    Each year，half a million people die from brain aneurysms(动脉瘤)—when a blood vessel bursts in the brain.An aneurysm is a bulge in a blood vessel that can burst.If that happens in the brain，it can be deadly.For survivors，physical disabilities are often severe.They may include memory problems，loss of balance，trouble speaking and even blindness.But new technologies are increasing survival rates and reducing disabilities.

    Beaumont Bacon is a survivor who makes light of her experience because she is a comedian.She uses humor to make others laugh.Now she's working on a new show.Michael Alexander is her doctor.He operated on Beaumont Bacon after her attack.“She had bleeding in the frontal area of her brain，so right above the eyes.The part that was in the brain was about maybe the size of an egg.So，that's a fairly large bleed.”

    Ms.Bacon had a better chance at survival than most people because of Dr.Alexander.He directs the Neurovascular Center in Los Angeles.The center offers new technologies that include placing a catheter(导管) into an aneurysm，then threading wires to promote blood clots(血栓)．This technique reduces the chances of another burst blood vessel.“You don't have to open up the skull or open up the brain to do surgery.It's all done from inside the blood vessels.So it reduces the amount of blood loss，and the recovery is much faster.”

    For Beaumont Bacon's recovery，the hospital worked to prevent problems commonly found in patients with a burst aneurysm.The problems include brain swelling that can shut down blood vessels.She spent a month in a coma(昏迷)—unable to communicate with doctors，friends and loved ones.But with a year of treatment，she recovered.Now，she is making people laugh.

                                                                      Little－known facts about germs

    Germs are everywhere and in so many forms. There are some steps you can take to help prevent the spread of germs in your personal space.

    Computer keyboards can have more germs than a public toilet.Keys and spaces on a keyboard are main breeding grounds for bacterial and viral growth. Clean your keyboard regularly with specialized wipes for electronics，and remove dust with an air duster.

     While it seems to make sense that covering your toothbrush would protect，the opposite is the case.With a cover on your brush，a more humid environment is created and more likely to encourage growth of germs.Wash your toothbrush when done，and allow it to air dry.Make sure you store it away from the toilet.

    Hand sanitizer(洗手液) does not always replace soap and water washing.Hand sanitizer is great when you're not near a sink，and need to clean your hands.But given the choice of a spritz of sanitizer or good old soap and water，choose the soap and water route.  Lather up and scrub hard for at least 20 seconds，and wash between your fingers and the back of your hands.Don't skimp with the hand sanitizer either—cover the same hand areas as for soap and water.

     If you freeze foods that you suspect might be spoiled，freezing them will not kill the germs already in the food.Freezing prevents further bacterial growth，but when you thaw it out，the bacteria continue to increase and pollute your food.

A．Freezing food does not kill germs.

B．Try not to eat outside especially in summer.

C．Exposure to germs can lead to many illnesses.

D．Toothbrush covers do not protect your brushes from bacteria.

E．There are a lot of effective ways to get rid of germs in your house.

F．Soap and water are only a better germ fighter when done properly.

G．Some reports show five times more germs on a keyboard than on a public toilet.

    A survey has shown that what you do on a plane can be determined by which nationality is listed on your passport.

    According to the results of an international passenger survey, Australians are the biggest drinkers on board with 36 percent choosing to down the hatch, compared to 35 percent of Americans and 33 percent of Brits.

    The Airline Passenger Experience Association(APEX) spoke to around 1,500 people, aged 18 and older, who have travelled by plane at least once during the last three months and were living in the United States, United Kingdom, Germany, Japan, China, Singapore, Australia and Brazil.

The results found Chinese travelers are most likely to nod off once the seat-belt sign switches off. They are also the first to take out their credit card for some in-flight shopping and the biggest fans of gaming. Americans on the other hand like to use their time in the air more productively—- when not drinking—- choosing to work while flying at 35,000 feet.

Meanwhile, Brits and Germans are the best at making chat with random strangers—-spending 50 percent more time than any other nationality. Comparatively, Brazilians conduct their conversations online via email, messaging apps or social media.

    Despite plane food having a bad reputation, seven out of ten interviewees said they were happy to eat up on the selection of in-flight snacks and meals. In-flight magazines were also popular with four out of five passengers.

    The international flyers did however express their desire for better in-flight entertainment. “The industry has greatly improved the comfort, entertainment and onboard service, and passengers are accepting those improvements” said Russell Lemieux, APEX executive director. “At the same time, passengers are demanding more from their air travel experiences which will drive more improvements touching all aspects of the journey. ” he added.

    A recent announcement by scientists that they have successfully cloned the first human embryo(胚胎) has caused much debate and has shocked many people around the world. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable tissues(组织) and organs that could be used to save human lives. On the other hand, many people, including some scientists, disagree and fear that if mankind interferes with (干涉) nature in this way, they may be on their way to producing a real-life Frankenstein's monster.

Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly—the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were angry because they thought cloning would create more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific breakthrough.

    The Scottish scientist who created Dolly, Ian Wilmut, is shocked that some scientists are now considering cloning human beings. Although he researches cloning, he has never thought of creating copies of humans. Instead, he thinks the scientists should concentrate on creating new tissues and organs that could eventually be used to cure diseases like cancer. However, some people consider that cloning human embryos with the intention of destroying them shows no respect for human lives.

    While cloning human embryos is illegal in many countries, some scientists are already pushing ahead with the research so as to deliver a cloned human baby. Severino Antinori, an Italian doctor, is one of the leaders in this field of research. He has declared that he wants to be the first to clone a human being.

In China, scientists have focused their efforts on cloning animals, as well as stem cells to be used in medical research. China has succeeded in producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.

“Nature does not hurry, yet everything is accomplished.”—Lao Tzu

If you are in a city where everyone rushes, realize that you don't have to be like everyone else. You can be different. You can walk instead of driving in rush hour traffic. You can be on your iPhone or Blackberry less, and disconnected sometimes. Your environment doesn't control your life—you do. I'm not going to tell you how to give you a step-by-step guide to moving slower.

    ⒈Do less.

Cut back on your projects, on your task list, on how much you try to do each day. Pick 2-3 important things— or even just one important thing— and work on those first. Save smaller, routine tasks for later in the day, but give yourself time to focus.

    ⒉Meeting are usually a “big waste of time”. And they eat into your day, forcing you to squeeze the things you really need to do into small windows, and making you rush.

    ⒊Start to put off or cancel the unnecessary.

    When you do the important things with focus, without rush, there will be things that get pushed back, and that don't get done. And you need to ask yourself:What would happen if I stopped doing them?

    ⒋Practice mindfulness.

    Don't care so much about future or the past. When you eat, fully appreciate your food. When you are with someone, be with them fully. When you are walking, appreciate your surroundings, no matter where you are.

    Try these things out. Life is better when unrushed. Remember the quote: if nature can get everything done without rushing, so can you.

A. Have fewer meetings.

B. How necessary are these things?

C. Simply learn to live in the present.

D. Focus not on quantity but on quality

E. Give yourself more time to get ready and get there.

F. The world likely won't end if you don't pass one of the examinations.

G. But here are some things to consider and perhaps adopt, if they work for your life.
