Once, a professor held a test on his students. The professor started with the following question, “Now, you are going to cut trees on a hill. One of the trees has a big while the other’s small. Which will you cut?” The question got a quick , “Of course the big one! No need to .”

The professor , “The big tree is a poplar（白杨） seen everywhere, while the small one is a Korean pine. Consider again?” A second brought students more sense: a Korean pine is much more than the poplar, so they changed their decision. “ we’ll cut the pine. The poplar isn’t worth our .” Smile still on the professor’s face. “But the pine’s trunk is less than the poplar.” Rather puzzled, they became , then said, “While, we’ll cut the poplar.” The professor gave more detail. “ the poplar is straight, the trunk became empty within. Then what’s your choice?”

Finally one of the students lost his and said, “Professor, you have asked a series of questions leading us to change our answers . What do you want to after all?”

The professor’s smile . He said, “Why none of you ask me for what purpose to cut the tree? Though my questions all the way, they are decided by one thing: your to take the action. If it aims at making handicraft articles you may cut the pine; if you just want to have some firewood, you’d better cut the poplar.”

Dear Jack,

Yours,

Back in 2003 an 86-year-old man drove his Buick through a crowded farmers’ market. Nine people were killed. More than fifty-four people were hurt, fourteen with serious injuries. When he finally stopped, the 86-year-old man got out his car and screamed at people to get out of the way. No alcohol or drugs were found in his system. Apparently, he was just old and confused.

This is a frightening accident, and it is not a rare one. There are many examples of elderly drivers driving into swimming pools, houses, storefronts, or worse.

In our teenage years, we all heard “driving is not a right; it’s a privilege.” That is still true, and there comes an age when driving is no longer a privilege that can be allowed. After a certain age, eyesight and dementia(痴呆) are very serious concerns. Undoubtedly, these age-related problems affect some older adults’ driving ability. By the time a person is between eighty-five and ninety years old, his or her driving privilege should be examined.

Licensing laws vary greatly from state to state, and it’s time for a national law on the maximum age limit for driving. The motivation for this law is safety. Another option is to start with laws that ban anyone over the age of eighty-five from driving after sundown, because driving conditions are not as safe as daylight hours. Still another option that may allow elderly drivers to continue driving could be new technology like a voice warning system that cautions drivers on busy streets or at traffic lights. Finally, since there are laws against driving under the influence of alcohol and drugs, shouldn’t some prescription drugs also be included? The average age of 85-year-old is undoubtedly taking at least one prescription drug daily.

The thought of an 86-year-old driver with failing eyesight running down the road in a two-ton piece of metal is unsettling to us all. Driving at an advanced age is not only challenging for the elderly drivers, but also it’s dangerous for the rest of us.

1.The first paragraph is written in order to show_________.

A. the harm of driving at an old age

B. the importance of traffic safety

C. traffic accidents are on the rise

D. many elderly drivers are careless

2.The author suggests that there should be new laws against driving __________.

A. over eighty-five

B. between sunset and dawn

C. with the help of voice warning systems

D. under the influence of prescription drugs

3.The underlined word “unsettling” in the last paragraph is closest in meaning to “________”.

A. disappointing B. worrying

C. touching D. interesting

4.Which of the following would be the best title for the text?

A. How to keep old people safe on the road?

B. Are drivers well protected by licensing laws?

C. Should there be an age limit for elderly drivers?

D. Is driving a right or a privilege for an old person?

The plants grown by Wageningen University researchers in Mars-like soil back in March have been analyzed and the results are excellent: at least four of the crops do not contain harmful heavy metal levels and are perfectly safe to eat, the University researchers report.

If you’ve seen The Martian, you can remember how much Matt Damon got done living off of his poo-powered crop of potatoes. It just goes to show how important it is for a long-term colony to be able to grow their own food locally. We’ve taken one step closer to that goal in March, when Netherlands’ Wageningen University reported that they’ve managed to grow ten different crops in Mars-like soil.

