Every time we get behind the wheel of a car, we put our lives and the lives of others at risk. Self-driving cars are designed to reduce those risks by letting technology control our vehicles.

    Accident rates for self-driving cars have been much lower than the rate, for human-driven cars. {#blank#}1{#/blank#}

    As humans, we can make moral choices in avoiding accidents. To avoid hitting a child, for example, human drivers might sharply turn a car away from the child even if others may be injured. {#blank#}2{#/blank#} Researchers studied this issue. They have developed the Moral Machine website to help explore the choices self-driving cars should make.

    {#blank#}3{#/blank#} You are shown two possible traffic situations and you choose between them. An accident will take place. You choose how many living beings would be hurt or killed.

    In one situation there may be a female doctor, a child, two dogs and a homeless person who would be killed. In the other situation, you might have two babies and a cat who would be killed. {#blank#}4{#/blank#}

    The Moral Machine website has many situations and many possible outcomes. When you click on the situation of your choice, it will be highlighted. {#blank#}5{#/blank#} At the end of the situation, you are shown the results, based on the choices you made. The results show which character you were most likely to save and which character you were most likely to have die.

    Do you know how to pick a good book you'll really like? Here are some tips.

Start With Your Interest. {#blank#}1{#/blank#}. You can pick something that you love to read, not for school. They can be ancient martial (武术) arts, computers, or fashion design. You name it, there are books about it.

    What's Your Type? Do you prefer fiction or nonfiction (or both)? Fiction books, like novels, can transport you to another world or help you imagine something beyond your own experience. Nonfiction books give you the who, what, when, and why of something. {#blank#}2{#/blank#}. Many of them read like novels from start to finish.

       Read the description. The reviews and quotes on the back and inside covers of many books give you an idea of what the book is about. They can also help you pick future books, too. If you find a book you really like, take a minute to read the quotes and see which authors praised the book. {#blank#}3{#/blank#}.

    Find a Family Favorite. Which book did your mother love best when she was at your age? {#blank#}4{#/blank#}. Find out and give them a read — then you can share your thoughts about the book.

    A global cyberattack, which is considered the biggest cyberattack ever, is spreading quickly and widely.{#blank#}1{#/blank#}

    What the attack does

    Cyber bad guys have spread ransomware(勒索软件), known as WannaCry, to computers around the world. It locks down all the files on an infected computer. The hackers then demand $300 in order to release control of the files.{#blank#}2{#/blank#}

    How it happened

    WannaCry takes advantage of a vulnerability(弱点) in Microsoft Windows. Microsoft released a security patch for the vulnerabilities in Marclf. {#blank#}3{#/blank#} Playing with fire finally caught up with the victims.

    Microsoft requires Windows 10 customers to automatically update their computers, but some people with older PCs disabled automatic updates.

    {#blank#}4{#/blank#}

    The attack has been found in 150 countries, affecting 200,000 computers, according to Europol, the European law enforcement agency. FedEx, Nissan, and the United Kingdom's National Health Service were among the victims. In the U.K., hospitals were crippled by the cyberattack, which forced operations to be canceled and ambulances to be diverted.

    Who is vulnerable

    {#blank#}5{#/blank#}Microsoft said it had taken the "highly unusual step" of releasing a patch for computers running older operating systems including Windows XP, Windows 8 and Windows Server 2003. So even people with older computers should update them.

    Apple's Mac computers were not targeted by this ransomware attack. Bad guys generally target Windows far more than Apple's operating system because there are vastly more computers running Windows around the world.

A. When it will be solved

B. How widespread the damage is

C. That's why it's called ransomware.

D. The hackers remain anonymous for now.

E. Here is a super-simple explanation of what's going on.

F. Anyone who hasn't updated their windows PC recently is easy to attack.

G. But many corporations don't automatically update their systems.

    Learning a foreign language can be interesting. {#blank#}1{#/blank#} In order to increase your chances of success, it is important to consider which method of language learning will provide you with the most benefits. So think about the three ways of learning a language: self­study at home, attending classes and online courses.

    The main disadvantage of learning by yourself is that there is no one available to answer your questions. One way to deal with this is to make a list of your questions and ask for the help of a native speaker of the language regularly. {#blank#}2{#/blank#}

    Learning a foreign language in a classroom is probably the most popular choice. The regularity(规律性) of the lessons will encourage you to attend classes. {#blank#}3{#/blank#} In most cases, the enthusiasm of the other students may also encourage you to make progress.

    Online learning is the newest method of learning a foreign language. It suits both the students who prefer to learn alone and the students who may prefer to attend a class but are unable to do so. {#blank#}4{#/blank#} It is also possible to ask questions and to communicate with other students online.

    Whichever method you choose, keep in mind the reasons why you are learning the language. {#blank#}5{#/blank#} This will help you stay focused throughout the learning process.

A.Many students prefer to learn by themselves.

B.But it can also be difficult, frustrating and boring.

G.Your personality should be considered when deciding which method of learning to use.

Effective Ways to Protect Our Planet

We only have one earth. However, humans haven't been very good protectors of the earth over the years. To leave a fine planet for our children and future generations, we all need to take steps to develop better living habits. {#blank#}1{#/blank#}

Buy less. Cheap goods in the sales may make your life better, but few of those are essential. And they almost always end up in the trash can or are forgotten in the back of a. closet. So next time you're hesitating about buying or accepting a non-essential item, think over whether it will truly improve your life. {#blank#}2{#/blank#}

Turn waste into treasure. {#blank#}3{#/blank#} Not only does it keep items out of trash cans, but it can also prevent you from buying new items, which require lots of resources to produce. Moreover, children love making things. So instead of heading towards the craft store, check out your recycling bin first and improve your children's imagination.

{#blank#}4{#/blank#}Did you know it takes over 700 gallons of water to grow enough cotton to make just one plain T-shirt? Instead of going to the mall to buy new clothes, you can consider looking first in a secondhand shop or trading clothes. Second-hand shopping also applies to many other categories of consumer goods such as furniture, cars and children's toys.

Walk, bike or car sharing.According to the Environmental Protection Agency (EPA), a typical passenger vehicle emits (排放) about 4.6 metric tons of carbon dioxide (CO₂) per year. Thus, any amount of what you can cut back on will matter. For short trips, you can try walking or biking. {#blank#}5{#/blank#} If travelling on foot or by bike isn't practical, you can try carpooling with a friend, neighbour or coworker to the same destination.

A. Save water.

B. Choose second-hand stores.

C. If not, it's okay to just say, "No, thanks!"

D. And here are some ways to protect the environment.

E. Plastic bottles are a clear example of waste material.

F. In this way, you can get some exercise without going to the gym.

G. Creating something new with unwanted items is a good way to protect the environment.
