Malaria, the world’s most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don"t (or can’t) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn’t kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease"s spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply a

nd are very expensive. If these drugs should fail, nobody knows what would come next.

Parents are often amazed at how fast their child grows and develops. New research has determined that the ability to quantify may develop much sooner than most parents realize.
Kristy Vanmarle, professor of the University of Missouri, has determined that contrary to what previous studies have shown, infants（婴儿）are able to quantify substances（物质）—like sand or water—as early as 10 months. As long as the difference between the two substances is large enough, infants will choose the larger amount, especially when it comes to food.
With the assistance of her team researchers, Vanmarle tested the quantifying skills of babies by presenting them with two cups: one containing a small amount of food, and one containing a larger amount. Consistently, the babies chose the larger amount.
“Several studies throughout the last 15 years have shown that infants are very good at telling how many objects they see; however, infants don’t seem to count things like water or sand,” Vanmarle said. “What we’re saying is that they can quantify substances; it’s just much harder. The infants can see how much food goes into each cup and compare that in their memories. They decide which amount is larger, and they almost always select the larger one.”
“This information further refutes（驳斥）the long-held idea that babies know nothing of the world,” Vanmarle said.
“Since psychologists have begun studying infants with sensitive measures, we’ve discovered a lot of early abilities. I think for parents, it should be exciting to know that there’s somebody in there that has some fundamental and basic knowledge of the world, and that knowledge is guiding their development,” Vanmarle said.
In the future, Vanmarle says this kind of study could be linked to a child’s progress in math-related skills, although programs marketed to increase those abilities, such as “Baby Einstein,” still have mixed reviews when it comes to academic study.

An inventor seeks to create a new product that serves a specific need and fulfills a role that other products do not. Sometimes an inventor comes up with a wholly new idea, but more often inventions are simply improvements on an older design. With a little imagination and creativity (创造力), an old idea can suddenly become something new.
However, creating a new invention means much more than having a brilliant idea. A good designer follows the design process: identifying the challenge, researching and brainstorming ideas(集思广益), designing a solution, testing and evaluating the ideas, and finally building the product. Designers also use science, math, technology, and engineering to design a tool that satisfies the need they identified.
Anyone can be an inventor —even kids! For example, Chester Greenwood was just fifteen years old when he invented a product that changed his life. In fact, his idea was so good that his invention supported him for the rest of his life. You may not know his name, but you probably know his invention —earmuffs (保暖耳罩)!
The inspiration for his earmuff design came to Chester when he was ice-skating. His ears were cold, and he decided to find a way to keep them warm. With the help of his grandmother, he made a new product to protect his ears and at the age of eighteen, Chester patented his earmuff design.
Many other famous inventors started young as well. Margaret Knight —the inventor of the flat-bottomed brown paper bag —is said to have created a safety device for textile looms(织布机) when she was just twelve years old. Another example is Thomas Edison, one of the greatest inventors in history, who applied for his first patent when he was just twenty-one years old. Over the course of his life, Thomas Edison patented a total of 1,093 inventions!
小题1: In most cases, an invention ________ according to the first paragraph.

A．comes from a complete new idea

B．is usually based on an old product or idea

C．will change its creator’s life completely

D．is created by scientists in different fields

小题2:The second paragraph mainly wants to tell us _______.

A．the difficulty in making a new invention

B．the common steps of creating new things

C．having a good idea is the key to creation

D．designing a tool is the first step in inventing

小题3:The example of Chester Greenwood is used to show that ________.

A．children can also invent something

B．it is easy even for children to make inventions

C．kids have more advantages in inventing things

D．to be an inventor is the best way to change one’s life

小题4:At first Chester designed his earmuffs in order to ________.

