Scientists say the olinguito is the first new carnivore(食肉动物)discovered In the Americas in more than 30 years. It is a hairy orange-brown creature with a sweet face and big eyes The animal has small. rounded ears and lives in the trees An adult weighs one kilogram and measures about 75 centimeters. with half of those centimeters taken up by its ringed tail Most of the time. it likes to eat fruit, although it also eats meat. Active at night, the animal has lived in Colombia and Ecuador for a long time. But the olinguito did not exist in science books before now.
Kristofer Helgen, director at the National Museum in Washington, led the research team that confirmed the existence of the olinguito. It had been mistaken more than a century ago for a look-alike animal -- a similar but larger olingo(尖吻浣熊). Mr. Helgen had been studying olingos in a museum for ten years. At that time. he observed a difference in the size and shape of the heads and teeth. That led him on an effort to prove he was looking at an animal never before described by science. He got lucky when he communicated with a zoologist in Ecuador. The animal expert there made a short video that shows an olinguito in the trees. The video confirms that the oiinguito is different from the olingo Mr. Helgen says tens of thousands of olinguitos live in the wild and are not in danger of disappearing forever. Human beings, however, are moving closer to the olinguito habitat in the Andean cloud forests. The research team estimates that 42 percent of historic olinguiio habitat has been removed

That American high schools lavish more time and money on sports than on math is an old complaint. This is not a matter of how any given student who plays sports does in school, but of the culture and its priorities. This December, when the latest Program for International Student Assessment(PISA) results are announced, it’s safe to predict that American high-school students will once again display their limited skills in math and reading, outscored not just by students in Poland but also by students in places like South Korea, Belgium, the Netherlands, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.
Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D.C., which costs thirty thousand dollars a year. The tour leader—a mother with three children in the school—was asked about the school’s flaws. When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really?” one of them asked worriedly, “What do you mean?”
One of the ironies of the situation is that sports reveal what is possible. American kids’ performance on the field shows just how well they can do when expectations are high. It’s too bad that their test scores show the same thing.
小题1:Tom decides to spend his senior year in Poland because _______.
A.he intends to improve his scores |
B.Polish kids are better at learning |
C.sports are not supported at schools in Gettysburg |
D.there are striking differences between the 2 countries |
A.PISA plays a very important role in America |
B.little time is spent on sports in Japanese schools |
C.American high schools complain about sports time |
D.too much importance is placed on sports in America |
A.low expectations result in American students’ poor PISA performance |
B.high expectations push up American students’ academic performance |
C.American students’ academic performance worries their parents a lot |
D.lacking practice contributes to American students’ average performance |
A.compare Polish schools with those in America |
B.call on American schools to learn from the Polish model |
C.draw public attention to a weakness in American school tradition |
D.explain what is wrong with American schools and provide solutions |
Succession occurs because plants and animals cause a change in the environment in which they live. The first weeds and grasses that appear on a bare field, for example, change the environment by shielding the soil from direct sunlight. As these plants spread, the ground becomes cooler and more moist than it was originally. Thus, the environment at the ground surface has been changed. The new surface conditions favor the sprouting(产生)of shrubs. As shrubs grow, they kill the grasses by preventing light from reaching them and also enhance (增加)the soil. Pine seedlings (苗)soon take hold and as they grow, they in turn shade out the shrubs. They are not able to shade out oak and hickory (山核桃)seedlings, however, that have found the forest floor suitable. These seedlings grew into large trees that eventually shade out the pines.

A.The Importance of Weeds and Grasses |
B.The Success of Oak and Hickory |
C.How Environmental Habitats Change |
D.Animal and Plant Habitats |
A.oak and hickory trees grow taller than pines |

