When I was a high school student，mathematics looked like a big barrier(障碍)for me and several of my classmates．Mr Iyer, a strict maths teacher，was also our class teacher．He always stuck to his discipline(纪律)．We had to arrive on time，pay undivided attention to his lectures, and dared not to ignore any of his homework．
Even so, as our class teacher, we got to know him better．Noticing some of us couldn't sit still and seemed restless one day as the midterm exams approached, he stopped solving a mathematical problem to ask us why．“There's too much to do，” we sighed．“We're afraid we'll never manage to finish our revision before the exam．”“Nothing is impossible．” Mr Iyer told us．“This classroom is on the second floor．Do you have a problem reaching here？” We reacted with blank stares．
“No，you don't！” he said, answering his own question．“You have a staircase(楼梯)to help you climb up to this level．No one expects you to make it in two giant leaps(跳跃)．You simply take one step at a time．Any task can be solved if you focus on the immediate action to be taken．The rest will take care of itself if you keep at it．One step at a time．That's the secret．” Then he wrote down an old motto on the blackboard—the longest journey starts with a single step．Having heard his staircase analogy(比拟), we understood why he asked us the question and we saw him in a new light．
Most of my classmates scored distinctions(成绩优异)in maths．And I went on to become an English teacher．To this day, whenever I pass on Mr Iyer's invaluable advice to my own students, they brighten up at the prospect of a lighter academic burden．

B．Take action quickly and make progress little by little．
C．It is important to make use of a good opportunity．
D．Don't hesitate to ask for help when meeting with barriers．
7．How does the author like Mr Iyer's advice

B．Incorrect and misleading．

Twenty-five years ago，most young Britons wanted a career in law，to be a doctor, or, if they were creatively minded, to take up singing．But today, things stand differently．
According to a survey by Tesco Mobile, a UK telecoms company, the “dream job” of young people aged between 16 and 25 in the UK is a video blogger, or “vlogger”．The survey, carried out among 1，002 people，found that as much as 40 percent of them put vlogger as their number one choice on a list of ideal jobs．
The only reason for this change is undoubtedly the Internet and social media．They have made it so much easier to reach a global user, without having to get a job in show business in the traditional way．
“In years gone by, the biggest stars were shaped and trained by the Hollywood studios; now, anyone with a computer camera can become an icon (偶像)，”a Tesco Mobile spokesperson said in a news release(发布会)．“These self-made stars record their hobbies to an admiring fan-base．Vloggers are the big stars of today because they are normal people interacting_with their fans about everyday life．”
However, what people see is only the great side of being a vlogger and they ignore the fact that only those who are successful get fame and fortune．There are the dreams that come true and the dreams that still remain dreams．
This is why although vloggers are popular, some young people choose jobs that don't necessarily earn them fame, but allow them to make good use of the Internet to share their hobbies．Young Israeli David Leshaw, for example, runs a business called the Finishers Club．It's an online platform(平台)for runners to keep a record of their races．He told the website Zippia that his job allows him to express his thought, and is always a learning experience．And that's enough for him．
8．What's the most popular job among British young people nowadays
A．A lawyer．　　　　　 B．A doctor．
C．A vlogger． D．A singer．
9．Why is it possible for anyone to become an icon these days
A．Because of the popularity of the computers．
B．Because the traditional show business has disappeared．
C．Because there are computer cameras for everyone to use．
D．Because the Internet and social media made it easy to reach a global user．
10．What's the meaning of the underlined word “interacting” in paragraph 4
A．Discussing． B．Forcing．
C．Communicating． D．Taking part in．
11．What's the author's opinion towards the vloggers
A．All vloggers can't be successful．
B．Vloggers should be supported．
C．Vloggers should be encouraged．
D．Vloggers are very helpful to society．
D
As we all know, all work and no play makes Jack a dull boy．Now scientists have given us another warning: spending too much time on smartphones or computers makes you dull too．
“Many focus on the benefits of digital devices (设备) in education but ignore the costs，” said Patricia Greenfield from the University of California, “losing the ability to understand the emotions of other people is one of the costs．” Greenfield and her research team did an experiment．They worked with 105 children who spent about 4．5 hours in front of screens on a school day．The students were asked to describe the emotions towards the pictures of people who were happy, sad, angry or scared．Then, half of them attended a five-day nature and science camp．There they had no smartphones, TV, or computers．The other half stayed in school and spent the five days as usual．Five days later, all the children took the test again．
Students who had been to the camp got about 5 percent more answers correct than they had done before the camp．But the other group of students didn't show much improvement．The study is not perfect in some ways, said the researchers．But scientists say that the study is still a warning for us．
“Emotional skills develop in practice and the brain develops through real interaction，” said Professor Taylor, a professor at the University of San Francisco．
Researchers talked to 2，000 parents of children aged 2-16 in the UK about what activities their children could do confidently．The results were surprising: Their children could use a tablet (平板电脑) (59%) and work a mobile phone (57%) more confidently than they could tie their shoe laces (鞋带) (53%)! So, spend more time away from mobile phones and computers if you want to be an understanding friend, and not a member of what the Daily Mail called “Generation Helpless”．
12．According to Professor Greenfield, what is the consequence of using digital media in education
A．Students don't get along well with family members．
B．Students always make more mistakes when taking exams．
C．Students can't catch up with others in schoolwork．
D．Students fail to know other people's emotions．
13．What do scientists think of the results of Greenfield's experiment
A．They are far from useful．
B．They are alarming for people．
C．They are quite surprising．
D．They need to be improved．
14．What can we learn from the text
A．Students learned how to describe emotions in the experiment．
B．Most of the UK children couldn't tie their shoe laces．
C．Students living without screens did much better in studies．
D．Overusing digital devices raised some worries．
15．What is the best title for the text
A．Stay Away from the Internet
B．Here Comes a Digital World
C．Screens Are Harmful to Emotions
D．How People Become Addicted

