Write NO MORE THAN THREE WORDS for each answer.
Not all print dictionaries are the same, as you will notice when you select one. To make a wise selection, you should know how to distinguish among three kinds of print dictionaries: pocket, desk, and unabridged. You should also know the copyright date of your dictionary, and check is special features.
A pocket dictionary is small. Generally, it contains no more than 75000 entries, making it hardly to carry to class and efficient to use. However, a pocket dictionary doesn't contain enough entries to be adequate for college reference homework. In addition, the information about each word in a pocket dictionary is generally limited. A desk dictionary is medium sized, generally containing over 100,000 entries as well as extra features. For college work, you should own a current desk dictionary. An unabridged dictionary is a complete dictionary. Abridged dictionaries, such as pocket and desk dictionaries, are shortened. Because unabridged dictionaries contain nearly all English words, they are large and heavy. They are often used by schools and libraries.
If the copyright date of your current dictionary shows that it was published five or more years ago, consider investing in a more recent edition. English is a dynamic language that admits new words and recognizes changes in meaning, spelling, and usage of familiar words. This is reflected in an up-to-date dictionary.
In selecting a dictionary, check the features it offers besides vocabulary definitions. Many editions contain signs, symbols and foreign words. Some also contain CD-ROMs and access to special online features.

The 2014 Nobel Prize in physics went to three scientists who gave lighting a big change by inventing blue LED lights. A big change in lighting efficiency is under way around the world.
Save and green
LEDs use less energy than other forms of lighting. A typical LED bulb(灯泡) can produce around 83 lumens per watt — a measure of how much brightness you can get from a unit of electrical power — much more efficient than other lighting facilities.
LEDs produce light by passing electric current through a semiconductor, while traditional bulbs pass current through a wire. The wasted heat energy is chiefly why traditional bulbs are so much less efficient.
LEDs also last about 30 times longer than traditional bulbs, and many LED bulb products promise up to 25,000 hours of use — more than 17 years if you used one for about four hours a day.
Lighting the world
The lighting application is not only in homes. LEDs are also being used for street lights, public holiday and decorative displays, commercial buildings, and other large energy users.
Car lighting is another application where LEDs are making progress. LEDs used to be used only for daytime running lights, but now many new cars have LED headlights for night-time use.
LEDs also hold promise for bringing light to the more than 1.5 billion people around the world without access to electricity, the Royal Swedish Academy of Sciences noted. Indeed, several proposed solutions to energy poverty include the distribution of LED lights, particularly solar-powered ones.
Digital displays
Without blue LEDs, the world wouldn’t have back-lit smart phones, TV and computer LCD screens, blu-ray(蓝光) players, many forms of lighting, and countless other products.
In the electronics industry, LEDs provide back lighting for the liquid crystal displays (LCDs) in many smart phones, laptops, and televisions. The LEDs are more energy efficient and allow for very thin displays.
Blu-ray players use blue LED lasers(激光) to read data off a digital optical disc. When these systems switched from using an infrared(红外线) laser to a blue LED laser, it became possible to store five to 10 times as much data.
LEDs are now being explored for their potential to transmit(传送) data from the Internet across open space, similar to WiFi. Such a system could transmit a lot more data than WiFi alone. This high bandwidth is possible because LEDs can turn on and off millions of times per second.
The rise of LED lighting came at a time when people were just starting to be concerned about global warming. Because of LEDs’ energy efficiency, using them for the world’s lighting would have “an extreme impact” on society.

Unlike in our country, violence against women is very obvious in some western and African countries. The basic cause of it lies in discrimination, which claims women inequality with men in all aspects of life. Violence is both origin in discrimination and serves to worsen discrimination.
Violence against women is a sign of historically unequal status of women compared to men, which has resulted into domination (控制,主宰) and discrimination against women by men and to the prevention of the full development of women. Violence against women is one of the important social means by which women are restricted into a secondary position in comparison with men.
As violence against women is spread worldwide, many women are targets because of their ethnic group, class, sex or disability status.
Many women think that the psychological consequences of abuse are even more dangerous than its physical effects. The experience of abuse often shakes women's self-respect and puts them at great risk of a number of mental health problems, such as:
Depression is becoming broadly recognized as a main health problem in the world.
Women who are abused by their partners suffer more depression and anxiety than women who have not been abused, according to studies in Australia, Nicaragua, Pakistan, and the US.
Post-traumatic stress disorder (PTSD) is a strong anxiety disorder that can happen when people go through or witness a very unpleasant event in which they feel disappointed and helpless or fear death or injury. The symptoms of PTSD contain mentally reliving the upsetting event by means of flashbacks (闪回,倒叙) ; avoiding anything that would remind one of the events; experiencing discomfort in sleeping and concentrating; and being easily alarmed or frightened.
The severe violence is also likely to lead to suicide. Some women kill themselves or try to do so. Researches from some countries, including Sweden, and the US, have showed that domestic violence is closely connected with suicide. Abused women who have PTSD symptoms prove to be most likely to try suicide.
Abused women are more likely than other women to misuse alcohol and drugs.
When a person' s everyday life functioning or life alternatives continue to be influenced, a post-traumatic stress disorder may be the problem, requiring professional treatment.

Bike riding is a great way to get exercise and fresh air. But before you rush out and start biking, tis an important thing you need to consider—safety.
Always wear a helmet when riding a bike, no matter ________ you are or how short the ride is. It can protect your brain from ghurt in a bike accident. Many bike accidents mean brain damage or death for someone who does not wearwhile riding. To protect against brain injury, make sure that the belts aref. What you wear when riding a bike is also very important for safety. Bright-colored clothes will help you be visible on the road. (除外) that, you have to choose good shoes. You should never ride barefoot!
Stop at all stop signs and otraffic lights just as cars do. Always stop and check for traffic in both (方向) when leaving a driveway.
Never wear ear-phones while biking. It’s important to hear everyone（其他）on the road.
One of the best ways for parents to help kids learn safe bike riding is to set anby following the rules of the road themselves.

Simply said, Bora Bora is the most beautiful island in the world. Pora Pora ----the ancient name, meaning “first born”, came from legends describing this as the first island to rise. Although the first letter “B” does not exist in the Tahitian language, when Captain Cook first heard the name he mistook the softened sound of “P” for “B” and called the island Bora Bora.
Bora Bora often reminds people of images of a heaven on earth. For this reason, travelling to Bora Bora is popular with honeymooners and anyone who wishes to be surrounded by amazing beauty. Bora Bora is a destination that is small enough to explore in a few days. However, because of the island’s friendly people and fun activities, you might be willing to extend your plan of Bora Bora journey for weeks.
The landscape consists of a mountainous centre that is completely surrounded by a lagoon(环礁湖，濒海湖)，which is then surrounded by a coral reef. These natural features make Bora Bora perfect for diving. The central feature of Bora Bora is Mount Otemanu, a huge rock that stands 2,379 feet tall.
Your Bora Bora vacations won’t be complete if you don’t visit the beaches and lagoons. Perhaps one of the best known features of Bora Bora is its white sand beaches. The most popular beach is Point Matira, located at the southern end of the island. The beach stretches for over two miles and is lined with palm trees.
There is more to do on Bora Bora vacations than lie on the beach. Hiking is an activity that Bora Bora’s 7,000 residents as well as Bora Bora travel enthusiasts, enjoy. If you’re up for a challenge, take the route from Vaitape to the top of Mount Otemanu. If you’re an inexperienced hiker, you might need the help of a guide.
