Q: Read the following article and answer the question. Article: You can't see any object unless light from that object gets into your eyes.Some of the things you see give off light of their own. The sun,the stars,a lighted lamp are the examples that can be seen by their own light.But most of the things you see are not giving off light of their own.They are just reflecting light that falls on them from the sun or some other luminous bodies.The moon,for example,doesn't give off any light of its own.It is not 1uminous.You see it because sunlight falls on it and some of the sunlight reflects on the earth.So moonlight is only second--hand sunlight. When you look at a book,it sends some of the light which fails on it to your eyes,and you see the book.If light could be kept out from where you're so that there would be no light from the book to reflect.Then you couldn't see the book even with your eyes wide open.Light travels so fast that the time in which it travels from the book you're reading to your eyes is as short as if there were no time at time.Light reaches us from the moon,which is about 380,000 kilometres away,in only a little more than a second. Question: Light travels about _ kilometers per second. Answer:

OPTIONS:
- 300,000
- 100,000
- 400,000
- 190,000

A: 300,000

Q: Read the following article and answer the question. Article: "What's the name of our neighbor? I can't remember right now. " Have you ever heard your grandparents ask questions like this sometimes? Usually, we think that older people's memory becomes bad because their brains get weak. But now a team of scientists at the University of Tubingen in Germany has a new idea.[ "The human brain works slower in old age," says Michael Ramscar, the lead scientist. "But only because they have stored more information overtime. " The findings are based on a series of computer simulations of learning and memory. Scientists let the computers read a certain amount of words and learn new things each day. When the computer "reads" only so much, its performance on cognitive tests is similar of a young adult. But if the computer learns the experiences we might encounter over a lifetime, its performance is similar to that of an older adult. Often it is slower, but not because its processing capacity has declined. Rather, increased "experience" has caused the computer's database to grow, giving it more data to process-which takes time. This is similar to old people. Imagine a person knows two people's birthdays. Another person knows the birthdays of 2000 people, but can only match the right person to the right birthday nine times out of 10. Can you say the first person has a better memory than the second person? Question: According to the research, why do old people forget people's names easily? Answer:

OPTIONS:
- Because they have a very poor memory.
- Because they are too old to remember things.
- Because their brains become weaker than before.
- Because they have stored too much information.

A: Because they have stored too much information.

Q: Read the following article and answer the question. Article: My parents divorced when I was 8 years old. Their marriage was a mistake of World War II. And about 50 years ago, I was the only child I knew who didn't have a father at home on Father's Day. Divorce was very uncommon back then. So when my friends were in town shopping for presents for their fathers, I decided since my mother was both Mother and Father, no one else was like her, who better deserved(be worth) a present on Father's Day than her? I bought her a little set of tools, just a few things, hammer, pliers and screwdriver and a box to put all these things in. I got some ideas from my grandfather and named it Mother's Tool Box. She was excited, more at the thought of being cared for on Father's Day than of the present. She always said she liked her Father's Day memories better than the Mother's Day ones. It made her feel special -- and she was. I have noticed in the past few years, greeting cards are even made for "Mother on Father's Day". Ever since then, my mother has got cards on Father's Day. By the way, she knew just how to use those tools and others she had ever used over the years. Question: "Hammer, pliers and screwdriver" are probably things _ . Answer:

OPTIONS:
- more often used by men
- that cost a lot of money
- very popular at that time
- that his mother liked most

A:
more often used by men
