In a strange example of “art inspires life”,the self?drying jacket that Marty McFly wore in the movie,Back to the Future Ⅱ,has actually become a reality. A model has already been created and a Kickstarter campaign plans to raise funds for mass production.

The jackets,named SDJ?01,are classified as wearable tech,because of the inner air circulation(环流;循环) system that speeds the drying process from the inside out. Under normal circumstances,you can expect the jacket to dry in about 1-2 minutes after being exposed to rain or a spilled drink. If you jump into a pond to escape danger,it will probably take longer.

“Think of how quickly your clothes dry when you turn a standard fan on them. Now imagine how quickly breathable(透气的),water resistant(抗……的) material dries when exposed to concentrated,high?pressure air. In lab tests,our jacket consistently experienced noticeable drying effects after just 30 seconds,with the average time of about a minute to achieve a 90% drying effect,” explained Aaron Coleman,lead designer at Falyon Wearable Tech,which is producing the jacket.

“This is something that has been on my mind for years,” he said. He didn’t want it to be just a movie prop,but an actual usable jacket. “We wanted to follow the basic design of the jacket from the movie Back to the Future Ⅱ but update it a bit,adding more pockets for all the things people carry around these days.”

Eventually,Coleman and his team hit upon the perfect combination of water resistant material and high?pressure air circulation to achieve complete drying in just one minute. The outer layer is made of water resistant nylon,with insulation(绝缘材料) made of polyester fibre on the inside. It dries itself through a couple of so?called “air amplifiers(放大器)” attached to the sides,which force more air through the jacket.

According to the makers,the SDJ?01 is ideal for rainy days and spills,and the fans are perfect to cool off on days “when you’re just a little too warm,but it’s too cold to take off your jacket”.

1.How long does the SDJ?01 take to achieve a 90% drying effect,on average?

A. About 30 seconds.

B. About a minute.

C. About 1-2 minutes.

D. Longer than 2 minutes.

2.According to Aaron Coleman,in what way is the design different,compared with the jacket in Back to the Future Ⅱ?

A. The number of pockets.

B. The function of pockets.

C. The colour of pockets.

D. The shape of pockets.

3.What is the main achievement by Coleman and his team in developing the SDJ?01?

A. The noticeable drying effects of high pressure air on wet clothes.

B. The inner air circulation system can speed the drying process from the outside.

C. The perfect combination of water resistant material and high?pressure air circulation.

D. The various functions of water resistant materials during rainy days and spills.

4.What is the main idea of the passage?

A. The ideal design of a self?drying jacket.

B. Marketing strategies for a self?drying jacket.

C. The development of a self?drying jacket.

D. A basic introduction to a self?drying jacket.

Our environment isn't as green and beautiful as it should be.There are steel monsters blocking out the sun. blowing out dangerous smoke,and letting out poisonous chemicals into rivers,cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet.Facing current environmental problems,people need to do their best to save the earth.

You cart see many big garbage dustbins in the streets.They're not there for a show,but for you to drop your waste.We should realize that what we do does count.So next time you get that urge to throw gum or a chocolate package out of the car window,or "accidentally" drop as you walk down the street,ask yourself how much waste you've been contributing to the environment with that bad habit going on for years.

At home,the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps are not leaky(漏的),which would help greatly in scrimping.Another is to use energy-saving lights,and turn them off before you leave the rooms.It is not only energy-saving,but also cuts down electricity costs.

Recycling is a method to make items reusable.Many things you want to throw out can be made into new products through the reproducing process.Use your imagination to come up with ways on things that you can use again.

Pass the message of simple ways to save the environment on to kids.Starting with kids is a good way of teaching the message early in their lives,in the hope that they can carry it forward as they grow older.

With environmental protection awareness in mind,we can do what we can,for the results are to have a big effect on the planet.As long as we do our part,the world is one small step closer to being saved.

1.In the first paragraph the author uses "steel monsters" to refer to .

A. big factories B. high mountains

A. To protect the environment may help you save some money.

B. Your bad habits for the environment are a harmful contribution.

C. The more people do their part,the greener the environment will be.

D. Selling what you don't want any more is not a kind of recycling.

You drive down the highway with your family or friends in the car,camping equipment and spare clothes in the back.Your windows are down and the wind is hitting you in the face.These are the makings of a classic US road trip.

Road trips are quite common in the country,especially during the Thanks-giving holiday,which is the busiest travel time of the year in the country for families and friends who want to get together.

And for students,going on a road trip is traditional after graduating from high school or college with their schoolmates.It usually involves traveling great distances across the US and camping out whenever possible. Destinations are different depending on where in the country someone is located.But they all show the same kind of adventure.Popular spots to travel to include Yellowstone National Park,the Grand Canon.

However,the most famous of all road trip journey is travelling across the US on Route 66.Route 66 begins in Chicago and ends in Los Angeles.The route goes past many of the lesser-known states.However,it's the bizarre(稀奇古怪的)and wonderful small attractions that draw many road trippers to them.The attractions one sees on these trips are quite strange and very difficult to explain to non-American.They are filled with gas stations that still look like they did back in the 1950s and small restaurants known as "mom and pop restaurants" where you can eat a greasy cheeseburger with a delicious milkshake.Route 66 is also filled with quite unusual,but still fascinating wonders.

Deep down,US road trips show the spirit of freedom and openness.The idea is that if you have a car,you have freedom to escape,to discover,to find yourself,to lose yourself.It's a powerful call,one that is part of the US' identity and culture.It is a must-do for anyone who plans to spend time in the US to see the country and all of its wonders.An old saying—"It's not the destination,it's the journey"—best explains what the experience of a road trip truly offers.

1.The first paragraph is designed to .

A. present the topic B. list some facts

C. raise a question D. give an example

2.What attracts US road trippers most on Route 66?

A. Lesser-known states.

B. Mom and pop restaurants.

C. Gas stations and delicious foods.

D. Strange attractions and fantastic wonders.

3.What is the author's purpose in writing the text?

A. To introduce US road trips.

B. To spread American culture.

C. To stress the importance of a road trip.

D. To attract US road trippers to Route 66.
