Directions: Read the following text and choose the most suitable heading from A—F for each paragraph. There is one extra heading which you do not need.
| A. Forecasting Research B. Well-known Weather Forecasters C. Severe Weather Events D. Weather Forecasting E. The Forecasting Process F. Historical Background |
The task of predicting the weather that will be observed at a future time is called weather forecasting. As one of the primary objectives of the science of meteorology, weather forecasting has depended critically on the scientific and technological advances in meteorology that have taken place since the latter half of the 19th century.
【小题2】
Throughout most of history, forecasting efforts at any given site depended solely on observations that could be made at the site. With the development of the telegraph in the mid-1800s, weather forecasters were able to obtain observations from many distant locations within a few hours of the collection of such data. Weather forecasting was revolutionized in the 1920s by the work of a group of Norwegian scientists. This group provided a consistent and empirically based description of atmospheric circulation systems. Current weather-forecasting techniques were initiated by the theoretical work of American meteorologist Jule Charney in developing numerical weather prediction. Experimental numerical forecasts in 1950 proved so fruitful that they were soon adopted on a practical basis. Since then, computerized systems based on numerical models have become a central part of weather forecasting.
【小题3】
The process of making a weather forecast can be separated into three steps: observation and analysis, extrapolation to find the future state of the atmosphere, and prediction of particular variables. The standard extrapolation technique is to assume that weather features will continue to move as they have been moving. In some cases the third step simply consists of noting the results of extrapolation, but actual prediction usually involves considerable efforts beyond this.
【小题4】
Great attention is paid to weather forecasts during times of severe events (blizzard, hurricane and typhoon, tornado), and so forth. Accordingly, the National Weather Service (NWS) commits significant resources to the forecast of such events. Blizzards or strong extra-tropical cycles are handled through the usual forecast information channels, with the local NWS office issuing special advisories as appropriate.
【小题5】
A number of new observing systems are being developed for forecasting purposes. These include the Next-Generation Radar digital weather radar, which is intended to detect motions towards or away from the radar installation. In addition, automated systems are being developed for taking observations at surface stations and on board buoys, ships, and aircraft. The communications, processing, and display systems intended to govern this torrent of further data are still being elaborated. 查看习题详情和答案>>
One morning Mrs Smith was driving home after she had done shopping. When she drove near a rubbish dump, she noticed a microwave oven(微波炉) not far from the side of the road.“John is a good electrician!”she said to herself.“Perhaps he can repair this. I'll take it home and let him try.”She picked up the oven and put it in the boot of her car. Then she drove on happily. A few kilometers later, she heard the siren (警报器)of a police car behind her. She looked in the driving mirror and saw a policeman waving to her to tell her to pull over and stop.
Mrs Smith was very puzzled. She slowed down at the side of the road. A traffic policeman got out of the police car and walked up to her.
“Can I see your driving license and insurance certificate(保险证)，please? ”he asked her. He copied down details of her name, address and the number of the car.“What's wrong, officer?” Mrs Smith asked. The policeman did not reply. He looked in the car and then at the back. “Open the boot, please.”he said to Mrs Smith.
Mrs Smith was still puzzled. She opened the boot and pointed to the microwave oven. "I found this old microwave oven a few minutes ago," she said. "I'm just taking it home to see if my husband can repair it." The policeman stared at her for a moment to see if she was telling the truth. "That's not a microwave oven." he said at last. "That's our radar set(雷达装置). It was the start of a speed trap. Do you mind if we have it back?" Mrs Smith's face turned red. "Oh", she said," I'm very sorry. I wouldn't have touched it if I'd known what it was."

Last year, I was speaking at a gathering of wealthy male investors. The organizers posted the 1 of a survey showing that only a small percentage of wealthy men believed their wives spent too much.
'What?' 2 one participant. 'Those guys have to be lying.'
There is no reliable 3 of who spends more among the rich: men or women. Both will say the other is the 4 spender.
A recent survey by Wilmington Trust, Campden Research and Relative Solutions proves the 5 . The companies polled 40 women (I know, that is more like a show of hands than 'survey'), each with a net worth of $25 million or more.
About half the respondents（受调查者） inherited（.继承） their 6 , a quarter 7 it from their husbands and the other quarter earned it 8 . That is roughly in line with other surveys of 9 women and the source of their money. One interesting note: among the self-made women, 90% got their money from owning a business, rather than 10 a salary.
As for 11 , almost all the women (90%) described their spending habits as 'below their means.' The report on the survey said that is 'possibly 12 they do not view their extreme wealth as defining their success.
'Women tend not to spend as much as 13 and splash（泼洒得使到处是） their names all over the place,' said one woman in the survey, describing her spending as conservative and he lifestyle as 'below the radar.'
Many women also worried about wealth having 14 effects on their children and didn't want to spend lavishly（挥霍） to 15 a bad example.
At the same time, 70% of the women said they 'buy nice things when 16 .' And 93.5% of the women said they were responsible for making 17 on major purchases, which 18 that they do a lot of the big spending.
Of course, for truly major purchases a house in Aspen, Colo., a Gulfstream, a Feadship the couple probably makes the decision 19 .
But what about other 20 ? Do you think men or women do most of the high-end spending?
( ) 1. A. results B. reasons C. times D. directions

查看习题详情和答案>>“People are ruder today because they are rushed and more ‘time poor’ than ever before, ” says Patsy Rowe, “ Manners have fallen off the radar(雷达). ” Due to our strong attraction to electronic equipment it is a wonder more people don’t wake up each morning and greet the singing birds with a complaint（抱怨）about the noise. Here are some examples of rudeness.
Some people prefer to do almost everything over the internet. To them, dealing with an actual human is like an evolutionary step backward. It feels very slow because humans don, t work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life-changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous（匿名的） rude messages by email.
However, rudeness is never acceptable, Don, t assume it is OK to be rude if the person you, re in touch with won, t recognize you. If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it. Upsetting people with unsigned messages is cruel and disgusting.
We shouldn′t blame technology for our shortcomings. Technology is here to help us, but we should not allow it to take over our lives. An important step is acknowledging our shortcomings. People spend a lot of time pointing out bad manners but it would be even more help if we′d publicly acknowledge good manners when we see them.
1.What can be inferred from the underlined sentence in Paragraph I?
A．People can tell good from bad behavior.
B．Radar is able to observe human behavior.
C．People care little about their behavior.
D．Radar can be used to predict human behavior.
2.Some people are less willing to deal with humans because
A．they are becoming less patient
B．they are growing too independent
C．they have to handle many important messages
D．they have to follow an evolutionary step backward.
3.The author thinks sending unsigned awful messages is
A．Ridiculous B．disgusting C．acceptable D．reasonable
4.What can we learn from the last paragraph?
A．We should applaud good behabior.
B．Technology can neber be blamed
C．We should keep pointing out mistakes.
D．Technology will take over lives one day.
