Ministers are aware that the change in the law will be as controversial as the law which legalized abortion (堕胎）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 (排异反应） 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.
小题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 |
| A．Ministers | B．Scientists |
| C．Church leaders | D．Anti-abortion campaigners |
| 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. |

举一反三
In his weekly speech , the President insisted the US could reduce its need for imported oil and improve safety. Using his speech to tell Americans that he understood their concerns about rising prices, President Obama focused particularly on the price of fuel, which has risen in recent months.
US consumers have historically enjoyed cheap fuel , but have seen prices rise in recent months even though US oil production in 2010 reached its highest level for seven years.
Although the oil spill in the Gulf of Mexico in 2010 was serious, Mr Obama said the Gulf remained a key part of the country’s future energy supply.
The President’s proposals (议案）come after Republicans (共和党人） introduced a series of proposals that would expand and speed up oil and gas production.
The White House has criticized the Republican proposals for safety reasons , but Mr Obama was clear in his speech that he felt safety and environmental standards could be maintained even though production might rise.
“ I believe that we should continue to expand oil production in America —even as we increase safety and environmental standards ,”he said.
“As a nation, we should be investing in the clean, renewable sources of energy that are the solution to high gas prices.”
Mr Obama has previously called for a step-change in energy policy, saying the US must move towards getting 80%of its electricity from clean energy sources by 2035.
小题1:Which of the following is NOT included in Mr Obama’s speech?
| A．The dependence on imported oil. |
| B．Improving safety standards |
| C．The reason for the rising oil prices . |
| D．Expanding oil production. |
| A．Not safe enough | B．Not environmentally friendly |
| C．Practical | D．Clear |
| A．The US has got most of its electricity from clean energy. |
| B．US oil production is too small to keep the present low fuel prices. |
| C．The US produced the most oil in 2010 in its history. |
| D．The Gulf is still important in energy supply in spite of the oil spill in 2010. |
| A．Obama: US will seek oil in Alaska and Gulf of Mexico. |
| B．Obama: US will import less oil to improve safety and environmental standards . |
| C．Obama: the time of high fuel prices will be gone. |
| D．Obama: clean, renewable sources of energy are the solution to high gas prices |
People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave.
According to Russian space agency Roscosmos, the fireball, travelling at a speed of 30km per second, had burnt very brightly across the horizon, leaving a long white trail that could be seen as far as 200km away. Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted.
“I was driving to work, it was quite dark, but it suddenly became as bright as if it were day,” said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains. “I felt like I was blinded by headlights.”
The meteorite, which weighed about 20 tons and may have been made of iron, entered Earth’s atmosphere and broke apart 30-50km above ground, according to Russia’s Academy of Sciences.
The energy released when it entered the Earth’s atmosphere was about several thousand tons, the academy said, the power of a small atomic weapon exploding.
No deaths were reported, but the Emergencies Ministry said 20,000 rescue and clean-up workers were sent to the region after President Vladimir Putin told Emergencies Minister Vladimir Puchkov to ease the disruption and help the victims.
The Interior Ministry said about l,200 people had been injured, at least 200 of them children, and most from broken pieces of glass.“While events this big are rare, an impact that could cause damage and death could happen every century or so. Unfortunately there is absolutely nothing we can do to stop impacts.”
小题1:When did the meteorite incident happen?
| A．At midnight. | B．In the early morning. |
| C．In the late morning. | D．In the evening. |
| A．some deaths | B．road accidents |
| C．communication problems | D．building collapse |
| A．a little slow but effective | B．quick and serious |
| C．cold and slow | D．quick but ineffective |
| A．is nearly unavoidable | B．happens every few years |
| C．can be avoided | D．is hard to estimate |
All the original coaches are back for the third season in a row: Christina Aguilera, Maroon 5 lead singer Adam Levine, Cee Lo Green and Blake Shelton. The show’s other on-air talent returning for Season 3 are host/producer Carson Daly and social media reporter Christina Milian, who has been with the show since Season 2. The grand prize for the winner is also the same: a record deal with Universal Republic Records.
The third season of “The Voice” features two big new changes: “steals”, in which the coaches can steal contestants who have been rejected from another coach’s team, and “knockout rounds”. In the “battle rounds,” two contestants face off in a duet (二重唱) of a song chosen by their coach. When a contestant is rejected from a team after a battle round, another coach has the option to “steal” the contestant for his or her team. If more than one coach wants the same contestant, then the contestant gets to choose the coach. In the “knockout rounds,” two contestants face off by each doing a different song of the contestant’s choice, and coaches can no longer “steal” a contestant who is rejected.
Season 3 will also have a new group of four advisers, who are each paired with a coach: Green Day lead singer with Aguilera; Mary J. Blige with Levine; Michael Bublé with Shelton; and Matchbox Twenty lead singer Rob Thomas with Green. At an August 2012 press event held at “The Voice” executive producer Mark Burnett’s home in Malibu, California, members of the media gathered for a press conference with Burnett, Aguilera, Green, Shelton, Levine, Daly and Milian to discuss changes in the show and what the future holds for “The Voice.”
