The luxury of eating an apple on Mars could cost as much as US $22,000.That's because it costs about US $120,000 to launch a kilogram of anything into deep space.So getting enough food into orbit is a big problem facing astronauts on a trip to Mars.
After NASA (National Aeronautics and Space Administration) has no current plans to send astronauts to Mars, related research is being carried out-including the production of food.Astronauts on the international Space Station usually eat primarily freeze-dried food to which they add water.However, the weight of the packaging--almost as much as the food inside--costs a lot of money.The biggest problem of all is a psychological(心理上的)one.Scientists believe that astronauts will suffer without the variety offered by fresh vegetables.The answer is to grow at least some of the food.On a short trip it is imagined that astronauts will eat vegetables such as lettuce, spinach and carrots grown in a refrigerator-sized unit known as a "salad machine".On longer journeys they will actually grow vegetables in greenhouses on Mars. Martian astronauts will eat a vegetarian diet since it will not be practical to raise animals.To make up for the lack of meat, recipes have been created to add as much variety to the diet as possible, using only a basic number of products.It uses heat and mechanical force to transform soybeans into meat and cheese substitutes(替代物). The prized result of this research is a purely vegetable-based pizza with meat and cheese substitutes.
1.What is the best title for this story?
A.Space Food
B.Astronauts' Problem
C.The Packaging of Space Food
D.Mars Rover-Spirit
2.What is the main problem with the diet of astronauts on the international Space Station now?
A.The packaging is too expensive.
B.Only fresh vegetables are offered.
C.Too much water is needed for dried food.
D.There are not enough choices of food.
3.What is the "salad machine" in the spaceship for?
A.It stores vegetables.
B.It grows vegetables.
C.It cooks green salad.
D.It mixes green salad.
4.Which of the following will possibly NOT be included in the diet plan for Martian astronauts?
A.Vegetables.
B.A special kind of Pizza.
C.Meat.
D.Soybeans

Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you’re paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there’s going to be a need for orbital accommodation---or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel------private rooms, meals, bars. But they’ll also offer two unique experiences: impressive views----of Earth and space---and the endless entertainment of living in zero gravity---including sports and other activities that make use of this.
The hotels themselves will vary greatly----from being quite simple in the early days to huge luxury structure at a later date. It’s actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven’t expected launch costs to come down far enough to make them possible.
Lots of people who’ve been to space have described vividly what it’s like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don’t need to sleep much living in zero gravity, so you’ll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.
Of course all good things have come to an end. Unfortunately, And so after a few days you’ll find yourself heading back enough you’ll be much more expert at exercising in zero gravity than you were when you arrived. You’ll be thinking how soon you can save up enough to get back up again---or maybe you should change jobs to get to work in an orbiting hotel.
When traveling in space, most people would like to stay in orbit for a few days because _______.
A. It is expensive to travel in space
B. they would find the possible life in other star systems
C. they could enjoy the luxury of space hotels
D. they want to realise the full potential of tourism
Which of the following is a unique experience that space hotels will offer?

New archaeological discovers suggest that trade between Europe and Asia along the Silk Road probably began in some form many centuries earlier than once thought. The findings, coupled with a widening range of scientific and historical research, could add a fascinating new page to the epic of the Silk Road.
The latest and most surprising discovery is pieces of silk found in the hair of an Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.
The official origin of East-West commerce along the road is usually placed in the late 2nd century BC when an agent of the Chinese Emperor Wu-di returned from a dangerous secret mission(使命) across the western desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan and brought back knowledge of even more distant lands such as Persia, Syria and a place known as Lijien, perhaps Rome. Historians have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world’s two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthians of old Persia in exchange for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury markets of Rome.
But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.
59. The word “coupled” in the first paragraph could best be replaced by_______ .
A. produced B. continued
C. doubled D. combined
60. The silk thread found in the hair of an Egyptian mummy suggests that_______.
A. Egyptians had probably travelled to China to buy silk
B. trade along the Silk Road began earlier than once thought
C. historical research often achieves fascinating results
D. new light can now be thrown on ancient trading practices
61.Historians have always considered Zhang Qian’s mission important because they believe_______.
A. he brought back knowledge of Rome to the emperor
B. he discovered the Silk Road
C. he helped establish East-West trade
D. he travelled as far as Afghanistan
62. When did the official origin of East-West commerce along the Silk Road get to Persia?
A. About 1000 BC.
B. In the late 2nd century BC.
C. A million years ago.
D. In the 2nd century.
