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

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.

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. |
For many centuries, people used windmills to grind(碾碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost. Today, there is a global movement to supply more and more of our electricity through the use of wind.

C.The worldwide movement to save energy. |
D.The global trend towards producing power from wind. |
When it comes to sleep temperature, experts recommend following the principle: not too cold, not too hot, but just right. “People seem to sleep best at temperature between 62 and 70 degrees F,” says Dr. Alice Hoagland. When the surrounding temperature falls too low, it can rouse you from sleep. A good blanket helps drive the coldness away.
At the other extreme, overheating yourself can affect your sleep as well. “Core body temperature typically drops during the first four hour’s of sleep,” says Dr. Hoagland. This decline in body temperature helps you fall asleep and stay asleep.
“In medical care, weighted blankets are one of our most powerful tools for helping people who are anxious, upset, and possibly losing control,” says Dr. Karen Moore. These special blankets are filled with weighted pellets. Weighted blankets are also marketed for general use as an aid to sleep and relaxation. Like a firm hug, weighted blankets help us feel safe.” This is the reason why many people like to sleep under a blanket even in summer.
“If you want to try this type of blanket, the best weight depends on your body size and personal preference. However, 15 to 30 pounds is typical for adults,” Moor says. She adds that weighted blankets are not recommended for those recovering from surgery.
“People can also have serious preferences for a particular blanket,” says Dr. Hoagland. “Regularly using a favorite blanket for sleep can help to develop a conditioned response so that sleep is quicker.” In fact, many sleep centers ask patients to bring their own blanket and pillow from home, which helps them fall asleep more easily.
小题1:The author wrote the passage mainly to tell us _____.
A.the importance of blankets |
B.how to choose the perfect blanket |
C.different materials used to make blankets |
D.the history and usage of blankets |
A.wake up | B.take up | C.make up | D.pick up |
A.Body temperature rises when we fall asleep |
B.The perfect sleep temperature should be above 70 degrees F. |
C.Weighted blankets should be at least 30 pounds. |
D.People are advised to use their own blankets. |
Electricity, water, gas and telephone may not be working after an earthquake. The police and fire department are likely to be tied up. You should be prepared to take care of yourself for at least three days, preferably for a week.
This list can also be applied to other disasters, such as floods or wildfires.
1. food and water (a gallon a day per person)
2. a first aid kit
3. a fire extinguisher suitable for all types of fires
4. flashlights, a portable radio extra batteries
5. blankets, clothes, shoes and money (ATMs may not work)
6. baby and pet food
It’s also a good idea to decide beforehand how and where your family will reunite if separated during a quake and to conduct in-home practice drills.
During an Earthquake
If you are indoors, stay there. Get under and hold onto a desk or table, or stand against an interior wall. Stay away from exterior walls, glass, heavy furniture, and stay away from windows and outside walls and do not use the elevator.
If you are outside, get into the open, stay into the open, stay away from buildings, power lines or anything else that could fall on you.
If you are driving, move the car out of traffic and stop, avoid parking under or on bridges or overpasses, Try to get clear of trees, light posts, signs and power lines.
If you are in a crowded public place, avoid panicking and do not rush for the exit. Stay low and cover your head and neck with your hands and arms.
After an Earthquake
If the phone is working, only use it in case of emergency. Likewise, avoid driving if possible to keep the streets clear for emergency vehicles.
Be aware that items may fall out of cupboards or closets when the door is opened, and also that chimneys can be weakened and fall with touch. Check for cracks and damage to the roof and foundation of your home.
Listen to the radio for important information and instructions. Remember that aftershocks, sometimes large enough to cause damage in their own right, generally follow large quakes.
If you leave home, leave a message telling friends and family your location.
小题1:Which of the following items is unnecessary to prepare before an earthquake?
A.Batteries | B.Cash | C.Medicine | D.Creditcard |
A.hideyourselfinthekitchen |
