【題目】In 2017, AlphaGo defeated Chinese player Ke Jie to become the world’s No 1, ending thousands of years of human dominance（控制）in the game. AlphaGo is an artificial intelligence（AI）Go-playing program.【1】

Artificial intelligence（AI）is usually defined as the science of marking computers do things that require intelligence when done by humans.【2】These include learning, reasoning, problem-solving, perception, and language-understanding.

【3】In fact we are increasingly depending. upon computer-based artificial intelligence. As Charlie Qrtiz said, head of AL at the Massachusetts-based software company Nuance Communication, “It has opened a window for us.”Smartphones, self-driving cars, intelligent robots，etc. are constantly coming into our life. According to a recent survey, half of the world’s AI experts believe human level machine intelligence will be achieved by 2040. This will open up huge possibilities for the enrichment of mankind, from tackling climate change and treating disease to labour- saving devices.

【4】Physicist Stephen Hawking last year warned that unless we take care, board games might be the least of it. “The development of full artificial intelligence could mean the end of the human race.”【5】They believe AlphaGo’s victory is a reminder of how fast the world is overcoming the obstacles in the way of AI, and its distribution in the world about us. Although there may yet be no evidence that computers will ever shake off their human masters, we should still treat these development with the humility and caution they deserve.

A. Other scientists have also expressed the concern.

B. Artificial intelligence has both advantages and disadvantages.

C. Defeating a human Go master is not the only thing AI can do.

D. Artificial intelligence will bring us disasters instead of benefits.

E. It was designed by an American Artificial intelligence company.

F. Not all experts hold the optimistic attitudes to the development of AI.

G. Research in AI has so far focused on some special fields of intelligence.

【答案】

【1】E

【2】G

【3】C

【4】F

【5】A

【解析】文章主要講述了人工智能，以及人們對(duì)于人工智能的不同態(tài)度。

【1】根據(jù)前句內(nèi)容AlphaGo is an artificial intelligence（AI）Go-playing program. 可知，此處是對(duì)阿爾法狗的介紹，所以E合適，意為它是被美國(guó)的人工智能公司設(shè)計(jì)的。

【2】根據(jù)后句的內(nèi)容These include learning, reasoning, problem-solving, perception, and language-understanding.可知，主要介紹了人工智能研究涉及的領(lǐng)域，所以前句是對(duì)對(duì)研究的評(píng)價(jià)，引出后句的研究領(lǐng)域。所以G正確。這些領(lǐng)域包括學(xué)習(xí)，推理，問(wèn)題解決，感知以及語(yǔ)言理解等。

【3】根據(jù)后句內(nèi)容In fact we are increasingly depending. upon computer-based artificial intelligence.。。。Smartphones, self-driving cars, intelligent robots，etc. are constantly coming into our life.可知人工智能現(xiàn)在已經(jīng)被應(yīng)用于很多領(lǐng)域，所以此處表示在圍棋比賽中戰(zhàn)勝人類不是人工智能唯一的表現(xiàn)。所以C正確。

【4】根據(jù)后文內(nèi)容Physicist Stephen Hawking last year warned that unless we take care, board games might be the least of it. “The development of full artificial intelligence could mean the end of the human race.可知人們對(duì)于人工智能的觀點(diǎn)有些是消極的。所以F正確。

【5】根據(jù)后文的They believe AlphaGo’s victory is a reminder of how fast the world is overcoming the obstacles in the way of AI, and its distribution in the world about us.可知，此處仍表達(dá)一部分人的觀點(diǎn) ，所以選A，表示其他的科學(xué)家們也表達(dá)了關(guān)注。

To me, inspirations mean to put my thoughts, heart, and creations into my jewelry. Sometimes I become so inspired with what I'm working on that I can finish one or more sets in less than an hour. Because of that feeling, I have named my jewelry collection “Inspirations”.
I am a 17-year-old student with sickle-cell anemia. With this, I am in and out of the hospital a lot. So I started making jewelry a year ago when I was in the hospital. I really needed something to do, so I was introduced to jewelry making by a child life expert.
One day while lying in my hospital bed, I decided to get up and go to the patient's playroom ,and look through the craft designs. That was when I became inspired to design my jewelry collection, and named it “Inspirations”.

When I need a break or just to be free I turn to my craft activities. This is a way to ease my mind and it always helps me to especially get through those stressful times.
I am getting very excited about graduating next year and preparing myself for college. Who knows my collection of “Inspirations” would take me to the places I always dreamed of? I may see celebrities I admire and even sell them some of my beautiful “Inspirations”. If they wear my “Inspirations”, it will be well known and in great demand. What a great way to make some extra money for college! I never thought being sick would bring me “Inspirations”.

【題目】A 16-year survey on the arctic Norwegian island of Svalbard found the reindeer（馴鹿）there have declined in weight by an alarming 12 percent. The reduction in average body-mass is being blamed on global warming.

In research presented lately at a meeting of the British Ecological Society in Liverpool, scientists will explain how rising temperatures are making female reindeer difficult to obtain nutrients during important periods of being pregnant.

Snow in Svalbard typically covers the ground for eight months of the year, which, combined with low temperatures, limits grass growth to June and July. But as summer temperatures have increased by around 1.5℃, grasslands have become more productive, allowing female reindeer to gain more weight by the autumn and therefore to conceive（孕育）more calves.

