                                                                                          500 Days of Summer

    Tom is in love with Summer from the moment he sees her. Can he accept that she simply likes him for now, not for forever The movie is about Tom wrestling with that reality. Tom remembers his love, Summer, as a series of joys and bafflements (疑惑). But Summer is just herself and he cannot have her.

    Here is a rare movie that begins by telling us how it will end and is about how the hero has no idea why.

2012

The director Roland Emmerich successfully dresses an old story with an old Mayan prediction, which is believed by many to happen in the coming 2012 and as a result, attracts millions of people into the cinema.

    It's just an entertaining Hollywood blockbuster （大片）with plenty of jokes, instead of a description of what the end of the world is really like. Don't take it too seriously!

    Alexis, 17, sat quietly in the passenger seat of her dad's car. She let her eyes lazily scan the landscape for wildlife. Then a deer came into view about 200 yards in front of them. “Dad, there's a deer there!” Alexis said. It was a male deer with sharp antlers (角) on each side of its head.

    As the car moved closer, Alexis saw that the deer's head was bent toward the ground. Then she heard a scream and saw an arm fly up near the deer's head. Alexis realized the deer was attacking a woman. Sue, a 44-year-old mother, had been out for her morning run. The deer followed her and edged closer. “I knew I was in trouble.” Sue says. She went to pick up a stick for self-defense, and the deer charged. It lifted her with its antlers and threw her into the air. Sue could feel blood flew down her leg. Within seconds, the deer had pushed her off the road.

    When Alexis and her father pulled up, the deer was throwing Sue like a doll. Alexis looked into the woman's terrified eyes, and before her father had even stopped the car, the teenager jumped quickly out of the car and ran toward the deer. “I was kicking it to get its attention." she says. Then her father, who had followed his daughter, pushed the deer away from the women.

    Alexis helped Sue into the car and then applied a piece of cloth to Sue's injured leg. “We're going to get you to a hospital.” Alexis said. Then she heard her father shout loudly. He had been knocked to the ground. Alexis took hold of a hammer from the car and ran to where her father lay on his back. She beat the deer's head and neck, but the blows didn't scare it away. “I was losing faith.” she says. “A couple more strikes. Alexis.” said her father. “You can do it.”

    Turning the hammer around, Alexis closed her eyes and beat the deer's neck with all her strength. When she opened her eyes, the deer was running away.

    Alexis got in the driver's seat and sped toward the nearest hospital. After Sue was treated, she tearfully thanked her rescuers. “You expect a teenage girl to get on the phone and call for help,” she says, “not to beat up a deer.”

    Driving a car is not just handling controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant (抑制药),damaging eyesight, judgment and co­ordination(协调),slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.

    Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.

    The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is： 50 milligrams of alcohol per 100 ml of blood； or 22 micrograms of alcohol per 100 ml of breath; or 67 milligrams of alcohol per 100 ml of urine (尿液)．

    Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.

    Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK $ 25000 and be sentenced to up to 3 years in prison and punished for 10 driving­offence points; or temporarily banned from driving.

    The same punishment applies to failing to provide specimens (样本)for breath, blood or urine tests without good excuse.

    Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.

    It happens from time to time: you feel terrible when you take your first bite of a certain food, but after eating more, you find yourself enjoying it. This is what is called an acquired taste. But why do our tastes change?

    The answer, according to a recent study presented at an American Chemical Society meeting in Boston, lies in proteins in our saliva (唾液).

    Most of us tend to think saliva, almost entirely made up of water, is “only a mouth lubricant (润滑剂) helping us to swallow food,” the New York Times said. However, it also contains many proteins, which can help break food down, protect our teeth and help in tasting food.

    To explain how these proteins affect taste, a team of scientists from Purdue University in the US invited 64 volunteers to drink a bitter-tasting chocolate milk three times a day for six weeks and rated their tastes at the same time.

    According to the research, the participants found a strong bitterness on the first day, but the unpleasant flavor came to decrease as time went on and finally disappeared.

    That is not all that was changing. A noticeable increase in the levels of proline-rich (富含脯氨酸的) proteins was found in the saliva samples of the test subjects in the research period. These proteins serve to reduce the bitterness we taste and improve our adaptation to this flavor.

    “We think the body adapts to reduce the negative feeling of these bitter compounds,” said Cordelia Running, a food scientist at Purdue University. “Saliva changes flavor, which in turn changes eating choices.”

    This change in taste not only makes the food tastier, but also helps people keep an appetite for healthy food whose flavor might otherwise keep them away.

    One day, these proteins may even be extracted (提炼) and used as a separate food additive that could help people stick to healthy food whose flavor they continue to dislike, researchers told Science Alert. And according to Running, even it doesn't happen, the idea that “maybe some little piece of your body is actually trying to help you” could really benefit some people. Let's wait and see.

    Teenagers who talk on the cell phone a lot, and hold their phones up to their right ears, score worse on one type of memory test. That's the finding of a new study. That memory impairment might be one side effect of the radiation (放射线) that phones use to keep us connected while we're on the go.

    Nearly 700 Swiss teens took part in a test of figural memory. This type helps us remember abstract (抽象的) symbols and shapes, explains Milena Foerster. The teens took memory tests twice, one year apart. Each time, they had one minute to remember 13 pairs of abstract shapes. Then they were shown one item from each pair and asked to match it with one of the five choices. The study volunteers also took a test of verbal memory. That's the ability to remember words. The two memory tests are part of an intelligence test. The researchers also surveyed the teens on how they use cell phones. And they got call records from phone companies. The researchers used those records to figure out how long the teens were using their phones. This allowed the researchers to work out how big a radiation exposure (接触) each person could have got while talking.

    A phone user's exposure to the radiation can differ widely. Some teens talk on their phones more than others. People also hold their phones differently. If the phone is close to the ear, more radiation may enter the body, Foerster notes. Even the type of network signal that a phone uses can matter. Much of Switzerland was using an older "second-generation" type of cell phone networks, the study reports. Many phone carriers (通讯公司) have moved away from such networks. And more companies plan to update their networks within the next few years.

    The teens' scores in the figural memory tests were roughly the same from one year to the next. But those who normally held their phones near the right ears, and who were also exposed to higher levels of radiation, scored a little bit worse after a year. No group of teens showed big changes on the verbal memory test. Why might one type of memory be linked to cell phone use, but not another? Foerster thinks it could have to do with where different memory centers sit in the brain. The site that deals with the ability to remember shapes is near the right ear.
