lastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.GWD 21-30
In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.
Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?
A. A few children still use traditional wooden sleds.
B. Very few children wear any kind of protective gear, such as helmets, while sledding.
C. lastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
D. Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
E. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
The answer is C. But I think E is correct. lease help!
为什么选b?
题目说去年冬天受伤的儿童比十年前多
答案b说儿童不带保护装置
我的问题是:如果十年前儿童和去年的儿童都不带防护装置的话,仍然说明塑料的比皮革的危险啊?
这题我选b。理由是指出它因。即造成数字上升的他因。b中用的时态是现在时。
我想问一下到哪里找21套答案啊？找不到。5555555555555
谢谢！
啊,楼上的真仔细啊
谢谢
豁然开朗哟
我认为选C, lastic sleds can be used in a much wider variety of snow conditions than wooden sleds can. 因为在不同的雪的情况下都能玩，这样玩得次数时间就多了，儿童受伤的次数也会多，但不代表更危险了。
我不认为是B, 因为没有说过现在儿童的保护措施比以前的差，没有足够信息来比较。
肯定不是C，C正好证明Plastic sleds 能去更多的地方，所以更危险。但是为什么答案不是D呢？D说是因为撞到别的地方去了，所以出事，木制的也会撞到那些地方，所以不能说Plastic sleds更危险呀？B说的可能性孩子不带头盔，以前也可能不带呀？
支持C,9楼的说明Perfect。
跑10000公里的车出3次事故，跑10公里的车出2次事故，应该是10000公里的那辆更安全。这题的考点应该是绝对值和相对值概念的比较。

对不起，上面贴成B了，重贴一下。
