Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.
The first is called the " tank(贮水池) test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode (爆炸)in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.
The most dangerous test happens when the new plane is going through test flights in the air. The pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.By doing the "tank test", the engineers can find out _______.
| A．the amount of air in the plane | B．the strength of the plane structure |
| C．the pressure inside and outside the plane | D．the power of the airplane engines |
What will happen to the plane under the "tank test"?
| A．It will be broken. | B．It will be made stronger. |
| C．It will be filled with water. | D．It will be tested by pilots, |
According to the text, why are test flights most dangerous?
| A．The plane may explode in the air. | B．The pilot may lose control of the plane. |
| C．The engines may be damaged. | D．Too much air may get into the plane. |
What might be the most suitable title for the text?
| A．Two Important Tests on Airplanes | B．The Importance of Flying Safely |
| C．The Danger of Testing Airplanes | D．How Airplanes Are Made and Tested |
Algae(水藻) are very simple plants. They grow in fresh water or salty water. Seaweed is algae that grow in salty water. Seaweed is red or brown in color. The Japanese people use these plants from the sea in many ways. From it, they make a food called Kombu. Kombu is seaweed that has been dried, cooked and pressed together. Then it is dried again and cut into long pieces. The Japanese eat a lot of Kombu and like it very much.
Japanese farmers often use seaweed as fertilizer. It makes their plants grow better. Many farmers also find seaweed makes a fine food for their animals.
From seaweed the Japanese also get iodine(碘), which they sell to other countries. Iodine is used in many ways all over the world. It is used in making medicine. It is added to the salt we use at the table. Scientists even use one form of iodine to “ seed clouds” when they want rain to 
fall. Kombu is a kind of ____ according to the text.
| A．plant | B．medicine | C．food | D．fertilizer |
In the last sentence of the text, “seed clouds” means ____.
| A．clouds spreading like seeds |
| B．the seeds like clouds |
| C．to make rain fall with human power |
| D．dropping seeds by clouds |
The main idea of the story is that ____.
| A．The Japanese eat seaweed when they want rain to fall. |
| B．Kombu is made into medicine for farmers. |
| C．The Japanese use seaweed in many ways. |
| D．The Japanese eat a lot of Kombu. |
The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth . Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July , a piece four kilometers wide enters the Earth’s atmosphere (大气层) with a massive explosion . About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero .Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same and?What is mainly described in the passage?
| A．A historic discovery. | B．An event of imagination |
| C．A research on space. | D．A scientific adventure. |
When the first piece hits the South Atlantic, it causes________ .
| A．an earthquake | B．damages to cities |
| C．an Earth explosion | D．huge waves |
Why can’t the northern half of the earth escape for long?
| A．Because the land is covered with water |
| B．Because the light and heat from the sun can not reach the earth. |
| C．Because people there can not live at the temperature of zero. |
| D．Because wars break out among countries. |
By giving the example of dinosaurs, the author tries to prove________ .
| A．animals could not live in the cold climate |
| B．what happened 65 million years ago was an invented story |
| C．the human beings will die out in 2094 |
| D．the Earth could be hit by other objects in space |
Who is there among us who hasn’t dreamed of having his or her own small (maybe , several years later , even big )business , and having wonderful freedom , both from a boss and from the time clock ; the freedom to make up our own rules for our work , and our own plans —arranging our own hours of work ? That way work would be both painless and fun. Or, so we imagine.
Well, in fact it isn’t quite as simple as that. Yes , it is true that being the boss has its satisfactions and that you can arrange your working hours freely if you own your own small business . But in those early years of starting your own business, you shouldn’t think of a free day, not to mention flying off for a month’s vacation. It is not unusual for new business owners to work seventy or eighty hours a week , and if there is a day off , that day might need to be devoted to accounting (算账).
But this negative picture doesn’t destroy the beautiful hopes. The possibility of getting something wonderful in return—both material and mental—continues to drive that large number of people who start up small businesses each year in the United States.From the first paragraph, we know that everybody hopes________ .
| A．to rule others | B．to be his or her own boss |
| C．to get a time clock | D．to be free from work |
Most new business owners have to________ .
| A．work more than 10 hours a day | B．devote himself to accounting |
| C．fly to some places in the world | D．have a day off in a week |
The expression “negative picture” most probably means “________ “.
| A．a terrible experience | B．a poor picture |
| C．limited freedom | D．unpleasant situations |
The beautiful hopes will never be destroyed because________ .
| A．people love beautiful things by nature |
| B．people have a strong desire to seek personal gains |
| C．small businesses make big money each year in the US |
| D．small businesses have advantages over big companies |

If a person forgets names, places or facts —and has trouble with everyday things like reading or shopping —it may not mean you are getting old. It could be Alzheimer’s disease. So it’s important to see a doctor as soon as you can.
There is no cure for Alzheimer’s. But a drug called ARICEPT has been used by millions of people to help their symptoms (症状).
In studies, ARICEPT has been proved to work for Alzheimer’s . It has helped people improve their memory over time. It has also helped them to keep doing everyday things on their own.
Ask your doctor if ARICEPT is right for you or your loved one. It is the Number One drug for Alzheimer’s in the world. The sooner you know it’s Alzheimer’s, the better ARICEPT can help .
ARICEPT is good for many but may not be good for everyone. Some people may experience not sleeping well, feeling very tired, or not wanting to eat. In studies, these side effects weren’t serious at all and went away over time. Some people taking ARICEPT may feel light-headed. In this case you should tell your doctors because your condition may get worse.If one suffers from Alzheimer’s,________ .
| A．he has trouble with his memory |
| B．he can’t do everyday things on his own |
