题型：不详难度：来源：
So who can really benefit from an online program? Well, anybody, and everybody! Online programs can turn out to be a pocket-friendly choice to a traditional college for many people. Here’s a list of people who usually consider joining in an online degree program;
l Stay-at-home parents. Online education is perfect choice for stay-at-home parents and those who have very young kids. Online classes give them the flexibility to complete or further their education while looking after home and family and without worrying about childcare.
l Working professionals who want to further their education but travel a lot or have extremely busy schedules, as well as those who want to make a career change but do not have the time to enroll in a full-time degree program.
l People who cannot commute(乘车上下班)to a college campus.
l Shy students who might feel embarrassed among a group of people and prefer to study by themselves and at their own pace.
l People who want to save money. Online programs can turn out to be more cost-effective than attending a physical classroom.
l People who do not get distracted (分心的)easily — something many people overlook when considering online education. If you are someone who can easily ignore the ringing of a phone, stay away from TV, and resist all other things that may draw your attention, online programs are for you.

A microscope is a useful instrument for observing small objects. By producing a bigger image, the microscope reveals details that are undetectable to the naked eye(裸眼).
Before using the microscope, please read the instructions below.
CAUTION: Microscopes are both delicate and expensive and must be handled with care.
1. Always carry the microscope with two hands — one supporting the base and the other on the arm.
2. Avoid stretching the wire of the lamp across a walkway.
3. Keep the stage clean and always use a glass slide for specimens(样本).
4. To avoid crushing the glass slide when focusing, begin with the lens close to the specimen and gradually back off to focus.
5. Keep the microscope covered to prevent the dust while it is being stored.
HOW TO USE THE MICROSCOPE:
1. Plug(接通电源) in the lamp.
2. Place a sample of what you wish to observe on a slide.
3. Adjust the mirror so it reflects light from the room up into the objective lens. When the mirror is correctly adjusted, a complete circle of light iwll appear when you look through the eyepiece.
4. Place your slide with the specimen directly over the center of the glass circle on teh stage. If it is a wet slide, be sure the bottom of the slide is dry.
5. With the LOW POWER objective leans placed over the slide, use the coarse focus knob to lower the lens to the lowest point.
6. Look through the eyepiece with one eye while closing the other eye. Slowly raise the lens until teh focus is relatively clear.
7. Use the fine focus knob to fine -tune(微调)the focus.
8. Without changing the focus knobs, switch to the HIGH POWER objective lens. Once you have switched to HIGH POWER, use only the fine focus knob to make the image sharper.
小题1:Which of the following is the correct way to use a microscope according to the text?
| A．Use one hand to carry the microscope |
| B．Place a sample directly on the clean stage |
| C．When stored, the microscope should be adjusted. |
| D．Look through the eyepiece with one eye. |
| A．Switch to objective lens. | B．Adjust the mirror. |
| C．Look through the eyepiece. | D．Place the hair on a glass slide. |
| A．after correctly adjusting the mirror |
| B．while looking at the specimen on a glass slide |
| C．after slowly raising the objective lens |
| D．before positioning the mirror correctly |
Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus.
The Verichip is about the size of a grain of rice and works using radio frequency identification technology. At a shop, a radio frequency “reader” would send a signal and the chip in your arm would respond with your unique identity number. That would give the “reader” your financial information, and money could be taken directly from your accounts and you wouldn"t even have to reach for your wallet.
The company also hopes to include other information on the chip, such as medical records, building security codes(密码) and passwords, making life even easier.
But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake(假的) reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go.
And if you wanted to get rid of your chip,you would need an operation to remove it.
小题1:The Verichip is .
| A．the identity number | B．the security code |
| C．a tiny microchip | D．a radio reader |
| A．how the Verichip works |
| B．the importance of the Verichip |
| C．the development of the Verichip |
| D．how money is taken from your accounts |
| A．Your information on it will always be safe. |
| B．Medical records have already been included. |
| C．You can easily reach for your wallet using it. |
| D．An operation has to be performed to remove it. |
| A．All people are satisfied with the chip. |
| B．The Verichip company has financial problems. |
| C．The chip needs improving to be widely accepted. |
| D．Many people have the experience of losing keys or money. |
| A．warn | B．advertise | C．compare | D．introduce |
Whenever anyone measures educational success, East Asian countries are always top scorers. But in a recent league table, a European country, Finland, was top of the class. South Korea was still in second place, though. Britain was at number 6.
In Korea the school day is long—typically 7 or 8 hours, followed by hours of private tutoring in the evenings. All this hothousing leaves Korean students so tired, they sometimes fall asleep in class next day. Worries about the effects of late night cramming(填鸭式) led the government to force cramming schools to close by 10 pm. Finnish children spend the least time in class in the developed world, often finishing just after lunch, with about one hour of homework a day. Private tuition is uncommon. The British and American school day is quite long in comparison, around 6 hours, and secondary school pupils do 2 or 3 hours of self-study a night.
The Korean education system, like many in Asia, is intensely competitive, with students even competing to get into the best cramming schools, to help them get ahead. Finnish education is far less cut-throat. Classes are all mixed ability, and there are no league tables. British schools again occupy the middle ground, with quite high levels of competition for places at university, and schools and universities battling to come top of league tables for everything from exam results to student satisfaction. Korea and Finland both do well, yet their education systems are so different.
However, there are some similarities in Korea and Finland. In those countries, teachers have high status in society, and education is very highly valued. Those attitudes can"t change quickly. But it can be done. They might be the star pupils now, but until the l970s, Finland"s educational system was poor. Their thoroughly different approach to schooling has taken them to the top in just a generation.

