Four hundred years ago, an Italian scientist named Galileo Galilei became the first person to see the craters(环形山) on the moon. Galileo was one of the first people to use a telescope to study the sky. Since then, telescopes have become the most important tool used by astronomers. Scientists never stop finding new ways to make these instruments more powerful. In the next several years, two new telescopes with different purposes are to be used.
One of the telescopes, called Pan-STARRS, could save humans from dying out. Nick Kaiser, a scientist who works on the project, says the Pan-STARRS telescope has been designed to find “90 percent of all killer asteroids(小行星) near Earth”.
Pan-STARRS, like most telescopes, uses mirrors and lenses(透镜) to provide pictures of outer space. Giant mirrors are used to “gather” light. They reflect the light onto the lens of a camera, which can then record the image.
When completed, Pan-STARRS will include four telescopes which will be put on top of a mountain on the Hawaiian island of Maui. Only one telescope is in place and working now. Each telescope will take pictures of one patch of sky for about 30 seconds, and then move on to another patch. Every night, each telescope will take pictures of about 1,000 patches. Every week, each telescope will have photographed the whole sky.
Each of the four telescopes will take pictures of the same patches of sky. One telescope, working alone, may sometimes incorrectly show an asteroid. If there are three other telescopes working, astronomers can use them to see if there really is an asteroid coming our way. By using four telescopes instead of one, scientists hope to get a better picture of space. If a giant asteroid was identified, astronomers would try to break it up long before it reached Earth.
1. Galileo Galilei is mentioned to ____________.
A.tell us the history of telescopes |
B.introduce the topic of the passage |
C.show people his contributions |
D.tell us about the craters on the moon |
2. For what purpose is Pan-STARRS designed?
A.To find more asteroids around Earth. |
B.To help scientists know Earth better. |
C.To find killer asteroids coming towards Earth. |
D.To learn about asteroids in outer space. |
3.What is paragraph 3 mainly about?
A.The use of mirrors in a telescope. |
B.Why Pan-STARRS is different. |
C.How telescope “gather” light |
D.How a telescope works. |
4.How many patches is the whole sky divided into when Pan-STARRS is working?
A.1,000 | B.7,000 | C.21,000 | D.28,000 |
5. The four telescopes will take pictures of the same patches of sky because _____.
A.one telescope often takes unclear pictures |
B.one telescope may provide incorrect information |
C.information from just one telescope is usually incorrect |
D.no information is allowed to be identified based on single information |

One morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.
Though he was tired, Howe slept badly. He turned and turned. Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practised sewing machine.
Elias Howes was not the only one in finding the answer to his problem in this way.
Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.
To know the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious(无意识的), but still active part understands your experiences and goes to work on the problems you have had during the day. It stores all sorts of information that you may have forgotten or never have really noticed. It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake. However, the unconscious part acts in a special way. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called “secret messages to ourselves”.
1.The problem Howe was trying to solve was________.
A. what kind of thread to use
B. how to design a needle which would not break
C. where to put the needle
D. how to prevent the thread from getting caught around the needle
2.Thomas Edison is spoken of because _____ .
A. he also tried to invent a sewing machine
B. he got some of his ideas from dreams
C. he was one of Howe's best friends
D. he also had difficulty in falling asleep
3.Dreams are sometimes called“secret messages to ourselves” because ________ .
A. strange images are used to communicate ideas
B. images which have no meaning are used
C. we can never understand the real meaning
D. only specially trained people can understand them

IT'S a mystery that has puzzled scientists. Five years ago, researchers found an area in the Atlantic Ocean seabed, where a part of the Earth's outer layer, or crust(地壳), is missing. A thick layer of dark green rock, which is usually found deep inside the planet, lies exposed.
The crust, mantle(地幔) and core(地核) are the main layers that make up the planet. The mantle rests between the crust and the core.
Last month, a team of 12 British scientists set off on a six-week trip to study the hole in the crust.
The hole is about 4,800 meters below sea level and is believed to be more than 48,000 meters long and more than 48,000 meters wide. Scientists think that there are other nearby gaps. "It is like a window into the interior (内部) of the Earth," says scientist Bramley Murton, who is part of the research team.
The site where the hole is located is part of a ridge (山脉) of undersea volcanoes. There, two of the plates that make up the Earth's surface meet. The plates are always moving. When the plates move away from each other, lava rushes up from the mantle to fill the gap and form a new crust. But this did not happen in the area where the hole is located.
The hole is giving researchers a good opportunity to study what's below the Earth's surface. The team will use a special robotic tool to film the area and get samples of the exposed mantle. They hope to study everything from the chemistry of the oceans to how the Earth's surface behaves under the sea.
1. What's the title for the passage?
A. How to study the earth.
B. The formation of the earth.
C. A hole in the earth.
D. Studying the inside of the earth.
2.For the main layers of the earth, which one is right?
A. crust, mantle, core B. seabed, crust, mantle
C. seabed, mantle, core D. crust, seabed, core
3.How does the hole come into being?
A. It's because of a volcano eruption.
B. It's because of the plates movements
C. It's because lava rushes up from the mantle
D. It's not clear from the passage.
4.By studying the hole, the scientists want to do the following except____.
A. knowing what's below the Earth's surface
B. getting samples of the exposed mantle
C. getting the film of the hole
D. studying the chemistry of the oceans

