听力原文: Plants are adapted to the climate they live in for the most part. Trees in rainforests have broad leaves, shaped to encourage the heavy rain to run off the leaves. The large leaves encourage transpiration so the plants don't overheat. In very dry climates plants may develop an ability to store water, such as the cactus, which also has its leaves reduced into tiny spines which reduce transpiration to almost nothing so its precious water is conserved. At the first sign of drought, plants close their leaf pores to prevent wilting and slowing down growth so that they need less water. Coniferous plants also have small spiky leaves so that they don't lose too much water during the frozen winters. Grasses roll their leaves into tubes to protect their leaf pores from the drying effect of the wind. Tropical air plants have moisture sensitive plugs attached to their leaf pores which are pulled down over the pores, sealing them to hold in moisture, by the contraction of the stalks in dry weather.
Plants are affected by strong winds which make them grow thicker and more stunted stems to strengthen and prevent themselves from being blown over. A special sort of strong wood called "reaction wood" grows on the leeward side of tile wind. Plants are also susceptible to waterlogging and freezing and many plants have developed complex mechanisms and adaptations to protect themselves from disasters.
Trees in rainforests have broad leaves. The advantage is______.
A.to accept more sun light
B.to encourage the heavy rain to run off the leaves
C.to shade their roots
D.to hide their trunk
Now, taking books, or anything else, from a little girl is like taking candy from a baby, but the father of the little girl had his way and Robert got two of her books. "After all, that leaves you with nine", said the father, who thought he was a philosopher and a child psychologist, and couldn't shut his big stupid mouth on the subject.
A few weeks later, the father went to his library to look up "father" in the Oxford English Dictionary, to feast his eyes on(饱眼福) the praise of fatherhood through the centuries, but he couldn't find volume F~G and then he discovered that three others were missing, too—A~B, L~M, V~Z. He began to search his household, and learned what had happened to the four missing volumes.
"A man came to the door this morning", said his little daughter, "and he didn't know how to get from here to Torrington, or from Torrington to Winsted, and he was a nice man, much nicer than Robert, and so I gave him four of your books. After all, there are thirteen volumes in the Oxford English Dictionary, and that leaves you with nine".
How does the writer feel about taking picture books from a little girl?
A.This sort of thing is quite common.
B.It makes no difference to a child.
C.It is nothing to be surprised at.
D.It may hurt the girl's feelings.
