A new American weather satellite could save more lives by better predicting extreme weather conditions. It will be in orbit(轨道）some 36,000 kilometers above Earth’s surface. The National Oceanic and Atmospheric Administration, also known as NOAA, has been working with the National Aeronautics and Space Administration (NASA) on the project.
NOAA officials are calling the new satellite GOES-R. That is short for a much longer name—the Geostationary Operational Environmental Satellite-R Series. NOAA said GOES-R could improve the nation's ability to observe weather conditions and make weather predictions. It said the satellite's operation would lead to more exact and timely weather forecasts watches and warnings.
The government agency said the satellite will require testing of its six instruments and will be ready to work “within a year."
"The next generation of weather satellites is finally here." said NOAA Administrator Kathryn Sullivan. She described GOES-R as one of the most complicated Earth-observing machines ever created. Sullivan said its instruments will be able to study Earth five times faster and with four times more detail than any other NOAA satellite currently in operation. She believes this will make the United States an even stronger, more “Weather-Ready" nation.
A NOAA statement said the greater detail will help improve the agency’s study of ocean storms, as well as “the prediction and warnings of severe weather. "In addition, GOES-R will be able to provide improved rainfall estimates (预计), which will lead to more timely and detailed flood warning. The statement also said that GOES-R will give better estimates of wind strength, as well as better measurement of fog, ice or lightning strikes.
Craig Fugate serves as administrator of the Federal Emergency Management Agency. He says that the GOES-R satellite will improve the ability of people and organizations across America to prepare for, and react to, weather-related disasters.

A new American weather satellite could save more lives by better predicting extreme weather conditions. The satellite was launched in the state of Florida on November 19, 2016. The National Oceanic and Atmospheric Administration, also known as NOAA, has been working with the National Aeronautics and Space Administration (NASA) on the project.
NOAA officials are calling the new satellite GOES-R. That is short for a much longer name the Geostationary Operational Environmental Satellite-R Series.
NOAA said GOES-R could improve the nation’s ability to observe weather conditions and make weather predictions. It said the satellite’s device would lead to more exact and timely weather forecasts, watches and warnings.
The government agency said the satellite will require testing of its six instruments and will be ready to work “within a year.” One of the six instruments on the satellite is designed to help scientists study lightning strikes and map them. This, NOAA says, will help the agency follow the movement of severe storms and provide more detailed warnings.
“The next generation of weather satellites is finally here,” said NOAA Administrator Kathryn Sullivan. She described GOES-R as one of the most effective Earth-observing machines ever created. Sullivan said its instruments will be able to study Earth five times faster and with four times more details than any other NOAA satellite currently in operation. An NOAA statement said the greater detail will help improve the agency’s study of ocean storms, as well as “the prediction and warnings of severe weather.” In addition, GOES-R will be able to provide improved rainfall estimates, which will lead to more timely and detailed flood warnings.

Satellites(卫星) are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to us through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．
We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator（赤道）．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit（轨道），So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash（撞）into each other．
1.Which of the following is NOT done by satellites according to the passage?
A.Sending information for weather forecast．
B.Taking photographs of the Earth．
C.Sending TV pictures．
D.Providing food for airplane pilots．
2.What’s the speed the earth rotates at?
A.35,880 kilometers per hour．
B.335,880 kilometers per hour．
C.11,000 kilometers per hour．
D.110,000 kilometers per hour
3.Why does the satellite move around the world at the same speed as the Earth rotates?
A.In order to take photographs．
B.In order to stay in a certain position in the orbit．
C.In order to move away from its orbit．
D.In order to send television pictures．
4.What does the underlined word “This” in the 3rd paragraph refer to?