Days went by and the time came for the annual sports meet at the school．Charlie was also good at sports and he was participating in a number of events．Bill was participating in the sack race (套袋跑), though he could not run very fast due to his fat body．When Bill saw that Charlie won first prize in the 100-meter race, he felt very jealous (妒忌的) and decided that he would not let it happen in the sack race．

35．C　[根据下文“What I saw was a glowing child with a treasure．(我看到的是一个带着宝贝的欢快的孩子)”可知，此处用didn't notice与下文的saw形成对比。故选C项。]
【语篇解读】　本文是一篇夹叙夹议文。文章讲述了作者在西藏羌塘国家自然保护区看藏羚羊的经历，并呼吁保护野生动物、保护大自然。
36．plains　[考查名词复数。句意：我去了羌塘国家自然保护区观察藏羚羊，它们生活在西藏、新疆和青海的平原上。根据下文中“of Xizang，Xinjiang，and Qinghai”可知，此处指西藏、新疆和青海的平原。所以此处要用名词复数。故填plains。]
37．Watching　[考查非谓语动词。句意：看到它们在绿草地上缓慢移动，我被他们的美丽所震撼。分析句子可知，watch与句子主语I构成逻辑上的主谓关系，本句中已有谓语am struck，所以watch要用非谓语动词的动词ing形式，在句中作状语。因位于句首，所以首字母大写，故填Watching。]
38．illegally　[考查副词。句意：然而，因为它们有价值的皮毛，它们被非法猎杀。分析句子可知，设空处用来修饰动词were hunted，所以应该用副词形式illegally。故填illegally。]
39．a　[考查冠词。句意：保护区是西藏西北部动植物的一个避难所。shelter是可数名词，此处泛指“一个避难所”，且shelter 是以辅音音素开头的词，所以用不定冠词a。故填a。]
40．dropped　[考查时态。句意：藏羚羊的数量减少了50% 以上。根据上文时间状语“The 1980s and 1990s”可知，是在描述过去的事件，所以要用一般过去时。故填dropped。]
41．extinction　[考查名词。句意：为了保护这个物种不灭绝，中国政府将其置于国家保护之下。根据设空前的介词from，可知该空作其宾语，所以要用名词形式extinction，extinction是不可数名词。故填extinction。]
42．effective　[考查形容词。句意：这些措施是有效的。结合设空前的系动词were，可知设空处要用形容词作表语，所以填effective。故填effective。]
43．because/since/for/as　[考查连词。句意：然而，政府并不打算停止这些保护计划，因为对藏羚羊的威胁尚未消失。分析句子可知，设空处及之后的内容与设空前的内容构成因果关系，且是原因，所以用连词because/since/for/as。故填because/since/for/as。]
44．to protect　[考查非谓语动词。句意：为了保护野生动物，正在做很多工作。分析句子可知，设空处表示做许多工作的目的，所以此处要用不定式短语to protect表示目的，意为“为了保护野生动物”。故填to protect。]
45．with　[考查固定搭配。句意：只有当我们学会与自然和谐相处，我们才能不再对野生动物和我们的星球构成威胁。固定搭配in harmony with，表示“与……和谐共处”。故填with。]
