Most schools ban chewing gum, but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help boost your test scores.
This exciting research is just beginning. And at the same time, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath.
These gums are part of the growing number of foods and drinks that contain health-boosting ingredients. If you're already a gum fan, that's probably welcome news.
Americans chew about 1.8 pounds of gum per person each year, according to the U.S. Census Bureau. By showing that gum chewing can be healthy, companies that make and sell gum hope that we'll chew even more.
Chewing gum might be good for your brain. One Japanese study of nine participants found that chewing gum boosted the flow of blood to participants' brains by up to 40 percent. Blood carries oxygen, which fuels brain cells.
Other small studies have found that people perform better on memory tests while chewing gum. And a study in the United Kingdom found that people who chewed gum while memorizing a list of words did about 25 percent better at recalling those words than people who didn't chew gum.
But additional studies are still needed to confirm that chewing gum has benefits. So far, results of studies about memory have been mixed. Not all tests have had similarly encouraging results. What's more, many of the studies that show gum's benefits are funded by gum companies.
So, for now, chew with caution. Too much chewing can damage the jaw joint. And chewing too much of a gum that contains vitamins, caffeine, or a medicine could lead to an overdose. What's more, no matter how healthy gum chewing proves to be, it will never be a match for a healthy lifestyle. Nothing like a gum or a vitamin is going to cure a bad eating habit or a bad exercise habit. It's not a magic bullet. Scientific studies about gum chewing show that ______.

We observe today not a victory of party but a celebration of freedom, symbolizing an end as well as a beginning, signifying renewal as well as change for I have sworn before you and Almighty God the same solemn oath our forbears (ancestors) prescribed nearly a century and three-quarters ago.
The world is very different now, for man holds in his mortal hands the power to abolish all forms of human poverty and all forms of human life. And yet the same revolutionary beliefs for which our forbears fought are still at issue around the globe, the belief that the rights of man come not from the generosity of the state but from the hand of God. We dare not forget today that we are the heirs（继承人）of that first revolution.
Let the word go forth from this time and place, to friend and foe (enemy) alike, that the torch has been passed to a new generation of Americans born in this century, tempered by war, disciplined by a hard and bitter peace, proud of our ancient heritage and unwilling to disciplined by a hard and bitter peace, proud of our ancient heritage and unwilling to disciplined by a hard and bitter peace, proud of our ancient heritage and unwilling to witness or permit the slow undoing of those human rights to which this nation has always been committed, and to which we are committed today at home and around the world.
Let every nation know whether it wishes us well or ill that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, to assure the survival and the success of liberty. This much we pledge (promise solemny) and more.
In the long history of the world, only a few generations have been granted the role of defending freedom in its hour of maximum danger. I do not shrink from this responsibility. I welcome it. I do not believe that any of us would exchange places with any other people or any other generation. The energy, the faith, the devotion which we bring to this endeavor will light our country and all who serve it and the glow from that fire can truly light the world.
And so, my fellow Americans ask not what your country can do for you; ask what you can do for your country. My fellow citizens of the world ask not what America will do for you, but what together we can do for the Freedom of Man.
Finally, whether you are citizens of America or citizens of the world, ask of us here the same high standards of strength and sacrifice which we ask of you. With a good conscience our only sure reward, with history the final judge of our deeds, let us go forth to lead the land we love, asking His blessing and His help, but knowing that here on earth God’s work must truly be our own.What should friends and foes know?
| A．That the United States is powerful. |
| B．That a new generation of Americans are responsible for their government. |
| C．That the United States is governed by liberals. |
| D．The rights of man come from the hand of God. |
What is Kennedy’s promise to the world?
| A．To support liberty. |
| B．To abolish all forms of human poverty. |
| C．To visit each country at least once. |
| D．To support and friend. |
What should citizens of the world ask of America?
| A．How America can help them. |
| B．If America plans to invade their country. |

| B．We should remember we are the first revolution. |
| C．Our nation has always been committed to human rights. |
| D．We should assure the survival and the success of liberty. |

