Kids as y 1 as six are being signed up for coding (代码) classes. Are they too young to learn to program? We interviewed three parents. Let’s hear what they think. ◆Martin In my opinion, schools and parents shouldn’t introduce coding to kids. Those who have are missing several important points. Bill Gates and Marissa Mayer didn’t become s 2 because they could code. Instead, they succeeded because they were creative thinkers. Although technology has greatly developed over the years, raising children hasn’t c 3 much. Children thrive (茁壮成长) when they have parents who teach them important values and life skills. Kids shouldn’t spend all of their time in front of a s 4 . They should spend more time with their parents and friends. ◆Edward Through learning how to code, kids learn “computational” thinking. “Programming is a(an) u 5 skill, and computational thinking is an important ability. Those who can properly make use of the p 6 of computer have an advantage over those who can’t. Therefore, I think that in the 21st century, every kid should learn to program. ◆Christa I think kids should be introduced to computer science. However, before they learn to code, kids should f 7 learn ethics (道德准则). They need to understand how a single program can cause serious damage on the Internet within minutes. 【答案】1．(y)oung 2．(s)uccessful 3．(c)hanged 4．(s)creen 5．(u)seful 6．(p)ower 7．(f)irst 【导语】本文介绍了几位家长对孩子们学习计算机编程的观点。 1．句意：年仅六岁的孩子正在报名参加编程课程。根据“Are they too young to learn to program?”和首字母y可知，此处表示小到六岁的孩子，young“幼小的”，as+形容词或副词的原级+as，表示“和……一样……”，故填(y)oung。 2．句意：比尔·盖茨和玛丽莎·梅耶尔之所以成功，并不是因为他们会编程。根据“Instead, they succeeded because they were creative thinkers.”可知，他们是成功的，successful“成功的”，作为系动词become的表语，用形容词，故填(s)uccessful。 3．句意：尽管这些年来科技有了很大的发展，但抚养孩子的方式并没有太大变化。结合句意和首字母c可知，尽管技术有了很大发展，抚养孩子的方式应是没有很大变化，change“变化”，根据“hasn’t”可知，此处用现在完成时，因此用change的过去分词，故填(c)hanged。 4．句意：孩子们不应该把所有的时间都花在屏幕前。根据“In recent years, more and more people have started to learn computer programming.”和首字母s可知，此处介绍家长对孩子们学习电脑编程的观点，应是孩子们在屏幕前，screen“屏幕”，故填(s)creen。 5．句意：编程是一项有用的技能，编程思维是一项重要的能力。根据“and computational thinking is an important ability.”和首字母u可知，编程是有用的技能，useful“有用的”，是形容词，修饰名词skill，故填(u)seful。 6．句意：那些能恰当地利用计算机力量的人比那些不能利用计算机的人有优势。根据“Through learning how to code, kids learn ‘computational’ thinking.”和首字母p可知，通过学习编程，孩子们学会编程思维，因此有计算机力量，power“力量”，故填(p)ower。 7．句意：然而，在他们学习编程之前，孩子们应该首先学习道德。根据“before they learn to code”和首字母f可知，在学习编程之前，应是先要学习的东西，first“最先的”，故填(f)irst。 Read the passage and fill in the blanks with proper words (在短文的空格内填入适当的词，使其内容通顺。每空格限填一词，首字母已给。) The fast development of technology has made many changes in our daily life. Some people believe that schools will not be necessary in the near f 1 . They say that because of the Internet and other new technology, there is no need for school buildings, classes or teachers. P 2 this will be true one day, but if the world had no schools, I couldn’t imagine how our society would be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school that is linked (连接) to libraries, museums, science centres, labs and even companies. Companies should c 3 learning programmes for schools. Scientists could give talks through the Internet. TV networks and local TV stations could develop programmes about the students who are studying at school. Labs could set up websites to s 4 new technology so that students could see it on the Internet. Is this a daydream? No. This is beginning to happen in many cities. In those cities, learning can take place at home, at school and in the o 5 . Businesses provide programmes for schools and society. Schools provide computer labs for people with their own computers at home. Everyone can visit faraway libraries and museums as easily as nearby ones and everyone can go on the Internet, and older people use it as much as y 6 ones. How will this new kind of school change the usual way of learning? It is too early to be sure, but it is fantastic to think about it.

These devices offer us convenience as well as connection and a lot of information. H 1 , it’s also easy to feel pressured to keep up with every message. More and more people want to take a break from technology. The phrase “digital detox” describes staying away from TV, phones, computers and other forms of technology that c 2 our lives for a period of time. These breaks can occur in a variety of ways.

