题目内容

【题目】读读某区域经纬网图和地球公转,完成下列各题。

⑴A点的经纬度是______________,该点一年中有____次太阳直射现象。

⑵B点在A点的_______方向。

⑶B点位于五带中的___________。

⑷当太阳直射A点时,地球位于公转轨道示意图上的______处。

⑸地球由公转轨道的①处向②处运动过程中,北京市的白昼将变_____(填“长”或“短”)。

【答案】(1) 90°E 23.5°N

(2)东南

(3)热带

(4) ②

(5)长

【解析】试题分析:本题综合考查地球仪知识和地球的公转。

⑴A点的经度为90°,向东增加,故为东经90°;所在的纬线为北回归线,故纬度为23.5°N,由于北回归线是太阳直射的最北的界线,故一年中有一次阳光直射的现象。

沿着经纬线把A点的基本方向标记出来,根据B点在A点的方位即可判断,B点位于A点的东南方向。

据图中可知,B点位于赤道上,位于南北回归线之间,故可以判断其位置为热带。

太阳直射A点即直射到北回归线上,是每年的夏至日,由上可知,此时地球运动到的位置为处。

⑸①处为全球昼夜平分,处北半球昼最长、夜最短,故白昼将变长。

【题目】

Almost every Chinese person can recite the two lines of the famous poem, “Every grain on the plate comes from hard work(谁知盘中餐,粒粒皆辛苦).” But sadly, many of us don’t actually get the real meaning of these lines: Don’t waste food.

A CCTV program, News One Plus One, reported that the food Chinese people throw away every year is enough to feed 200 million people for a year.

Do we have too much food? Of course not. According to the UN World Food Program, there were 925 million hungry people around the world in 2010, especially in developing countries. Six million children die of hunger every year.

Chinese people are well known for being hospitable(好客的) and generous. Many even feel that they lose face if their guests have eaten all the food on the table.

Luckily, a number of people have realized the importance of saving food. Last November, Li Hong, a waitress in a restaurant in Nanjing, got fired because she took someleftoverfood home for her son. Many people stood by her side and criticized(批评) the waste of food.

What should we do in our daily lives to waste less food? Here are some tips:

1. Do not order too much in a restaurant. Only order as much as you want to eat. If you cannot eat all the food you ordered, take the rest of it home.

2. Don’t be too picky(挑剔的) about food. Some food may not taste great, but your body needs it.

3. Keep an eye on what food you have at home. Don’t buy too much, especially for vegetables and fruit.