How did a ban on smoking in public places come into place?
In 1998 the Smoking Kills White Paper set out a national strategy (策略) to reduce smoking prevalence (流行) and passive smoking, including in public places. The measures were voluntary and poorly carried out. After a public conference in England in 2004, the Government decided to choose for lawmaking. Scotland went first, with a ban in 2006, followed by the other nations a year later.
What is the current law?
Any person who smokes in enclosed (封闭的) public places, including pubs, offices, on public transport and work vehicles, is breaking the law. It does not extend to private houses. It is also an offence for people in charge of premises (营业场所) to permit others to smoke in them.
How was it received?
It was welcomed by most organizations except for some pub owners and restaurateurs. Many workplaces in the UK had already introduced smoke-free policies consistent with the legislation (法律，法规) before it was carried out, while others have gone beyond its basic requirements.
All railway facilities, including platforms, footbridges and other areas--whether or not fitting the definition of an enclosed public space--are covered, as are all football grounds and some cricket and athletics stadiums. School grounds are not required to be smoke-free under the legislation, but the majority now are.
How has it been forced?
Compliance (服从) in public premises has been high, with inspections suggesting that 99 per cent of places were sticking to the rules. The number of people charged for smoking in cars has been very low, which was due to the problems defining and identifying "work" vehicles. They said that a total ban on smoking in vehicles would end this confusion.
Has it improved health?
Studies in early adopters of the law, including in Scotland, suggest a reduction in hospital admissions for heart disease, which has been shown to be linked to passive smoking. There is also strong evidence of improved rates of smoking end and a drop in the number of cigarettes consumed by those who continue to smoke. When did the first law come out to ban smoking in public places?
| A．1987 | B．1998 | C．2004 | D．2006 |
Which of the following behaviors may NOT be against the law?
| A．Jack often smokes in the office when he is alone. |
| B．A taxi driver is smoking with a lady in his car. |
| C．Tom smokes while thinking of his future at home. |
| D．Max smokes for relaxation during time-out in the stadium. |
Who might feel unhappy about the law according to the article?
| A．A restaurant owner. | B．A company manager. |
| C．A car owner. | D．A policy maker. |
What can you infer from the article?
| A．Most heart diseases have been proved to be linked to passive smoking. |
| B．A new law will soon come out with a total ban on smoking in vehicles |
| C．Cigarette-making factories will disappear soon. |
| D．Most of the school grounds are not smoke-free, as it is not banned in the law. |
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 co-ordination (协调)，slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving link , 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 (浓度) is:
● 50 milligrams of alcohol per 100ml of blood ;or
● 22 micrograms of alcohol per 100ml of breath ;or
● 67 milligrams of alcohol per 100ml of urine(尿液)
Drivers who cause traffic accidents, or who commit a moving traffic offence(罪) or are being suspected of drink driving will be tested.
Any drive found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK﹩25,000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence 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.The first paragraph is mainly about_____________.
| A．the introductions of driving skills | B．the damage of drinking to your body |
| C．the effect of drinking on driving | D．the process of alcohol being absorbed |
The underlined word “it” in the second paragraph refers to “________”.

I have always loved kids. However, the children here at Shanti Bhavan are unlike any that I have ever met. They have a strong drive and determination and are thankful for the wonderful opportunity they have been given. While at Shanti Bhavan, I taught 3rd graders writing, language, and literature, 8th, 9th, and 10th graders public speaking, 9th and 10th graders basketball, and piano lessons. I found teaching the children was the most rewarding experience of my life. They are really fast learners and really have an interest in knowledge. It was easy to get on with such polite, well-mannered, and hard-working students. They dream big and I only hope that I can continue to be a part of helping them achieve their goals.
As far as my day-to-day living went, I was perfectly comfortable here and came to consider it as a second home. My room was clean and comfortable and the staff could not have been nicer.
In addition, I really appreciated the support of all the teachers. They were so welcoming and kind that it truly cleared away my fears and culture shock. They often gave me advice and befriended me and I owe much to them for their warmth.
I honestly feel that Shanti Bhavan is the most beautiful place on earth. It has love and learning, and I am very sad to be leaving. I am looking forward to my return to this newly found family as soon as possible. Thank you so much Miss Beena and Mrs. Law for all of your love and support.
