Questions are based on the following passage.
New Stanford research reveals that farmers in Europe will see crop yields affected as global temperatures rise, but that adaptation can help slow the decline for some crops.
For corn, the anticipated loss is roughly 10 percent, the research shows.
Farmers of these crops have already seen yield growth slow down since 1980 as temperatures have risen, though other policy and economic factors have also played a role.
"The results clearly showed that modest amounts of climate change can have a big impact on yields of several crops in Europe," said Stanford doctoral student Frances Moore, who conducted the research with David Lobell, an associate professor of environmental Earth system science.
Moore described the results as somewhat surprising because Europe is fairly cool. "So you might think it would benefit from moderate amounts of warming,"she said. "Our next step was to actually measure the potential of European farmers to adapt to these impacts."
"By adaptation, we mean a range of options based on existing technologies,such as switching varieties of a crop, installing irrigation or growing a different crop, one better suited to wanner temperatures," said Lobell. "These things have been talked about for a long time, but the novelty (新奇) of this study was using past data to quantify (量化) the actual potential of adaptation to reduce climate change impacts. We find that in some cases adaptation could substantially reduce impacts, but in other cases the potential may be very limited with current technologies."
Moore pointed out that the biggest issues are often how quickly farmers in Europe will adapt to climate change (adaptation uncertainty) and how crop yields will respond to climate change (response uncertainty).
"This paper has shown that crops in Europe are sensitive to wanning and that adaptation can be important in reducing that impact," Moore said. "The next question is how quickly farmers will use the available options for adapting.
Europe has already seen a lot of warming, so we should expect to already see adaptation if farmers are quick to respond to climate signals,"

听力原文:M: Hello.
W: Hello, welcome to "Advice" radio program. What's your name?
M: Jim.
W: What's your problem?
M: Er...well I'm er...beginning to lose my hair. Er, I went to the doctor, but he just said there was nothing I could do about it. He said it was probably hereditary. My father was bald by the time he was thirty.
W: And how old are you?
M: Me? I'm twenty-eight.
W: And are you losing a lot of hair then?
M: Well, it comes out a lot when I comb my hair and you can see a thin part on the top of my head,
W: Does that really worry you, Jim?
M: Well, I don't like it. It's old, you know, looks old. I don't want to look like a middle-aged man at twenty-eight. And I wonder if there is some special shampoo I should use, and if you could tell me one that I should buy, something like that, you know, to stop it getting worse.
W: Well, you know, Jim, to be honest with you there's not really a lot you can do about it, actually, I'm afraid. I mean, baldness is one of those things that, in my experience, you just have to try to accept. Some men find it more difficult to accept baldness than others. There is one piece of advice, though, Jim, and that's don't try to comb your hair over the bald or thin patch. Whatever you do, don't comb it over because that usually looks ridiculous. And the other thing that usually looks ridiculous is a man with a wig, that is, the false hairpiece. Don't let anyone persuade you to buy one of those false hairpiece things, because they usually look much worse than a bald man. I actually think bald men can look very attractive. My husband is bald and I think it really suits him.

Of course, the truth is not so simple. This century, the work of cognitive(认知的) psychologists had illuminated the subtle forms o? daily learning on which intellectual progress depends. Children were observed as they slowly grasped concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one. Psychologists have demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed (哄) into finding the total. Such studies have suggested that the basics of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers is itself far from innate.
What does the passage mainly discuss?
A.Trends in teaching mathematics to children.
B.The use of mathematics in child psychology.
C.The development of mathematical ability in children.
D.The fundamental concepts of mathematics that children must learn.