However, growing food doesn’t do us much good if eating it kills us, and researchers were worried that these crops contained dangerous heavy metals like lead or cadmium(镉) from the martian soil. But future colonists are delighted, as lab analysis of the crops determined that at least four of them are safe to eat.

Led by ecologist Wieger Wamelink, the team tested radishes, tomatoes, rye, and peas. They looked at cadmium, lead, aluminium(铝), nickel(镍), copper, chrome(铬), iron, arsenic(砷), manganese(锰), and zinc(锌) contents in the plants, and didn’t find any in dangerous levels. In fact, some of these vegetables have lower levels of heavy metals than those grown in regular potting soil. The plants were also tested for vitamins, alkaloids(生物碱), and flavonoids(类黄酮), with good results. While there are six more crops to test, Wamelink himself said that the results up to now are “very promising.”

“Growing food locally is especially important to our mission of permanent settlement, as we have to ensure sustainable food production on Mars. The results of Dr. Wamelink and his team at Wageningen University & Research are significant progress towards that goal,” said Mars One co-founder and CEO Bas Lansdorp in a press release.

A crowdfunding campaign is underway (and will be until the end of August) to fund the test of the remaining crops, potatoes included. If all the crops test out safe, with concentrations of heavy metal the FDA and the Dutch Food Agency consider as safe, Wamelink’s team will host a “Martian dinner” at the Wageningen greenhouse.

But I’ve seen the movie. Stay clear of the potatoes.

1.Which of the following is true according to the passage?

A. Four crops grown in martian soil have been tested safe to eat, with no heavy metals in.

B. The ability to grow food locally can ensure the permanent stay on Mars.

C. The team temporarily lack money to test the remaining six crops.

D. A “Martian dinner” will be hosted after all the remaining crops have been tested.

2.What is Bas Lansdorp’s attitude towards the research results?

A. Neutral.B. Indifferent.C. Unfavorable.D. Praiseful.

3.The author writes the passage in order to _________.

A. prove that it is practical to grow crops on Mars in the future

B. show crops grown in martian soil are safe for people to eat

C. point out the importance of growing food locally for long-term settlement

D. report the recent research findings of the possibility of growing food on Mars

How can we reduce the risk?

There are four general approaches to dealing with volcanic dangers. We can try to keep the danger from occurring - often an impossible task. We can try to change its path or reduce its impact on existing development. We can take steps to protect future development. We can also do our best to have disaster response plans in place before they are needed.

Removing the Threat

Clearly, there is no way to stop an eruption. We can, however, attempt to reduce the eruption’s effects by strengthening structures, for example, building protective works such as walls to make lava(熔岩) flow away from developed areas. Such efforts can be and have been successful, but are of limited use in a large-scale eruption.

Planning for the Future

Protecting future development from volcanic dangers is a simple task. Before building houses, we should judge the risk. If the risk seems too great, a safer location should be found. This type of planning is very effective, but all too often, people are drawn to the lush(葱郁的)，rolling land of a quiet volcano.

Disaster Preparedness

When a volcano comes to life, a few weeks may not be enough time to avoid a tragedy. Planning is the key to saving lives. Well before the warning signs occur, people must be educated about volcanic dangers. Escape plans must be in place. Communication between scientists, officials, the media, and the general public should be practiced. Emergency measures must be thought out and agreed upon.

If you doubt the importance of these efforts, take another look at past volcanic tragedies, such as the eruption of Nevado del Ruiz. Communication failures left the town of Armero unprepared for escape. When a deadly mudflow came down the slope(斜坡), 21,000 people--90 percent of the town’s people--died.

1.The passage is intended for ________.

A. the general public B. architects

C. adventurers D. geographers

2.When building houses, people tend to ________.

A. judge volcanic dangers carefully

B. take volcanic dangers seriously

C. live near a quiet volcano

D. find a safer place far away from a volcano

3.The writer mentioned Nevado del Ruiz to prove ________.

