The reason that these that these two wonders of nature are so difficult for many adults to explain to children is that they are not very well understood by adults themselves. For example, did you know that the lighting we see flashing(闪烁) down to the earth from a cloud is actually flashing up to a cloud from the earth？ Our eyes cheat us into thinking we see a downward motion when it’s actually the other way round. But then, if we believe only what we think we see, we’d still insist that the sun rises in the morning and sets at night.
Most lightning flashes take place inside a cloud, and only a relative few can be seen jumping between two clouds or between the earth and a cloud. But, with about 2,000 thunderstorms taking place above the earth every minute of the day and night, there’s enough activity to produce about 100 lightning strikes on the earth every second.
Parents can use thunder and lightning to help their children learn more about the world around them. When children understand that the light of the lightning flashes reaches their eyes almost at the same moment, but the sound of the thunder takes about 5 seconds to travel just one mile, they can begin to time the interval between the flash and the crash to learn how close they are to the actual spark.

Section A
Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.
Questions 26 to 35 are based on the passage you have just heard.
Physical activity does the body good, and there's growing evidence that it helps the brain too. Researchers in the Netherlands report that children who get more exercise, whether at school or on their own,26to have higher GPAs and better scores on standardized tests. In a27of 14 studies that looked at physical activity and academic28, investigators found that the more children moved, the better their grades were in school,29in the basic subjects of math, English and reading.
The data will certainly fuel the ongoing debate over whether physical education classes should be cut as schools struggle to30on smaller budgets. The arguments against physical education have included concerns that gym time may be taking away from study time. With standardized test scores in the U.S.31in recent years, some administrators believe students need to spend more time in the classroom instead of on the playground. But as these findings show, exercise and academics may not be32exclusive. Physical activity can improve blood33to the brain, fueling memory, attention and creativity, which are34to learning. And exercise releases hormones that can improve35and relieve stress, which can also help learning. So while it may seem as if kids are just exercising their bodies when they're running around, they may actually be exercising their brains as well.
