题目内容

Before leaving work, Steve Lee likes to use his cell phone to turn on his heat and air condition system at home. So by the time he gets through traffic into his front door, the temperature inside is perfect. You may wonder what a so-called smart home can do inside.

Lee works for a company called Smarthome. com, testing and living with many of his company’s home automation gadgets(自动化小配件), like this multifunction touch screen that controls devices around the house and even connects to the Internet traffic cameras.

“I have cameras, and they follow all the way down the freeway to work, ”said Lee with pride, “What’s going on at home when you are away? No problem, install some wireless cameras and controllers and from any computer in the world with an Internet connection, you can watch your house. ”

“You can check on the house, and I can look at the temperature. Believe it or not, if I want to turn on lights ahead of time, I can, ”added Lee.

We sat in Steve’s California kitchen and with the right password, turned on the kitchen counter lights at his boss’ house in Wisconsin. Steve did have permission to log on(登录).

“If you do know the password and you want to play a trick on your wife, you could turn lights on and off remotely. ”

This new technology, which can automatically turn on water sprinklers when humidity is low, or turn off a pool pump when it is not in use, is no longer expensive. Several hundred dollars for a basic system is enough and it is not hard to install.

Sure the convenience is nice but many people who like the security advantages like making sure kids are safe with the help of camera monitors and bedside alerts.

“I can notice that maybe one of my children wakes up in the middle of the night once the light switch is turned on. ”

What a smart home can’t do is get you a snack and you have to leave the couch for that.

People typically wash their hands seven times a day in the United States, but they do it at a far higher temperature than is necessary to kill germs (病菌) , a new study says. The energy waste is equivalent to the fuel use of a small country.

Amanda R. Carrico, a research assistant professor at the Vanderbilt Institute for Energy and Environment in Tennessee, told National Geographic that hand washing is often “a case where people act in ways that they think are in their best interest, but they in fact have inaccurate beliefs or outdated perceptions.”

Carrico said, “It’s certainly true that heat kills bacteria, but if you were going to use hot water to kill them it would have to be way too hot for you to tolerate.”

Carrico said that after a review of the scientific literature, her team found “no evidence that using hot water that a person could stand would have any benefit in killing bacteria.” Even water as cold as 40°F (4.4°C) appeared to reduce bacteria as well as hotter water, if hands were scrubbed, rinsed（冲洗）and dried properly.

Using hot water to wash hands is therefore unnecessary, as well as wasteful, Carrico said, particularly when it comes to the environment. According to her research, people use warm or hot water 64 percent of the time when they wash their hands. Using that number, Carrico’s team calculated a significant impact on the planet.

“Although the choice of water temperature during a single hand wash may appear unimportant, when multiplied by the nearly 800 billion hand washes performed by Americans each year, this practice results in more than 6 million metric tons of CO2 equivalent emissions annually,” she said.

The researchers published their results in the July 2013 issue of International Journal of Consumer Studies. They recommended washing with water that is at a “comfortable” temperature, which they noted may be warmer in cold months and cooler in hot ones.

B. It’s important for people to wash their hands to keep healthy.

C. Generally, people’s hand washing behaviors and perceptions are not correct.

D. People like washing their hands very much.

A. using hot water to wash hands has a bad influence on our planet.

B. air pollution has become more and more serious.

C. using hot water to wash hands is a waste of energy.
