    This month, Germany's transport minister, Alexander Dobrindt, proposed the first set of rules for autonomous vehicles(自主驾驶车辆). They would define the driver's role in such cars and govern how such cars perform in crashes where lives might be lost.

    The proposal attempts to deal with what some call the “death valley” of autonomous vehicles: the grey area between semi-autonomous and fully driverless cars that could delay the driverless future.

    Dobrindt wants three things: that a car always chooses property(财产) damage over personal injury; that it never distinguishes between humans based on age or race; and that if a human removes his or her hands from the driving wheel — to check email, say — the car's maker is responsible if there is a crash.

    “The change to the road traffic law will permit fully automatic driving,” says Dobrindt. It will put fully driverless cars on an equal legal footing to human drivers, he says.

    Who is responsible for the operation of such vehicles is not clear among car makers, consumers and lawyers. “The liability(法律责任) issue is the biggest one of them all,” says Natasha Merat at the University of Leeds, UK.

    An assumption behind UK insurance for driverless cars, introduced earlier this year, insists that a human “ be watchful and monitoring the road” at every moment.

    But that is not what many people have in mind when thinking of driverless cars. “When you say ‘driverless cars', people expect driverless cars.”Merat says. “You know — no driver.”

    Because of the confusion, Merat thinks some car makers will wait until vehicles can be fully automated without operation.

    Driverless cars may end up being a form of public transport rather than vehicles you own, says Ryan Calo at Stanford University, California. That is happening in the UK and Singapore, where government-provided driverless vehicles are being launched.

    That would go down poorly in the US, however. “The idea that the government would take over driverless cars and treat them as a public good would get absolutely nowhere here,” says Calo.

    Jack threw some papers on my desk and looked at me angrily. “What's wrong?” I asked. “Next time you want to change anything, ask me first,” he shouted and left.

    “How dare he treat me like that?” I thought. I had just changed one long sentence, and correct grammar—something I thought I was paid to do. In fact I had been warned. On the first day one of  my workmates took me aside and reminded me of his temper. As the weeks went by, I came to look down on Jack.

    One day Jack's other papers left me in tears so I stormed into his office angrily. “What?” he asked.

    Suddenly I knew what I must do. After all, he earned it. “Jack, the way you've been treating me is wrong. I've never had anyone speak to me that way. As a professional, it's wrong for me to allow it to continue,” I said. Jack smiled nervously, “Susan, I make you a promise that I will be a friend. I will treat you as you should be treated, with respect and kindness,” he said. With these words, I left.

    Jack avoided me the rest of the week, and never questioned my work again. I brought cookies to the office one day and left some on his desk. Another day I left a note: “Hope your day is going great.” Over the next few weeks, Jack reappeared , but there were no more Jack's papers. One year later I discovered I had breast cancer, and was scared. The statistics (统计数字) were not great for my long-term survival.

    On the last day of my hospital stay, Jack came and silently handed me a bundle with several bulbs inside. “Tulips (郁金香) ,” he said. I smiled, not understanding. He cleared his throat. “If you plant them when you get home, they'll come up next spring. I think you will be there to see them when they come up.” Tears clouded my eyes and I whispered: “Thank you.”Jack held my hands firmly, saying, “You are welcome. You can't see it now, but next spring you will see the colors I picked out for you.”

    I have seen those red and white striped（有条纹的） tulips push through the soil every spring for over ten years now. This past September the doctor declared me cured. At a moment when I was praying for just the right word, a man with very few words said all the right things. After all, that's what friends do.

    What do you think of cats? Some people think very lovely. But not all people love cats. Compared with dogs, cats seem to be very lazy and unfriendly. Besides, cats are not known for acts of selflessness (无私). But maybe we're wrong about them. Don't believe it? Then meet Pippa, a very unusual cat.

    The black-and-white cat was left in a box outside a shop and taken by the British RSPCA to the Jansa family in Whitstable, Kent. They really loved her character (性格) and decided to adopt (收养) it，but they never guessed she'd become a lifesaver.

    Eight-year-old Mia Jansa had diabetes and had become good at testing her blood during the day, as well as having something to eat or drink to bring her blood sugar levels back. But the danger was at night. Mia could easily experience hypoglycemic (低血糖症的) situations when she was asleep, which could cause even death.

    Soon after she was adopted, Pippa went into Mia's bedroom in the middle of the night and woke her up. When the child tested her blood sugar levels, she found they were dangerously low. Ever since, Pippa always visits Mia at night. If she can't get her to wake up, she raises the alarm.

    “Pippa does this of her own accord,” says Mia's mother Laura. “We don't make a request for caring because we don't want to encourage wrong alarms. She gets plenty of hugs. It gives me peace of mind and I know someone else is keeping an eye on Mia.”

    Now the family is so happy that they've chosen to adopt it in the first place.

    If you are interested in studying at an American university, you have to take the Test of English as a Foreign Language. The test is widely known as the TOEFL. It is the most widely used language exam for American universities.

    There are two major kinds of the TOEFL test. The first is the IBT, or Internet-based Test. It is offered in most of the world and accepted by nearly every university and scholarship program in the United States. The other kind of the test is called the Paper-based Test or PBT. The PBT is less costly to take and does not require use of the Internet.

    But how to get started with TOEFL? Here are some tips.

⒈Plan ahead —It takes a long time to improve your TOEFL score. Do not expect a big lift in your test results after two weeks. You will have to spend a lot of time and energy.

⒉Master the basics first —You should have to be good at basic English before you take the test. If you score below 500 on the PBT or 70 on the IBT, study for a few months and come back to the TOEFL later.

⒊Get a study guide — It is easy to find study guides for the IBT. Pearson, Barron's, ETS, and Kaplan all produce quality materials. Take a practice test once or twice a month. The best study guides will have explanations in the answer key.

⒋Use outside resources — Remember, you are learning a language, not a test. You can improve your TOEFL score by making English part of your daily life. Some simple ways are listening to English speakers, watching movies and reading newspapers. Some others are reading English textbooks, sending and reading text messages in English, and writing online in English.

    The best way to do well on the TOEFL is to know English well. The real goal of the test is to measure how well a student can communicate in English-speaking classroom.

    There is more of a connection between food and culture than you may think. On an individual level, we grow up eating the food of our culture. It becomes a part of who we are. Many associate food from our childhood with warm feelings and good memories and it ties us to our families, holding a special and personal value for us. Food from our family often becomes the comfort food we seek as adults in times of frustration and stress.

    On a large scale, traditional food is an important part of culture. It also operates as an expression of culture identity. Immigrants bring it wherever they go, and it is a symbol of pride for their culture and means of coping with homesickness.

    Many immigrants open their own restaurants and serve traditional dishes. However, the food does not remain exactly the same. Some materials needed to make traditional dishes may not be readily available, so the taste and flavor can be different from what they would prepare in their home countries. Additionally, immigrants do not only sell dishes to people from the same countries as them, but to people from different countries. Therefore, they have to make small changes about the original dishes to cater to a wider range of customers. Those changes can create new flavors that still keep the cultural significance of the dishes.

    We should embrace our heritage（传统）through our culture's food but also become more informed about other cultures by trying their food. It is important to remember that each dish has a special place in the culture to which it belongs, and is special to those who prepare it. Food is a window into culture, and it should be treated as such.
