高中英语人教版选修七Unit 3 Under the sea同步练习

阅读下列短文,从每题所给的四个选项 (A 、B 、C  和 D )中,选出最佳选项。

    The pillage (掠夺) and destruction of ancient shipwrecks and sunken archaeological sites by treasure hunters seeking gold and other valuables may be illegal under the terms of an international treaty under discussion by UNESCO's 188 Member States.

    "Protecting our underwater heritage is extremely important and increasingly urgent as no site or shipwreck is now out of bounds for treasure hunters. New technologies have made deep-water wrecks easily accessible and these technologies are getting cheaper," warns Lyndel Prott.

    According to estimates by commercial salvors (寻宝者), there are some three million undiscovered shipwrecks scattered across the world's oceans. Even the figures for the known wrecks are impressive. The Northern Shipwrecks Database for example contains 65,000 ship loss records for North America alone from 1500 AD to the present. The Dictionary of Disasters at Sea by Charles Hocking (1969) lists 12,542 sailing ships and war vessels lost between 1824 and 1962.

    Then there are sunken cities such as the trading town and pirate stronghold(海盗堡垒) of Port Royal in Jamaica, which disappeared beneath the waves after an earthquake in 1692. Or the remnants of ancient civilisations, such as the Lighthouse of Alexandria in Egypt, and the Neolithic villages being discovered under the Black Sea, which some believe could help explain Noah's great flood.

    These treasures of cultural heritage are under serious threat. Technology now allows extraordinary access to the ocean depths for determined and well-financed treasure hunters. And the potential rewards are huge. In 1985, American salvor Mel Fisher discovered the wreck of the Señora de Atocha, a Spanish ship that sank off the Florida Keys in 1622 with her cargo of gold, silver and jewellery worth an estimated US $400 million.

    An archaeologist can spend ten years or more studying a ship, conserving its objects and publishing its findings. We gain an enormous amount of information and knowledge from this work. With treasure hunters, all of this is lost. This is tragic, for humanity as a whole.

(1)、Why is it important and urgent to protect our underwater heritage?
A、Underwater heritage is easily accessible to treasure hunters. B、Underwater heritage is out of reach of archaeologists. C、New technology makes protection of underwater heritage easier. D、There is no law to protect underwater heritage.
(2)、What is the third paragraph mainly about?
A、Shipwrecks discovered by commercial salvors. B、The main cause of shipwrecks. C、The history of sunken ships. D、The figures of shipwrecks around the world.
(3)、What happened to Port Royal in 1692?
A、It was washed away by flood. B、It was beneath the waves after an earthquake. C、It was discovered under the Black Sea. D、It was rebuilt by Noah.
(4)、Why is Mel Fisher mentioned in the fifth paragraph?
A、He risked his life in treasure hunting. B、He was one of the most successful commercial salvors. C、He made a great discovery of shipwrecks. D、He had no trouble in finding a shipwreck.

    Jimmy is an automotive mechanic, but helost his job a few months ago. He has good heart, but always feared applyingfor a new job.

One day, he gathered up all his strengthand decided to attend a job interview. His appointment was at 10 am and it wasalready 8:30. While waiting for a bus to the office where he was supposed to beinterviewed, he saw an elderly man wildly kicking the tyre(轮胎) of hiscar. Obviously there was something wrong with the car. Jimmy immediately wentup to lend him a hand. When Jimmy finished working on the car, the old manasked him how much he should pay for the service. Jimmy said there was no needto pay him; he just helped someone in need, and he had to rush for aninterview. Then the old man said, “Well, I could take you to the office foryour interview. It's the least I could do. Please. I insist.” Jimmy agreed.

    Upon arrival, Jimmy found a long line ofapplications waiting to be interviewed. Jimmy still had some grease on himafter the car repair, but he did not have much time to wash it off or have achange of shirt. One by one, the applicants left the interviewer's office withdisappointed look on their faces. Finally his name was called. The interviewerwas sitting on a large chair facing the office window. Rocking the chair backand forth, he asked, “Do you really need to be interviewed?” Jimmy's heartsank. “With the way I look now, how could I possibly pass this interview?” hethought to himself.

    Then the interviewer turned the chairand to Jimmy's surprise, it was the old man he helped earlier in the morning.It turned out he was the General Manager of the company.

  “Sorry I had to keep you waiting, but Iwas pretty sure I made the right decision to have you as part of our workforcebefore you even stepped into the office. I just know you'd be a trustworthyworker. Congratulations!” Jimmy sat down and they shared a cup of well-deservedcoffee as he landed himself a new job.

