It is sometimes said that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified Flying Objects (UFO). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe. Some have been explained in scientific ways. Others have never been explained. Here is an account of UFOs from a report.
Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night.
“It wasn’t the moon ”, was the reply.
They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn’t smoke because it didn’t change its shape. It was moving in a regular way. That is to say, it didn’t go suddenly faster or more slowly, and it didn’t go higher or lower. So the two men decided that there must be men in it.
After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness.
When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast.
On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken?

Some scientists warn that ice near the Earth’s Poles may indeed be melting. This “polar meltdown” may be the first sign that the Earth is heating up. We could be in very serious trouble if this trend continues. It is estimated that a meltdown of as little as 10 percent of Antarctica’s ice would raise sea levels around the globe by 4 to 9 meters. Floods would cover low-lying regions and turn coastal cities like New York and New Orleans into real life underwater world.
Scientists first predicted in the 1970s that heat trapped in the Earth’s atmosphere could cause a polar meltdown. Many now believe that human activities are turning up the heat. When we burn fossil fuels like coal and oil, we add carbon dioxide(CO2) gas to the Earth’s atmosphere. Cutting down trees also makes CO2 levels raise because trees normally soak up CO2 to make food. Scientists say higher CO2 levels strengthen the “greenhouse effect” and could increase the Earth’s temperature. In fact, CO2 levels have risen by 30 percent since the Industrial Revolution of the 18th and 19th centuries.
Over the past three years, satellite measurements have shown a sea level rise of about a quarter inch worldwide. “If nothing is done to reduce fossil-fuel pollution and global warming, sea levels will rise even more.” says geologist Richard Alley.
But even Alley admits that a polar meltdown would take time. The ice in Antarctica and Arctic locks up nearly nine times the volume of water contained in all the world’s rivers and lakes. These are such big “ice cubes” and it would probably take thousands of years to melt them.
Another scientist Charles Bentley doesn’t think a meltdown will happen at all. “Even if warmer temperatures begin to melt polar-ice,” he says, “the excess moisture would most likely be redeposit as snow.” In other words, the melted ice would evaporate into the atmosphere, refreeze, and fall as rain and snow over the Poles.
小題1:What consequence of global warming is mentioned in the passage?
A.More tropical storms.B.More tropical diseases.
C.Changes in farm productivity.D.Coastal flooding.
小題2: Which of the following statements does the second paragraph support?
A.CO2 in the atmosphere cannot keep the heat from escaping into space.
B.The increase of CO2 gas may warm the planet and help to melt polar ice.
C.Cutting down trees helps to greatly reduce CO2 levels.
D.The end of the short-lived age of fossil fuels is already in sight.
小題3: Geologist Richard Alley most likely agrees that _______.
A.the sea-level rise can be prevented by cutting back on energy-consuming activities
B.the recent breaking off of ice blocks from Antarctica is just a natural part of a long-term cycle
C.Antarctica temperatures have significantly changed since the Industrial Revolution
D.the polar meltdown may be an accidental change of climate rather than a sign of global warming
小題4:Charles Bentley believes that a polar meltdown will not occur because _______.
A.governments around the world are beginning to reduce CO2 levels in the air
B.a(chǎn) melting of the polar ice cannot be achieved with the present technologies
C.the melted ice in the polar areas would change into snow and rain over the Poles
D.the sun’s heat would have no chance of being absorbed by the polar ice
小題5:In which paragraph does the author mention the immense quantities of polar ice?
A.In the second paragraph.B.In the third paragraph.
C.In the fourth paragraph.D.In the fifth paragraph.

