SAN FRANCISCO—A phone app (應(yīng)用程序) in San Francisco gives information about open parking spots. City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns.
In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think. Now San Francisco has found a solution—a phone app for spot-seekers that displays information about areas with available spaces. The system, introduced last month, relies on wireless sensors (感應(yīng)器) fixed in streets and city garages that can tell within seconds if a spot has opened up.
Monique Soltani, a TV reporter, said she and her sister spent 25 minutes on Friday trying to park. “We were praying to the parking god that we’d find a spot,” she said. “If we had the app, we would not have to pray to the parking god.” But the system could come with serious consequences.
Some people say that drivers searching for parking could end up focusing on their phones, not the road. “It could be really distracting (使分心的),” said Daniel Simons, a professor of psychology at the University of Illinois.
City officials acknowledge the potential problem. They are urging drivers to pull over before they use the city’s iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated.
San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages. If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency. On the app, a map shows which blocks have lots of places (blue) and which are full (red).
More than 12,000 people have downloaded San Francisco’s app, which is available now only for the iPhone but which city officials say they hope to bring to all similar devices.
When it is started up, the city’s parking app warns drivers not to use the system while in motion. But safety advocates said that might not be sufficient. After all, they say, texting while driving is illegal in California and in many states, but a number of surveys, including one by the Pew Research Center, show that many Americans do it anyway.
Elizabeth Stampe, executive director of Walk San Francisco, a pedestrian advocacy group, said she hoped the new parking app would lead to fewer accidents.
“It’s an innovative idea,” she said. “The safe way for people to use the device is for them to pull over, which they know they should do. The question is whether they will.”
But Ms. Soltani, the TV reporter, said using the app would probably join the group of activities already performed by drivers.
“We’re already looking at Google Maps and Facebook on the phone while we drive,” she said. “Aren’t we always looking at something on our phone, or changing the radio, or drinking coffee? You’re always slightly distracted when you’re driving.”
小題1:What is the phone app mentioned in the text mainly aimed at?
A．Making full use of the parking spots.
B．Making the traffic flow smoothly.
C．Preventing traffic accidents.
D．Benefiting iPhone users.
小題2:According to the text, San Francisco city officials ______.

Facebook is now used by 30 million people in the UK, around half the population. Joanna Shields, vice president of Facebook Europe, made the announcement this morning at a media conference in London.
Globally, Facebook has more than 500 million registered （注冊的） users, a milestone it hit last summer. Last July it had 26 million registered UK users. In the last eight months, it has attracted four million extra UK users, bringing the UK total to 30 million.
Facebook, the brainchild of Mark Zuckerberg while he was still studying at Harvard University, was launched in February 2004. The pace of its global growth has sped rapidly - Facebook had only 150 million registered users in January 2009.
One third of women aged between 18 to 34 check Facebook when they first wake up, before even going to the toilet, according to the research. 21% check Facebook in the middle of the night, while 42% of the same group think it is fine to post drunken photos of themselves onto the social network, a study by Oxygen Media and Lightspeed Research found.
Shields was speaking this morning at the Financial Times Digital Media and Broadcasting Conference about the power Facebook’s referrals （好友推薦）can bring to media sites, such as newspapers and TV services. She explained that the average Facebook user has 130 friends who they share links to media sites with regularly. “Media companies which take advantage of that are really seeing the benefits,” Shields said. Shields refused to be drawn on whether Facebook would develop its own mobile phone operating system and also said it was “silly” that Google had recently disabled the feature which allowed Google users to refresh their contacts with Facebook friends.
小題1:Eight months ago the number of registered users of Facebook in UK was about ____.

