D

Teachers say the digital age has had a good influence — and a not-so-good influence — on this generation of American teenagers.More than 2,000 teachers took an online survey.Three-quarters of the teachers said the Internet and digital search tools have had a “mostly positive” effect on their students’ research habits and skills.But 64 percent said the technologies “do more to distract (使……分心) students than to help them academically.” And 87 percent agreed that these technologies are creating an “easily distracted generation with short attention spans.”

The Pew Internet Project did the survey with the National Writing Project.Judy Buchanan is the vice director of the National Writing Project and a co-author of the report.Ms.Buchanan says digital research tools are helping students learn more and faster.“Teachers really favor these tools because they are ways to make some of the learning exciting and engaging.Young people favor these tools.The goal is to really help them become creators of meaningful content, and not just sort of consumers.”

But one problem the survey found is that many students lack digital literacy.They trust too much of the information they find on the Internet.Judy says these students haven’t developed the skills to determine the quality of online information.“It’s something that really has to be taught and paid attention to.Because in a world in which things happen quickly, you do need to step back, reflect and analyze the information you have.”

Another problem is blamed on something that might not seem like a problem at all: being able to quickly find information online.Teachers say the result is a reduction in the desire and ability of their students to work hard to find answers.They say students are overly dependent on search engines and do not make enough use of printed books or research libraries.

Many teachers are also concerned that the Internet makes it easy for students to copy work done by others instead of using their own abilities.

Mars( 火星) appears to be flowing with small streams of salty water, at least in the summer, scientists reported Monday."It suggests that.it would be possible for there to be life today on Mars," NASA's science mission chief, John Grunsfeld, said at a news conference on September 28, 2015.

The streams are about 12 to 15 feet wide and 300 feet or more long, scientists said."What we're dealing with is wet soil.thin layers of wet soil, not standing water," said Aifred  McEwen of the University of Arizona at Tueson ! the principal scientist for the Mars Reconnaissance Orbiter's high-resolution imaging experiment.

Because liquid water is essential to life, the findings could have major implications for the possibility of Martian life.The researchers said further exploration is needed to determine whether microscopic life exists on the planet.

The presence of liquid water could also make life easier for astronauts visiting or

living on Mars.Water could be used for drinking and for creating oxygen and rocket

fuel.NASA's goal is to send humans there in the 2030s.

The evidence of flowing water consists largely of dark, narrow streaks(条痕) on

the surface that tend to appear and grow during the warmest Martian months and fade

the rest of the year.

Mars is extremely cold even in summer, and the streaks are in places where the

temperature is as low as minus 10 degrees Fahrenheit.But salt can lower the freezing point of water and melt ice.

The source of the water is a mystery.Scientists noted it could be melting

ice.It could be an underground aquifer, which is rock or sand that can hold water.It is possibly water vapor from the thin Martian atmosphere, Or it may be a combination Michael Meyer, lead scientist for NASA's Mars exploration program, said the only definitive way for now to determine whether there's life on Mars is to collect rocks and soil for analysis on Earth - something a U.S.lander set for lift-off in 2020 will do.

1.What would be the best title for the text? '

A.Streams of Water Spotted on Mars

B.Astronauts will  Land on Mars

C.NASA's Mars Exploration Program

D.A Breakthrough in the Exploration of Mars

2.According to John Grunsfeld, there seems to be              on Mars.

A.salty water

C.rocket fuel

D.human beings

3.Scientists are uncertain about the               of the water on Mars.

A.state

We all know what a brain is.A doctor will tell you that the brain is the organ of the body in the head.It controls our body's functions, movements, emotions and thoughts.But a brain can mean so much more.

A brain can also simply be a smart person,  If a person is called brainy, she is smart and intelligent.If a family has many children but one of them is super smart, you could say, "She's the brains in the family." And if you are the brains behind something you are responsible for developing or organizing something.For example, Bill Gates is the

brains behind Microsoft

Brain trust is a group of experts who give advice.Word experts say the phrase

"brain trust" became popular when Franklin D.Roosevelt first ran for president in

1932,  Several professors gave him advice on social and political issues facing the U.S.

These professors were called his "brain trust."

These ways we use the word "brain" all make sense.But other ways we use the

word are not so easy to understand.For example, to understand the next brain

expression, you first need to know the word “drain." As a verb to drain means to,

remove something by letting it flow away.So a brain drain may sound like a disease

where the brain flows out the ears.But, brain drain is when a country's most educated  people leave their countries to live in another.The brains are, sort of, draining out of the country.

However, if people are responsible for a great idea, you could say they brainstormed it.Here, brainstorm is not an act of weather.It is a process of thinking creatively about a complex topic.For example, business leaders may use brainstorming to create new

products, and government leaders may brainstorm to solve problems.

If people are brainwashed, it does not mean their brains are nice and clean.To brainwash means to make someone accept new beliefs by using repeated pressure in a forceful or tricky way.Keep in mind that brainwash is never used in a positive way.

A.the brains behind Bai Du

C.the brain drain of Bai Du

D.the organ of Bai Du

2.Why did Roosevelt successfully win the election?

A.Because he was smart at giving advice.

B.Because word experts were popular.

D.Because he was the brains behind America.

3.Which of the following expression is always used in a negative way?

A.Brain trust

B.Brain  drain

A  I was very disappointed not to be able to go to the jazz concert last Friday.The advertisement in the paper said that you could buy tickets at the theatre box in Richland Hills any day between 10:00 and 4:00.Since I work from 9:00 to 5:30, the only time I could go to the theatre was during my 45-minute lunch break.

【2016模拟题】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

With his unique black mane (鬃毛)and impressive stature(身材), 13-year-old Cecil was a popular tourist attraction at the 3.6 million-square-acre Hwange National Park(万基国家公园) in Zimbabwe (津巴布韦).

Cecil was head of a pride of lions that includes 12 cubs(幼崽), but the well-known lion was shot and killed in early July by American dentist Walter J. Palmer.

Cecil’s death has already sparked an international outcry (强烈抗议) with many calling for an end to hunting endangered animals and for Palmer to be extradited(引渡) to Zimbabwe to stand trial.

Professor David Macdonald, the head of the Oxford University research program that monitored the daily movements of Cecil and dozens of other lions, is deeply saddened by Cecil’s death. Macdonald hopes the death can inspire the public to take an interest in lion conservation.

Macdonald says many of the lions tracked by the program have been shot  and killed. “The background to this story is that there is a crisis for lions throughout much of Africa.” He says.

African lion populations have fallen almost 60 percent over the past thirty decades, and as few as 32,000 of them remain in the wild, according to the International Fund for Animal Welfare(国际爱护动物基金会).

“And as troubling as it  is, the rarer these hunted animals become, the more hunter s are willing to pay to kill them,” said Jeff Flockedn, the fund’s North American regional director.

In addition to excessive hunting, lions throughout Africa also continue to face threats that include conflicts with local farmers, loss of habitat and risk of traffic and railway collisions(碰撞).

1. Internationally, people’s attitude towards Walter J. Palmer’s behavior is ________.

A. Understandable     B. Unpardonable

C. Unpredictable       D. Uncontrollable

2.According to the text, how many African lions lived in the wild thirty years ago?

A. 80,000         B. 48,000           C. 53,000          D. 60,000

3.African lions are facing the following threats except ________.

A. their conflicts with local farmers.

B. the loss of their habitats

C. people’s excessive hunting

D. the increase in the number of their natural enemies

4.The best title of the text might be ________.

A. The Death of Cecil-an African Lion

B. The Current state of All African Lions

C. The Threats Facing African Lions

D. The Appeal for an End to Hunting Endangered Animals