However, warmer winters have brought with them greater rainfall which freezes when is settles on the snow, therefore locking out the reindeer from the life-supporting food below. As a result, female reindeer are becoming starved, causing them to give birth to much lighter young. The average mass of an adult reindeer in 1998, when the survey began, was 55kg, but by 2016 IT had dropped to 48kg.

Professor Steve Albon, an ecologist at the James Hatton Institute in Aberdeen , said that, because the mammals have a relatively high surface-area-to-volume ratio（表面積與體積比）, they are no particularly energy efficient.

Reindeer can often access the inadequate food sources beneath the snow by clearing IT away with their antlers（鹿角）, but they cannot break through the hard ice. Without access to the food in winter, calves are being born far lighter than they should be. Numbers of reindeer have also increased rapidly in the past 20 years, meaning that those which are born are facing greater competition for food. “The implication（含義）are that there may well be more smaller reindeer in the Arctic in the coming decades, but possibly at the risk of catastrophic die-offs because of increased ice on the ground,”said Professor Albon Despite the gloomy findings, reindeer appear to be suffering less from the impact of climate change than some other arctic species.

【1】Which of the following may be the most important reason for the smaller reindeer?

A. Heavy snow.

B. Greater rainfall.

C. Hard ice.

D. Global warming.

【2】According to the passage, rising temperatures will not lead to_________.

A. grass growing more rapidly in summer

B. more rainfall in the arctic area in winter

C. female reindeer’s gaining more weight in winter

D. female reindeer’s suffering from hunger in winter

【3】What does the underlined word“gloomy”in the last paragraph mean?

A. Exciting.

B. Optimistic.

C. Disappointing.

D. Doubtful.

【4】How does the writer develop the passage?

A. By analyzing the research.

B. By classification of reindeer.

C. By comparing opinions of experts.

D. By telling stories of different species.

When my students ask me why I live in a tiny house, they ask it in light of all the “sacrifices(犧牲)”I an making. They know that I have moved from a large apartment in the city to a small custom-built home on wheels in the backyard woods. They know I forego running water, Internet connection, sewage(下水道), and reliable phone reception.
However, it was possible for me to be truly happy while living with very few material things. My body responded well, in health, fitness and mood, to a schedule more consistent(一致的)with the natural day and night cycle. Observing the daily sunset, hosting friends for days at a time, reading, writing letters to my families and friends and exploring natural wonders in my spare time all were free and invaluable experiences.
What was necessary to my survival proved to be a rather short list-healthy food, clean and drinkable water, heat source, weather-protecting shelter, weather-suitable clothing, equally important friends and mental and physical stimulations(刺激).
When I returned to life in the US, I couldn't help but sense a deep and uneasy belief that life suddenly changed. I felt disconnected with many things- the earth, others, my food source, my waste disposal, the natural cycle of my body and the productive interests. These are the things I once cared for but now find myself too busy to enjoy. How was it that I was earning literally 40 times my Peace Corps salary and was less healthy, satisfied and intentional in my daily schedule? I found myself asking-what is it to be rich anyway? Therefore, last August I let go of most of my possessions and moved into a tiny house on wheels because I wanted to see if I could live a more enjoyable lifestyle. So far so good. No inconvenience has made up for the many positive benefits that continue to come from this change in lifestyle. I believe that I have made the right decision.
（1）What does the underlined word “forego” in the first paragraph probably mean?
A.Give away.
B.Take along.
C.Care for.
D.Go after.
（2）What interested the author most when living in the tiny house?
A.The natural living schedule.
B.Busy and invaluable experiences.
C.The happiness of the simple life.
D.The very few material possessions.
（3）What did the author feel when he returned to the US?
A.He was behind the times.
B.He wouldn't enjoy the modern life.
C.He was rich enough to enjoy the city life.
D.He was disconnected with the outside world.

People lie all the time, but depending on how skilled they are, it can be difficult to determine when someone is lying to you. Do you know how to recognize the signs that someone is lying to you? Some of the signs are obvious while others are more subliminal(難以察覺的), but there are ways to catch someone in a lie, you just need to know what they are.
1） Liars make false eye contact.
A person who is lying to you won't make eye contact with you or they make too much eye contact. If a person is lying they may feel you are watching him and he will look down at the floor or away from your eyes. Some people try to stare you in the face deliberately.
2）Liars avoid using contractions(縮略形式)
The liar will say “I did NOT notice that.” instead of “I didn't notice that.” Usually it ends up making the story a lot less believable.
3）Unnatural Body Language.
Liars often feel uneasy, turn away from the person to whom they are speaking, blink(眨眼) rapidly, smile less and have pitch changes in their tone of voice. They may cross their arms which is a sign of being “closed” or trying not to reveal too much information. They could touch parts of their face, an ear or a nose or play with keys or another item that they have in their hand.
4）Liars provide additional information without being asked for it
The result is the more complicated the story is, the less believable it will be. You will have the feeling that nothing could be further from the truth.
A. This is an attempt by the liar to be absolutely clear what they mean.
B. Here are some easy ways to recognize liars and catch lies.
C. Sometimes people look unnatural when they are lying
D. They will get angry if you doubt their story
E. They seem to think that by telling their story in detail, you will find it more believable.
F. They try to change the subject or move the conversation in a different direction
G. In this way they feel like making eye contact will make what they are saying more believable.
