Light travels at a speed which is about a million times faster than the speed of  sound. You can get some idea of this difference by watching the start of a race. If    you stand some distance away from the starter, you can see smoke from his gun      before the sound reaches your ears.
This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light   rays left the moon 1.3 seconds before they reached you. The nearest star is so far  away that the light that you can see from it tonight started to travel towards you    four years ago at a speed of nearly 2 million km. per minute. In some cases, the    light from one of tonight’s stars had started on its journey to you before you were born.
Thus, if we want to be honest, we can’t say, “The stars are shining tonight.” We   have to say instead, “The stars look pretty. They were shining four years ago, but    their light has only just reached the earth.”
小題1: Light speed is ______ sound speed
A．a(chǎn)s fast asB．a(chǎn) million times slower than
C．a(chǎn)bout millions of times faster thanD．a(chǎn)bout a million times faster than
小題2:If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that ______.
A．you can hear the sound before you see the smoke
B．the sound does not travel as fast as light
C．the sound will reach you before the man fires
D．sound travels about a million times faster than light
小題3:Sunlight obviously (明顯地) ______ than the light of the moon
A．has to travel a greater distanceB．moves less quickly
C．travels much more quicklyD．is less powerful(有力的)
小題4:The scientific way of saying "The stars are shining tonight" should be ______.
A．the stars have been shining all the time
B．the stars seen tonight will shine four years later
C．the stars were shining long ago but seen tonight
D．the starlight seen today could be seen four years ago

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach(菠菜) to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid(葉酸).
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.   
小題1:A good title for this reading passage is______.
A．Popeye the Sailor
B．The Truth About Spinach
C．A Mistake with Numbers
D．Folic Acid Makes You Strong
小題2:Why did many people eat spinach after they saw Popeye the Sailor?
A．They thought spinach made them strong.
B．They thought Popeye was funny.
C．Spinach had a lot of iron.
D．People liked folic acid.

A．made Popeye strong
B．was a green vegetable
C．had less iron than other green vegetables
D．had more iron than other green vegetables

Futurologists predict that life will probably be very different in 2050.
TV channels will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.
Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.
Robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots — they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere — in factories, schools, offices, hospitals, shops and homes.
Medical technology will have conquered many diseases. Today, there are devices（設(shè)備）that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.
Scientist will have discovered how to control genes（基因）. Scientists have already produced clones of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?

What would life be like without rich, creamy, mouthwatering, melt-in-your-mouth chocolate?
Life would be bitter for most Americans. They spend about $13 billion a year buying all sorts of chocolate treats.
However, for the African children who toil under slavelike conditions on cacao plantations, life is not sweet. The cacao bean is the main ingredient in the chocolate. According to a 2002 survey by the International Institute of Tropical Agriculture and the US Agency for International Development, about 284,000 children work in dangerous conditions on cacao farms in western Africa.
More than half those children are younger than 14. Many were sold into forced labor to work 12 hours or more a day on the cacao plantations.
A number of international organizations, including several African governments, recently began a program to eliminate(消除) child labor on cacao plantations. Under the program, government officials will remove children from abusive working situations while teaching farmers about child labor issues.
The program will also make borrowing money easier for cacao farmers. Officials hope farmers will use the money to invest in their farms and hire paid laborers.
小題1:The cacao bean is the main ingredient in _______.
A．treats
B．coffee
C．chocolate
D．cigarettes
小題2:How many children under 14 work on cacao farms in western Africa?

Are your children liked by their teachers? All parents want their children to impress(給...的印象) their teachers and succeed in school. You can get your children to impress their teachers by following these easy steps.
Make sure they’re prepared. Teachers are impressed by children coming to school prepared to learn. Make sure they have everything they need—pencils textbooks, erasers and so on.
Require them to be active in class. Teach them to ask teachers questions when they don’t understand something. Some children think teachers are bothered by questions, but most teachers are impressed when children take the initiative(采取主動(dòng)) in asking questions. They should take part in class discussions, giving their opinions politely.
Keep your children healthy. If your children are tired and hungry, they won’t be ready to learn. Children need at least 8 to 10 hours of sleep per night. Feed your children a solid breakfast and prepare a healthy lunch. Provide them with fruit and other healthy foods—apples or bananas are better for them than cookies.
Make sure that your children do their homework. If they really don’t understand it, discuss it with them patiently. Don’t help them do their homework. Teachers can always tell who it is that does the work.
Teach your children good manners and habits. Children need to arrive at the school punctually, and be polite to their teachers and classmates. Parents need to teach these skills at home.