Petroleumis a very important mineral. It gives us heat and light. It gives us power for our cars, planes, and ships. Also, it gives us power for machines of all kinds.
How is petroleum formed? Scientists believe petroleum comes from the remains of plants and animals (Remains are what is left after a plant or animal has died.)
What exactly is petroleum? Petroleum is a mineral that is a mixture of hydrocarbons. It is an oily liquid, which may be brown, green, or black in colors. The word “petroleum” comes from Greek. It means “rock oil”.
Crude (天然的, 未加工的) oil is petroleum that comes directly from deep in the ground. It is then taken to a refinery. a refinery is a kind of factory to refine oil. At a refinery the crude oil is separated into many parts. From the refined petroleum we get important things, such as gasoline, kerosene, fertilizer, detergents and a lot of other useful things. In fact, there are thousands of such things that we can get. Petroleum really is of great value!

An annoying problem for humans, who like to boast (夸耀) about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses. The inside of the earth is relatively close, but how can we get there?
The deepest oil well enters a mere six miles into the crust (地殼) (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle (地幔). Sadly the project involved government supporting.
It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust ---  about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible.
What little we know about the inside of the earth (like the fact that there's a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes.
So maybe it's time for a thorough new method to explore the earth's inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack (裂縫).
Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he'd pour a few hundred thousand tons of molten (熔化的) iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface.
Stevenson compares his idea to space exploration. "We're going somewhere we haven't been before,"he says. "In all possibility, there will be surprises.”
This idea can probably be put in the drawer marked with Isn't Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson's idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.
小題1:Going inside the earth is _____ than going into space.
A.more interestingB.more possibleC.easierD.more challenging
小題2:How deep have we gone into the earth until now?
A.6 miles.B.4,000 miles.C.7.5 miles.D.25 miles.
小題3:Which of the following is TRUE about David Stevenson's idea?
A.It is an inspiring but not practical idea now.
B.It is a practical proposal that has come into use now.
C.It is a good proposal that will soon be put into practice.
D.It is a false theory that cannot be carried out at all.
小題4: What might be the most suitable title for the text?
A.An Annoying Problem for Humans
B.To the Center of the Earth

A recent study conducted by the Pine Street Foundation showed that a dog’s nose may have the ability to detect cancer. A dog’s nose, which was the “medical device” used as part of the research, is believed to be among the world’s most powerful olfactory(嗅覺的) sensors. The study was conducted with 169 subjects 55 of which had been diagnosed as having lung cancer, 31 have breast cancer and 83 control subjects——people without cancer. During the study, five professionally trained scent dogs were used to distinguish between the breath samples of cancer patients and those who were healthy. With an average of 90% accuracy, the research was deemed a success.
The Pine Street Foundation conducted its research on the belief that cancer cells give off a different type of metabolic(新陳代謝) waste product than normal cells. According to the study, the difference is so great that it can be detected by a dog’s sense of smell, including both early and late stages of the disease.
In the conclusion of the study the Pine Street Foundation said that even ordinary dogs may be trained to identify the presence of cancer with only a breath sample. The organization also said that dogs can recognize the disease with astonishing amount accuracy and, finally, that the dog’s detection was not hindered(妨礙) by the presence of age, smoking or stage of cancer.
The Pine Street Foundation plans to continue their research and is currently seeking funding to launch new studies.
小題1:If we want to add several different detecting examples to the passage, we should write them
__________.
A.between paragraph 1 and paragraph 2B.between paragraph 2 and paragraph 3

