题1:读图可以判断,该河流向大致是自西向东流。亚马孙河下游流向自西向东,A对。尼罗河上游大致自南向北流,B错。刚果河下游大致是自东向西流,C错。密西西比河上游大致是自北向南流,D错。

小题2:找出河流的位置,河道海拔高度比两侧河岸低。读图,根据弯曲判断河道所在位置的颜色深,所以高度数值是丙 > 乙,A、C错。冲积扇出现在河流出山口,甲处河网密集,位于河网中,不可能是山口的冲积扇,只可能是河口的三角洲,B错、D对。

Diets aren’t the way to go when it comes to losing weight. That’s because they create temporary eating patterns—and, therefore, temporary results. So what’s the best way to drop excess weight? Create a new normal! Weight loss is most likely to be successful when people change their habits, replacing old, unhealthy ones with new, healthy behaviors. Here are five ways to make that happen.

Take exercise.  小题1:  . Walking the family dog, cycling to school, and doing other things that increase your daily level of activity can all help you look and feel good and keep weight off.

  小题2:  One reason people get less exercise these days is that they spend too much time watching TV, looking at the computer, or playing video games. Limit recreational screen time to less than 2 hours per day.

Watch out for unhealthy drinks. Another key factor in weight gain is that more people drink sugary drinks, such as sodas, juice drinks, and sports drinks.  小题3:   

Eat some fruits and vegetables every day. Fruits and vegetables are about more than just vitamins and minerals.  小题4:   And when you fill up on friuts and vegetables, you’re less likely to overeat when it comes to high-calorie foods like chips or cookies.

 小题5:  People who don’t have breakfast often feel so hungry that they eat more later on. So they are likely to get more calories.

A.Regular physical activity burns calories and builds muscles.

B.So go for water or low-fat milk instead of soda.

C.They’ve also packed with fiber, which means they fill you up.

D.Don’t skip breakfast.E. Share your breakfast with others.

F. It is bad for your eyes to spend too much time watching TV.

G. Reduce screen time.
