Everywhere man is altering the balance of nature．He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously．He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization．He exterminates some species on a large scale, but favors the multiplication of others．In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million．
Many of these changes which he has brought about have had unforeseen consequences．Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers’ wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semi desert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece?
These are spectacular examples; but examples on a smaller scale are everywhere to be found．We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested．We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes．We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock．

A．man is covering huge areas with new kinds of plants

C．man is killing some species on a large scale

小学生10分钟应用题系列答案The US government has started a website, Admongo, to help children think critically about the advertising aimed at them. It claims to provide visitors with an “aducation” through games and other entertainment.
A cartoon man dressed in old time pilot clothing greets visitors to Admongo. "Call me Haiz", he says upon arrival in a rocket ship that opens up with a crazy world inside it. Spacey dance music plays in the background as Haiz tells visitors that they need to learn about advertising.
Its inventors say eight to twelve years old is the age kids develop their critical thinking abilities. Kids that age are also a big market for advertisers.
The idea behind Admongo is to teach children three things: To identify the advertiser. To know what the advertiser is really saying. And to know what the advertisement is trying to get the child to do.
Children learn these things through a video game. They create their own game character. They can choose different skin colors, hair styles, eye and mouth shapes. Then they begin a trip through ad-land, where there are ads on buses and billboards. The players have to find all the marketing in the neighborhood before they can move on to the next level.
The Admongo game takes players inside a home, to the advertising studio and everywhere else ads can be found. It is a complete exploration of the world of marketing.
One such area is food marketing. The Federal Trade Commission (FTC) says it is a big business. The FTC estimates that food, drink and fast-food restaurants spent more than one and a half billion dollars on advertising to young people in 2009.
The FTC says children are important for three reasons. They buy products. They influence parents and caregivers to buy. And they are the future adult buyers of the products.
A recent study says most advertising aimed at children is for foods of the lowest nutritional value. First Lady Michelle Obama has said she would like to see advertisers marketing healthy foods for children.

The wife-carrying World Championship has been celebrated in a small town in central Finland since 1992. In 1992, the people of the town decided to restart some long-forgotten traditions. 46 He was said to only accept men as members of his gang who proved their worth in challenges. At that time, it was also a common practice to steal women from neighboring villages.
47 A large number of competitors, people, and journalists from Finland to Canada attend the Wife-carrying World Championship every year.
48 The Wife-carrying World Championship is held on a 253.3 meters long official track. The track has two dry obstacles and a water obstacle, about a meter deep. The wife to be carried may be your own, or your neighbor’s. The minimum weight of the wife to be carried is 49 kg. If she is less than 49kg, the wife will be given a heavy bag to carry. Each time a competitor drops his wife, that couple will be fined 15 seconds. 49
Alongside with the Wife-carring World Championship, there is also a team competition. The distance is the same but three men in the team carry the wife in turns. At the exchange point the carrier has to drink official “wife-carrying drink.” Then he may continue the race. 50

| B．People everywhere hold the event. |
| C．A special prize is awarded to the team. |
| D．Do you know how these traditions restarted? |
F．The winner is the couple who complete the course in the shortest time.

If you hear the sound of running water the next time you call a co-worker on his or her mobile phone, don’t be surprised. Three-fourths of Americans with mobile phones say they use them in the bathroom, a new study shows.
Approximately(大约) the same number of men and women have used the phone in the bathroom, according to a survey of 1,000 Americans by 11 mark, an integrated marketing agency, although men seem more attached to IT in the toilet: 30 percent of men versus(VS) 20 percent of women agreed with the statement, "I don't go to the bathroom without my mobile phone."
More than half the surveyed users (63 percent) said they have answered a phone call in the bathroom, and almost half (41 percent) reported initiating a phone call. That's not all, however. What goes on behind the walls of the stalls(小隔间) is anything a mobile phone is capable of. Sixty-seven percent said they have read a text, and 39 percent have surfed the Web. Men work more from the bathroom — 20 percent said they have participated in work-related calls, versus 13 percent of their female colleagues.
As expected, Gen Y(1981年后出生的一代) respondents(调查对象) are the pacesetters(先导者) in the "mobile everywhere" movement, with 91 percent using their phone in the bathroom. Still, older generations are not far behind. Eighty percent of Gen X(1961-1981) reported using the phone in the bathroom, as did 65 percent of Baby Boomers(1946-1965) and 47 percent of the Silent Generation(1925-1945).
While online, they are doing more than just surfing; 16 percent of Gen Y report they have made an online purchase while in the bathroom. Users of iPhones are particularly likely to browse and buy in the bathroom – 22 percent have made a purchase, versus 10 percent of Americans with mobile phones overall.
"The writing is on the stall," said 11 mark principal Nicole Burdette. "This study confirms what we all know: that the last private place is no longer private."
In the process, high-tech hygiene(卫生) is taking a hit, the survey found. While 92 percent of mobile phone users said they wash their hands after using the bathroom, only 14 percent said they wash their phones.
1.Which is the best word to replace the underlined word "initiating"?

A. no wonder mobile phones are used in the bathroom
B. the bathroom is a private place for people
C. it makes people have no privacy at all
D. more men have used the phone in the bathroom
3.What does the last paragraph of the passage imply?
A. Using phones in the bathroom has a bad effect on hygiene
B. Mobile phones should not be allowed to use in the bathroom
C. Most people care about the hygiene after using the bathroom
