An experimental cleanup device called RemoveDEBRIS has successfully cast a net around a dummy (仿真的) satellite, imitating a technique that could one day collect spaceborne garbage.

The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space.

Millions of pieces of junk are turning around in orbit, the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause critical damage.

Various companies have plans to send thousands of new satellites into low-Earth orbit, already the most crowded area.

The RemoveDEBRIS experiment is run by a company and researchers led by the U. K.’s Surrey Space Center and includes Airbus, Airbus-owned Surrey Satellite Technology Ltd. and France’s ArianeGroup.

Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10 meters long.

The RemoveDEBRIS satellite will conduct a few more experiments in the coming months, including testing navigation features that could help guide the satellite to a specific piece of debris.

Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, said the success of this week’s experiment was exciting, but he cautioned against “over- publicizing” it.

There are still enormous barriers to clear before operational cleanup tasks are underway, he said, and the most discouraging is figuring out how to fund such projects.

Aglietti, the Surrey professor who helped lead the RemoveDEBRIS project, said “The challenge will lie in persuading the relevant authorities to sponsor these tasks.” Aglietti said he hopes RemoveDEBRIS will conduct a few cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.

1.What is the use of the RemoveDEBRIS satellite?

A. Demonstrating space technology.

B. Imitating a developing technique.

C. Collecting wastes existing in space.

D. Symbolizing great progress in space.

2.How does the RemoveDEBRlS satellite work?

A. By throwing a net to take the junk from orbit.

B. By fastening it to the main satellite tightly.

C. By dragging satellites up to 10 meters long.

D. By targeting large pieces of junk carefully.

3.What does the underlined word “sponsor” in the last paragraph probably mean?

A. Accomplish. B. Support. C. Oppose. D. Provide.

4.What’s the best title for the text?

A. The RemoveDEBRIS Project Is Perfect

B. How RemoveDEBRIS Is Invented in the Lab

C. Why the RemoveDEBRIS Satellite Is Invented

D. Satellite Collects Space Junk for the First Time

Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子)，but it’s not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

On board the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there's a face you see frequently, it’ll try to get nice photos of those faces,” said Juston Payne, the device’s product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot — like when a child’s hand is over the lens, or if it is tossed in a dark purse.

The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

“This product is only possible because of the way that silicon has advanced” Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we’re likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

1.What is the most outstanding feature of Clips?

A. It allows of hands-free photography.　　 B. It enables easy internet access.

C. It is equipped with tough glass.　　 D. It can be worn on your clothing.

2.What does the underlined word “candid”, in Paragraph 2 mean?

A. touching.　　 B. brief　　 C. unforgettable.　　 D. embarrassing.

3.What makes Clips a reality according to Juston Payne?

A. The advance in technology.　　 B. The popularity of the Internet.

C. The rise of the smartphone industry.　　 D. The reduction in the price of lens.

4.What is the best title for the text?

A. Artificial Intelligence in Everyday Life.　　 B. New Gadgets in the Age of Apps.

C. A New Digital Camera from Google.　　 D. An Alternative Way to Photograph.

A device called a TreeTalker is providing information about trees to people who oversee forests and woodlands. The device aims to measure the growth and general health of trees.

Scientists say forests are important because they absorb, or take in, carbon dioxide, one of the gases released by burning oil and other fossil fuels. It is a heat-trapping gas and has been linked to a general warming in the Earth's atmosphere.

The world is at a historic period for climate change because the scientific world is on guard. Many scientists say “Be careful, the ecosystem of the forests is not able anymore, as it was before, to absorb all this carbon dioxide.” Rising temperatures are placing forests under increased stress. Harmful insects and diseases are becoming more of a threat to trees. This is bad for the environment.

The TreeTalker devices serve as an early warning system for people overseeing forests. TreeTalker turns eco-physiological signals, such as growth, absorption of carbon dioxide, liquid flow from roots to leaves, into scientific information. This can help show if a tree is under attack from insects or other organisms. The TreeTalker sends its information to forest managers.

The TreeTalker device transmits data via radio and it can transmit data actually a very long distance, up to one kilometer. The information lets forestry officials take action immediately to control threats. The TreeTalker is able to measure the width of the bottom of a tree. Timber industry workers can use this information to know how much wood they are growing compared to how much they are harvesting. Another goal is to give scientists the information they need to understand how climate affects forests and the part trees play in a healthy environment.