A. The failure to keep volcanic dangers from happening

B. The importance of preparing for a volcanic eruption

C. The bravery of the people in Armero Town

D. The uncertainty of volcano’s damage

The relationship between exercise and cancer has long both intrigued and puzzled oncologists and exercise physiologists.

Exercise is strongly associated with lowered risks for many types of cancer. At the same time, exercise involves biological stress, which typically leads to a short-term increase in inflammation(发炎) which can contribute to higher risks for many cancers.

Now, a new study in mice may offer some clues into the exercise-cancer paradox. It suggests that exercise may change how the immune system deals with cancer by boosting adrenaline（肾上腺素）, certain immune cells and other chemicals that, together, can reduce the severity of cancer or fight it off altogether.

To try to better understand how exercise can both elevate inflammation and simultaneously protect the body against cancer, scientists at the University of Copenhagen in Denmark and other institutions decided to closely examine what happens inside mice at high risk for the disease.

So, for the new study, they began by gathering a group of adult lab mice. These animals generally like to run.

The scientists then implanted melanoma (黑素瘤) skin cancer cells into the mice before providing half of them with running wheels in their cages while the other animals remained sedentary. After four weeks, far fewer of the runners had developed full-blown melanoma than the sedentary mice and those that had been diagnosed with the disease showed fewer and smaller lesions.

They drew blood from both the exercising and sedentary animals and cells from any tumors in both groups. As expected, they found much higher levels of the hormone adrenaline in the blood of the exercising animals, especially right after they had been working out on the wheels but also at other times of the day. The body releases adrenaline in response to almost any type of stressful experience, including exercise.

They also found higher levels of interleukin-6 in the blood of the runners. This is a substance that is released by working muscles and is believed to both increase and decrease inflammation in the body, depending on where and how it goes to work.

Perhaps most important, they found much higher numbers in the bloodstreams of runners than in the sedentary mice of a type of immune cell named natural killer cells that are known to be strong cancer fighters.

So the scientists repeated their original experiment multiple times, inducing cancer while allowing some mice to run and others to sit. In some of these follow-up experiments, the scientists injected the runners with a substance that blocked the production of adrenaline and gave sedentary animals large doses of added adrenaline.

What they now found was that when running mice could not produce adrenaline, they developed cancer at the same rate as the sedentary animals, while the sedentary animals that had been injected with extra adrenaline fought off their tumors better than other sitting mice.

More remarkably, the scientists determined that adrenaline seemed to be sending biochemical signals to some of the animals’ IL-6 cells, making them physiologically more alert, so that when a tumor began to develop in the affected animal, those IL-6 cells in turn activated the natural killer cells in the bloodstream and actually directed them to the tumors, like minute guide fish.

With these results, “we show that voluntary wheel running in mice can reduce the growth of tumors, and we have identified an exercise-dependent mobilization of natural killer cells as the underlying cause of this protection,” said Pernille Hojman, a researcher at the University of Copenhagen who oversaw the new study. It perhaps provides one more incentive for us to get up and move.

1.In the first experiment, which one is the most important result the scientists found?

A. Natural killer cells are much more in the bloodstreams of runners than in the sedentary mice.

B. Levels of interleukin-6 are higher in the blood of the runners than in the sedentary mice.

C. Exercise such as running seemed to help the mice fight against the cancer.

D. Adrenaline can reduce the severity of cancer or fight it off.

2.In the follow-up experiments, the scientists found ________.

A. the hormone adrenaline has much higher levels in the blood of the exercising animals

B. how these elements in the runners — their increased adrenaline, IL-6, and natural killer immune cells fight against tumor

C. interleukin-6 can both increase and decrease inflammation in the body, depending on where and how it goes to work

D. what happens inside mice at high risk for the disease

3.According to the study, we can infer the fundamental substance to fight the cancer off is ________.

A. adrenalineB. interleukin-6

C. natural killer cellsD. genes
