If you see someone drowning, speed is very important. Once you get him out of water, if he isn't breathing, you have four minutes before his brain is completely destroyed. Support his neck, tilt his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth breathing. Press his nostrils together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until help arrives. To bring a child back to life, keep your lips around his mouth and nose and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue-gray color1, and you can feel no pulse,then pressing is the last chance of saving his life. With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too hard or you may break a rib. Check how effective you are by watching if his color1 improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until help arrives. Which of the following statements is TRUE according to the passage? A) If a drowning man can't breathe again in four minutes, his brain will be completely destroyed. B) If you see someone drowning, you must give him mouth-to -mouth breathing. C) When you bring a drowning child back to life, you should give him as many breaths as possible. D) When pressing, you can do it as hard as you can.

When I worked as a waitress in Chicago, US, my coworkers and I would sigh whenever we heard someone with a foreign accent coming into our restaurant. We knew what it meant to serve a non-American: no tip. We would work just as hard as we always did, but we might not get paid. Americans have an unspoken rule about tipping: they give tips to almost everyone who offers them a service of some kind. Americans tip their waiters, barbers and taxi drivers. An appropriate tip is between 15 and 20 percent of the amount charged for the service (But the charge for the tip doesn't appear on the bill. The customer is expected to add it himself/herself.) Tipping less than this sends a message to your waiters that you think they've done a bad job serving you. And to leave no tip at all is simply unacceptable. It's not that American waiters are greedy. In many countries, waiters are paid a salary for their work. They'll earn money even if no one comes into the restaurant. This system offers much more safety for waiters than the American version. In the US, waiters know that a night without customers means a night without pay. Some countries include a tip for waiters - a "service charge" - on the bill itself. Since the tip is included with the other charges, waiters don't need to worry about people forgetting to tip. But in the US, waiters do not receive a salary, and service charges only appear on bills when there are six or more customers at the table. Since almost all American customers are familiar with the system, they know to add a tip without being told. But visitors to the US may expect waiters to be paid a salary, or think that the tip is included on the bill. So much as we waiters loved hearing stories about other places from our foreign customers, we were always nervous when they got ready to leave the restaurant. We were never sure what to expect. What is the main purpose of the passage? A) To complain about the difficult life of American waiters. B) To warn other waiters not to serve any foreign customer. C) To call on foreign customers to leave tips for American waiters. D) To tell us something about American waiters' salary system.

Q: Henry found work in a bookstore after he finished middle school. He wouldn't do anything but wanted to get rich. Mr. King thought he was too lazy and was going to send him away. Henry was afraid and had to work hard. It was a cold morning. It was snowing and there was thin ice on the streets. Few people went to buy the books and the young man had nothing to do. He hated to read, so he watched the traffic. Suddenly he saw a bag fall off a truck and it landed by the other side of the street. "It must be full of expensive things," Henry said to himself.

For those who are tired doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(application). Strange though it may seem -- "my wife already does that" was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week -- Samsung is just one of many appliance makers racing to install a large number of internet-connected features in machines in an effort to make them "smart". Last year, it was a refrigerator that tweeted. This year, it's Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad. The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owners is at work or on the bus. Samsung says it's not just something new -- the app connection actually has some practical uses. "If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go," said spokesperson Amy Schmidt. The company also says that with electricity rate varying depending on the time of day, more control over when the machines are used can help save money. Perhaps, but what they will probably really accomplish is what all good technologies do --enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV. What can be inferred from the common response of the attendees at the CES? A) The machine will be a big success. B) their wives like doing the laundry. C) The machine is unrelated to their life. D) This kind of technology is familiar to them.
