Internet shopping is a new way of shopping. People can shop for a variety of products on the Internet. Physical_products_include items such as books, CDs, clothes and food. These types of products are the most common purchases (购买品) through the Internet.
You can also buy information products such as online news or magazine stories, or you can download computer software through the Internet. Services such as booking airline tickets, booking hotels or renting cars are also available on the Internet. You can also go shopping on the Internet for entertainment services and take part in online games or e mail “chats”.
Internet shopping offers a number of benefits for the shopper. The most important one is convenience. You can shop when you like, as the online shops are open 24 hours a day, and you do not have to queue with other shoppers at the check out counters. Secondly, it is easy to find what you are looking for on the Internet. Even out of print books may be ordered online. Finally, it is often cheaper to buy goods through the Internet, and you can shop exactly what you want.
The main disadvantage of Internet shopping is that you cannot actually see the products you are buying or check their quality. Also, many people enjoy shopping in the city and miss the opportunity to talk to friends. Some people are worried about paying for goods using credit cards, so Internet companies are now finding ways to make online payment safe.
Internet shopping is sure to become more and more popular in the years ahead. It promises to change the way we buy all kinds of things — from tonight's dinner to a new car.

Ginger Sprouse first noticed Victor Hubbard on the corner of a street in late 2016. She'd drive past Hubbard at least four times a day but began to grow concerned about him when winter approached. Wondering what the man's story was, she decided to introduce herself.
She found out that Hubbard, who suffers from a mental illness, had been standing in the same spot his mother left him in for the past three years. He stayed there each day in the hope that his mother would come back for him.
Sprouse began visiting Hubbard on her lunch break. They quickly became friends. “I would drive up and he would always ask about me，” Sprouse said.
Sprouse was so moved by Hubbard that she created a Facebook page called “This is Victor” in December. She used the page so people could get to know Hubbard and help out. She'd post photos and videos of Hubbard enjoying the simple things in life. He soon stole thousands of people's hearts. Since the Facebook page was created, support has been pouring in for Hubbard. Someone gave Hubbard a free eye exam, while others provided food, clothes, a bike and a munity members also threw Hubbard a block party fundraiser (募集活动) with hundreds of attendees.
Sprouse's kindness didn't just help turn Hubbard's life around, but it helped him find his family. There's no doubt that Sprouse changed his life, but the influence isn't one sided. “He's changed me greatly because he never even, when he was standing on the corner wet and in the rain, had anything negative to say，” she said. “And if he can be as kind, sweet and positive in that situation, then I can be in whatever situation I'm in.”