A third option is logging out in evenings and/or on w 4 . Others simply turn their phones off. Some even pay high prices to take vacations in places where they can take time out from technology. Why do you want to take a digital detox? Perhaps you find that you are spending longer than you plan on certain apps or that they distract you from more important things. Perhaps social media is depressing because you compare yourself to others or you f 5 missing out on things that other people are enjoying. Technology can also have p 6 effects. Many people experience back or neck pain and the blue light coming from most screens can also affect people’s sleep. On one research trip, a group of people agreed to spend four days w 7 their smartphones. By the time the phone-free period ended, many people in the group had made important decisions about their work or relationships. Others had decided to live a healthier lifestyle.

Kids as y 1 as six are being signed up for coding (代码) classes. Are they too young to learn to program? We interviewed three parents. Let’s hear what they think. ◆Martin In my opinion, schools and parents shouldn’t introduce coding to kids. Those who have are missing several important points. Bill Gates and Marissa Mayer didn’t become s 2 because they could code. Instead, they succeeded because they were creative thinkers. Although technology has greatly developed over the years, raising children hasn’t c 3 much. Children thrive (茁壮成长) when they have parents who teach them important values and life skills. Kids shouldn’t spend all of their time in front of a s 4 . They should spend more time with their parents and friends. ◆Edward Through learning how to code, kids learn “computational” thinking. “Programming is a(an) u 5 skill, and computational thinking is an important ability. Those who can properly make use of the p 6 of computer have an advantage over those who can’t. Therefore, I think that in the 21st century, every kid should learn to program. ◆Christa I think kids should be introduced to computer science. However, before they learn to code, kids should f 7 learn ethics (道德准则). They need to understand how a single program can cause serious damage on the Internet within minutes.

Some people believe that schools will not be necessary in the near f 1 . They say that because of the Internet and other new technology, there is no need for school buildings, classes or teachers. P 2 this will be true one day, but if the world had no schools, I couldn’t imagine how our society would be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school that is linked (连接) to libraries, museums, science centres, labs and even companies. Companies should c 3 learning programmes for schools. Scientists could give talks through the Internet. TV networks and local TV stations could develop programmes about the students who are studying at school. Labs could set up websites to s 4 new technology so that students could see it on the Internet. Is this a daydream? No. This is beginning to happen in many cities. In those cities, learning can take place at home, at school and in the o 5 . Businesses provide programmes for schools and society. Schools provide computer labs for people with their own computers at home. Everyone can visit faraway libraries and museums as easily as nearby ones and everyone can go on the Internet, and older people use it as much as y 6 ones. How will this new kind of school change the usual way of learning? It is too early to be sure, but it is fantastic to think about it. Technology will change the way we learn; schools will change as w 7 ; and we will all learn something from the Internet.

More and more people want to take a break from technology. The phrase “digital detox” describes staying away from TV, phones, computers and other forms of technology that c 2 our lives for a period of time. These breaks can occur in a variety of ways. Some experts suggest completely avoiding u 3 screen time for 30 days. Others suggest using an app that will limit the amount of time one can spend on certain websites. A third option is logging out in evenings and/or on w 4 . Others simply turn their phones off. Some even pay high prices to take vacations in places where they can take time out from technology. Why do you want to take a digital detox? Perhaps you find that you are spending longer than you plan on certain apps or that they distract you from more important things. Perhaps social media is depressing because you compare yourself to others or you f 5 missing out on things that other people are enjoying. Technology can also have p 6 effects. Many people experience back or neck pain and the blue light coming from most screens can also affect people’s sleep. On one research trip, a group of people agreed to spend four days w 7 their smartphones. By the time the phone-free period ended, many people in the group had made important decisions about their work or relationships. Others had decided to live a healthier lifestyle. Only when they took a break from technology could they think about really important things. Giving up all screens may not be realistic, but strategic breaks from technology my be good for your body, mind, emotions and relationships. 在短文的空格内填入适当的词使其内容通顺。每空格限填一词，首字母已给出 In many parts of the world, university students work in summer.

Clearly, we can’t cover every piece of land on the planet with data centers. So where can we store all of this data? Fortunately, some researchers have been working on new storage technologies. One of these technologies is DNA storage. DNA storage sounds futurist, but in some ways, it’s just the opposite. B 4 computers were invented, nature had been using DNA to store information. In 2012, researchers at Harvard University wrote a book, 11 pictures and a computer program into human DNA．Each gram of DNA can hold 2.2 petabytes (PB．of information (1 ZB =1,048,576 PB．If DNA is kept in the right condition, it can keep the stored information s 5 for a million years.
