Six seconds after its launch in Virginia, US, an unmanned rocket bound for the International Space Station （ISS） exploded, disappointing people both on Earth and in space．
Hundreds of millions of dollars worth of cargo was destroyed in the Oct． 28 explosion due to An“equipment failure”, said Orbital Sciences, the company hired by NASA for the resupply mission．
The rocket was carrying a cargo ship loaded with 2,200 kilograms of supplies such as food, tools, parts, and experiments． Roughly a third of the cargo was a series of scientific investigations． Some of them were from high school students in the US． For example, 10 students from the Cristo Rey Jesuit College Preparatory School of Houston were conducting experiments about microgravity and put their samples on the rocket． “I know that failure is a part of science, but I really feel sorry for my students," science teacher Greg Adragna told the Houston, Chronicle ．
Astronauts at the ISS felt a more urgent disappointment, however． The cargo included 617kg of food． Now they will have to rely on supplies from a Russian launch on Oct． 29．
Launched in 1998 and involving the US, Russia, Canada, Japan, and the member countries of the European Space Agency, the ISS is one of the most ambitious international collaborations in history． Currently, there are six astronauts at the station, five male and one female． Three are from Russia, two are from the US, and one is from Germany． They have lived together for about six months． The station gets regular resupplies from Earth, using unmanned spacecrafts． Food is always a big part of the supplies． Most of the food is frozen and ready to eat, and often tastes bad-somewhat like trying to eat when you have a heavy cold．
To make space life better, however, scientists have made breakthroughs． Earlier this year, Russian astronauts managed to grow a variety of crops aboard the station． Next year they are going to try to grow rice and other plants． And, as transporting water to space is expensive, astronauts are looking for ways to recycle water． "Astronauts on board the ISS already drink water distilled from sweat and urine<尿） ," Russian news agency RIA Novosti reported．
Is that the reason the astronauts were so disappointed not to get the water from the failed resupply mission, by any chance? What is the author-s main purpose in writing the article?
| A．To explain what caused the explosion of NASA-s unmanned rocket． |
| B．To inform us of the explosion of NASA-s unmanned rocket and its effects． |
| C．To tell us about astronauts lives at the International Space Station． |
| D．To tell us how the world reacted to the explosion of NASA-s unmanned rocket． |
The underlined word “cargo” in the second paragraph is closet in meaning to
| A．goods | B．equipment |
| C．food supply | D．investigation |
How did teacher Greg Adragna feel about the explosion of the rocket?
| A．Angry． | B．Anxious． |
| C．Frustrated． | D．Unconcerned． |
We can conclude from the article that the situation seemed for astronauts on board the ISS when the rocket exploded．
| A．hopeless | B．interesting |
| C．depressing | D．dangerous |
Which of the following statements is TRUE about the ISS, according to the article?
| A．Half of the astronauts at the ISS are from the US． |
| B．The ISS was set up by four countries． |
| C．The water that astronauts at the ISS drink is mainly made by recycling． |
| D．Most of the food astronauts eat at the ISS is frozen and tastes bad． |
People who breathe infected air from a TB patient can become infected with the tuberculosis（肺结核） bacteria（细菌）. However, most people with active tuberculosis do not expel （驱逐，逐出）very many TB bacteria. So, the spread of the disease usually does not happen unless a person spends a large amount of time with a TB patient. Those most at risk are family members, friends and people who live or work closely with a patient.
Tuberculosis can attack any part of the body. However, the lungs are the most common targets（目标） of the bacteria. People with the disease show several signs. They may expel air from the lungs suddenly with an explosive（爆炸性的） noise. This kind of cough continues for a long period of time. People with a more severe case of tuberculosis also may cough up blood.
People with the disease often have high body temperatures. They suffer what are called night sweats, during which their bodies release large amounts of water through the skin. TB victims also are tired all the time. They are not interested in eating. So their bodies lose weight.
One thing that is especially dangerous about TB is that people with moderate（中等的） signs of the disease may not know they have had it. They may spread the disease to others without even knowing it. So, it is very important for people to get tested for tuberculosis.The spread of the TB is through__________.
| A．food | B．air | C．clothes | D．touching |
Family members are those most at risk to be infected with the tuberculosis bacteria,_____________.
| A．because they have the same bath room | B．because they have blood relationship |
| C．because they love each other very much | D．because they live in the same room |
The common signs of TB are ___________.
| A．cough or even cough with blood, night sweat, and tired of sleeping. |
| B．cough or even cough with blood, night sweat, and eating too much |
| C．cough, fever, feeling tired, night sweat, losing weight |
| D．cough, fever, feeling tired, night sweat, eating too much |
Why may some TB patients spread the disease to others without even knowing it?
| A．Because there is no sign in the early stage of the disease. |
| B．Because these patients don’t show any signs of the disease. |
| C．Because these patients’ signs of the disease are too weak to be noticed. |
| D．Because these patients don’t know how the disease spreads between people. |
There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy, the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.
People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine, the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend(hurt) many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation. It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.
Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrong doings. They should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels. People who are unhappy ________ .
| A．always consider things differently form others |
| B．usually are affected by the results of certain things |
| C．usually misunderstand what others think or say |
| D．always discover the unpleasant side of certain things |
The underlined phrase “sour the pleasure of society” most nearly means “______ ”.
| A．have a good taste with social life | B．make others unhappy |
| C．tend to scold others openly | D．enjoy the pleasure of life |
We can conclude from the passage that ______.
| A．we should pity all such unhappy people |
| B．such unhappy people are dangerous to social life |
| C．people can get rid of the habit of unhappiness |
| D．unhappy people can not understand happy persons |
If such unhappy persons insist on keeping the habit, the author suggests that people should ______.
| A．prevent communication with them |
| B．show no respect and politeness to them |
| C．persuade them to recognize the bad effects |
| D．quarrel with them until they realize the mistakes |
In this passage, the writer mainly ______.
| A．describes two types of people | B．laughs at the unhappy people |
| C．suggests ways to help the unhappy | D．tells people how to be happy in life |
I arrived at my mother’s home for our Monday family dinner. The smells of food flew over from the kitchen. Mother was pulling out quilt(被子)after quilt from the boxes, proudly showing me their beauties. She was preparing for a quilt show at the Elmhurst Church.
When we began to fold and put them back into the boxes, I noticed something at the
bottom of one box. I pulled it out.“What is this?” I asked.
“Oh?” Mom said, “That’s Mama’s quilt.”
I spread the quilt. It looked as if a group of school children had pieced（拼凑） it together; irregular designs, childish pictures, a crooked line on the right.
“Grandmother made this?” I said, surprised. My grandmother was a master at making quilts. This certainly didn’t look like any of the quilts she had made.
“Yes, right before she died. I brought it home with me last year and made some changes,” she said. “I’m still working on it. See, this is what I’ve done so far.”
I looked at it more closely. She had made straight a crooked line. At the center of the quilt, she had stitched(缝) a piece of cloth with these words: “My mother made many quilts. She didn’t get all lines straight. But I think this is beautiful. I want to see it finished. Her last quilt.”
“Ooh, this is so nice, Mom,” I said. It occurred to me that by completing my grandmother’s quilt, my mother was honoring her own mother. I realized, too, that I held in my hands a family treasure. It started with the loving hands of one woman, and continued with the loving hands of another. Why did the author go to mother’s home?
| A．To see her mother’s quilts. |
| B．To help prepare for a show. |
| C．To get together for the family dinner. |
| D．To discuss her grandmother’s life. |
The author was surprised because ______.
| A．the quilt looked very strange. |
| B．her grandmother liked the quilt. |
| C．the quilt was the best she had seen. |
| D．her mother had made some changes |
The italic word “crooked” in the passage most probably means ______.
| A．unfinished | B．broken | C．bent | D．unusual |
Which of the following would be the best title for the passage?
| A．A Quilt Show | B．Mother’s Home | C．A Monday Dinner | D．Grandmother’s Quilt |
The World Trade Organization (WTO), founded on January 1, 1995, aims to encourage international trade to flow as possible, making sure that trade agreements are respected and that any disputes can be settled.
In the five years since its founding, the WTO has become well known as one of the world’s most powerful economic organizations, taking its place alongside the World Bank and International Money Fund.
The system of global rules for international trade, however, dates back half a century to 1948 when the General Agreement on Tariffs and Trade was formed after World War II.
As time went by, it became clear that the GATT had two major drawbacks-the limited areas of trade it covered, and the lack of an effective system to settle disputes.
After seven years of trade talks ending in 1994, the so-called Uruguay Round finally give birth to the WTO, complete with an effective system to settle disputes and new rules covering trade in services and intellectual property.
Even after seven years of talks and 22, 500 pages of agreements, there were still problems, especially the difficulty to deal with areas of agriculture and services, which the member nations agreed to revise in 2000. The WTO, with its head office in Geneva, has 135 members with 30 more waiting to join. From the passage we know that the GATT stopped working ________.
| A．soon after World War II ended |
| B．a little more than 50 years after World War II |
| C．just in the year 1994 |
| D．seven years before the Uruguay Round talk |
Compared with the GATT, the WTO _______.
| A．didn’t pay enough attention to services and intellectual property |
| B．got its members to sign the agreements more easily |
| C．has got to many areas of international trade to deal with to work effectively |
| D．can do better to settle disputes in more areas of international trade |
In the new century the WTO will ________.
| A．take the place of the World Bank and International Monetary Fund |
| B．have more members and settle more problems |
| C．make complete new rules in every area of international trade |
| D．have new rules covering trade in services and intellectual property |

As they migrate（迁移），butterflies and moths choose the winds they want to fly with，and they change their body positions if they start floating in the wrong direction．This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances．Scientists have long thought that insects were simply at the mercy of the wind．
Fascinating as their skills of flight are，migrating behavior has been difficult to study in insects because many long distant trips happthousands of feet above ground．Only recently have scientists developed technologies that can detect such little creatures at such great heights．
To their surprise，though，the insects weren’t passive travelers on the winds．In autumn，for example，most light winds blew from the east，but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes．
Even in the spring，when most winds flowed northward，the insects didn’t always go with the flow．If breezes weren’t blowing in the exact direction they wanted to go，the insects changed their body positions to compensate．Many migrating birds do the same thing．
The study also found，butterflies and moths actively flew within the air streams that pushed them along．By adding flight speeds to wind speeds，the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour．The findings may have real-world applications．With climate warming，migrating insects are growing in number．Knowing how and when these pests move could help when farmers decide when to spray their crops．
