With the growing popularity of the Internet, more and more children are addicted to play online games day and night. It does harm not only to their health, especial their eyes, but also to their studies.
Comparing with online games, many traditional games, like hide-and-seek, benefits kids mentally and physically. They were ever popular with several generations, which not only learned anything valuable but also enjoyed playing the games. Therefore, the games are dying away now.
Personally, I think teachers and parents should take measure to limit their children’s Internet time. Let children to know the harm of online games and the benefits of traditional games. Help children judge healthy and unhealthy games. What’s more, we should often organize events for children in which traditional games played.

Good news for giant panda lovers: The cute and cuddly creature has just been brought back from the brink of extinction.
The International Union for Conservation of Nature (IUCN) downgraded the species from “endangered” to “vulnerable” as the union released its updated Red List on Sept 4 at Hawaii.
The downgrade came after IUCN data suggested that there were 1,864 giant pandas in the wild in China in 2014 — their population has grown by 17 percent in the decade leading up to 2014.
Chinese conservation efforts, including forest protection and reforestation, are considered to be the driving force behind the animal’s resurgence.
“It’s all about restoring the habitats,” Craig Hilton-Taylor, head of the IUCN Red List, told the BBC.
The number of panda reserves in China has also jumped to 67, from 13 in 1992. Nearly two-thirds of all wild pandas live in these reserves, according to the World Wildlife Fund.
“Just by restoring the panda’s habitat, that’s given them back their space and made food available to them,” Hilton-Taylor said.
A loss of habitats, on the contrary, was what caused the number of pandas to drop to just over 1,200 in the 1980s, Hilton-Taylor added.
Apart from giant pandas, the Tibetan Antelope has also moved from “endangered” to “near threatened”. According to a statement from IUCN, the animal’s numbers dwindled severely — dropping from around 1 million to an estimated 65,000-72,500 in the 1980s and early 1990s — due to commercial poaching. Rigorous(嚴(yán)格的) protection has since been enforced to protect the beasts and the population is now likely to be between 100,000 and 150,000.
Despite the improved statuses, wild animals like the giant panda and the Tibetan Antelope still face great challenges. The IUCN warned, for example, that ongoing threats from climate change could eliminate more than 35 percent of the panda’s bamboo habitat in the next 80 years, which would reverse the species recent gains.
1.What does the underlined word in pagagraph 1 mean?
A. dangerous and threatened.B. safe and sound.
C. weak and easily hurt.D. normal and common.
2.Which of the following can account for pandas’ living improvement?
A. Better climate.B. More built reserves.
C. Well restored habitats.D. Aroused public awareness.
3.The passage is written in order to ________.
A. convinceB. informC. argueD advocate
4.What does the last paragraph imply?
A. The climate will influence the threatened species.
B. We humans still have a long way to go to protect the endangered species.
C. Pandas will go extinct for lack of abundant food.
D. Habitats for giant pandas will decrease sharply.

Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.
Why is poker(撲克) so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players’ cards are hidden, making it an “information incomplete” game. Players have to guess opponents’ hands from their actions—tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.
Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold’s Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神經(jīng)的) networks and reinforcement learning(強(qiáng)化學(xué)習(xí)).
Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.
Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”
After two hours of quite defensive play, from the computer at least, we called it a draw.
1.Why can’t the computer beat humans at the poker game?
A. Because humans are cleverer than the computer.
B. Because humans practice playing the poker game every day.
C. Because the computer can’t learn the regular rules of the poker game.
D. Because the computer can’t know the other players’ cards completely.
2.What does the underlined word “vanquishes” in Paragraph 3 mean?
A. Leaves.B. Defeats.C. Cheats.D. Serves.
3.What do we know about the reinforcement learning of AI?
A. It solves problems correctly every time.
B. It is the same as the learning of humans.
C. It learns from the mistakes appearing in a task.
D. It is more developed than the studying ways of humans.
4.What can be inferred from the text?
A. The new procedure of AI has some features of humans.
B. Computers are stronger than humans in every aspect.
C. Humans will beat computers at playing poker forever.
D. Scientists feel unhappy about the result of the poker game.

Public bookshelves are appearing across Germany on street corners,city squares and in suburban supermarkets. In these free-for-all libraries,people can grab whatever they want to read,and leave behind anything they want for others. There’s no need to register,no due date,and you can take or give as many as you want. “This project is aimed at everyone who likes to read .It is open for everybody,” Michael Aubermann,one of the organizers of the free book exchange said.
The western city’ s latest public shelf was put up next to Bayenturm. It is the fourth free shelf that Aubermann’ s group,the Cologne Citizen’s Foundation,has placed outside.“We set up our other outdoor shelves last year and it’s been working really well,” said Aubermann. The public bookshelves,which are usually financed by donations and cared for by local volunteer groups,have appeared independently of each other in many cities,suburbs and villages. Each shelf holds around 200 books and it takes about six weeks for a complete turnover,with all the old titles replaced by new ones.
Even commercial book stores and online book sellers seem to support the idea of free book exchanges.“We see this project rather as a sales promotion than as competition,”said Elmar Muether.“If books are present everywhere,it helps our business,too.”
So far,the Cologne book group has had few problems with damage or other problems. Aubermann said,“Propaganda (宣傳) is the only kind of literature we do not allow here.”
At another bookshelf in the Bayenthal neighborhood,the lower shelves are reserved for children’s literature only.“It is important that we make it easy for everyone to participate in this ‘reading culture on the street’—from old readers to kids to immigrants,”Aubermann said.
While most of the shelves have so far been put up in upscale neighborhoods,Aubermann and the 20 volunteers who help look after the project are planning to put up future shelves in poor neighborhoods,where citizens often don’t have as much access to literature.
1.Which of the following is TRUE about the public bookshelves?
A. People can take the books and leave their books at will.
B. People can’ t borrow books unless they donate books.
C. People can borrow whatever they like after registering.
D. People have to return the books according to the required time.
2.According to Aubermann,the public bookshelves ________.
A. are financed by local volunteers
B. have been going well since their birth
C. were managed by the local government
D. will hold more books and take a shorter turnover
3.The underlined phrase “upscale neighborhoods” refers to ________.
A. communities that have many people
B. communities that have many tall buildings
C. communities that are free to live in
D. communities that are of high grade
4.Which might be the best title for the passage?
A. Public Reading Becomes Popular Worldwide
B. New Trends of Bookshelves in Germany
C. Public Bookshelves Spread Across Germany
D. Reading Culture on the Street in Europe

