Today, enjoy the highlights of Shanghai, China's most {#blank#}1{#/blank#}(energy) city consisting of people from different parts of the world. Your tour will begin with a tour of Old Shanghai, a {#blank#}2{#/blank#}(mix) of pretty narrow streets, traditional Chinese stores, and restaurants selling delicious dumplings, {#blank#}3{#/blank#} is the original pre-war Shanghai. Dating back to 1911 Shanghai, Old Town, was a walled city made up {#blank#}4{#/blank#}(main)of fishermen, but the walls of the city {#blank#}5{#/blank#}(tear) down to allow free movement and easier trade. Continue through the Old Town, {#blank#}6{#/blank#}you'll find the Yu Garden there, first {#blank#}7{#/blank#}(establish) in the Ming Dynasty by a Mandarin named Pan Yunduan, who used to be the governor of Sichuan. The Yu Garden is considered {#blank#}8{#/blank#}the best garden in Southeast China, and enjoys {#blank#}9{#/blank#}history of over 400 years long. A large-scale restoration of the Yu Garden was conducted {#blank#}10{#/blank#}it opened to the public formally in 1961.

    Cambridge University is one of the {#blank#}1{#/blank#}(old) universities in the world, and one of the largest in the United Kingdom. It is famous {#blank#}2{#/blank#} outstanding academic achievements and the high quality of research undertaken in a wide range of science and art subjects. The university pioneers work in the {#blank#}3{#/blank#} (understand) of diseases, the creation of new materials, advances in telecommunications and the research into the origins of the universe. It trains doctors, veto, architects, engineers and teachers. At all levels about half of the students at Cambridge study arts and humanities, many of {#blank#}4{#/blank#} have gone on to become outstanding figures in the arts, print and broadcast {#blank#}5{#/blank#}(medium). The university's achievements in sconces can be measured by the sixty or more Nobel Prizes {#blank#}6{#/blank#}(award) to its members over the years.

    As Cambridge approached {#blank#}7{#/blank#}(it) eight hundredth anniversary in 2009, it was looking to the future. The modern university is an international center of teaching and research in {#blank#}8{#/blank#} vast range of subjects. It continues to change in response to the challenges it faces. The 1990s {#blank#}9{#/blank#}(see) a major expansion of the university accommodation for teaching and research. There are many major new buildings either underway {#blank#}10{#/blank#} already completed, including the Law Faculty Building and the Judge Institute of Management Studies.

    The choices people make can cause cancer. Not everyone who {#blank#}1{#/blank#} (use) tobacco products will get cancer, but the chance of getting certain{#blank#}2{#/blank#}(type) of cancer increases with tobacco use. The recent research{#blank#}3{#/blank#} (show) us that the constant misuse or overuse of alcohol may cause cancer of the mouth and throat as well recently.

    Sometimes cancer can be caused by radiation{#blank#}4{#/blank#} (find) in sunlight and X-rays, in addition {#blank#}5{#/blank#}other places. This doesn't mean you should stop getting X-rays or stay indoors, but limiting your{#blank#}6{#/blank#} (expose) to radiation can reduce the chances of developing cancer. The X-rays you get at{#blank#}7{#/blank#} doctor's or dentist's office are not {#blank#}8{#/blank#}(typical) enough to cause cancer.

    And sometimes, the reason{#blank#}9{#/blank#} someone gets cancer is simply an unfortunate mystery. Some cells in the body may start to increase and change. Doctors and researchers can see it happening{#blank#}10{#/blank#}they cannot provide a description of why it started.

    The following is just a short story but it really brought home to me how very small acts of kindness and even polite behavior have {#blank#}1{#/blank#} (big) effects than we realize.

    I have a bad back {#blank#}2{#/blank#} flares up (发作) from time to time. Yesterday I was out walking in the street while {#blank#}3{#/blank#} (carry) shopping bags and my keys. My keys {#blank#}4{#/blank#} (sudden) slipped from my hand and fell to the ground. The problem was that because of my back I couldn't bend down {#blank#}5{#/blank#} (get) them. I was just thinking of how to get around this {#blank#}6{#/blank#} two teenage girls came up beside me. Without even speaking to me, one of the {#blank#}7{#/blank#} (girl) just reached down, picked up my keys, handed them {#blank#}8{#/blank#}me and went on her way.

    While it was {#blank#}9{#/blank#} small gesture and she couldn't have known that I was in too much pain to bend down, it {#blank#}10{#/blank#} (mean) a great deal to me at that moment

    With the amazing development in China, all China's major cities have good transport networks. There are the tour buses, mini buses, taxis, as well as public buses.

    Buses in Chinese towns are always {#blank#}1{#/blank#} (crowd). The fare depends on distance, and is payable to the {#blank#}2{#/blank#} (conduct) of buses.

    A taxi is often {#blank#}3{#/blank#} most convenient means of travel in the city. They are available at airports, railway stations and hotels and even in urban areas. The total fare depends on the starting meter price, {#blank#}4{#/blank#} can range from 5 to 12 yuan, and the distance. Extra fees{#blank#}5{#/blank#} (charge) for waiting and low speed driving during traffic jams. If you take a taxi after 11 pm, a 20 percent surcharge {#blank#}6{#/blank#} (apply) over the basic fare.

    The minibus is a compromise between the {#blank#}7{#/blank#} (relative) expensive taxis and full public transport. Their charge is a little more than that of the bus, about 2 yuan or more {#blank#}8{#/blank#} (depend) on distance, but it is very convenient, because it can stop {#blank#}9{#/blank#} any point you want along the route.

    Tour buses, normally {#blank#}10{#/blank#} (equip) with air conditioning and TV, are managed by travel agencies, hotels and airports and provided for short tours. A tour guide is usually present on such buses.

    Senior citizens are the first to come to our mind when you think of hearing loss, but in a recent report, hearing professionals worry teenagers will soon outnumber aging adults {#blank#}1{#/blank#} it comes to living with hearing loss.

    The rise in popularity of personal audio devices from iPods to smart phones has had dangerous effect on the ears of those who use them most, teenagers! A research {#blank#}2{#/blank#} (conduct) by the World Health Organization finds that nearly 50% of teens {#blank#}3{#/blank#} (fall) into the habit of exposing themselves to unsafe levels of sound so far.

    A sound is considered unsafe when it goes beyond 85 decibels (分贝). At that level, it takes just 8 hours of listening over your lifetime to cause damage. The louder the sound is, the {#blank#}4{#/blank#} (little) time it takes to cause damage. Because hearing loss is {#blank#}5{#/blank#} (typical) considered a health problem for the elderly, it is difficult to convince already stubborn teenagers that they really are doing damage {#blank#}6{#/blank#} their ears.

    Young adults {#blank#}7{#/blank#} have been exposed to loud noise over a period of time may have some hearing loss symptoms. Their {#blank#}8{#/blank#} (able) to learn is compromised, and they may have difficulty developing social skills.

    In an effort to help teens better protect their hearing, we suggest {#blank#}9{#/blank#} (set) volume limits on personal audio devices. {#blank#}10{#/blank#} is also good to limit the amount of time exposed to noise and to take listening breaks to give the ears a rest.
