【题目】 The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic device such as portable computers, radio and cassette players and mobile telephones.

RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban such devices from being used during “critical” stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights.

The difficulty is predicting how electromagnetic fields might affect an aircraft’s computers. Experts know that portable device emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not.

The fact that aircraft may be vulnerable to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can’t hear the instructions to turn off his radio because the music’s too loud.

1The passage is mainly about _____.

A.a new regulation for an airlines

B.the drawbacks of electronic devices

C.a possible cause of aircraft incidents

D.effective safety measures for air flight

2What is said about the over 100 aircraft incidents in the past 15 years?

A.They may have been caused by the damage to the radio systems.

B.They may have taken place during take-off and landing.

C.They were proved to have been caused by the passengers’ portable computers.

D.They were suspected to have resulted from electromagnetic interference.

3Few airlines want to impose a total ban on their passengers using electronic devices because ______.

A.they don’t believe there is such a danger as radio interference

B.the harmful effect of electromagnetic interference is yet to be proved

C.most passengers refuse to take a plane which bans the use of radio and cassette players

D.they have other effective safety measures to fall back on

4It can be inferred from the passage that the author _____.

A.hasn’t expressed his own opinion on this problem

B.has overestimated the danger of electromagnetic interference

C.is in favor of prohibiting passengers’ use of electronic devices completely

D.regards it as unreasonable to exercise a total ban during flight

Chinese Herbal(草本的) Medicine

Genuine Chinese people have found thousands of plants and herbs associated with the 1treatof diseases, so herbal medicine is really 2large system. Doctors would analyze their nature or property such as “cold and hot” or “yin and yang”, use all sorts of raw 3material, and mix them to cure disease. Thus it is also different from the western medicine.

About the classification, in the Compendium(纲)of Material Medical by Li Shizhen in the Tang Dynasty 618-907, there are 1892 types 4record. Today we can 5briefdivide them into roots, rhizome(根茎), leaf, flower, seeds, grass, vines(藤蔓), and so on.

Of course these raw(生的) herbs cannot be eaten when put before you; they need your own hand to prepare. 6 patients take is decoction(煎汁)of the herbs.

The quality is concerned 7 the decocting jar, quantity of water, and the frequency of decoction. Doctors suggest that water amount 8controlaccording to the nature of absorbing. Because the herbs bought from the chemist’s are usually dry, most of 9 need to be immersed into the water for 1-3 hours before decocting. The effect after 2 or 3 times’ decoction is 10good than once. The mount patients will take is about 200-300 mi for children and 400-600 ml for adults.

【题目】 I once met a well-known botanist at a dinner party. I had never talked with a botanist before, and I found him very interesting. I sat there absorbed and listened while he spoke of unusual plants and his experiments (he even told me astonishing facts about the simple potato). I had a small indoor garden of my own—and he was good enough to tell me how to solve some of my problems.

As I said, we were at a dinner party. There must have been a dozen other guests, but I broke an important rule of politeness. I ignored everyone else and talked for hours to the botanist.

Midnight came. I said good night to everyone and departed. The botanist then turned to our host and said many nice things about me, including that I was a “most interesting conversationalist”.

An interesting conversationalist? I had said hardly anything at all. I couldn’t have said anything if I had wanted to without changing the subject, for I didn’t know any more about plants than I knew about sharks.

ButI had done this one thing; I had listened carefully. I listened because I was really interested. And he felt it. Naturally that pleased him. That kind of listening is one of the best ways to show respect to others, and it makes them feel great too. “Few human beings,” wrote Jack Woodford in Strangers in Love, “can resist the sweet effect of rapt attention.” I went even further than that. I was “sincere in my admiration and generous in my praise”. I told him that I had been hugely entertained and instructed. I told him I wished I had his knowledge. Itold him that I should love to wander the fields with him. What’s more, it was all true.

And so I had him thinking of me as a good conversationalist when, in reality, I had only been a good listener and had encouraged him to talk.