Ⅲ.阅读理解
There's new evidence that too much screen time early in life can change the circuits (回路) in a growing brain. Scientists disagree, though, about whether those changes are helpful, or just cause problems.
The debate centered on a study of young mice exposed to a video game. “The mice showed big changes everywhere in the brain，” said researcher Ramirez. On the positive side, it meant that these mice were able to stay calm in an environment that would have stressed out a normal mouse. But it also meant they acted like they had a lack of attention, showed signs of learning problems, and were likely to do dangerous behavior. Generally, the results add to the evidence that parents should be very cautious about screen time for young children, Ramirez said.
A more positive explanation came from Professor Leah Krubitzer. “The benefits may be more important than the negative sides，” Krubitzer said, adding that a less sensitive brain might succeed in a world where overstimulation (过度刺激) is a common problem.
It's true that this sort of stimulation may make a child's brain less sensitive in some ways. But it also may prepare the brain for an increasingly fast paced world. “Less than 300 years ago we had an industrial revolution and today we're using mobile phones and we interact (互动) on a regular basis with machines，” Krubitzer said. “So the brian must have changed.”
Krubitzer rejected the idea that the best solution is to turn_back_the_clock. “You are likely to think of the good old days when you were a kid, and say, ‘I didn't do that and I didn't have TV and look how great I turned out，’” Krubitzer said.
Brain researcher Gina Turrigiano thinks lots of screen time may be fine for some young brains, but a problem for others. “Parents have to really realize the fact that each kid is going to respond very differently to the same kinds of environments，” she said.
语篇解读：本文是议论文。电子屏幕对孩子的大脑发育有损害，但同时也被高速发展的科技社会所需要。
1．What damage did the screen time cause to the mice
A．They have difficulty in focusing.
B．They are no longer afraid of danger.
C．They change their nature completely.
D．They get used to a stressful environment.
解析：选A 细节理解题。由第二段中的“they acted like they had a lack of attention, showed signs of learning problems, and were likely to do dangerous behavior”可知，这些老鼠的注意力下降，出现了学习障碍，以及有危险行为倾向。
2．Why do kids today need screen time according to Krubitzer
A．They are too sensitive to changes.
B．They learn how to succeed from it.
C．It is needed in social development.
D．It protects them from overstimulation.
解析：选C 推理判断题。由第四段中的“But it also may prepare the brain for an increasingly fast paced world”可推知，电子屏幕虽然有害，但是这个高速发展的科技社会需要大脑也做出一些改变来适应。
3．What does the underlined part “turn back the clock” in Paragraph 5 mean
A．Stay away from screens.
B．Forget the good old days.
C．Behave younger and healthier.
D．Change the time shown on the clock.
解析：选A 词义猜测题。由画线部分之后的“think of the good old days when you were a kid ...I didn't do that and I didn't have TV and look how great I turned out”可知，turn back the clock是指回到过去没有电子屏幕的生活。
4．What does Gina suggest parents do in the last paragraph
A．Learn more from each other.
B．Don't limit screen time for their kids.
C．Be cautious about screen time for their kids.
D．Encourage their kids to learn more from screens.
解析：选C 推理判断题。由最后一段Gina说的话可推知，相同的面对屏幕的时间对于不同的孩子来说影响也不同，所以父母们不能轻率地做出决定。
Ⅳ.阅读七选五
Imagine that you are in a remote village somewhere with no medical clinic. __1__ Once the doctors get to you, they examine you and take blood samples, but they won't be able to help you until they take the samples back to the hospital to find out what is wrong. __2__ Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic (诊断的) tool.
Ozcan's invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, don't have enough training to correctly interpret what they see. __3__ With Ozcan's mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at a hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes.
__4__ His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.
By inventing a medical tool that uses existing technology — mobile phones, Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effective almost anywhere. __5__
A．Another reason why Ozcan's invention is important is that it is inexpensive.
B．Even though you may only have a simple infection (感染), you might die because of the delay.
C．People are trying to reduce the cost of this new medical tool.
D．Ozcan's simple, cost effective tool might just save millions of lives around the world.
E．This tool has become much more popular all around the world.
F．You become very sick and must wait days until a mobile medical unit arrives to help.
G．As a result, they may diagnose illnesses incorrectly.
语篇解读：本文是一篇说明文。在偏远地区，医生救助病人比较困难，工程师Andy Ozcan发明的诊断疾病的工具——一种手机软件——解决了这一难题。该工具仅需手机和网络连接，成本低廉，使用简单。
1．解析：选F 根据空前一句并结合常识可知，假如你在一个没有医疗诊所的偏远村庄并且病得很重，你也必须等待数天才能得到帮助，故F项与上文衔接紧密。
2．解析：选B 根据空前的“Once the doctors get to you ... to find out what is wrong”可知，医生到达后检查你的身体并采集血样，但是他们无法立即帮助你，直到他们把血样带回医院去检测哪儿出了问题；据此可知，即便你只是患有普通的感染，你也可能会因为延误而死，故B项正确。
3．解析：选G 根据空前一句可知，例如，许多医生因训练有限而无法正确诊断他们所看到的病情；因此，他们诊断出的疾病可能会不准确，故G项与此处匹配。
4．解析：选A 根据空处所在的位置可知，空处为该段的主题句；由该段内容及第二段第一句可知，该段主要说明这个发明很重要的另一个原因，故A项正确。
5．解析：选D 根据该段内容尤其是“Therefore, it can be effective almost anywhere”可知，由于经济实用，这个发明几乎可以在任何地方使用；据此可知，这种简单且合算的产品将可能挽救全世界数百万人的生命，故D项正确。课时跟踪检测（四）Project