    Our local Community Youth Club is a very popular organization with young people in my town. I have been a member for four years now and I've taken part in a lot of interesting projects. These include fun activities such as holiday camps and discos. We have organized sports competitions and we even made a video.

    But it isn't all just enjoyment, we have also started doing social work to help people in our neighbourhood. We have organized activities for small children during the holidays. We have also formed a social support group to help young people stop smoking.

    We are particularly proud of the most recent group we have created. It organizes regular visits to the local old people's home. This idea came from a school visit to an old people' home. My class spent an afternoon at a home and everyone found the visit very rewarding.

    The old people at the home were very excited by our visit. They were very talkative(健谈的) and they told us their personal stories. During our visit, the home was filled with the sound of laughter. We sang songs and played games with the old people and had tea together. But we realized that life wasn't always easy. Some of them were in poor health and were very unhappy. They couldn't go outside the visits by children brought some sunshine into their lives.

    Many young people like me do not live with our grandparents and we have very little contact with elderly people. As a result, many young people don't know what they are like and we have a lot of wrong ideas about them. We have little or no idea of the kind of lives they lead in their homes. After this visit, my friends and I decided we should do something to help improve the quality of their lives.

    Since the creation of our visiting group, over twenty volunteers(志愿者) have joined us. Up to now, we have organized three group evenings and a concert. But it is the individual(单独的) visits which are the most important. Club members regularly visit old people and everyone finds the experience rich and rewarding.

    A few years ago, bubble tea(奶茶) exploded as a popular drink for Internet foodies(吃货) everywhere. Many take this Taiwanese drink as a guilt-free snack similar to juice or a cup of coffee. After all, it has the word "tea" in it, so it has to be healthy…right?

    Not quite. Like coffee, bubble tea's ingredients(成分,配料) might not be so bad on their own, but when they're loaded with sweetener(甜味剂) and artificial flavor(人工香料), they lose their nutritional (营养的) value fast.

    It all starts with those "bubbles" found at the bottom of your drink, which are actually round pieces of tapioca(木薯淀粉). Called "tapioca pearls(珍珠)," they're actually made from a vegetable that grows in South America. And as it turns out, those little balls are loaded with sugar—and not the nutritious, fiber-rich(富含纤维) kinds found in whole grains(全麦类), either.

Cooking tapioca pearls only makes it worse. They're typically fried in hot water, along with even more added sugar, for up to three hours. By that point, these balls could have nearly 160 calories per ¼ cup.

    And don't even get us started on what comes in the extra syrups(糖浆). Thanks to all those processed(加工的) ingredients, the average bubble tea can easily reach 300 to 400 calories per cup!

    On top of being an unhealthy habit, bubble tea could even shorten your life. In 2012, a group of German researchers from the University Hospital Aachen reportedly found aspolychlorinated biphenyls, or PCBs, in tapioca ball samples. These cancer-causing chemicals have also been shown to have other bad effects on the immune(免疫), reproductive(生殖), and nervous systems.

    You might want to lay off your bubble tea addiction. Thankfully, we have a few choices for low-calorie, healthier drinks, instead.

    Planning a visit to the UK? Here we help with ways to cut your costs.

    AVOID BIG EVENTS     Big sporting events, concerts and exhibitions can increase the cost of accommodation and make it harder to find a room. A standard double room at the Thistle Brighton the final Friday of the Brighton Comedy Festival (19 Oct.) cost £169.15 at Booking.com. A week later, the same room cost £118.15.

    If you can be flexible and want to know dates to avoid -or you're looking for a big event to pass your time—check out sites such as Whatsonwhen.com, which allow you to search for events in the UK by city, date and category.

    STAY AWAY FROM THE STATION     If traveling to your destination by train, you may want to find a good base close to the station, but you could end up paying more for the sake of convenience at the start of your holiday.

    Don't be too choosy about the part of town you stay in. Booking two months in advance, the cheapest room at Travelodge's Central Euston hotel in London for Saturday 22 September was £95.95. A room just a tube journey away at its Covent Garden hotel was £75.75.And at Farringdon, a double room cost just £f62.95.

    LOOK AFTER YOURSELF     Really central hotels in cities such as London, Edinburgh and Cardiff can cost a fortune, especially at weekends and during big events. As an alternative consider checking into a self-catering flat with its own kitchen. Often these flats are hidden away on the top floors of city centre buildings. A great example is the historic O'Neill Flat on Edinburgh's Royal Mile, available for £420 for five days in late September, with room for four adults.
