But they thought 16 . My complaints, repeating myself, even self-justified shouting were landing on 17 ears. I
9、 felt frustrated (沮丧的) , and very often a whole afternoons scolding would end with their 18 into tears, I realized I needed to 19 my methods of “mothering”. One day while they were at school, I had great fun 20 their rooms. On their desks, in plain 21 , I left the cards: “Dear Bill (the other card w
10、as 22 to Sarah), your room was messy this morning and Im sure you like it clean. Love, the House Fairy.” 23 arriving back, the children were 24 excited to receive the little note from the House Fairy. The next day, their rooms were fairly tidy. Sure enough, there was another note from the House Fair

Sometimes the House Fairy would propose a little 29 : “If you can finish your homework today and 30 it befo
12、re dinner, I d like to watch a particular television program with you tonight.” Sometimes some colored markers or other little items would be left in 31of jobs especially well done the day 32 . 33 I cant remember how long “the House Fairy” continued leaving her love notes.

18、torms. After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London. Now scientists believe that this peak could result in vast solar explosions that could throw billions of
19、 tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcasts from London. The Suns activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum
20、 which could affect the functions of communications satellites, said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxford shire. At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Suns atmosphere, throwing out
21、great quantities of electrically-charged matter. “A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometers per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communication
22、s, Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots. Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are
23、10 times clearer than the most advanced televisions available. The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.Professor Richard Hold away, the labs director, said that the SDO should be able to
24、provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth If we have advance warning, well be able to reduce the damage. What you dont want is things switching off for a week with no idea of whats caused the problem, he said.1. The phrase communicatio
25、ns blackout in paragraph 1 most probably refers to during the 2012 Olympics. A. the extinguishing of the Olympic torch B. the collapse of broadcasting systemsC. the transportation breakdown in London D. the destruction of weather satellites2. What can be inferred about the solar activity described i
26、n the passage? A. The most fatal matter from the corona falls onto Earth. B. The solar storm peak occurs in the middle of each cycle. C. It takes several seconds for the charged matter to reach Earth. D. The number of sunspots declines after coronal mass ejections.3. According to the passage, NASA w
27、ill launch a satellite to _. A. take images of the solar system B. provide early warning of thunderstorms C. keep track of solar activities D. improve the communications on Earth4. Which of the following might be the best title of the passage? A. Solar Storms: An Invisible Killer B. Solar Storms: Ea
28、rth Environment in DangerC. Solar Storms: Threatening the Human RaceD. Solar Storms: Human Activities to Be TroubledBComputerized trading agents may help humans build better marketsTHANKS to declining markets, investment banks are getting rid of many of their highly-paid traders. When markets recove
29、r, the banks might be tempted to replace them with rather cheaper talent. One alternative has been around for a while but has yet to catch on: autonomous trading agents-computers programmed to act like the human version without such annoying costs as holidays, lunch breaks or bonuses. Program tradin
30、g has, of course, been done before; some blamed the 1987 stock market crash on computers instructed with simple decision-making rules. But robots can be smarter than that. Dave Cliff, a researcher at Hewlett-Packard Laboratories in Bristol, England, has been creating trading robots for seven years.
31、In computer simulations he lets them evolve genetically, and so allows them to adapt and fit models of real-world financial markets. His experiments have suggested that a redesign of some markets could lead to greater efficiency. Last year, a research group at IBM showed that Mr. Cliffs artificial t
32、raders could consistently beat the human variety, in various kinds of market. Nearly all take the shape of an auction(拍卖). One well-known type is the English auction, familiar to customers of the salesrooms(拍卖场)of Christies and Sothebys, where sellers keep mum on their offer price, and buyers increa
33、se their bids by stages until only one remains. At the other extreme is the Dutch auction, familiar to 17th-century tulip-traders in the Netherlands as well as to bidders for American Treasury bonds. Here, buyers remain silent, and a seller reduces his price until it is accepted. Most markets for sh
34、ares, commodities, foreign exchange and derivatives are a mixture of these two types: buyers and sellers can announce their bid or offer prices at any time, and deals are constantly being closed, a so-called continuous double auction.Mr. Cliffs novel idea was to apply his evolutionary computer progr
35、ams to marketplaces themselves. Why not, he thought, try and see what types of auction would let traders converge(趋同) most quickly towards a balance price? The results were surprising. In his models, auctions that let buyers and sellers bid at any time like most of todays financial exchanges were le
36、ss efficient than ones that required relatively more bids from either buyers or sellers. These evolved auctions also withstood big market shocks, such as crashes and panics, better than todays real-world versions. Mr Cliffs most recent results, which will be presented in Sydney, Australia, on Decemb
37、er 10th, show that the best type of auction for any market depends crucially on even slight differences in the number of buyers and sellers.Bank of America has been investigating these new auctions, along with robotic traders, for possible use in electronic exchanges. The hope is that todays financi
38、al auctions and online marketplaces might work better by becoming more like their English and Dutch ancestors. 5. What is the passage mainly about?A. A review of two kinds of auctions. B. An introduction of trading robots.C. A survey of the trading market. D. About trading alternatives.6. Which of t
39、he following is true according to the text?A. Mr. Cliffs robot traders have now been used in real-world markets. B. Robot traders can evolve like creatures.C. There is room for improvement in efficiency in trading markets.D. The English auction is the most popular trading form.7. What can we infer f
40、rom the text?A. Existing auctions cannot withstand market shocksB. The Dutch auction is better than the continuous double auctionC. Its hard for traders to reach a balanced priceD. The best type of auction takes place when the number of the buyers is equal to that of sellers 8. Whats the authors attitude toward robot traders? A. Prejudiced B. Objective C. Critical D. Optimistic