The storage of classified (分類的) research at all 24 labs run by the US Department of Energy was shut down this week after officials decided that the security (安全) problems recently found at the Los Alamos National Laboratory in New Mexico might also exist elsewhere.
Several computer disks went missing at Los Alamos earlier this month, forcing Energy Secretary Spencer Abraham to stop all work at the lab until the problems are found out. As of 26 July, two missing disks had still not been found, and 15 employees had been suspended in connection with the disappearance.
Now all energy labs will stop doing classified research that involves(需要) removable storage devices --- such as computer disks ---  until all the devices are given explanation for and new procedures are in place for monitoring their handling by laboratory employees.
"While we have no evidence that the problems being investigated are present elsewhere, we have a responsibility to take all necessary action to prevent such problems, "Abraham said on 23 July.
The shut-down isn't quite as dramatic(驚人的)as it sounds, experts say. Only two labs will be seriously affected: Sandia National Laboratories in Albuquerque, New Mexico, and Lawrence Livermore National Laboratory in  California. Together with Los Alamos, these two labs conduct the most part of the country's nuclear weapon programmes. At Livermore, 876 employees will be suspended during the storage of some 12,000 items of classified removable material.
At other labs, far fewer people will be affected. "The impact (影響) should be the smallest," says Martha Krebs, former director of the energy department's science office.
小題1:Why was the storage of classified research at all 24 labs shut down?
A.Because the security problems might be present elsewhere.
B.Because the security problems existed elsewhere.
C.Because two missing computer disks had still not be found.
D.Because officials decided to stop doing such research.
小題2:How many labs conduct the country's nuclear weapon programmes according to the text?
A.About 24.B.Only 2.C.More than 2.D.Over 15.
小題3:The underlined word "suspended"in the second paragraph probably means "______”.
A.hung from aboveB.stopped from holding a positionC.doubtedD.fired
小題4: It can be inferred from the text that _____.
A.the computer disks must have been stolen by terrorists
B.the people living in the United States have little security
C.the United States is a country whose security is very bad
D.the missing of the computer disks caused great fear among Americans

Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back.. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛蟲) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for
instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single experience with this kind of plant will teach an animal to stay away from it in the future.
小題1:The holly plant has more spines on the lower leaves because most animals________.
A.a(chǎn)re not tall enoughB.like the lower leaves only
C.a(chǎn)re not clever enoughD.can get the lower leaves easily
小題2:To defend themselves, oak trees use________.
A.chemical meansB.physical means
C.bitter chemicalsD.sandy materials
小題3:How does tobacco protect itself against an attack from a caterpillar?
A.Its leaves fight against the attack by physical means.
B.Its roots send a messenger to discourage the caterpillar.
C.Its roots increase the production of nicotine when it is attacked.
D.Its leaves produce poisonous sand to drive the caterpillar away.
小題4:What would be the best title for this passage?
A.Plants and AnimalsB.How Plants Defend Themselves
C.Attacks and DefensesD.How Animals Eat Plant Leaves

Early people had very little effect on the environment. They lived in caves in very small “clan” groups. They collected or killed only enough for the clan’s survival. Early clans were nomadic, which mean that they didn’t stay in one place. Instead, they moved around, following the animals that were their main food source and seeking areas where seasonal plants grew wild. Moving around seasonally helped to protect the environment. The land had time to recover and animals had time to breed (繁殖)before the clan returned for the next season..
As time went by, these small family clans joined with others to form larger groups for protection. Joining with other clans gave them more hunters and more women to help cut up the meat and share it between families. Eventually, people tamed(馴養(yǎng))wild animals such as dogs and horses. People settled around rivers and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to areas where the plants grew. This development changed the environment.
Traditional forms of work also changed. Some people were better at performing a particular task than other clan members, so then began to specialize in things they were good at doing. This also meant that they began to exchange their goods for things that others produced.
People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals were transported to places where they had not existed before. Specialization also give people more free time. So art ,dance and music became important ways of expressing feelings and thoughts. This was how many great civilizations started.
Compared to the past, modern civilization has experienced many changes to become the highly developed society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions and technology have made work easier.
However, pollution and other serious problems have also resulted from human progress. As concerned citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.
小題1:Early tribes didn’t have much effect on animal population because_____
A .they kept animals for themselves         B they ate only vegetables
C they loved animals                     D they killed only enough for food
小題2:The main purpose for small clans to join together was_____
A to hurt animals                         B to seek safety
C to share caves                         D to protect environment
小題3:According to the passage ,we can learn that_____
A early people moved to new places looking for new sources of food
B modern civilization began when people started to live together in big groups
C modern advancements are always good for the environment
D people began to exchange goods because they didn’t have enough money
小題4:It can be concluded from the passage that_____
A human progress has brought civilization to the society
B civilization has improved traditional forms of work
C early people understood environmental protection
D our environment has been affected by human progress