According to an English newspaper, scientists could begin cloning human embryos in Britain in 2001. It is understood that the government has already agreed to use Frankenstein’s technology, believing the benefits are more important than ethical （倫理的）concerns .Researchers think it will be possible to grow brain tissue to cure the diseases that are likely to get worse as time passes like Alzheimer’s , and produce “spare part” organs like hearts and kidneys for transplant （移植）.
Ministers are aware that the change in the law will be as controversial as the law which legalized abortion (墮胎）more than 30 years ago. Some politicians reacted angrily , arguing that the government had already made up its mind without discussion. Church leaders and anti-abortion campaigners have long expressed their horror at the plans, arguing that even the earliest embryos are forms of human life.They believe that getting an embryo from cells is morally unacceptable . And it will also cause arguments about how far scientists should interfere with nature and lead to accusations that they  are “playing God”.
The cloning of human embryos to provide spare parts is regarded by most experts to be the most important step forward in the 21st century medicine. Scientists say treatment of diseases such as Alzheimer’s and Parkinson’s will be the first application of cloning. The ability to clone embryos was first achieved by scientists in Scotland in the late 1990s and now the ability to grow stem cells into tissues and organs is being developed by American researchers. Combining the two technologies will mean an end to long waits for organs from donors and problems caused by rejection (排異反應(yīng)） of transplanted tissues by the body.
Ian Wilmut, the man who cloned Dolly the sheep, has warned that British experts will go to America, where such work is legal, if the government does not permit it.
小題1:The government has decided to allow scientists to clone human embryos because they think that ____.
A．Frankenstein’s technology is advanced
B．Its advantages are more important than its disadvantages
C．Diseases like Alzheimer’s are a serious problem in their country
D．They can make a lot of money from it
小題2:The underlined word “they”in Paragraph 2 refers to ______.
A．MinistersB．Scientists
C．Church leadersD．Anti-abortion campaigners
小題3:Which of the following statements is NOT true according to the passage?
A．Most experts think that the cloning of human embryos is beneficial.
B．Politicians were in favour of the government’s decision.
C．It is legal for scientists to clone embryos in America now.
D．American researchers are developing the ability to grow stem cells into tissues and organs.
小題4:What’s the best title for this passage ?
A．Science of cloning.

What seemed like an unplanned comment about Syria's chemical weapons (武器) had a major effect on world events this week. American Secretary of State John Kerry spoke last Monday at a press conference in London. He was reacting to questions about possible American action to answer a chemical weapons attack believed to be likely in Syria. One reporter asked the secretary whether there is anything Syria's president can do to avoid an American military (軍事的) strike.
"Sure, he can turn over every single bit of his chemical weapons to the international society in the next week."
Mr. Kerry made it clear that he was speaking theoretically, and did not expect anything like that to happen.
But Russia seized on the idea and persuaded Syria to do the same. That brought plans for American congressional (議會) votes on military action to a halt. President Obama has said he would accept a diplomatic settlement if it can be carried out. But that would likely take weeks, at least.
Mr. Obama has said the government of Syrian President Bashar al-Assad must be punished for breaking the nearly century old ban on the use of chemical weapons. He called for American action to prevent future use of chemical weapons in Syria. He suggested limited airstrikes on government targets. The airstrikes could happen quickly if Congress approves.
Joanna Kidd is a security expert with London's King's College. She says any move to place Syria's chemical weapons under international control would take a long time, if it could be done at all.
小題1:What does the author think of John Kerry’s statement at a press conference in London last Monday?
A．TheoreticalB．PracticalC．UnintendedD．Planned
小題2:What does the underlined word “halt” probably mean?
A．stopB．a(chǎn)ctionC．a(chǎn)ttentionD．debate
小題3:According to the passage, which of the following statement is TRUE?
A．Russia thinks there was a chemical weapons attack in Syria.
B．Russia is against the American military strike on Syria.
C．Obama believes that a diplomatic settlement is on the way.
D．American Congress will approve Obama’s limited airstrikes.
小題4:The belief shared by John Kerry and Joanna Kidd is________.
A．Bashar al-Assad’s administration should be punished for breaking the ban
B．Obama’s government has to prevent future use of chemical weapons in Syria
C．Syria's president can do nothing to avoid an American military strike
D．placing Syria's chemical weapons under international control is hard to achieve

