ON LOCATION

VINTAGE FINDS
If your teens are keen to develop their vintage (复古的) rock style，take them to Park Street to discover the vintage shops，including Uncle Sam's Vintage，perfect for everything from American varsity (校队) jackets to Levi's jeans，as well as The Vintage Thrift Store，Loot Vintage and Sobeys．
1．Why does the author recommend Bristol
A．Because it is easier to learn art here．

Just a year ago，Sarah fulfilled the dream of owning her own bakery，which was very popular in the local and provided a well-off life for Sarah and her family．But last February，all fell apart，after a car accident left Sarah disabled． “I could barely talk or move，” she sobbed．
Darkness and depression drowned Sarah，help seemed out of reach; she couldn't afford a psychologist．Even worse，she had no health insurance．
So her doctor suggested a mental-health app which offers free chatbot service．It is described as a “friendly” and “mental” tool，asking the patient some questions，like “How are you feeling？” or “What's bothering you？” After the patient responds to the questions，the computer analyzes the words and phrases in the answers，and then delivers supportive messages which have been pre-written by trained human psychologists．
That is how Sarah found herself on a new frontier of technology and mental health．Advances in artificial intelligence are increasingly being looked to as a way to help people who suffer from mild depression or anxiety．
There are，of course，still plenty of doubts about whether machines can read or respond to the human emotions accurately．“Artificial intelligence is still not at a point where they can copy the complexities of human emotions，let alone imitate mental care，” a psychology professor in a mental health center said．
However，supporters of chatbot treatment say the approach may also be the only realistic and affordable way．It meets a huge worldwide need for more mental healthcare at a time when there are simply not enough professionals to help all the people who could benefit．
4．What can we know about Sarah from the first two paragraphs
A．Her family fell apart in an accident．
B．She was nearly drowned in an accident．
C．She suffered a series of misfortunes then．

Ⅲ．【语篇解读】 本文是一篇应用文。文章主要介绍了在布里斯托尔，可以让十几岁的青少年喜爱的购物和沉浸式艺术。
1．C [细节理解题。根据“MAKING THEIR MARK”部分中的“You won't have to rack your brains to encounter the handiwork of the city's famous one，because there are more than 200odd street artists in the city where The Wall offers a twohour tour of the mustsee works and Bristol's 30 years of graffiti history．There are spraypainting workshops too，if your teens want to give it a shot．”可知，Bristol这座城市有200多名街头艺术家，在这里能看到这座城市著名的涂鸦艺术家的作品。由此可知，作者推荐Bristol是因为这里有很多伟大的艺术家和作品。故选C。]
2．C [细节理解题。根据文章内容可知，在Bristol，青少年可以参观Bristol 30年辉煌的涂鸦历史，在Wake the Tiger体验奇幻世界，接触电影地图以及购买复古牛仔裤。C选项“Encounter famous film stars．(遇到著名的电影明星)”没有提到。故选C。]
3．B [推理判断题。根据第一段中的“spend your holiday with your kids effectively”“stimulate your kids' interest”以及“satisfy your teens' desire” 可推知，本文面向的目标读者是十几岁青少年孩子的家长们。故选B。]
【语篇解读】 本文是一篇说明文。文章通过莎拉的例子介绍了一款提供免费聊天的机器人服务，介绍了聊天机器人的工作方式以及人们对此的看法。
4．C [细节理解题。根据第一段中的“But last February，all fell apart，after a car accident left Sarah disabled．‘I could barely talk or move，’ she sobbed．”和第二段“Darkness and depression drowned Sarah，help seemed out of reach; she couldn't afford a psychologist．Even worse，she had no health insurance．”可知，莎拉遭受了一连串的不幸。]
5．D [细节理解题。根据第三段“...asking the patient some questions，like ‘How are you feeling？’ or ‘What's bothering you？’ After the patient responds to the questions，the computer analyzes the words and phrases in the answers，and then delivers supportive messages which have been prewritten by trained human psychologists．”可知，聊天机器人通过预先存储相关信息工作。]
6．B [推理判断题。根据倒数第二段中的“‘Artificial intelligence is still not at a point where they can copy the complexities of human emotions，let alone imitate mental care，’ a psychology professor in a mental health center said．”可知，人们会怀疑聊天机器人是因为它可能无法对人类的情绪作出正确的反应。]
7．A [推理判断题。根据第三段中的“So her doctor suggested a mentalhealth app which offers free chatbot service．”并通读全文可推知，这篇文章的写作目的是介绍一款免费的心理护理聊天机器人。]
Ⅳ．【语篇解读】 本文是一篇说明文。文章主要介绍了作者对2050年的生活展开的预测，主要有四点：每个人都可以免费使用网络，私人飞机会被广泛应用于短途行程，大多数癌症会被治好，人类会居住在其他星球上。
1．B [上文“So where is technology going in the future？”提出一个问题，未来的科技将走向何方？下文是对未来的一些预测，故B项“让我们开始我们的预测吧”承上启下。]
2．A [根据上文“There have already been attempts like Facebook's Free Basics．”及下文“there is a very strong possibility that the Internet will be free for everyone in the future”可知，未来互联网对每个人都是免费的可能性很大，故设空处是说目前互联网还没有对所有人免费，A项“虽然它还没有发生”符合语境。]
3．F [根据下文“so in this case personal airplanes will be a handy method of transportation for common people”可知，设空处与下文是因果关系，应在描述是什么导致私人飞机成为普通人的交通方式，结合选项，F项“道路上的交通将会更加繁忙”符合语境。]
4．G [根据本段主题句“Most cancers will be treated successfully．”及下文“It will be a huge achievement in the history of medical science．”可知，大多数癌症都会被成功治疗，所以癌症造成的死亡人数会下降，这将是医学史上的一项巨大成就，G项“癌症造成的死亡人数将大大减少”符合语境。]
5．E [根据本段中“In the year 2050，humans will be able to live on Mars．”可知，本段是讲述关于未来在其他星球上居住的，E项“人类将居住在其他星球”符合语境。]