Air pollution shortens human lives by more than a year, according to a new study from a team of leading environmental engineers and public health researchers. Better air quality could lead to a significant extension of lifespan(寿命) around the world.
It is the first time that data on air pollution and the lifespan has been studied together in order to check how air pollution affects overall life expectancy.
The researchers looked at outdoor air pollution from particulate matter (PM)(颗粒物) smaller than 2.5 microns. These particulates can enter deep into the lungs, and breathing PM 2.5 is associated with the increased risk of heart attacks, strokes and cancers. PM 2.5 pollution comes from power plants, cars and trucks, fires, agriculture and industrial emissions(排放物).
Led by Joshua Apte, the team used data from the Global Burden of Disease Study to measure PM 2.5 air pollution exposure and its consequences in 185 countries. They then quantified the national impact on life expectancy for each individual country as well as on a global scale.
“The fact that air pollution is a major global killer is already wellknown,” said Apte. “And we all care about how long we can live. Here, we were able to systematically identify how air pollution shortens lives around the world. What we found is that air pollution has a very large effect on survival — on average about a year globally.”
In the context of other significant phenomena negatively affecting human survival rates, Apte said this is a big number. “For example, it’s considerably larger than the benefit in survival we might see if we found cures for both lung and breast cancer combined,” he said. “In countries like India and China, the benefit for elderly people of improving air quality would be especially large. For much of Asia, if air pollution were removed as a risk for death, 60yearolds would have a 15 percent to 20 percent higher chance of living to age 85 or older.”
1.What do we know about PM 2.5?
A.It has a bad effect on human health. B.It will be controlled in the future.
C.It only comes from industrial emissions. D.It spreads to the world from Asian countries.
2.What did the researchers do to study how air pollution affects the lifespan?
A.They collected accurate information from all the Asian countries.
B.They employed the research data to calculate the effect.
C.They studied the disease and lifespan together time and time again.
D.They measured particulate matter much more carefully than before.
3.What can be inferred from the text?
A.The key to people living longer is good air quality.
B.People think air pollution is the most dangerous killer to them.
C.Apte will agree that people should take action to deal with air pollution.
D.Factories should decrease the production of cars to stop air pollution.
4.What is the best title for the text?
A.The Way Human Beings Enjoy a Longer Lifespan
B.The Importance of Getting Rid of Air Pollution
C.Asian People Are Suffering from Serious Air Pollution
D.Air Pollution Reduces the Lifespan by More than One Year

Why would human beings waste a third of their lives sleeping when they could be doing more important things like looking after their families or working? Some scientists believe sleeping helps recharge the body, while others think it is important for strengthening newly-formed memories. Now, there is new evidence which suggests that the purpose of sleep may be to forget some of the millions of new things we learn each day.
The neurons (神经元) in the human brain consist of fibers called dendrites (树突). These grow as we learn new things and connect the brain's cells to each other at contact points called synapses (突触). The larger the dendrites become and the more cells they connect, the more information we store.
In 2003, Giulio Tononi and Chiara Cirelli, both biologists at the University of Wisconsin-Madison, suggested a new idea: The things our brains learn each day result in so many synapses that things start to get a little messy. Sleeping allows us to sort through the "noise" and dispense all the unnecessary information, leaving behind only the most important memories-
Recently, the university's research has provided direct evidence to support the theory. The experiment involved analyzing 6,920 synapses in the brain shavings from two groups of mice over a four — year period; one group had been allowed to sleep, while the other had been kept awake and entertained with toys. The researchers discovered that the brain shavings of the sleeping mice had nearly 20 percent fewer synapses than those that had been kept awake and entertained.
It was also evident during the study that the brain does not shave every synapse. 20% of neurons remained unchanged; these were most likely well-established memories. Therefore, although we may be sleeping to forget some of what we've learned, the brain "forgets" in a smart way.
Most researchers believe clearing our brains is not the only purpose of sleep. Resting our minds and bodies has also been found to help with other biological functions like strengthening our immunity. Though scientists may never agree on a single reason, they are all sure of one thing — a good night's rest is essential for our health. So try and spend at least a third of your day sleeping!
1.What will happen when we learn new things?
A.We tend to forget some key information.
B.We develop the ability to recharge the body.
C.The dendrites expand and connect brain's cells.
D.The neurons gather at what are called contact points.
2.Which of the following can replace the underlined word “dispense” in Paragraph 3?
A.Pick up. B.Get rid of.
C.Bring down. D.Pull out of.
3.What is the author's purpose of writing the text?
A.To prove a new theory.
B.To report a new discovery.
C.To show sleep good for memory.
D.To discuss how long one should sleep.