| C．long-hour study | D．school study |
| A．Finnish students are less stressed in study |
| B．there"re also many cramming schools in Britain |
| C．students in Korea are the most competitive in Asia |
| D．British schools are less competitive than universities |

Since the 1960s, the United States and a handful of other countries have trained dolphins and sea lions to detect sea mines and swimmers, to recover inert torpedoes（鱼雷）and to test objects used in Naval exercises.
Program officials estimate that the sea lions in the Marine Mammal Program have recovered millions of dollars of U.S. Naval torpedoes and instrumentation dropped on the sea floor.
The U.S. Navy kept its Marine Mammal Program a secret until the 1990s, and this spring CNN became one of only a handful of media outlets to see firsthand how the program works.
The program has trained about 75 Pacific bottlenose dolphins, with natural biosonar (生物声纳) that tracks better than any manmade device; and 35 California sea lions, with superb underwater eyesight.
Not only do these trained marine mammals track and retrieve millions of dollars in U. S. military equipment, they are also helping to save lives.
The Navy won"t disclose whether the dolphins and sea lions have effectively intercepted （阻拦）terrorists attempting to do harm to any U.S. facilities.
"Either way, it serves as a deterrent（阻碍） effect." says Christian Harris, operations supervisor for the program. The mammals can be deployed（调动） via C-130 cargo aircraft to perform their missions anywhere in the world within 72 hours. They have been used in exercises from Alaska to Hawaii, operating in great temperature and environmental ranges. They also have the capability to operate off vessels.
Dolphins most recently were deployed in the Iraq war, performing mine detection and clearance operations in the Persian Gulf to ensure safe passage for humanitarian ships delivering aid. Some of these Iraq war "veterans" are now back home, tasked with a new mission: guarding nuclear submarines in their homeports of Bremerton, Washington, and Groton, Connecticut.
小题1:The underlined word "retrieve" in Paragraph 6 can be replaced by ________.
| A．find out | B．recover | C．save | D．detect |
| A．To detect sea mines and swimmers. |
| B．To save lives of people. |
| C．To recover inert torpedoes. |
| D．To help the U.S. Naval test equipment. |
| A．These trained marine mammals eat pounds of fish a day. |
| B．The U.S. Navy performed the Marine Mammal Program for about 30 years secretly. |
| C．These mammals can carry out a task everywhere. |
| D．A lot of countries will train dolphins and sea lions for anti-terrorism. |
| A．The Special Skills of Marine Mammals | B．The U.S. Anti-terrorism Program |
| C．Exceptional Anti-terrorism Member | D．Trained Marine Mammals |
of its 200 inhabited islands，which are spread across an area of"35，000 square miles，99 are good resorts(旅游胜地)．So many tourists come every year，more than double the local population．Of these，over l 00，000 travel from the U K．The capital，Mal6，is four times more densely populated than London．Given these facts，it’S hardly surprising that the Maldives has a waste disposal problem．