About 300 TreeTalker devices are being tested in Italy and other countries, such as China and Russia. Another 1,700 devices are expected to be tested worldwide this year.

1.What was the TreeTalker device used for?

A.Providing information of forests change.

B.Absorbing carbon dioxide.

C.Controlling threats from nature.

D.Helping the growth and health of trees.

2.Which of the following threats to forests is the most severe?

A.Harmful insects and diseases. B.Forest managers.

C.Carbon dioxide. D.Timber industry workers.

3.What does the underlined word “This” in paragraph 4 refer to?

A.The information of an early warning system.

B.The information on the absorption of carbon dioxide.

C.The information of eco-physiological signals.

D.The information to the forest managers.

4.What’s the author’s attitude towards the TreeTalker device?

A.Promising. B.Alarming.

C.Doubting. D.Understanding.

A branch of psychology called neurolinguistic programming has made an interesting and useful discovery :You can change the way you imagine or remember things without changing what you imagine, and it will change your feelings．For example, if a visual memory makes you sad whenever you think about it, you can make that mental picture smaller and dimmer, and when you do, the memory won’t make you as sad．Since you haven’t changed the content of the memory, you haven’t lost any information．You have simply made it less painful．

When you visually remember a pleasant memory, you can made the picture more colorful and the money will give you even more intense good feelings．You can make your pictures of the future brighter, wider , deeper, or you can bring the images closer．Changes like these will make you feel different--- even when you leave the content of the picture the same．

These are general guidelies （ 指导方针 ）．You’ll need to experiment for yourself to find out what will work for a particular image．For a few people, making an exciting picture brighter makes the feelings less intense．And for some kinds of pictures, increasing the brightness would cause the feelings to become less intense --- for example, a romantic memory．

What is true for visual images also applies to the way you talk to yourself．

For example, if you have trouble motivating yourself , try changing the tone of voice you use when you spread to yourself．Some people order themselves about ．The voice they use to talk to themselves is harsh and commanding．Listening to yourself being bossy can have the same effect as listening to someone else being bossy: It can make you want to rebel．Change your tone to friendly or seductive, and you might feel more motivated ．When you tell yourself, “I can do it,” fill your internal voice with enthusiasm and back it up with inspiring music．The possibilities are in fact endless．

The important thing to understand is that they way you code your inner world has an impact , and you have quite a bit of control over that coding．You can change it deliberately．When you do , it will change your feelings, which change your actions, which will change the world around you．．

1．Which is the best title of the passage?

A．You Can Change the World Around You

B．Be Merry

C．You Can Change People’s Attitude towards You

D．Talk to Yourself in a Friendly Way

2．The underlined word  “deliberately “ can be replaced by ___

A．by change              B．on purpose             C．difficultly      D．wiser

3．We can infer that if we make a sad mental picture bigger and brighter, we can become _____

A．happier        B．sadder                C．calmer              D．wiser．

4．What does the underlined sentence “Some people order themselves around” suggest?

A．Some people order a lot of food．

B．Some people order others to follow their instructions

C．Some people are very hard on themselves

D．Some people are very strict with themselves．

Dog owners now have a little help understanding their furry friends . A new device called Bow-Lingual “translates” dog barks into English , Korea or Japanese.

Bow-Lingual’s Japanese inventors spent much time and money analyzing dog barks . They found that dog noises can be broken down into six different emotions : happiness , sadness , frustration , anger , assertion and desire .

Part of the Bow-Lingual device hangs on the dog’s collar . The other part is a handle-held unit for the owner . When the dogs barks , the unit displays translated phrases .

Some people have scoffed at Bow-Lingual. “Who would pay US$ 120 to read a dog’s mind?” they ask .

But those who have purchased Bow-Lingual praise the device . Pet owner Keiko Egawa , of Japan , says it helps her empathize with her dog , Harry . “Before we go to the park , he always says he wants to play,” says Egawa , “and after a walk , he always says he is hungry.”

Bow –Lingual is not yet available in Chinese . So you’d better keep studying Studio Classroom , or soon your dog may know more English than you do !

1.This passage is mainly talking about ________ .

2.Which of the following sentences is TRUE according to the passage ?

3.What does “scoffed at” mean in the 3rd paragraph ?

4.How do you understand the sentence “Bow-Lingual is not yet available in Chinese” in the last paragraph ?

5.The writer of this passage is most likely to be ________ .