JOHANNESBURG—They say cats have nine lives. Now a Chinese toad(蟾蜍) has joined that club of clever survivors.
South Africans are shocked at the endurance of a toad that got trapped in a cargo shipment from China to Cape Town, after jumping into a porcelain candlestick(燭臺) that was made there. South African officials reportedly planned to put down the creature, fearing it would cause harm as an invasive species if it were let go in the wild.
But the toad got a last-minute pardon. Mango Airlines, a South African airline, transported the toad on Friday to Johannesburg for delivery to an animal shelter, after officials decided to find a way to let the toad live. The two-hour flight was a breeze compared to the trip from China, a long way of many weeks and thousands of kilometers across the Indian Ocean.
Airline spokesman Hein Kaiser said the toad got “first-class treatment”, sitting in a transparent plastic container with escort Brett Glasby, an animal welfare inspector. There was even a ceremony, in which the toad’s boarding pass was handed to Glasby.
“He was the star of the show on the flight,” Kaiser said of the amphibious(兩棲的) passenger. “I think every passenger stopped to have a look.”
On landing in Johannesburg, the toad was brought out of its container for a celebrity-style photo shoot. Observers said the brown toad seemed like a cool customer. It belongs to the Asian Toad species, which breeds during the monsoon(季風(fēng)) season. It is believed to have survived the trip from China by hardening its skin to prevent it from drying out, and also by slowing its breathing and heart rate—methods that help the species survive in times of drought.
“We’ve had snakes in imported timber and scorpions(蝎子) in fruit. We were called because the toad was right inside the candlestick, and we had to break it to get it out” Glasby, the inspector, told The Star, a South African newspaper.
1.What is the passage mainly about?
A. Asian toads can’t get used to the life in South Africa.
B. South Africa ignores the protection of animals.
C. An Asian toad gets a new home in South Africa.
D. Workers shipped a toad to South Africa on purpose.
2.If the toad is released into the wild, ________.
A. it will make the locals feel shocked
B. it will lose its life in the wild
C. it might flee into another country
D. it might harm the native species
3.The toad was able to arrive in South Africa alive ________.
A. because it formed hard skin to protect itself
B. because it escaped all attacks and hunts
C. because it used to stop its breath in winter
D. because it was lucky to be given a chance
4.It can be inferred from the passage that ________.
A. a candlestick is the best place for a toad
B. droughts make toads live longer
C. sometimes animals are transported accidentally
D. no one has seen such a big toad in Africa

A short guide to surviving a post-election Thanksgiving
Thanksgiving in the US is a celebration of the blessings of the previous year. This time it included one of the most divisive presidential campaigns. Even now it is over, the possibility of argument has not disappeared. Here we have some tips for you to survive this Thanksgiving.
●Cover up any signal of union
It might be fine to have your Hillary bumper sticker in New York, but it isn't going to go down well in Wyoming, where 70% voted Trump. Similarly, your "I love Trump" T-shirt will probably not be popular in California, where 62% voted Hillary.1..
●Practice your facial expression beforehand
They say a picture tells 1,000 words. Your face is the same. 2.You need to invest some energy in making sure your true feelings are completely buried. Ten minutes in front of the mirror should be enough to perfect your neutral face. 3.Well, we suggest closing them. Easy.
●Have a list of neutral topics for the dinner table
The weather is A favorite subject of the British. It is inoffensive, bland and can provide a good half-hour's chat, if done well. Everyone has an opinion on whether or not it is colder/hotter/wetter/windier than last year/10 years ago/when they were little. You can involve the whole family.4.With Clinton and Trump supporters largely split on whether climate change exists, it could inadvertently lead to politics. So it's maybe trickier for Americans than the weather-worn Brits. 5.After all, the rivalry between your American football team of choice and your cousin's may have a long and vitriolic history, but it is likely to be less poisonous than the current differences in your politics.
A. Sports may not be a neutral subject.
B. Biting your lip is simply not enough this holiday season.
C. There are hundreds of outstanding topics for Thanksgiving.
D. There is one slight downfall to this particular favorite.
E. Are you one of those people whose eyes always tell the truth?
F. So we advise leaving the T-shirt at home, and covering up the stickers.
G. It would be fine, if people of different opinions would not spend Thanksgiving together.
