高三英语单项填空简单题查看答案及解析

A new keyboard can tell whether you are its owner. The keyboard records information about the typing pattern and sends it to a computer program. The program then checks to see if the pattern matches the right user. If not, an alarm sounds, and the computer locks the typist out. It locks out anyone else, even if the person knows password. What’s more, this device needs no batteries. It harvests all the energy it needs from the action of your typing. Besides, the keyboard is also self-cleaning and the keys are free of damage from water, oil and dirt.

The keys of the new keyboard are made of the same inexpensive plastic that might be found on any other standard keyboard. But instead of being smooth, the keys have millions of tiny plastic nanowires（纳米线）on their surface area to every key, increasing the effective contact area between the plastics and fingers. This ensures that there's enough power to run the keyboard as someone types.

Liming Dai, a scientist, did not work on the new keyboard, but he thinks the design could be important in getting better performance from a variety of devices. “It could also be applied to a touch screen, for instance,” Dai says. “Then smart phones and notepads could harvest energy from the action of someone typing or drawing.”

“Future work might make the keyboard even more useful,” Dai adds. “A later design might build tiny capacitors（电容器）onto the nanowires,” he suggests. Capacitors are little devices that temporarily store electric charges. Those might then LEDs to light a Keyboard in the dark.

Zhonglin Wang is a co-designer of the new keyboard. His team has built a working model of the keyboard. “If a company decides to fund（投资）its production, this keyboard could be in stores in as little as two years,” says Wang.

1.How does the new keyboard tell whether you are its owner?

A. By matching the typing pattern to the right user.

B. By sending alarms to a computer program.

C. By checking the right user's passwords.

D. By recording information about the typing pattern.

2.Why are there many nanowires on the surface of the keys?

A. To increase the effective contact area.

B. To improve the speed of typing.

C. To make the keys smooth.

D. To help produce power.

3.What’s Dai’s attitude to the new keyboard?

A. Unconcerned.　　 B. Doubtful.

C. Positive.　　 D. Critical.

4.What is the best title for the text?

A. A New Keyboard Made of Nanowires

B. A New Keyboard Entirely Owned by you

C. A New Keyboard’s Future

D. A New Keyboard Powered by Typing

The earth is getting warmer. The planet is suffering. But what can you do about it? Reduce the amount of waste you generate. Use cleaner energy sources and go greener today, starting with these steps:

.1. Get a reusable water bottle

Americans buy about 25 billion single-serving plastic water bottles each year. That's an average of 83 bottles per person per year. Plastic bottles take plenty of resources to produce, including fuel for transportation and petroleum to make the plastic. Even recycling bottles uses energy.

.2. Eat less meat

You don't need to become a vegetarian to help save the planet. Eating meat just one day less a week can reduce your negative impact on the environment. More water, energy and land are required to produce meat than to produce grain.

.3. Switch to energy-efficient light bulbs

Most households use standard incandescent (白炽的) bulbs. But compact fluorescent (荧光的) light bulbs, or CFLs, use 66 percent less energy than standard bulbs, produce just as much light, last up to 10 times longer and don't need to be replaced as often. If every household in the United States replaced just one incandescent light bulb with a CFL bulb, it would equal removing one million cars from the road.

.4. Buy organic and local food

Did you know that only 1 percent of pesticides (杀虫剂) applied to crops reach the pests they target? The rest enter the environment. Organic food is grown without the use of pesticides. Organic farming can use 50 percent less energy than traditional farming methods. Buying local food saves on the fuel used to transport food grown elsewhere, thousands of miles across the country or around the world.

.5. Recycle your electronics

Everyone knows the importance of recycling glass and plastic, but what about cell phones, computers, CDs and batteries? Electronics are responsible for about 40 percent of toxic (有毒的) heavy metals such as lead and mercury. Check with your city's recycling facilities to see if they take electronics.

1.The readers of this passage are called on to ______.

A. help reduce global warming               B. use water in a wise way               C. donate money for charity                D. keep a balanced diet

2.What is an advantage of CFLs according to the passage?

A. They use more energy but produce more light.                                   B. They can last longer so don't need to be replaced often.                                         C. They cost less than standard incandescent bulbs.                                         D. They are as energy-efficient as incandescent bulbs.

3.Which of the following figures is correct according to the passage?

A. Every year an American buys 63 plastic water bottles on average.                   B. Eating meat one day less a week helps cut environment costs.                                   C. 99 of the pesticides used on crops is effective in practice.                                         D. Electronics account for half of poisonous heavy metals on the earth.

4.Which can be the best title for this passage?

A. Why is the earth getting warmer?     B. What can we do about pollution?            C. How can you lead a greener life?        D. Who is to blame for global warming?

You can tell a lot about a person from the clothes they wear, but you can also tell a lot about a person simply from the handbags they carry. It's hard to believe, but you can find out a number of things about a woman's personality just by looking at the type of handbag she carries. Below you will find a number of handbag styles and colors as well as what each specific type of handbag says about the owner.

Styles:

Under-the Shoulder – handbags which are smaller and fit tightly underneath the shoulder indicate class and sophistication. A women working in an upscale office or someone of high status would choose this form of handbag.

Big and Bulky – Big, bulky and oversized bags are casual and are often associated with younger individuals. These are used for individuals who carry a number of things (binders, books etc) and require a lot of space. Down-to-earth, lower-maintenance women would carry this type of handbag.

Designer – Designer handbags often cost an arm and a leg and therefore are usually associated with high-maintenance females. Females who are confident and require top of the line accessories will settle for nothing less than a name-brand designer purse. Guys watch out for these girls, they tend to be a handful.

Cigar Box Purses – A women who carries a cigar box purse likes to be unique and stand out from the crowd. These women have minds of their own and cannot be told what to do. They are comfortable in their own skin and tend to be very independent.

Leather with Buckles and Zippers – women who choose leather purses with lots of buckles and zippers are leashing out their wild sides. These women tend to act before they think and are always ready for a good time. The extra buckles and zippers tend to signify a "bad girl" image.

Colors:

Bright Colors – Bright colored handbags like pink, purple, bright blue and green indicate that the woman is fun, friendly and approachable. Women who are out-going and sociable will tend to choose these colors. This is the type of woman who will strike up a conversation with a complete stranger.

Black and Brown – women who choose black or brown handbags tend to be more formal in manners and are often mistaken as being snobby or restricted. These types of handbags are often associated with down-to-earth women, who are shy at first, but open up after a while. They tend to exude a shy confidence, which is sometimes mistaken as someone who thinks she's better than others.

The style and color of your handbag says a lot about you. Choose your handbag very carefully and remember you can choose more than one style. You may feel like being reserved one day and the center of attention another…it's natural to want different things in life.