About five years ago, an American electrical engineer named Scott Brusaw and his wife Julie came up with the idea of putting solar panels on the ground rather than the roof. Then they began to develop the Solar Roadway specially for a new type of cars-eco-cars. The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun while providing safer driving conditions, along with power and data delivery. They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same amount of money that is being used to build and resurface current roads can be used to build the Solar Roadsays.
Each Solar Road Panel measures roughly 4 meters and contains a microprocessor(微处理器)that monitors and controls the panel, while communicating with neighboring panels and the vehicles traveling overhead. The inventors suggest that this provides a communication device every 4 meters on every road which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems. The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions(抓地力)they need.
According to the inventors, the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop, or at any business that has paved Solar Road Panels in their parking lots.
The inventors say their Solar Roadway has many functions and advantages from main roads to drivewasys, parking lots, bike paths, sidewalks and runways. The Federal Highway Administration has given Brusaw $100,000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring.
1.In the inventors’ opinion, the Solar Roadway______.
A. is too expensive to build at present
B. costs no more money than current roads
C. can provide as many data as present computers
D. will bring them a large sum of money
2.The underlined word“they”in Paragraph 2 refers to______.
A. the panels B. the inventors C. the researchers D. the vehicles
3.The Solar Roadway includes all the following advantages EXCEPT_______.
A. providing safer driving conditions
B. helping drivers communicate with each other while driving
C. creating and carrying clean renewable electricity
D. warning drivers of various speed control problems
4.What can be the best title for the text?
A. Solar-powered smart road of the future
B. The great changes on the roadway
C. The influence the Solar Roadway has on people
D. The Solar Road-a much faster road

Three years ago when I was still in the university, I also worked at a restaurant.
An old man named Mr. Candido Filio was one of our regular customers at the restaurant. He was one of the most intelligent people I’ve ever known.
Every Sunday the Philippine Star Newspaper had a special page for word puzzles and among his peers (同龄人), Mr. Filio held the record for solving all the puzzles in less than five minutes. He encouraged me to solve them too and for months and months, I did my best to beat him but failed.
Then one Sunday, I did it! I was able to complete them before anyone else. Everyone cheered for me. He came up to me with a smile and said, “No one has ever beaten me before. You’re the first. I’ll have a prize for you tomorrow.”
The next day, he gave me a special Scrabble (拼字游戏) set. I would have never been able to afford one like that by myself. Then he said to me, “Kate, what do you think is man’s final goal in life? Happiness, isn’t it? You are happy and that should be considered as a success. Many people spend a lifetime searching for that. Be thankful that you have found it.” I looked at him and knew that my life had changed, probably forever. He must have known that I always felt sad about not having much money.
He encouraged me to learn the game and love words. And true to his words, I was never able to beat him again.

More than four decades ago British scientist Robert Edwards first witnessed the miracle of human life growing inside a test tube at his Cambridge lab. Since that ground-breaking moment, more than four million babies have been born through IVF and in 2010 his great contribution to science was finally recognized as he was awarded the Nobel Prize for medicine.
The prize for Dr. Edwards, who was given a Daily Mirror Pride of Britain Award in 2008, includes a £900,000 check. The Nobel Assembly described IVF as a “milestone in modern medicine”.
With the help of fellow scientist Patrick Steptoe, the Manchester-born physiologist developed IVF - leading to the birth of the world’s first test tube baby. Dr. Steptoe died 10 years later but their work has transformed fertility treatment and given hope to millions of couples.
It was a scientific breakthrough that transformed the lives of millions of couples. They said: “His achievements have made it possible to treat infertility, a disease which makes human unable to have a baby. This disease has been afflicting a large percentage of mankind including more than 10% of all couples worldwide.”
Louise Brown, the world’s first test tube baby, made international headlines when she was born in Oldham, Manchester, in 1978 to parents Lesley and John who had been fruitlessly trying for a baby since 1969.
IVF-----in-vitro fertilization is the process whereby egg cells are fertilized outside the body before being implanted in the womb. After a cycle of IVF, the probability of a couple with infertility problems having a baby is one in five—the same as healthy couples who conceive naturally.
Professor Edwards, who has five daughters and 11 grandchildren, began his research at Cambridge University in 1963, after receiving his PhD in 1955. He once said: “The most important thing in life is having a child. Nothing is more special than a child.” With the help of fellow scientist Patrick Steptoe, Prof. Edwards founded the Bourn Hall clinic in Cambridge shire, which now treats more than 900 women a year. Each year, more than 30,000 women in Britain now undergo IVF and 11,000 babies are born as a result of the treatment.
But his work attracted widespread criticism from some scientists and the Catholic Church who said it was “unethical and immoral”.
Martin Johnson, professor of reproductive sciences at the University of Cambridge, said the award was “long overdue”. He said: “We couldn’t understand why the Nobel has come so late but he is delighted - this is the cherry on the cake for him.”
Professor Edwards was too ill to give interviews but a statement released by his family said he was “thrilled and delighted”.
1.What is Robert Edwards’ contribution to science?
A. Enabling millions of couples to live a better life.
B. Seeing the wonder of the first tube baby growing
C. Helping couples with infertility to have tube babies.
D. Challenging a disease which stops human having a baby.
2.What does the underlined word “afflicting”(Paragraph 4)most probably refer to?
A. Troubling B. Developing
C. Improving D. Confusing
3.Why did Professor Edwards begin his research on tube baby?
A. Because he thought it of great significance to have a child in life.
B. Because the birthrate around the world was unexpectedly low then.
C. Because a special child did make a difference to an ordinary family.
D. Because his fellow scientist wanted to give hope to the unlucky couples.
4.It can be inferred from Paragraph 8 and Paragraph 9 that ___________.
A. Professor Edwards deserved the prize for his breakthrough.
B. different opinions were voiced on Professor Edwards’ achievement.
C. some people envied Professor Edwards for his being awarded.
D. the prize was late because the finding was first considered immoral.
5.What might be the best title for the passage?
A. Life Stories of Robert Edwards
B. Preparations for Having a Baby
C. Nobel Prize for IVF Expert Edwards
D. Treatment of Infertility in a Lab