Ethiopia has greatly reduced its death rates for children under the age of five years during the last two decades, new UN statistics show. The report says Ethiopia has cut the number of child deaths, by two thirds or so, to 68 per 1,000 births compared to that in 1990.
The government owed the improved figures to its growing economy. Despite the reduction, the UN Children's Fund said Ethiopia needed to do much more to improve health facilities(設(shè)施) for pregnant women.
Ethiopia is one of Africa's poorest states, although it has experienced rapid economic growth in recent years and is one of the continent's leading coffee producers. Its economy centers around agriculture, which in turn relies on rainfall.
The BBC's Emmanuel Igunza in the capital, Addis Ababa, says Ethiopia was once representative of poor nutrition in Africa. But the latest UNICEF(聯(lián)合國兒童基金會) figures show Ethiopia is one of the few African countries on the path to realizing the development goal of reducing child death rates, he says.
Ethiopia's Health Minister Kesetebirhan Admasu said increasing family incomes had helped improve people's health. "This has also resulted in better nutrition for children and women; this has translated into better medical conditions —— all these have a direct or indirect influence on the survival of children," he told BBC Africa. He said the government has also been "aggressively expanding its primary health care network". 
"We have now 93% coverage( 覆蓋) of one health centre for 25,000 people, which basically means one health facility within a 7km area," he said.
小題1:How many in 1000 births would die in Ethiopia in 1990?
A．a(chǎn)bout 680B．a(chǎn)bout 330C．a(chǎn)bout 68D．a(chǎn)bout 200
小題2:Which of the following statements is true?
A．Ethiopian children benefit from its fastest economy growing.
B．Ethiopia has a long way to go to improve health facilities.
C．Ethiopia is the economic center because of its rich rainfall.
D．Ethiopia has already become a rich state in Africa.
小題3:What do we know according to the latest UNICEF figures?
A．Many African countries have high child death rates now.
B．Ethiopia is the only country that has reduced child death rates.
C．Ethiopia is the most successful in reducing child death rates.
D．Ethiopia was once known for its poor nutrition in Africa.
小題4:What Kesetebirhan Admasu said shows that_______.
A．a(chǎn)gricultural incomes have helped improve all the people's health in Africa
B．now the health care network is perfect in Ethiopia
C．93% of the 25,000 people enjoy health centers in Ethiopia
D．the government has been taking active measures to improve people's health

SYDNEY 2005-01-01 08:33—Mother of two, Jillian Searle, had to choose between her children when she made a life-or-death decision.
Swept up by mountainous tsunami (海嘯) waves at a Thai resort ( 旅游勝地), she could not hold on to both her young sons and survive . Fighting to stay above the waters , she had to choose which one would have to take his chances in the swirling torrent (漩流).
“I knew I had to let go of one of them and I just thought I’d better let go of the one that’s the older,” she told Sky News television in a report broadcast on Thursday. She said she was accompanied by the two boys, Lachie, 5, and two-year-old Blake, and their father, Brad, who had watched the drama helplessly from their first-floor hotel room, when the waves struck. “And I was screaming, trying to find him, and we thought he was dead,” she told reporters on arrival back in Australia. Lachie was found alive about 2 hours later clinging to a door and, looked uninjured as his mother spoke to reporters.
British surfer (沖浪運動員) Martin Markwell is also a lucky man. He had always dreamed of catching that perfect wave –but when it finally came along, it was a nightmare. He was on his surfboard when he was swept up by a tsunami wave.
“It was really terrible because I was surfing, I was really surfing on a wave I wasn’t supposed to be on,” he said. “As an experienced surfer, when I saw the wave come I realized something was wrong, but I couldn’t escape because my surfboard was tied to my ankle.”
His wife Vicki and son Jake looked on in horror from a hotel balcony as he crashed towards the shore. Luckily , he stayed on top of his board until he reached the hotel , jumped off and got to safety as the ocean rolled back to feed a much larger tsunami wave on its way . The family regrouped and ran to safety just minutes before a giant tsunami wave 10 meters high.
小題1:When the waves struck, the father Brad        .
