问题 综合

读图,完成下列问题。

(1)此图是          (填二分或二至中的一个节气)日的太阳光照示意图。此时太阳直射点所在的纬线是_________。

(2)图中正午12时所在经线的字母代号是__________。

(3)这一天,A点所在地的昼长时间是__________小时,日出时间是     点。

(4)A、B、C、D四点的昼长由短到长排列依次是:               

(5)ABC三地自转线速度由大到小的排列顺序是     

(6)此时,地球上极夜区的范围是             

答案

(1)冬至   23.5°S(或南回归线)   

(2)B   

(3)12 、6   

(4)DBAC  

(5)ACB     

(6)北寒带

本题考查光照图的综合运用。一般可从图中获得基本信息,比如晨昏线的分布特征、自转方向、时间信息等等。

(1)根据图示的晨昏线特征:与极圈相切,北极圈内出现极夜,南极圈内出现极昼,判断为冬至日;太阳直射的纬度位置为南回归线。

(2)图示太阳直射点所在经线即为正午12时的经线,即B点所在经线。

(3)A位于赤道上,故终年昼夜平分,即昼长12小时,日出6时;

(4)由于此时太阳直射点位于南半球,故全球昼长的分布规律:越往南昼越长,故昼长从短到长为自北向南排。

(5)地球自转线速度的规律:自赤道向两极递减;

(6)图示南极圈以内出现极夜。

Bells sound. Lighted messages appear. Men and women work at computers. They talk on the telephone. At times they shout and run around.

This noisy place is a stock exchange (证券交易所). Here expert salespeople called brokers buy and sell shares(股份) of companies. The shares are known as stocks. People who own stock in a company own part of that company.

People pay brokers to buy and sell stocks for them. If a company earns money, its stock increases in value. If the company does not earn money, the stock decreases in value. Brokers and investors(投资者)carefully watch for any changes on the Big Board. That is the name given to a list of stocks sold on the New York Stock Exchange.

Investors and brokers watch the Big Board to see if the stock market is a bull market or a bear market. In a bear market, prices go down. In a bull market, prices go up.

Investors in a bear market promise to sell a stock in the future at a set price. But the investor does not own the stock yet. He or she waits to buy it when the price drops.

The meaning of a bear market is thought to come from an old story about a man who sold the skin of a bear before he caught the bear. An English dictionary of the sixteen hundreds said, to sell a bear is to sell what one has not.

Word experts dispute the beginnings of the word bull in the stock market. But some say it came from the long connection of the two animals – bulls and bears – in sports that were popular years ago in England.

Investors always care about the possibility of a company failing. In the modern world, a company that does not earn enough profit (利润)is said to go belly up. A company that goes belly up dies like a fish. Fish turn over on their backs when they die. So they are stomach, or belly up.

Stock market investors do not want that to happen to a company. They want a company whose stock they own to earn more profit than expected. This would sharply increase the value of the stock. Investors are hoping for a windfall(横财).