A．protect his ears while ice-skating

B．earn money to support his poor family

C．realize his dream of becoming an inventor

D．make himself look fashionable while ice-skating

I’ve been writing for most of my life. The book Writing Without Teachers introduced me to one distinction(区别)and one practice that has helped my writing processes tremendously. The distinction is between the creative mind and the critical mind. While you need to employ both to get to a finished result, they cannot work in parallel no matter how much we might like to think so.
Trying to criticize writing on the fly is possibly the single greatest barrier to writing that most of us encounter. If you are listening to that 5th grade English teacher correct your grammar while you are trying to capture a fleeting (稍纵即逝的) thought, the thought will die. If you capture the fleeting thought and simply share it with the world in raw form, no one is likely to understand. You must learn to create first and then criticize if you want to make writing the tool for thinking that it is.
The practice that can help you past your learned bad habits of trying to edit as you write is what Elbow calls “free writing.” In free writing, the objective is to get words down on paper non-stop, usually for 15-20 minutes. No stopping, no going back, no criticizing. The goal is to get the words flowing. As the words begin to flow, the ideas will come from the shadows and let themselves be captured on your notepad or your screen.
Now you have raw materials that you can begin to work with using the critical mind that you’ve persuaded to sit on the side and watch quietly. Most likely, you will believe that this will take more time than you actually have and you will end up staring blankly at the pages as the deadline draws near.
Instead of staring at a blank start filling it with words no matter how bad. Halfway through your available time, stop and rework your raw writing into something closer to finished product. Move back and forth until you run out of time and the final result will most likely be far better than your current practices.
小题1:When the author says the creative mind and the critical mind “cannot work in parallel” in the writing process, he means .

A．one cannot use them at the same time	B．they cannot be regarded as equally important
C．they are in constant conflict with each other	D．no one can be both creative and critical

小题2:What prevents people from writing on is .

A．putting their ideas in raw form	B．ignoring grammatical soundness
C．attempting to edit as they write	D．trying to capture fleeting thoughts

小题3:What is the chief objective of the first stage of writing?

A．To organize one’s thoughts logically.	B．To get one’s ideas down.
C．To choose an appropriate topic.	D．To collect raw materials.

小题4:One common concern of writers about “free writing” is that .

A．it overstresses the role of the creative mind	B．it does not help them to think clearly
C．it may bring about too much criticism	D．it takes too much time to edit afterwards

小题5:In what way does the critical mind help the writer in the writing process?

A．It allows him to sit on the side and observe.	B．It helps him to come up with new ideas.
C．It saves the writing time available to him.	D．It improves his writing into better shape.

Recreational tree climbing is taking root in the ecotourism industry, and it"s sending guys like Tim Kovar to far off reaches of the globe. Kovar, a tree-climbing instructor, recently returned to the U.S. from Brazil, where he spent time developing a tree-climbing operation thanks to the "slow travel" movement.
Slow travel, is like the slow food movement, the practice of giving fast food in favor of homegrown cooking—the kind that takes hours to prepare and enjoy. Likewise, slow travel urges visitors to experience a place"s natural surroundings and learn about the ecology in a way not afforded by extreme games.
"Tree climbing is a slow activity," says Kovar. "It"s not something you do quickly and then you"re on to the next thing or event." There is no such thing as a quick climb, especially for beginners. This wasn"t a race against the clock or the fellow climbers. In fact, tree climbing is unlikely to ever become a feature of the extreme games. Many climbers refuse competition. There has already been so much competition in the world.
"When you stand below

the tree, it can be amazing," Rusel DeMaria says, looking affectionately up at Michael"s Triumph, a 150-foot-tall tree. But reaching the treetop, he adds, is an entirely different feeling. Likewise, his wife, Viola Brumbaugh, kneels on the ground and asks Michael"s Triumph for permission to climb. "It goes a lot smoother that way, "She says.
And climbing has been included into many educational programs. New Tribe offers guided climbs through its school, Tree Climbing Northwest, where "we teach enough tree biology and forest ecology to raise awareness in our students," says New Tribe present Sophis Sparks. "We know that the tree climbing experience deepens personal appreciation for trees. After climbing, people value trees more and a

re motivated to support preservation. This is not just to preserve their playground."
Perhaps that is why he struggles with the term "recreational tree climbing," saying, "I prefer to call it inspirational tree climbing."
小题1:What do slow travel and the slow food movement have in common?

A．They take people a long time.	B．They are related to the eco-tourism industry.
C．They advocate protecting nature.	D．They cost people little money

小题2:What do we know about tree climbing from the passage?

A．People compete to see who can climb to the top first.

B．It favors the experience of enjoying nature.

C．It is a kind of extreme sport and needs a lot of effort.

D．People view it as a challenge to climb the tallest tree in a forest.

小题3:Brumbaugh kneels on the ground before climbing trees to ___________________.

A．beg for the safety of climbing	B．Expect to climb faster than her husband
C．Show respect for the tree	D．ask for permission of her husband

小题4:Sophia Sparks prefers the term "inspirational tree climbing" because it ____________.

A．provide people with more chances to play outside

B．bring a lot of pleasure to life

C．Deepens personal lo

ve between each other

D．Makes people realize they should protect trees

小题5:What"s the best title for the passage?

A．Tree-climbing travelling	B．Slow travel movements
C．Dangers of climbing	D．Respect for nature
