People typically wash their hands seven times...

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case where people act in ways that they think are in their best interest, but they in fact have inaccurate beliefs or outdated perceptions.”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.

1. What’s the meaning of what Carrico told National Geographic in the second paragraph?

A. People are more concerned about their health and begin to wash their hands.

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.

2.The figures in the sixth paragraph are used to show that __________.

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.

D. people should pay more attention to the environment around us.

3. This passage is organized in the pattern of __________.

A. fact and opinion

B. cause and effect

C. definition and classification

D. time and events

4.What can we learn from the passage?

A. It’s necessary and useful for people to wash their hands frequently every day.

B. We can wash our hands with water that is at a “comfortable” temperature.

C. Using cold water to wash hands is necessary and much healthier.

D. Hot water can’t kill germs.

They may seem like ordinary people by day but in their spare time, these office, shop and school workers bring history to life. During the week they work in shops, offices, clinics and schools, but at weekends they transform into Vikings, Romans and Medieval peasants. The world of re-enactment (重演) is booming with more and more men and women taking up the hobby of travelling to bygone times.

Factory manager of a busy printers, Brett Freeman, 46, from Nottingham, changes into “Padmore,” a Victorian street-seller selling stationery (文具).

Already a veteran (老兵) of military re-enactments, Brett joined the “Ragged Victorians” when middle-age kicked in. “I was too old to portray a soldier but I wanted to get back into the hobby and the Ragged Victorians looked the best in terms of being genuine.”

At his first event, group members gave him “loaner gear” and a year to research his character. His teeth blackened with theatrical stain, in top hat and floppy coat, Brett looks every bit his Victorian image.

Seeking inspiration, Brett dipped into the works of Victorian journalist, Henry Mayhew, who wrote about the working people of London.

“My character is inspired by the description of a stationer in Mayhew’s London Labour and London Poor. I mixed that up with my own background in print, and local historical sources to create street stationer, Padmore, which is the name of my Victorian great-great grandfather.”

“Getting into kit (装备) helps immensely and once you are in the public area you try to remain in character wherever possible.” For extra authenticity, Brett combines his language with Victorian selling patter (顺口溜), replacing the word “envelope” with “hangflups.”

“Re-enacting is great fun, but we’re always glad of a hot shower and a comfortable bed at the end of the weekend,” says Brett. “Normal life can seem very dull after a particularly good weekend. It would be wonderful to go back in time for a visit, but studying the period as I have done, makes you realise just how hard life was for our ancestors.”

1.Why does Brett choose to be a Victorian street-seller?

A.He has already played a veteran.

B.Portraying a soldier no longer fit him.

C.He is a manager of a busy printers.

D.His blackened teeth make it real.

2.What does the underlined phrase “loaner gear” in paragraph 4 mean?

A.Stage costume lent to him. B.Money paid on loan.

C.Adequate time. D.An assistant.

3.Which of the following words can best describe Brett?

A.Brave and careful. B.Kind and positive.

C.Humorous and caring. D.Serious and devoted.

4.Where can you probably find the above passage?

A.In a research report. B.In a magazine.

C.In a travel brochure. D.In an advertisement.
