“五一”假期，小明一家驾车外出旅游。一路上，所学的运动学知识帮助他解决了不少实际问题。（8分）

（1）经过某交通标志牌时，小明注意到了牌上的标志如图所示。小明想了想，马上就明白了这两个数据的含义：从交通标志牌到上桥距离为18 km，通过这段公路时，汽车的行驶速度不能超过40 km/h。若小明爸爸驾车通过这段路程用时30 min，则汽车的速度为____km/h，在遵守交通规则的前提下，试计算从标志牌到上桥最快要用____min。

（2）当汽车行至某高速公路人口处时，小明注意到这段高速公路全长180 km，行驶速度要求为：最低限速60km/h，最高限速120km/h。小明看了一下手表，此时正好是上午10∶00，他很快算出并告诉爸爸要跑完这段路程，必须在哪一段时间内到达高速公路出口处才不会违规。请你通过计算，说明小明告诉他爸爸的是哪一段时间？

进入考场的考生，直到听力考试结束前不得出入考场。

There are two factors which determine an individual’s intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

The importance of environment in determining an individual’s intelligence can be demonstrated by the case of the identical twins, Peter and Mark Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well to do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark’s IQ was 125, twenty five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

According to the passage, the average IQ is （）.

A．85

B．100

C．110

D．125
