About a year ago，if you had asked who Dinara Safina was，the answer would have been，“She is Marat Safin’s younger sister.” She was overshadowed by her wonder brother.But now she has made a name for herself：the world No.1 player in women’s tennis.

The 22?year?old Russian overtook Serena Williams of the US for top ranking on April 20.“Before，every place I go，I am Marat’s sister.Nothing else，”she told New York Times.“I always wanted to be myself，and now finally the results come，and people can know me as Dinara Safina.”

Safina has made it to two great event finals，in the 2008 French and in the 2009 Australian Open，and won a silver medal in the Beijing Olympic Games.

Clearly，family isn’t the only connection Safina and her brother share.Their DNA burns with competitive fire.Safin has held the distinction for years of being a hottempered player on court.When he lost his temper，he would smash a racket (球拍)．Safina is as emotionally explosive as her brother.A headline in the newspaper The Australian once described her as “mad as a snake”．The Sydney Morning Herald，during the Australian Open，summed up Safina’s volatile (不稳定的) emotional state with the headline—Safina goes from basket case to top of the world.

It’s not rare for a family to have two top tennis players.Safina’s father owns a tennis academy and her mother worked as a coach.“I had no choice but to become a tennis player，but I don’t mind being a tennis player，” Safina said.

From this talented family she is also given one of her best weapons on court，her size.She is 1.82 meters tall and weighs 70kg.But it is hard work that led her to her recent success.

“I hope to prove to everyone over the coming months that I deserve the honor of being world No.1，”she said.

The rat is named Lola and she’s at the top of her class of risk-running animals being trained to smell out landmines (地雷) in Colombia, home to the world’s highest number of mine-related deaths and injuries last year. Of the victims, many are children who died in the accidents while walking to school or playing in the countryside.

The smartest rat among the first six that the government is teaching to locate landmines equipment planted by rebels(叛乱者) has a 90 percent success rate in locating landmines material in her lab training.

Police animal trainers, tired of seeing their landmines-smelling dogs blown up by stepping on mines, hope the white-furred, pink-eyed creature will lead her classmates through coming open field tests and then into the country mine fields before the end of the year. It takes about 400 grams of pressure to detonate (引爆) a mine while Lola only weighs about 220 grams. “The dogs can easily set off the landmines, sometimes killing people nearby,” they said.

Police animal trainer Jose Pineda says that rats have more sensitive noses than dogs, which should allow them to better smell out mines in difficult terrain (地形).

Plus, it takes the police about six months to train mine-smelling dogs. Training the rats is expected to take about half that time once the program is established.

Trainers think that they are much smarter than the dogs. The second-best scorer in the laboratory is Lucrecia, with an 83 percent success rate. Males, such as one named   Runcho, have fallen behind until now but may do better in the coming field tests. Pineda said that the next step of training will present new challenges to the rats as they are sure to meet distractions (分心的事) in the open.

3.What can we learn from the last paragraph?

B. Until now, female rats are better than the male ones.

However urban life strikes you, cities worldwide have been growing ever more rapidly. Some of this growth has occurred in the developed world, but the most dramatic increase has been in the Third World. Almost all the world’s population growth over the next 30 years will take place in the cities of developing countries.
By the year 2030, for the first time in history, 60 percent of the world’s people will be living in cities.
This is actually good news in some ways. “Cities are the fundamental building blocks of prosperity（繁荣）,” says Marc Weiss, chairman of the Prague Institute for Global Urban Development, “both for the nation and for families.” Industrial and commercial activities in urban areas account for between 50 and 80 percent of the gross domestic product (GDP) in most countries of the world “there’s the crazy notion that the way to deal with a city’s problems is to keep people out of them,” Weiss continued. “But the problems of the rural life are even more serious than those of the city.” For better or worse, urban-watchers are clear on one point: The quality of life for most people in the future will be determined by the quality of cities. Those cities will be bigger than ever. And yet, population numbers by themselves don’t determine a city’s prospects; after all, Addis Ababa, Ethiopia, and Hamburg, Germany, have the same population. Nor is explosive growth necessarily the determining factor. “City problems,” one authority points out, “mostly have to do with weak, ineffective, and usually unrepresentative city governments.”
【小题1】According to the passage, in the year of 2030 _______.

In the competition of Olympic weightlifting，the athletes try to lift the maximum (最大的) weight they can. There are special conditions they have to meet in order to compete：body weight，height and strength.
The Olympic weightlifting mainly tests the limit of explosive strength (爆发力)．There are not many lifters who really like Olympic weightlifting and the explanation is very simple：they are short of explosive strength.
The weights used for Olympic weightlifting are added in kilograms. The order by which the athletes enter the competition is not general，but it is set depending on the event. Usually the athlete with the lowest weight begins. If he/she is not successful，he/she can try later. There is a maximum of three lifts allowed for every competition.
For many years Olympic weightlifting was only for men. However，now women also take part in Olympic weightlifting. It was at the beginning of the 21st century that women’s competitions entered an organized professional environment. For women，Olympic weightlifting is more difficult because of their different body structure. However，strength training techniques (技术) are widely and successfully used by women，too.
Lots of the athletes who’ve ended up in Olympic weightlifting competitions have started with strength training only to improve their muscle condition and their body power. However，the demarcation line (界线) is not still very clear between power training and Olympic weightlifting. This is how so many lifters have got into Olympic weightlifting competition，even if their purpose was different at the beginning.
【小题1】In the competition of Olympic weightlifting，athletes need to be all of the following EXCEPT________.
