A.单方法律行为

B.双方法律行为

C.有偿法律行为

答案

参考答案:A

解析:[考点] 法律行为的分类 本题涉及法律行为的分类问题。单方法律行为是仅由一方当事人的意思表示就能成立的民事法律行为;双方法律行为是由行为人双方相对应的意思表示达成一致而成立的民事法律行为;有偿法律行为与无偿法律行为相对应,是指具有对价的行为,有偿法律行为均为双方法律行为;实践法律行为与诺成性法律行为相对应,是指除了意思表示外,还需要以物的交付作为成立要件的民事法律行为。本题中,张三的授权行为仅须张三一方意思表示即可成立,故本题答案为A项。

     Too much TVwatching can harm children's ability to learn and even reduce their chances of getting

a college degree, new studies suggest in the latest effort to examine the effects of television on children.

     One of the studies looked at nearly 400 northern California thirdgraders. Those with TVs in their

bedrooms scored about eight points lower on math and language arts tests than children without

bedroom TVs.

     A second study, looking at nearly 1, 000 grownups in New Zealand, found lower education levels

among 26yearolds who had watched lots of TV during childhood. But the results don't prove that TV

is the cause and don't rule out that already poorly motivated youngsters (年轻人) may watch lots of TV.

     Their study measured the TV habits of 26yearolds between ages 5 and 15. Those with college

degrees had watched an average of less than two hours of TV per weeknight during childhood,

compared with an average of more than 2 hours for those who had no education beyond high school.

     In the California study, children with TVs in their rooms but no computer at home scored the lowest,

while those with no bedroom TV but who had home computers scored the highest.

     While this study does not prove that bedroom TV sets caused the lower scores, it adds to

accumulating findings that children shouldn't have TVs in their bedrooms.
