NASA-s New Horizons probe(宇宙探测器)flew by Pluto(冥王星)this morning, sending back history's first up-close looks at the vast freezing-cold world. Closest approach came at 7:49 a.m. EDT. To celebrate, NASA gave out the latest photo of Pluto. It showed a reddish world with an amazing heart-shaped feature on its surface.
After today's close encounter, all the nine solar system's traditionally recognized planets have now been visited by a spaceship-a huge project begun in 1962 when NASA's Mariner 2 probe flew past Venus, a planet in the solar system. More than l,200 scientists, NASA guests and important persons, including 200 reporters, watched the flyby live at New Horizons' mission control center.
That close encounter has been a long time coming. The$723 million New Horizons mission launched in January 2006 but began taking shape in 1989. "New Horizons is'a capstone mission'," Glen Fountain, mission project manager told Space, com. "It is the first completion of the observations of our solar system. It-s giving us a new idea about how we human beings fit into the universe."
New Horizons "faced a crazy number of challenges," Stern, a driving force behind New Horizons said, "So many people stuck with this for so long. They got knocked down; they stood up. They got knocked down again; they stood up again.”
In a coincidence, today's close approach falls on the 50th anniversary of the first flyby of Mars, another planet, which was completed by NASA-s Mariner 4 spaceship.
There are no longer nine officially recognized planets, of course. The International Astronomical Union regarded Pluto as “a dwarf planet" in 2006 in a decision that remains controversial(有争议的)today.
1.Which statement is TRUE according to the passage?
A. Ideas still vary in the identity of Pluto.
B. Only scientists could watch the flyby live.
C. Mars is the first planet visited by a spaceship.
D. New Horizons mission aimed to observe the solar system.
2.Glen Fountain may probably agree that _____________________.
A. it is the most difficult to land on Pluto in the solar system
B. New Horizons mission is a long and troublesome project
C. their strong determination leads to the successful flyby
D. people are likely to find new ways to fit into space
3.Which is the best title for the passage?
A.A New Horizons Probe B. NASA's Huge Project
C. Pluto,a Controversial Planet D. A Close Approach to Pluto

As scientists probe(探究) the mysteries inside our heads, their discoveries are proving new insights into how we can all sharpen our mental machinery.
Your brain is fat
In fact, you brain is the fattiest organ in your body, consisting of a minimum of 60 percent fat. Fat carries, absorbs and stores vitamins in your bloodstream.1..
We can get smarter as we get older
Rawan Tarawneh, an assistant professor, points out that although some mental processes decline as we age, not all does.2., On the other hand, language functions tend to remain well preserved as we get older, peaking even into our early 70s.
3.
Comparing the brains of great thinkers, writers, and mathematicians hasn’t yielded conclusive evidence that the size of the brain has a connection to intelligence.
Intelligence might start with ignoring distractions
Intelligent people were better at detecting movements of small objects on a screen but worse at movements of large background objects. This may be because in nature, large movements such as the wind in the trees are irrelevant, but the harder-to-see animals is essential.4.
5.
For example, experiments have shown that people who were born blind use the visual parts of their brains for tasks other than seeing.

An exciting landing process of Chang'e-4 lunar probe (月球探测器 ) was seen through the monitor at Beijing Aerospace Control Center in Beijing, Jan. 3, 2019. It touched down on the far side of the moon at 10:26 a.m. Beijing Time, becoming the first spacecraft soft-landing on the moon's unknown side never visible from Earth.
China's Chang'e-4 probe has started the exploration on the far side of the moon thanks to the relay satellite that provides a communication link with ground control. The relay satellite, named Queqiao, meaning Magpie Bridge, after a Chinese legend (传说 ) , was launched on May 21, 2018, and became the first communication satellite operating in the halo orbit, nearly 500,000 km from the earth. It can also provide communication for probes from other countries. The relay satellite will also be used for scientific and technological experiments. The maximum distance between the satellite and the Chang'e-4 probe on the far side of the moon is 79,000 km. The satellite processes data from the probe and sends it to Earth.
The satellite can stay in its orbit for a long time due to its relatively low fuel consumption, as the earth's and moon's gravity balances its orbital moving. While in orbit, it can "see" both the earth and the far side of the moon.
The concept of using a relay satellite in the halo orbit was first put forward by U.S. space experts in the 1960s, but was realized by Chinese space engineers.
Researchers hope to use the cameras on the satellite to record asteroids (小行星 ) hitting the far side of the moon. To control the cost of the Chang'e-4 probe, the relay satellite was designed to be relatively small, weighing about 400 kg.
Researchers had just 30 months to develop the satellite, putting them under high pressure. To promote public interest in space exploration, the China National Space Administration invited people to write down their wishes for lunar and space exploration, and the relay satellite carries the names of tens of thousands of participants and their messages.
1.What do we learn from the second paragraph?
A. The relay satellite was launched on Jan. 3, 2019.
B. Chang'e-4 probe was the first communication satellite.
C. The relay satellite only explores the far side of the moon.
D. The relay satellite can handle data from Chang'e-4 probe.
2.Why was the size of the relay satellite relatively small?
A. To reduce the cost as much as possible.
B. To make it circle Moon for a longer time.
C. To avoid being crashed by other satellites.
D. To follow American space experts' advice.’
3.What made researchers suffer from great stress?
A. Few people interested in the exploration on the moon.
B. The relay satellite carrying too much equipment.
C. Their lacking enough time to develop the relay satellite.
D. People's never being optimistic about the relay satellite.
4.What is the main idea of the text?
A. China is a new space power after the USA.
B. Chang'e-4 probe lands on Moon's far side.
C. Chinese space engineers make much progress.
D. Space exploration is a dangerous challenge.