Email is a great way of sending an anonymous (匿名的) message.In seconds one can create a new email account that easily masks the true identity of the account holder.When messages are sent with this account, the receiver will have no idea who sent the messages.Sometimes such messages are harmless ads for a variety of products. At times, however, these anonymous emails can be disturbing.
When first faced with an annoying email message, the receiver's first reaction may be to try to find out who sent it. Many people believe that there is no database of email addresses available to them.While this may have been the case during the early days of the Internet, it is no longer true today.
There is now a legitimate (合法的) process available to trace the origin of an email.It's called “Reverse Email Lookup”. One might think that such an important service would be extremely expensive, but the opposite is the case.Reverse email searches, if performed by the proper company, can be very affordable.
Online security is an extremely pressing issue that affects every computer user.If someone sent an email, how did they get the address？Who are they？What are their intentions？A reverse email search can begin to address these important security concerns.
Many people are beginning to take advantage of reverse email searches and statistics show that more and more people are using this service.Again, in today's security conscious world, many people merely want to know who is sending emails.Viruses and malware (恶意软件) are sent by email, so experienced computer users will not open an email from an unknown source.A reverse email search can help prove that a received email is legitimate.
语篇解读：当今互联网时代 ，匿名邮件无处不在。如何弄清这些邮件是从哪里发出的呢？那就使用一项新的发明——“反向邮件查找”服务吧。

语篇解读：本文是一篇夹叙夹议文。马可·波罗在17岁时就随父亲和叔叔来到中国，看到了中国那时的发展情况。七百多年后的今天，中国以其快速的发展和在世界上日益重要的地位吸引了更多人。
1．off/out 考查动词短语。该句意为：这三个人踏上了一条可能连最雄心勃勃的旅行者都害怕的道路。set off/out为固定短语，意为“启程，出发”，故可知答案。
2．travelled/traveled 考查动词的时态。根据第一段第一句中的时间状语“More than 700 years ago”可知，此处讲述的事情发生在七百多年前，故用一般过去时。
3．to record 考查动词不定式。一路上，他停下来详细记录当地的风俗、地理和人们的价值观，以便向可汗汇报。根据语境可知，空处表示停下来的目的，故用动词不定式作目的状语。
4．countless 考查形容词。根据语境可知，他从东方带回了无数的珍宝，一夜之间成了富翁。空处修饰名词treasures，故用形容词形式，再根据语境可知，应填countless，表示“数不尽的”。
5．a 考查不定冠词。该处泛指“一位富翁”，且wealthy的发音以辅音音素开头，故用不定冠词a。
6．What 考查主语从句。分析该句结构可知，空处引导主语从句，也在从句中作及物动词witnessed的宾语，故用What引导该主语从句。
7．vividly 考查副词。空处修饰动词written，故用副词形式。
8．was thought 考查时态和语态。which指代The Travels of Marco Polo，为从句的主语，且该主语和动词think之间是被动关系，故用被动语态；再根据前文时态可知，应用一般过去时。
9．following 考查非谓语动词。a Westerner和动词follow之间是主动关系，且该处作后置定语，故用动词 ing形式。
10．development 考查名词。空前的形容词rapid修饰空处，且空处与后面的importance并列，故空处用名词形式。课时跟踪检测（一）Welcome to the unit & Reading — Language points

Ⅳ.阅读理解
While Jennifer was at home taking an online exam for her business law class, a monitor (监控器) a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer's Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room.Her Internet access was locked — remotely — to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past Or was she slowing down
In the battle against cheating, this is the cutting__edge and a key to encourage honesty in the booming field of online education.The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven't just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of “open online courses”. Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high tech methods are becoming increasingly popular. Among them are programs that check students' identities using personal information, such as the telephone numbers they once used.
Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.

Ⅴ.阅读七选五
Lexi bumped into someone at the mall. Ryan tripped over a bag at the airport. You've probably seen it, and maybe you've even laughed: __1__ Believe it or not, people can also get hurt. The American College of Emergency Physicians warns people about texting on the move.
The problem is multitasking (多重任务执行). The human brain can't do several things at once and give full attention to all of them. __2__ When you text you're thinking about what to say, concentrating on what your thumbs are doing, and reading constantly incoming messages rather than paying attention to what you're doing or where you're going. And that increases your risk of getting hurt or injuring others.
__3__ Even if texting feels like second nature, your brain is still trying to do two things at once — and one of them will get less attention.
Texting also prevents you from paying close attention to what's going on around you, something that's especially important in situations where you need to have your guard up. __4__ If you're about to run into someone or something else, you may not have time to act before it's too late.
To avoid an injury, try to use your best judgment. __5__ And if you're riding in a car with a driver who is texting, ask him or her to stop or try not to ride with that person again.
A．Text only when you're not putting yourself or others in danger.
B．When people text while driving, they're not focusing on the road.
C．Your reaction time is likely to be much slower when you're texting.
D．So manage how and when we text, choosing the right time and place.
E．It doesn't matter whether you can text without looking at the keypad.
F．So you can get into danger if you try to text in situations that require your full focus.
G．People can end up in foolish situations when they text and walk at the same time.
