Growing mushrooms(蘑菇) is probably the easiest thing you can do even if you are new to mushroom growing. It is becoming more common because restaurants are starting to create more dishes that include mushrooms.
Mushroom growing is easy. To start, you need to have a space where you are going to grow these mushrooms. It does not have to be a huge space but just enough for you to grow as many mushrooms as you need. When you have found the space perfect for you, you can start researching what kind of mushrooms you want to grow. There are a lot of mushrooms to choose from and not all of them are suitable to eat.
When you decide what kind of mushrooms you want to grow, you can start getting ready to plant the mushrooms. Sometimes you may want to hire some workers to help if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to have a business by yourself can be stressful. If you don’t have enough time to spend taking care of everything yourself, dome helpers may be the best choice.
After you have started the mushroom growing, you should regularly check that your mushrooms grow properly and that they are not being attacked by any pesticides(农药) or any other animals or something that could be dangerous to them. That is the worst part of mushroom developing. Protect your mushroom farm well with a fence(围栏) or a gate so that only you and your workers can get in and out.
Mushroom growing is not difficult and it is easy to get stared in the world of farming. You will soon possibly be able to provide some of the great cooks of the world with high quality mushrooms that will be enjoyed by thousands of people all over the world.

Do you want to be successful in everything you do? If so, then      _？ Here is an example.
There was a farmer who      _ corn (玉米) all his life. Each year he took his corn to the market. Then each time his corn was chosen as the _     and won the first prize.
One year a newspaper reporter interviewed him and learned something surprising about how he grew it.The farmer _     seed (做种子的) corn to his neighbors.
“How can you share your best seed corn with your neighbors？” the reporter asked.“You know they are taking part in the _     with you each year.”
“Why, sir,” said the farmer, “didn't you know？The wind picks up pollen (花粉) from the corn and moves it quickly from field to field. If my neighbors grow      __ corn, cross­pollination (异花传粉) will affect the quality of my corn. So if I want to grow good corn, I must _    _ my neighbors to grow good corn.”

LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is to send a few comets (彗星) in the direction of Earth, and its orbit (轨道) will be changed. Our world will then be sent moving into a safer older part of the solar system.
This idea for improving our climate comes from a group of US NASA (美国航空航天局) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—hopefully doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid (小行星) so that it passes close by our planet and sends some of its gravitational energy (重力势能) to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter (木星) or Saturn(土星). The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to worldwide warming, although the team was actually worried about a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere (生物圈)—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying sides, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation (误算) in orbit could fire it straight at Earth—with deadly results.
There is also the question of the moon. As the present issue of Scientific American magazine points out, if Earth was pushed out of its present location, it is “most likely the moon would be stripped (剥离) away from Earth,” it states. This would greatly change our planet’s climate.
小题1:What makes the scientists plan to move Earth?
A．A few comets are moving to the direction of Earth.
B．Earth’s working life is coming to an end soon.
C．Earth will become too hot for mankind to keep alive.
D．The moon is moving farther and farther away from Earth.
小题2:If the plan is successful, Earth will have a working life of ________ years.
A．12 billionB．6 billionC．18 billionD．24 billion
小题3:What serious problems might the plan cause according to the passage?
A．The comet might hit Earth and man might lose the moon.
B．Earth might be moved too far away and man might die because of the coldness.
C．The comet might hit Jupiter or Saturn and never return to Earth.
D．Earth’s working life might be greatly shortened.
小题4:What does the underlined word “compromise” mean?
A．provideB．benefit (受益)C．shareD．endanger

When the traffic lights turn red, we will stop driving a car or crossing a street. Why is red used for traffic lights instead of other colors?
As we know, scattering (散射) happens when light goes through the air. For the same media(媒质), if the wavelength islong, the scattering will be short. If the wavelength is short, then the scattering will be long.
Of all lights we can see red has the longest wavelength, so the scattering is the weakest. That means the red light travels far. In fact, it travels farther on rainy days.
Using the red light can help drivers in farther areas sec the lights. It helps drivers stow down or stop in lime. If drivers don't see the red light until they are close, they may not be able to stop the car in time. An accident may happen Red can also excite people. We can act more quickly when we see the color red. In a word, red lights help drivers stop in time and help prevent accidents.
小题1:When the traffic lights turn ______, we will stop driving a car.
A. red    B green     C. yellow
小题2:According to the passage, the scattering of the red light is the _______.
A. longest    b. weakest       C. farthest
小题3:The underlined word "wavelength" means________ in Chinese.
A.波浪        B.光波      C.波长
小题4:What can the red light help drivers do?
A. It can help drivers in farther areas see the lights.
b. It can help drivers slow down or stop in time.
C. A and b
小题5:Which of the following is the best title?
A. Why do accidents happen
b. How does the red light travel
C. Why do we use red traffic lights

The planets aren’t the only wanderers(漫游者) of the sky. There’re some things even farther and longer. Long after people were no longer afraid of planets, they still thought the comets(彗星) were bad objects that traveled in the sky. They were afraid that the comets would suddenly land on the earth and hurt them.
But, in fact, even if a comet did hit the earth, nothing much happened. A comet is really a harmless （无害的）thing.
Comets have round heads and long tails , and they are very bright. Sometimes they look like heads with long hair flying with them. That’s why they’re called comets. Comet means long-haired.
Like the stars and planets, comets are far away. But we can know its size. The head of a small comet is as wide as the Pacific Ocean. And a big comet’s head is ten times as big as the earth. Its tail is millions of kilometers long. Then why wouldn’t the great big thing hurt us if it hit the earth? Because it isn’t solid. It’s thin like cloud. Its tail is nothing but bright gas. And its head is made of small pieces and they could not hurt the earth.
Some comets can be seen for a few months. Then they go away. Some of them come back in a certain number of years. Some are never seen again.
Perhaps these comets that never return have broken into pieces. For some astronomers  think that shooting stars(流星) are pieces of broken comets.
小题1:People were afraid ________.
A．comets are different from planets
B．comets travel in the sky
C．comets are much bigger than the earth
D．comets could hit the earth
小题2:Comets have long tail like ________, so we call them comets.

小题3:From the passage we know the tails of comets are made of  ________.
A．waterB．solidC．gasD．small stones
小题4:The underlined word “astronomers” may mean ________ in Chinese.
A．心理学家B．艺术家C．天文学家D．考古专家
小题5:Which of the following is TRUE ?
A．A comet is a kind of planets.
B．Comets are all ten times as big as the earth.
