【题目】 Let us all raise a glass to AlphaGo and the advance of artificial intelligence. AlphaGo

DeepMind’s Go-playing AIjust defeated the best Go-playing humanLee Sedol. But as we drink to its success. we should also begin trying to understand what it means for the future.

The number of possible moves in a game of Go is so huge that. in order to win against a player like Lee. AlphaGo was designed to adopt a human—like style of gameplay by using a relatively recent development--deep learning. Deep learning uses large data sets“machine learning”algorithms (计算程序) and deep neural networks to teach the AI how to perform a particular set of tasks. Rather than programming complex Go rules and strategies into AlphaGoDeepMind designers taught AlphaGo to play the game by feeding it data based on typical Go moves. ThenAlphaGo played against itself, tirelessly learning from its own mistakes and improving its gameplay over time. The results speak for themselves.

Deep learning represents a shift in the relationship humans have with their technological creations. It results in AI that displays surprising and unpredictable behaviour. Commenting after his first lossLee described being shocked by an unconventional move he claimed no human would ever have made. Demis Hassabis. one of DeepMind's foundersechoed this comment“We're very pleased that AlphaGo played some quite surprising and beautiful moves. ”

Unpredictability and surprises are—or can be—a good thing. They can indicate that a system is working wellperhaps better than the humans that came before it. Such is the case with AlphaGo. Howeverunpredictability also indicates a loss of human control. That Hassabis is surprised at his creation's behaviour suggests a lack of control in the design. And though some loss of control might be fine in the context of a game such as Goit raises urgent questions elsewhere.

How much and what kind of control should we give up to AI machines? How should we design appropriate human control into AI that requires us to give up some of that very control? Is there some AI that we should just not develop if it means any loss of human control? How much of a say should corporationsgovernmentsexperts or citizens have in these matters? These important questions, and many others like themhave emerged in responsebut remain unanswered. They require humannot human - likesolutions.

So as we drink to the milestone in AI, let's also drink to the understanding that the time to answer deeply human questions about deep learning and AI is now.

1What contributes most to the unconventional move of AlphaGo in the game?

A. The capability of self-improvement.

B. The constant input of large data sets.

C. The installation of deep neutral networks.

B. We should call on the government to solve these problems for us.

【题目】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.

1What does the underlined word "immortal" in Paragraph 1 mean?

A. happy B. not moral

C. living forever D. sick

2What 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.

3Which 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.

4The 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
