B
Language is always changing. In a society where life continues year after year with few changes, the language does not change, either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language About 3 percent of the people in the world speak languages that are not in these major families.

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increase the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.72. The underlined word “flaws” in the 2nd paragraph most probably means ______.
| A．evidence | B．facts | C．faults | D．failures |

The global energy crisis is approaching. What can we do? Here are some steps you can take.
Cooling puts the greatest stress on your summer energy bill and the power grid(电网). Just as t tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. Clean or replaces filters monthly or as needed.
For central air conditioning systems and room air conditioners, look for the ENERGY STAR, the federal government’s symbol for energy efficiency. For central air, purchase the system with the highest possible Seasonal Energy Efficiency Raton. (SEER)
Use energy-efficient ceiling fans either alone or with air conditioning. Ceiling fans do a great job of circulating air. When used with air conditioning, fans allow you to raise the thermostat(恒温器) and cut costs. Ceiling fans cool people, not rooms, so before you leave; turn off the ceiling fan.
Let a programmable thermostat! “remember for you” to automatically adjust the indoor climate with your daily and weekend patterns to reduce cooling bills by up to 10 percent. You can come home to a comfortable house without wasting energy and cresting pollution all day while you are at work.
Try to make your home airtight enough to increase your comfort, make your home quieter and cleaner and reduce your cooling costs up to 20 percent.
Gut your air conditioning load, and reduce pollution by planting planting leafy trees around your home and fixing reflective bricks on your roof.
Close blinds or shades on south-and west-facing windows during the day, or fix shading equipment to avoid heat build-up.
Turn off everything not in use: lights, TVs, computers. And use fluorescent bulbs(荧光灯), which provide bright, warm light while using at least two-thirds less energy, producing 70 percent less heat and lasting up to 10 times longer than incandescent bulbs(白炽灯).
Drive the car that gets better gas mileage whenever possible if you own more than one vehicle. If you drive 12,500 miles a year, switching 10 percent of your trips from a car that gets 20 mils per gallon to one that gets 30 mpg will save you more than ￡65 per year.
Carpool. The average U.S. commuter(乘车上班族) could save about ￡260 a year by sharing cars twice a week with two people in a car that gets 20.1 mpg---assuming the three passengers share the cost of gas.According to the passage, the thermostat is used to ______.