Imagine, one day, getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours, and then, after a full day of work, going back home to Beijing and having dinner there.
Sounds unusual, doesn't it? But it's not that unrealistic, with the development of China’s high—speed railway system. And that’s not all. China has an even greater high-speed railway plan—to connect the country with Southeast Asia, and eventually Eastern Europe.
China is negotiating to extend its own high·-speed railway network to up to 17 countries in 10 to 15 years, eventually reaching London and Singapore.
China has proposed three such projects. The first would possibly connect Kunming with  Singapore via Vietnam and Malaysia. Another could start in Urumqi and go through Kazakhstan and Uzbekistan, and possibly to Germany. The third would start in the northeast and go north through Russia and then into Western Europe.
If China’s plan for the high-speed railway goes forward, people could zip over from London to Berlin in under two days.
The new system would still follow China’s high-speed railway standard. And the trains would be able to go 346 kilometers an hour, almost as fast as some airplanes.
China’s bullet train(高速客車(chē)),the one connecting Wuhan to Guangzhou, already has the   World’s fastest average speed. It covers 1,069 kilometers in about three hours.
Of course, there are some technical challenges to overcome. There are so many issues that need to be settled, such as safety, rail gauge(軌距),maintenance of railway tracks. So, it’s important to pay attention to every detail.
But the key issue is really money. China is already spending hundreds of billions of yuan on domestic railway expansion.
China prefers that the other countries pay in natural resources rather than with capital  investment. Resources from those countries could stream into China to sustain development.
It’ll be a win-win project. For other countries, the railway network will definitely create more opportunities for business, tourism and so on, not to mention the better communication among those countries.
For China, such a project would not only connect it with the rest of Asia and bring some much-needed resources, but would also help develop China’s far west. We foresee that in the coming decades, millions of people will migrate to the western regions, where the land is empty and resources unused. With high-speed trains, people will set up factories and business centers in the west once and for all. And they’11 trade with Central Asian and Eastern European countries.
小題1:China’s new high-speed railway plan will be a win-win project because     .
A．China will get much-needed resources and develop its western regions
B．China and the countries involved will benefit from the project in various ways
C．China will develop its railway system and communication with other countries
D．the foreign countries involved will develop their railway transportation, business and tourism
小題2:According to the passage, the greatest challenge to the new high-speed railway plan is     .
A．technical issues
B．safety of the system
C．financial problems
D．maintenance of railway tracks
小題3:Which of the following words best describes the author’s attitude towards China’s high-speed railway plan?
A．Critical.B．Reserved.C．DoubtfulD．Positive.
小題4:Which of the following might be the best title for the passage?
A．New Railway Standards
B．Big Railway Dreams
C．High-speed Bullet Trains

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

Just as some people think that certain numbers are lucky or unlucky, others believe that we can use numbers to understand our personalities, or predict what will happen to us in the future.
Numerology is a way of using numbers to describe a person’s character, and to make predictions about future life events. Numerologists use the numbers 1-9, 11 and 22 — also known as the “master” numbers — to help a person understand his or her personality, life goals, and destiny.
Numerologists consider your Life Path number to be the most significant because this number describes your character. To find this number, add together all the numbers in your date of birth. For example, a person born on April 25, 1985 would add the month (4), to the numbers of the date (2+5), plus the numbers of the birth year (1+9+8+5). In this case the total is 34, so this person’s life path number is 7(3+4). Numerologists believe that people with this number are peaceful and affectionate but can also be very reserved.
Your Expression number describes your talents and predicts how you should use these to fulfill your destiny in life. Numerologists assign a number between 1 and 9 to each of the letters in your name. These numbers are then added together in the same way as before to find your Expression number. Numerologists can also do calculations to predict when the most challenging periods of your life will be.
Numerologists also believe that the day a person is born is important. Each day of the month has a character description. People born on the fourth are said to be responsible, honest, and stubborn. People born on the fifteenth have very strong attachments to family and home. Those who celebrate their birthday on the thirtieth are artistic, creative, and imaginative, and often make good writers.
If we calculate the numerical value of our name and birth date, numerologists believe that we can learn more about our personalities. They also believe that we can predict our destinies, how our lives will progress, and what challenges we may face along the way. To the numerologist, numbers can be used in many more ways than we think.
小題1:If a person was born on November 8, 1995, what is his Life Path number?
A．7 B．8 C．9 D．11
小題2:To understand your abilities and how to use them in your life, you should calculate your ______.
A．Life Path number B．Expression number
C．birthdayD．name and birth date
小題3:According to the passage, a person born on the fifteenth tends to be _______.
A．stubborn B．home-lovingC．a(chǎn)rtistic D．imaginative
小題4:According to the passage, numerologists believe that _________.
A．Life Path number can be used to predict a person’s most challenging life periods
B．Expression number is the most meaningful for people to learn a person’s character
C．numbers can help people better understand themselves
D．numbers can be used to change a person’s future
小題5:The function of the passage is __________.
A．to raise doubts about the usefulness of numerology
B．to persuade readers about the benefits of the practices it describes
C．to describe some of the numerological practices and their purpose
D．to tease those who take such beliefs seriously