A new device is helping those who are blind to see. It does this in a new way by helping them experience the world around them. The technology is called Orion, manufactured by a company called Second Sight. 1. From being able to see absolutely nothing to suddenly seeing little flickers of light, the blind can move around alone, telling where a doorway is and where the sidewalk begins or ends.
2. One is a small device placed in the brain. There is also a video camera on sunglasses and a processing device carried in a person’s clothes. When the user points the camera, a signal goes to the processor and then back to the glasses. The glasses then communicate wirelessly with the device in the brain. The information causes a pattern to develop in the part of the brain called the visual cortex (皮质). 3. And it all happens in seconds.
Jason Esterhuizen is one of just two people in the U.S. testing this technology. He lost his eyesight after a car accident. He never thought he would be able to see light or movement again. But with the movement of a switch, his world suddenly grows brighter. 4.For example, it is easier and safer for him to cross the road because he can look down and just follow the white line that's painted on the road.
Researchers believe that one day this technology could benefit people who have lost their vision because of illnesses like glaucoma (青光眼) or diabetes. 5.
A.It may also help those with poor vision or who were born blind.
B.The new technology generally uses several parts.
C.He is amazed to have the functional vision again.
D.It is meant to help these people regain some independence.
E.He can do everyday activities that he once could not.
F.In this way, users detect movements and shapes of light.
G.It basically performs the functions of what the eye normally does.

Miss sending letters? Try Lettrs! This new service brings back the art of letter writing by marrying it to the Internet.
Lettrs, a new site, is attempting to bring back the old-fashioned idea of letter writing by providing a space that feels a little bit like a writing desk.
Of course, there’ll be purists who say that to truly enjoy letter writing you must do it on fancy letter paper and envelope in the mail is part of the fun. And if you’re into that sort of thing, go for it. But I can’t be the only one who is now so much faster at typing that writing by hand is painfully slow. Nor can I be the only one who likes to write on a whim (一时兴起) when I’m going to be on a crowded train or airplane, both of which are situations where writing on the computer is far easier.
The site tries, pretty seriously, to approximate(接近) what it’s like to have your very own writing desk and paper to choose from (which comes in various prints and colors) as well as corresponding(通信)types of prints and cursive writing (草写体) that come out on your screen as you write. There’s also a “desk drawer” for letters you’ve already sent, a “fridge” to post letters publicly, a “kitchen counter” for letters you have just received, and “shoebox” to store your letters in.
And if you need inspiration there are even old-style letters that are great examples of the kind of correspondence people used to send. Lettrs is such a great idea, because you get the best parts of communicating online (typing rather than writing, the speed, no lost mail, and it’s free! ) with the nice parts of a letter-the sense of sitting down to write, quietly, to one person in a meaningful way.
Who would you write to?
1.How does Lettrs work according to the text?
A. By providing real paper for letter writers.
B. By making room for people to write letters.
C. By supplying writing desks to letter writers.
D. By combining letter writing with the Internet.
2.It can be inferred from the text that the author_________.
A. is one of the purists
B. prefers writing to typing
C. always hopes to get paper letters
D. likes using Lettrs to write letters
3.A Lettrs user can find a newly received letter in or on a“_________”.
A. desk drawer B. fridge
C. kitchen counter D. shoebox
4.What is the main purpose of the author writing the text?
A. To advise readers to use Lettrs.
B. To tell readers how to write letters.
C. To persuade readers to write letters.
D. To show the advantage of the Internet.
5.What is the text mainly about?
A. An old art of letter writing.
B. A new service of letter writing.
C. The advantages of letter writing.
D. The development of letter writing.
