Could a CD player, a laptop computer or a hand-held video game send an airline off course? Unless you are born with feathers, flying requires faith. Passengers have to believe, once on board the plane, that a 201800kg machine moving extremely fast in the air is firmly in the pilot’s control. That faith was shaken last week by a report that a DC-10 plane coming into New York’s Kennedy airport recently almost crashed(撞毁) when a passenger in the first class turned on his portable compact disc player.

The story, first published in Time Magazine, set off people’s concern. Can airplanes really be made to change their courses by something as small as a battery-powered CD player? Or a video-game machine? Or any of a dozen electronic gadgets(小器具) and computers that passengers regularly carry on board?

Although it may sound impossible, it can’t be ruled out. Every electrical device creates a certain amount of radiation. Portable phones, remote-control toys and other radio transmitters send out signals that can carry for kilometers, and their use on planes has long been cassette players, tape recorders and laptop computers, which make far less electromagnetic(电磁的) noise.

Now there is increasing proof that even these gadgets may be putting aircraft at risk. A walkman-type radio tuned to an FM station produces oscillations(振荡) that can reach 1.5m to 3.5m-far enough, in some planes, to reach the navigation(导航) equipment in and around the cockpit (驾驶员座舱).

No planes have crashed and no lives have been lost so far. But Time Magazine has got quite a few pilot reports linking a series of “anomalies”(异例) to a wide variety of electronic gadgets, from laptop computers to Nintendo Game Boys. In one striking example, a plane flying out of Chicago started going off course while its VOR dials became unclear and danced around. When the passenger in seat 9-D turned off his laptop, the report states, the “panel lights immediately brightened and all navigation aids returned to normal.”

The U.S. Federal Aviation Administration, pressed by pilots to punish the gadget holders on board, published an advisory late last week that Delta Airlines has already made longer its list of forbidden devices to include video playback machines and CD players.

With the arrival of new “fly-by-wire” aircraft, which are heavily computerized and even more easily to be interfered with, passengers may have to go back to reading paperbacks and watching the in-flight movies.

25. The purpose of this article is to inform the readers of______.

A. the risks connected with flying modern computerized planes

B. the conditions connected with taking off and landing in modern planes

C. the risks connected with using electronic devices while flying in modern planes D. the conditions connected with sitting within 3.5m off the cockpit in a modern plane 26. The following are four points made in the article, Which is the right order of what happened?

27. Which one of the following statements is true according to the information presented?

A. Remote-control toys are likely to produce radiation.

B. A DC-10 almost crashed while taking off from Chicago airport.

C. Walkman radios give off signals that can carry for several kilometers. D. The greatest risk to DC-10 planes comes from electromagnetic interference.

28. According to the U.S. Federal Aviation Administration, the best advice to offer someone who was

about to travel on a plane would be______.

A. don’t use any electronic devices while your plane is in the air

B. make sure that you are 3.5m from the cockpit before using electronic devices C. tune into AM radio stations while using your walkman if the plane is in the air D. check on whether the electronic devices you plan to take on board have been forbidden

Tea vs Coffee

Tea and coffee are two of the most widely consumed drinks in the United States. With popularity and interest in tea continuing to grow in recent years, many consumers have recently considered making the switch from coffee to tea, if they have not done so already. All the buzz surrounding tea and coffee may have you wondering, what are the differences? As it turns out, the differences are many and varied.

In the US, interest in tea ranges from coast to coast with the highest in Hawaii and California

but stretching to the eastern states of Vermont and New York. On the other hand, the highest interest in coffee tends to be concentrated more in the north and western regions(地区), with the highest search volumes appearing in the states of Hawaii, Washington and Minnesota.

Differences between tea and coffee also vary in origin and production. All tea comes from the harvested leaves of the Camellia sinensis plant, while there are about 60 different species of coffee plants. Production of tea is quicker and more efficient: Camellia sinensis plants only need to grow for three years before they are ready to process; coffee plants take up to five years.

Perhaps the most concerning issue consumers have when considering making the switch to tea is the question of caffeine. The good news is, when it comes to tea and caffeine, there is something for everyone. Unlike coffee, which typically only comes in decaffeinated and regular, there are several varieties of tea available, based on caffeine preference.

From herbal teas that are naturally free of caffeine, to high quality green and black teas that offer less than half the caffeine of coffee, to high caffeine teas such as our specially formulated HiCAF? blends that contain slightly more caffeine than a cup of coffee, there is a variety sure to suit your needs. As an added bonus, the lower acidity levels in tea tend to be gentler on the stomach for a more comforting pick-me-up.

So what is the answer, coffee or tea? If you are looking for the most healthful benefit possible, tea is probably the winner. They say a picture is worth a thousand words.