If blood is red, why are veins (静脉) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it"s outside the body, when it"s sitting in a vein near the surface of the skin, it"s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
Which works harder depends on whether you are busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don"t they grow back in grown-ups?
Baby (or "milk") teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you"re done. When they"re gone, they’re gone. This is because nature figures you"re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn"t because they"re shrinking all over. They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity. Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don"t really shrink! It is not that they are growing backwards — their legs, arms and backbones getting shorter. When they do get shorter, it"s because the spine has shortened a little or, more often, become more bent and curved.
Why does spinning(旋转) make you dizzy (眩晕的)?
Because your brain gets confused between what you"re seeing and what you"re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you"re moving while you"re not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s "use it, or lose it”! It"s not that exercise makes you healthy; it"s more that a lack of exercise leaves your body weak and easily affected by disease.
小题1:What is the color of blood in a vein near the surface of the skin?
A.Blue. | B.Light yellow. | C.Red. | D.Dark reddish purple. |
A.Because their spine is in active use. |
B.Because they are more easily affected by gravity. |
C.Because they keep growing backwards. |
D.Because their spine becomes more bent. |
A.In the long run, our brain probably works harder than our heart. |
B.When our brain senses the spinning, we will fell dizzy. |
C.The brains of the other mammals are as complex as those of humans. |
D.Our feelings and emotions come from the most developed area in our brain. |
A.To give advice on how to stay healthy. |
B.To provide information about our body. |

D.To report the latest discoveries in medical science. |
The first regularly published newspaper in English was printed in Amsterdam in 1620. In 1621, an English newspaper was started in London and was published once a week. The first daily English newspaper was the Daily Courant, which came out in March 1702.
In 1690, Benjamin Harris printed the first American newspaper in Boston .But not long after it was first published, the government stopped the paper. In 1704, John Campbell started the Boston Newspaper, the first newspaper published daily in the American colonies(殖民地). By 1760, the colonies had more than thirty daily newspapers.There are now about 1, 800 daily papers in the United States.
Today, as a group, newspapers in English have the largest circulation (发行量)in the world .But the largest circulation for a newspaper is that of the Japanese newspaper Asahi Shimbun . It sells more than eleven million copies every year.
小题1:The first regularly printed European newspaper started in ________.
A.Rome in 59 BC | B.Germany in 1609 |
C.Amsterdam in 1620 | D.England in 1621 |
A.1620 | B.1621 | C.1590 | D.1702 |
A.History of newspapers |
B.History of daily newspapers |
C.The beginning of newspapers |
D.On reading newspapers |
Since natural evolution is extremely slow and mankind’s selective production programs only take a few generations to produce a completely new species, natural evolution has already taken a back seat to mankind’s production programs. In addition, mankind has successfully killed off several species all together. For example, there are no more European wolves in existence and mammoths (猛犸象) probably died out because of mankind. Even certain diseases have been permanently got rid of from the planet, and dozens of other diseases will soon be too. Again, natural evolution did i»t cause most of the destruction during man’s rule of the world.
Currently, scientists are creating new species with desired characteristics in the lab significantly faster than natural evolution creates new species. In a single generation, new species can be created and destroyed by mankind, while natural evolution could take thousands of years to do the same but only accidentally. Scientists are even able to replace defective (有缺陷的) or damaged genes with different genes to attempt to cure genetic defects. This is something that natural evolution could possibly never correct.
Eventually scientists will even be able to improve the quality of people. For example, imagine not only correcting your eyesight with gene treatment, but also ensuring that all of your children do not receive your old genes of poor eyesight too. Scientists will one day be able to improve the memory and intelligence of your children, so that they will do better in school and achieve more in life. Doctors and scientists will be able to customize (订制) babies before they are born just like picking options at a car store.
小题1:According to the first paragraph,______ .
A. man-made evolution has improved all species
B. man-made evolution has weakened some species
C man-made evolution can make up for all natural losses
D. natural evolution won’t happen without man’s assistance
小题2:What does the underlined part “taken a back seat to” in Paragraph 2 mean?
A. Become powerful assistance to.
B. Become a huge barrier to.
C Speeded up the process of.
D. Played a less important role than.
小题3:What does the third paragraph mainly talk about?
A.Why natural evolution happens so slowly. |
B.The way scientists adopt to have genetic defects repaired. |
C.The advantages of man-made evolution over natural evolution. |
D.How scientists make use of man-made evolution to create new species. |
A.Near-sighted parents will be able to produce babies with good eyesight in the future. |
B.Doctors and scientists will be responsible for mass production of babies in the future. |
C.It is natural evolution that is to blame for the destruction of European wolves and mammoths. |
D.Children can now have their memory and intelligence improved with the help of gene treatment. |
