下图表示我国江南某林场,其树木砍伐后在地面留下的一截树桩,天空中有一群大雁向左作长途飞行。据此回答题。

据图分析此时的季节是

A.夏季

B.秋季

C.春季

D.冬季

答案

答案:C

题目分析:由图中树桩上年轮的分布可知,图中左侧密集,因为是在北半球,所以该侧为北;同理右侧为南方。图中大雁向北飞,我国正值北半球春季。

点评:本题以图片为载体考查光热条件对年轮间距的影响。在我国由于处于北半球,由于树木南北两侧光热条件不同,生长速度也不同,向阳一侧的光热条件较好,生长速度相对于背阳一侧较快,年轮间距也相对较大。

     The very wealthy English Baron Fitzgerald had only one child, a son, who understandably was the

apple of his eye. His wife died when the child was in his early teens. So Fitzgerald devoted himself to

fathering the kid. Unfortunately the son died in his late teens.

     Meanwhile, Fitzgerald's wealth greatly increased. He spent a lot on art works of the masters. Later

Fitzgerald himself became seriously ill. Before his death, he had carefully prepared his will as to how his

wealth would be settled-to sell his entire collection at an auction(拍卖).

     Because of the large quantity and high quality of his collection, a huge crowd of possible buyers

gathered for the auction. Many of them were museum directors and private collectors eager to bid(出

价). Before the auction, the art works were shown, among which was a painting of Fitzgerald's son by

an unknown artist. Because of its poor quality, it received little attention.

     When it was time for the auction, the auctioneer gaveled(敲槌)the crowd to attention. First the

lawyer read from Fitzgerald's will that the first art work to be auctioned was the painting of his son.

     The poor-quality painting didn't receive any bidders. . . except one-the old servant who had served

the son and loved him, and who for emotional reasons offered the only bid.

     As soon as the servant bought the painting for less than one English pound, the auctioneer stopped

the bidding and asked the lawyer to read again from the will. The crowd became quiet, and the lawyer

read from the will: "Whoever buys the painting of my son gets all my collection. "Then the auction was

over.
