While dog keepers realize their dogs can read their moods accurately, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.
For their study, biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.
Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That’s because the scientists believe humans show their emotions on their entire face.
After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.
They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.
The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner.
1.How did the scientists conduct the experiment?
A. By mixing the selected dogs together.
B. By leaving dogs to women who are either happy or angry.
C. By showing digital pictures of women’s happy or angry faces.
D. By rewarding only half of the dogs touching the screen.
2.Which of the following statements is TRUE about the dogs in the study?
A. The dogs were not all provided with the entire face.
B. The dogs couldn’t read strangers facial emotions.
C. According to their size, the dogs were given either upper or lower halves.
D. The dogs could make out small changes accompanying facial expressions.
3.The underlined word "trepidation" in Paragraph 5 probably means ________.
A. curiosity B. horror C. excitement D. doubt
4.How might the results change if the dogs with female owners are shown pictures of male faces?
A. They would be scared away at the sight of the pictures.
B. They found it easy to tell the emotions on the entire face.
C. They could only tell emotions on partial faces rather than on entire faces.
D. They found it hard to tell the moods on the faces of a different gender.

Cleaning your plate may not help feed hungry children today, but the timeworn advice of mothers everywhere may help reduce food waste from the farm to the fork, help the environment and make it easier to feed the world’s growing population.
Hard data still being collected, but experts in Chicago said about 30% to 50% of the food produced in the world goes uneaten. The average American throws away 33 pounds of food each month—about $40 worth, which means each person throws away almost 400 pounds of food. The US Department of Agriculture says that 23% of eggs and an even higher percentage of produce ends up in the trash.
“We forget we have all these fresh fruits and vegetables, and at the end of the week we have to throw them away”, said Esther Gove, a mother of three young children in South Berwick, Maine. “Now, I don’t buy as much fresh produce as I used to.”
But the effect of food waste arrives far beyond the kitchen. Agriculture is the world’s largest user of water, a big consumer of energy and major emitter of greenhouse gases during production. Experts say reducing waste is a simple way to cut stress on the environment and can ease pressure on farmers, who will be called on to feed an expected 9 billion people around the world in 2050, compared with nearly 7 billion today.
No matter how sustainable (可持续的) farming is, if the food’s not getting eaten, it’s not sustainable and it’s not a good use of our resources. In richer nations, fruit and vegetables end up in the trash because they aren’t pretty enough to meet companies’ standards, have gone bad in a home refrigerator or aren’t eaten at a restaurant. In developing countries, much food spoils before it gets to market due to poor roads and lack of refrigeration. High food prices are another reason, since some people can’t afford the food that’s produced.
1.From the first paragraph, we know that cleaning your plate ________.
A. is you mother’s best advice for you
B. can solve certain problems for the world
C. can help feed hungry children all over the world
D. helps meet the growing population’s needs
2.The underlined word “emitter” in Paragraph 4 means ________.
A. user B. finder C. protector D. producer
3.What is a sustainable and convenient way for a customer in a restaurant?
A. Ordering enough and packing the leftovers.
B. Ordering more than he or she can eat.
C. Ordering less and feeling hungry after leaving.
D. Ordering more and leaving the untouched alone.
4.Which of the following topics will follow the text?
A. More examples of food waste. B. Ways to reduce food waste.
C. Experts’ idea on the environment. D. Advice for food with high prices.

You use her as a shoulder to cry on. She texts you back with casual jokes. But she, Xiaoice, is only a virtual chatbot.
Xiaoice, Microsoft’s latest artificial intelligence robot, was briefly released in 2014, and returned to WeChat in 2015, where she became a big hit. Millions of young Chinese now exchange messages with her daily, The New York Times reported. On WeChat, Xiaoice is an official account. After following it, users can start text-based conversations with Xiaoice.
“Her incredible learning ability was why people loved to talk with Xiaoice,” Liu Jinchang, a researcher at High-tech Research and Development Center under the Ministry of Science and Technology, told China Daily. Apart from her ability to identify photos and send emojis (表情符号) in conversations, Xiaoice gains 45 percent of her knowledge from interacting with users, China Daily reported.
Chatbot programs first appeared in the mid-1960s in the US. Driven by top tech companies, they are becoming smarter and more common. For instance, IBM’s latest artificial intelligence program served as an academic consultant at Australia’s Deakin University, answering students’ questions about course schedules and financial aid. Apple’s Siri and Amazon’s Alexa have been used as voice assistants who can read news, play music and even make jokes for their users.
These programs are expected to move beyond smartphones, into televisions, cars and living rooms. The New York Times pointed out. However, it may take decades before scientists develop a “Samantha”, the advanced chatbot seen in the fiction film Her. In the film, Samantha sparks a romantic relationship with her user played by US actor Joaquin Phoenix. Many viewers were enthusiastic about this fantasy of virtual soul mates.
1.What does the underlined part in Paragraph Two mean?
A. She became a best seller. B. She became very powerful.
C. She became a money maker. D. She became very popular.
2.Which of the following can Xiaoice do?
A. Do housework. B. Spread messages.
C. Identify various photos. D. Read news to its users.
3.Which company’s chatbot program can act as an academic consultant?
A. Microsoft. B. IBM. C. Apple. D. Amazon.
4.What can be learned from the last paragraph?
A. Chatbots mainly run on smartphones now.
B. It’ll take decades to apply chatbots to cars.
C. Samantha is played by a US actor in the film.
D. The film Her doesn’t interest many audience.

When I was a little girl, my family were very poor. My parents were workers but couldn't afford to buy toys for me. As a result, my dolls looked a lot differently from that bought from toy stores. My dolls were home-made. The first doll I owned was made of a glass Coca-Cola bottle. I was so excited to make a doll by my own. Soon I became a collector of empty Coca-Cola bottles although I saw each bottle as possible baby doll at that time. People who worked in the store sell Coca-Cola could see me pick up empty bottles almost every day. Those home-made toys had brought me a lot of happy.

In the past, teachers always kept on to explaining the points in class. Our students just listened and take notes. But now we often discuss and try to solve the problems raising by the teachers or ourselves. After class, we enjoy different kind of activities instead of doing endless homework. For example, we can read that we are interested. We can go to the library and surf the Internet for variously kinds of information. In my opinion, exploring study does not only help us learn much, but also make us to enjoy study and become masters of study.

I love camping. It’s my favorite way to spent the summer vacation. Last year, my family and I went camping in the countryside. It was one of the most excited experiences I had never had. We slept in a tent and went on a long walk every day. We cook over a fire and the food always tasted wonderfully. For a whole week, I saw lovely mountain views or breathed fresh air. At night, I heard the gentle wind blowing in the tree, and I felt so peaceful. It doesn’t cost many to camp, and what I believe it’s the best way to get close nature and enjoy its beauty.
