技巧点拨：寻读(scanning)与限时训练策略
先看题目，找出定位词，然后再到文章里寻找相关信息，最
后进行对比；这个过程其实就是寻读。寻读能帮助我们在阅读时
最快速地获取最需要的信息。
在阅读训练过程中，应自始至终计时。读后将时间记下来，
和目标时间进行对比，在下一次阅读中调整阅读速度。另外由于
计时会带给人一种紧迫感，有助于保持精神的高度集中。
五、阅读理解。

A Bright Idea
Evans Wadongo was from a village of Africa.He had to do
homework by the light of a kerosene lamp (煤油灯).Evans’ eyes hurt
and this made studying difficult.It was common in his village.Many
children left school for this reason, so they remained poor for the rest
of their lives.
Although studying was difficult, Evans was an excellent student
and went to a university.He continued to worry about the kerosene
lamp.By this time, he realized it was not just bad for school children
but for the whole family.First, it can cause illnesses such as coughs.
Also, the light can hurt people’s eyes.Besides, it can lead to fires.
Lastly, kerosene is expensive, so families have less money for food.It
was difficult to come up with a different kind of lamp that was cheap
and good for the environment.Yet Evans did not give up.
One day, he had an idea.He could use a small solar light.Sunlight
is free and solar power is good for the environment.Evans built his
first solar lamp, and it worked.He began to build more lamps and sent
them to local families.An organization heard about this and provided
money for him to build more solar lamps.
Each lamp only cost $20.However, this was a lot of money to
many villagers, who only earned around $34 a week, so Evans made
sure he kept the cost down.First, Evans used recycled materials.Next,
volunteers built the lamps.Finally, people from many countries gave
away money to his team, so the lamps were usually free.
Thousands of people had safe light.Julia, a mother of three, said,
“Thanks to Evans, my children have light to read, and I have my own
light to cook.” The solar lamps made a big difference.
