After an extra day in space,the crew of Discovery returned to Earth,landing at Edwards Air Force Base in California early on Tuesday morning.The shuttle and its crew spent two weeks in space,most of it aboard the International Space Station.It was the first flight of NASA's space?shuttle fleet since February 2003,when the shuttle Columbia came apart while re?entering Earth's atmosphere.?

NASA officials delayed Discovery's return for one day because of cloudy weather in Florida,where the shuttle was supposed to lanD. On Tuesday morning,mission controllers ?directed? Discovery to a landing site in California,where the skies were clear.The crew members will have to wait until Wednesday to see their families when they all meet together in Houston at the Johnson Space Center.?

Discovery had a very busy mission in space,compared to past missions.The space shuttle docked with the International Space Station most of the journey,delivering badly needed ?supplies? and repairing damaged parts.The crew spent a lot of time testing new repair techniques on their own shuttle,conducting three different spacewalks(where astronauts exit the space shuttle to do work outside).On the third spacewalk,astronaut Steve Robinson went underneath the shuttle to remove material sticking out from between the spacecraft's ?protective? tiles.?

There were concerns in the last remaining days of Discovery's mission that a torn heat blanket—another shield against overheating in the space shuttle—may pose a problem to crew members. NASA officials and technicians worked on ways that the crew could fix the problem, but later decided it was not a risk.?

With the shuttle and its crew safely back on firm ground, NASA is hailing this mission, labeled STS?114,as a huge success. “I hope this shows people that we're coming back,” NASA spaceflight chief Bill Readdy said after Discovery's successful landing. “We've got some more work to do. We know what we need to do and we'll do it.?

Which of the following isn't included in the jobs of the shuttle Discovery?

A. Delivering supplies to the International Space Station.?

B. Conducting different spacewalks.?

C. Testing new repair techniques.?

D. Finding the cause why the shuttle Columbia came apart.?

But for the cloudy weather, the shuttle Discovery would have landed_______.

A. in Florida a day earlier B. in Florida a day later?

C. in California a day earlier D. in California a day later?

Which is the most probable period of time that Discovery was aboard the International Space Station?

A. Six days. B. Two weeks.?

C. Nine days. D. Two weeks and an extra day.?

Mr. Glen is a millionaire. Five years ago, after returning from abroad to his motherland, he 36 up his small company. Speaking of success, Glen often tells us a story about his ___ 37 expensive “school” fee. He always owes his success to it.

At that time, Glen, who already got a Ph. D. degree, decided to return to the homeland, starting a company. Before 38 , he bought a Rolex watch with the 39 made through years of work after school and the scholarships. At the airport he had to accept the routine customs check. The watch on his wrist was also demanded to be 40 down for inspection. Glen knew that carrying the 41 goods out had to pay the tax. And he worried about paying 42 for his watch. So when he was checked, he told a lie that his watch was a worthless 43 . When he was 44 of his “smarts”, immediately, 45 the presence of Glen, the officers hit the watch, which 46 nearly 100,000, into pieces on hearing Glen’s words. Glen was amazed, 47 he understood why, he was taken to the office to be 48 strictly. For many times of entry-exit 49 he knew that only those people in the “blacklist” would “enjoy” this special treatment. The officers looked out every thing carefully in the box, and warned him no matter

50 time of entry and exit he must accept the check and if 51 reusing and carrying fake and shoddy(劣质的) goods, he would be charged according to law! Suddenly, his face turned red, and he had nothing in mind after 52 the plane for long.

After returning to the homeland, he often told the story to his family, and his employees, too. He said that this made a deep 53 on him, because the additional high “school” fee that he had ever paid made him realize the value of 54 , which he would 55 as the secret of his success forever.

There was great excitement on the planet of Venus (金星) . Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago.

Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology.

"We have come to the conclusion, based on last week's satellite landing," Prof. Zog said, "that there is no life on Earth."

"How do you know this?" the science reporter of the Venus Evening Star asked.

"For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive."

"What does this mean as far as our flying saucer program is concerned?"

"We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned."

"Are there any other dangers that you discovered in your studies?"

"Take a look at this photo. You see this dark black cloud hovering (盘旋) over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there."

"Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer."

"If all you say is true, won't this set back the flying saucer program several years?"

"Yes, but we shall continue as soon as the Grubstart gives us the added funds(资金)." Profession. Zog replied.

A. the feasibility of landing a satellite on Earth

B. the possibility of making a first-rate flying saucer

C. the feasibility of sending a Venus Being to Earth

B. the Earth's atmosphere is filled with deadly gases

C. there is a low level of oxygen for Venusians

D. there is no air on the planet of Earth

A. landing a manned flying saucer on Earth will be carried out soon

B. Venusians will land on Earth to help to stop serious pollution

C. it’s unnecessary to land a manned flying saucer on Earth at present

The bar-tailed godwit （斑尾鷸）has just broken its own record for the world’s longest non-stop flight, including humans in planes, according to a report made by Lund University Press. The bird can fly non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82 hours without a stop.

The bar-tailed godwit’s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as short as what the bar-tailed godwit travels.

One reason for the bar-tailed godwit’s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from Lund University, says, “This figure is extremely low compared with other birds.” The bird also has a special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels fast, compared to other birds and animals.

Many questions remain about this bird record holder that never gets lost in the air. Researchers wonder whether it has an inside compass (指南针) that helps it to know the direction. Please watch how beautiful bar-tailed godwits look as they come in for a landing, along with other birds.

1.For the flight from Alaska to New Zealand, the bar-tailed godwit__________

A．doesn’t need to stop to eat

B．is afraid of hot weather

2.The main reason why the bar-tailed godwit can break the record is that it ______.

A．eats little food every hour

B．has a special body shape

C．stores much water in its body

D．has very light body weight

3.The last paragraph tells us that _________.

A．researchers have understood the bird very well

B．the bird has a very good sense of direction

C．there are still many who doubt the bird’s ability

D．the bird has an inner compass
