Many people travel to different places in the world by air．Usually it takes a long time，perhaps half a day，for passengers to stay in the plane．So airlines（航空公司）offer passengers food．But it is common that they feel bad about food taste．Do you agree？
To solve this problem，airlines try hard to improve their food．They would like to do so because they don't want to lose customers．
However，according to scientific research，part of the reason why plane food tastes bad is that at high altitude（海拔）we can not taste things as well as we do on the ground．Also scientists have found that our noses become very dry even before a plane takes off．As the plane moves up，the change in air pressure（气压）reduces one third of the sensibility（感觉）of our taste buds（味蕾）．So our taste buds become senseless．The sad face，however，is that our noses don't know it．
All of these help explain why food on the plane tastes so bad．They also help explain why airlines choose to offer passengers salty and spicy（辛辣的）food．Without doing so，the food would be tasteless．
Now there are many researches on this．According to one of them，some volunteers are asked to lie with their feet higher than their heads for weeks．And scientists write down their feelings about food taste．
Though scientists try their best，it is not as easy as they thought．Because they can't deal with the special environment successfully，such as the change in air pressure，making food taste good is still hard for them．

For years and years people have been saying that railways are dead. “We can do without railways,” people say—as if cars and planes have made railways unnecessary. We all keep hearing that trains are slow, lose money and are dying. But this is far from the truth. In these days of expensive oil, railways have become highly competitive with cars and planes. If you want to carry people or goods from place to place, they’re cheaper than planes. And they have much in common with planes. A plane goes in a straight line and so does a railway. What is more, a railway takes you from the heart of a city center. It doesn’t stop you as a car does on crowded roads. And no plane or car can ever carry as many goods as one train does.
Far from being dead, railways are much alive. Modern railway lines give you a comfortable journey. Where else can you eat well, sleep comfortably, feel safe and enjoy the scene while you are traveling at the same time? And we are only the beginning, for we have just entered the age of super-fast trains, which are traveling 150 miles an hour and more. Soon we will be wondering why we spent so much on highways and planes we can’t fly in because we don’t have enough money to buy the oil.Some people think railways are dying because______.

Would you like to have an electric car? We will see this kind of cars soon in America. These quiet, clean cars run on electricity. Carmakers will start selling electric cars in 2011.
The world’s population will jump from 6.8 billion to 9 billion by 2050. The need for cars will jump with it. But the oil(石油) won’t keep up with the number of cars on the road. So the price of oil will go up.
Electric cars aren’t perfect just yet. It can take eight hours to charge(充电) a car for only 100 miles of driving. And the distance(路程) that cars can go depends on driving conditions(条件). How far it travels depends on the weather and traffic.
Price is a problem, too. Electric models cost much more than oil-powered cars. The good news is that electric-car technology is getting better. As it does, the prices of this kind of cars are dropping.
To charge the car, the US Department of Energy is paying for at least 10,000 charging stations around the country. Private businesses are also getting ready for it. It will cost about $3 for each charge.
Carmakers are coming up with other ways to make the car cleaner and cheaper. Cars may run on clean diesel(柴油). So who knows what will power the car you may be driving in 10 years? The chances are that it will be something that’s clean and easy.The electric cars are ________.
A. large and noisy
B. large and quiet
C. clean and quietParagraph Two mainly tells us the reason why ________.

What’s the most important thing for you to have in your life? Somebody says hard-work, others suggest knowledge, love and luck.
If you arrange the 26 English letters alphabetically(按字母表的顺序) and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…, you can change an English word into a number. So hard-work becomes 8+1+18+4+23+15+18+11="98," meaning 98 is its mark; knowledge: 11+14+15+23+12+5+4+7+5="96," while love :12+15+22+5="54," and luck: 12+21+3+11="47," a small mark. None of these words can give one a full mark. What about money or prayer(祈祷)? They can’t , either.
Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude. Yes, attitude is the word. See for yourself: attitude: 1+20+20+9+20+21+4+5="100," a full mark.
Different attitudes lead to different ways of life. Most times people hope for a better life. It is possible that you will have a change for the better after you have changed your attitude.
When you change your manner and become friendly towards others, you’ll meet more smiling faces. In the same way, if you take a positive(积极地) attitude towards failure(失败), you’ll find you may have more chances to succeed.We can use ________ to represent “money”.
A. 72 B. 71 C. 70The underlined word “them” in the second paragraph refers to ________.
