High school students have defeated1.artificial intelligence device designed to pass the national college entrance exam, in Chengdu City, Sichuan Province.
Forty-three students from liberal arts classes at Chengdu Shishitianfu High School joined the two-hour contest 2.(finish) a math test in the standard national entrance exam against the robot, the brainchild of four years' research by Zhun Xing Yun Xue Technology Co.Ltd.
Students scored 106 points3.average, outperforming the computer program that had 93 points. She Yujia, a student in the contest, said she felt like4.(fight) the program on behalf of humans, especially after Google's AlphaGo 5.(beat) professional Go player Lee Sedol of South Korea last year.
Researchers who developed the AI test taker, 6.is also part of a project by the Ministry of Science and Technology, said the failure was due to a poor understanding of concepts in some math problems.
Lin Hui, CEO of the developing company, said more efforts 7.(make) to fix bugs and improve performance of the program in the near future, with a focus on math 8.(apply).
Chinese students are usually separated into science and liberal arts classes at high school, a practice that allows them to stay 9.(compete) in the college entrance exam by choosing 10.(prefer) subjects. Math tests for liberal arts students are usually easier than those given to science students.
The Belief of a Teacher

I don't accept excuses about kids not learning. That's________the kids with problems are not going to________start teaching themselves. We have to help them by finding out what________them and exploiting(利用) it shamelessly.

Common public speaking problems
The use of "I feel", "I think" and "maybe"
In the question-and-answer session of the speaking competition, many contestants began their answers with uncertain expressions like "I feel", "I guess", "I hear", "maybe" and "perhaps".
These words show that the person is only speaking from his or her point of view.1.
Work on keeping your answers brief and to the point, 2.. Instead of the empty-sounding "I guess", using facts, together with a clear conclusion based on those facts, is far more likely to be popular with an audience.
Using only one speaking style
Don't stick to the same tone.3.
For example, when they spoke about their dreams, some sounded romantic. Others used humor. Very few used several different styles together. Try mixing more than one style, rather than just sticking with the same one.
Irresponsible answers
Public speaking is different from personal conversations. You're responsible for your words. 4.So you should think twice before you talk. Don't be like the student who, when asked about his opinion on book piracy（盗版）, started by saying he supported it.
Talking around the topic rather than directly answering it
You should focus on one point and give a clear solution. The key is to work out what question is being asked. Is it asking you to discuss a certain topic or to present your own point of view?
Use one or two arguments together and give a strong conclusion.5.
A. It can be boring. Try to mix it up.
B. Even though you want to answer quickly, you don't want to sound foolish.
C. Also work on delivering them with calmness and confidence.
D. Deliberate gestures and affected（做作的）expressions of feelings are improper in a successful speech.
E. Remember that judges are not judging you on whether they agree, but on your ability to say what you think clearly.
F. This lacks the support of facts and seems not to be reliable for the judges and audience.
G. Confidence is extremely important in public speaking as it lets a speaker sound more convincing.
In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse（诅咒）;in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets（药丸）that contained mercury（水银）, believing that it would make them immortal, but they died afterward.
Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?
An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.
The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars（毛毛虫）, frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.
"Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."
A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.
The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances（物质）that we regularly ingest（摄入）-chili, coffee and chocolate-owe their special flavors or stimulating（提神的）effects to chemicals that plants make to poison insects.
1.What does the underlined word "immortal" in Paragraph 1 mean?
A. happy B. not moral
C. living forever D. sick
2.What is the main purpose of the exhibition The Power of Poison?
A. To give people more in-depth knowledge about poison.
B. To teach people how to handle poisonous animals.
C. To inform people about which animals are the most poisonous.
D. To show how poison has been used for medical treatment.
3.Which of the following statements about the Golden poison frog is TRUE according to the article?
A. Its skin can cut off the signaling power of your nerves.
B. It's about the size of a coin.
C. It's the most poisonous animal on display.
D. You can only see it in a rainforest setting of the museum.
4.The stimulating effects of coffee come from ________.
A. natural poison made by the plant
B. the substances that we regularly ingest
C. chemicals produced by poisonous insects
D. its special flavor

Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least conventional and generally agreed.
Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society-than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.
Furthermore, social change is easier if it is gradual. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and white people.