小题1:What does the underlined word “aired” in Paragraph 1 mean?
| A．open | B．perform | C．sing | D．broadcast |
| A．Finance | B．Current affairs | C．Tech | D．Entertainment |
| A．“The Voice” has earned the recognition of critics and Emmy voters. |
| B．The prize of “The Voice” remains the same as the previous year. |
| C．“The Voice” has become the biggest world entertainment of 2012. |
| D．All the original coaches are back for the third season in a row. |
This is what the people in the Philippines used to believe – until they met the “super typhoon”, Haiyan.
The typhoon hit the country on Nov 8, at around 5 am, when most people were still asleep. But being at home didn’t keep them safe, since few buildings remained standing once they were hit by wind as violent as 376 kilometers per hour, according to NBC News.
“This is at the top end of any tropical system that we’ve seen on our planet,” said Bryan Norcross, a weather scientist working for NBC. And so far, Haiyan has caused more than 3,600 deaths and left millions of people homeless.
.But where did Haiyan get its destructive power?
According to Brian McNoldy, a tropical weather expert at the University of Miami, US, Haiyan was so strong because “it had everything working for it”
“All typhoons feed off the warm ocean waters,” Colin Price, a weather researcher at Tel Aviv University in Israel, told National Geographic. Tropical storms are like giant engines（发动机），powered by the heat transferred（传导）from the ocean waters to the air above. However, because of climate change, the oceans have been warming up in recent decades. “Warmer oceans will result in more intense（强烈的）storms，” Price said.
Also, Haiyan started near the equator（赤道），where it was able to pick up more heat before heading to the Philippines. Moreover, the route（路线）it traveled was mostly along open ocean, which means no land prevented it from gathering steam（水蒸气）．
In addition, there happened to be very little “wind shear（风切变）in the area this time. Wind shear is a sudden change in wind speed or direction, which can tear apart developing storms. This is like when you stir（搅动） a glass of water with a chopstick: a swirl（漩涡）will form, ‘but if you move the chopstick in the opposite direction, the swirl will quickly disappear.”
“When all those things align in a certain way, you’re going to get something like‘Haiyan’.”Jim Kossin, a scientist with the US National Oceanic and Atmospheric Administration, told National Geographic.
小题1:Which of the following is TRUE about typhoons according to the article?
| A．They mostly happen early in the morning. |
| B．They mostly do damage during winter. |
| C．During most typhoons people can keep safe just by staying at home. |
| D．This year, more intense storms have happened in the world, |
a, lts starting point was the equator
b, The frequency of other intense storms
c. More heat was transferred from the ocean waters to the air above,
d. There was a strong wind shear in the area
e. There was no land in its way
| A．abc | B．acd | C．ace | D． ade |
| A．disappear | B．affect each other |
| C．Arrive at the top | D．Happen at the same time |
| A．how destructive Haiyan was |
| B．Why Haiyan was so destructive |
| C．how typhoons like Haiyan form（形成） |
| D．ways to protect yourself when typhoons hit |
Payton Karr, 16, and Kiona Elliot, 18, attended the fair as representatives of the project.“We were hoping President Obama would ride the bike, but we didn’t actually expect him to,” Payton told TFK. “ It really meant a lot.” Kiona agreed. “It was pretty awesome to see the invention, which was invented by a group of 14 high school students and one teacher, along with the help of community members, got the interest of the leader of our nation,” she said.
The project was an idea that came about after one of the Northeast students, Kalie Hoke, visited Haiti after the terrible 2010 earthquake and saw how difficult it was to find clean water. The students invented a portable(便携的), bicycle-powered emergency water filtration system, which can provide 20-30 people with drinking water in a 15-hour period. The teens hope their invention will one day be used by relief organizations like the Red Cross. “ They can take it to places after natural disasters so that water can be clean for the people there,” said Payton.
Payton and Kiona were among the 100 students from more than 40 states invited to the third annual White House Science Fair, in Washington, D.C., which is also attended by leaders in science and education. President Obama started the event in 2010 to stimulate students interested in STEM (Science, Technology, Engineering, Maths).“Well, if you’re a young person and you produce the best experiment or design, you ought to be recognized for that achievement,” Obama said when he first announced the fair.
President Obama praised the projects during a speech to attendees after the fair. “The science fair projects of today could become the products and businesses of tomorrow,” he said. “If you’re inventing things in the third grade, what are you going to do by the time you get to college?”
小题1:What is special about the bicycle President Obama rode?
| A．It can move very fast. |
| B．It is extremely beautiful. |
| C．It is used to make water clean. |
| D．It is made of eco-friendly materials. |
| A．were both community members |
| B．graduated from a famous university |
| C．finished the project with the help of their parents |
| D．were surprised that their invention interested Obama |
| A．at the request of the Red Cross |
| B．for city families to get pure water |
| C．during the terrible 2010 earthquake in Haiti |
| D．to provide people in disaster areas with clean water |
| A．help | B．inspire | C．change | D．entertain |
| A．wanted the youth to have big dreams |
| B．encouraged the youth to go to college |
| C．worried the young inventors would do nothing in college |
| D．believed the young inventors would have a promising future |
