As we enjoy the summer ocean waves along the beaches, we may think nervously about Steven Spielberg"s Jaws and the great fear that sharks inspire in us. Yet we are happy to see global efforts to protect the declining number of sharks. The world has realized that we need the species, like sharks, to keep a balanced ecosystem.
Sharks, in particular, are “in” these days. Thanks to good public policy and famous stars such as Jackie Chan and Ang Lee, killing sharks for fin soup is no longer cool.
The demand for shark fins has been rising for decades, threatening sharks with extinction(灭绝)—up to 100 million sharks are killed each year just for their fins. But we have started to reverse the trend, particularly in many areas of the United States and overseas where restaurants once proudly provided delicious shark fins on the menu.
In California, a ban on the sale and possession of shark fin soup has gone into effect this year through the efforts of Wild Aid and other organizations.
Overseas marketing and public efforts featuring posters on public transportation systems and TV ads have been underway for the past few years. These efforts all show signs of success, on both the supply side and the demand side of trade in shark fins.
Actually, stopping the killing of sharks is part of a broader movement to stop the killing of wild animals and the buying and selling of wildlife products. These products come from hunting elephants, tigers and rhinos, besides killing marine life.
Whether it is shark fin soup or ivory piano keys, killing animals is big business. The hunting of elephants in search of ivory tusks for luxury(奢侈的)goods has become a full­scale war. The decrease of African elephant populations is alarming. Together with international partners, the United States is leading the worldwide effort to reduce demand for high­end products that rely on killing animals.
小题1:The underlined word “reverse” in Paragraph 3 probably means ________.
A.showB.keep
C.followD.change
小题2:From the passage, we know ________.
A.Jackie Chan and Ang Lee make fin soup popular
B.a lot of wild animals have been killed for products
C.Steven Spielberg"s Jaws inspires us to protect sharks
D.the number of African elephants has been increased
小题3:.What can we infer from the passage?
A.More animals for high­end products will be saved.
B.People have kicked the habit of having shark fin soup.
C.Shark fins will not be available any more in restaurants.
D.Global efforts have succeeded in stopping killing wild animals.

答案

小题1:D
小题2:B
小题3:A
解析

文章大意:对野生动物的保护正在进行中。
小题1:D 猜测词义题。由转折词But可知,所在句意为:我们已经开始“扭转”这一趋势。
小题2:B 细节理解题。由第二段第二句话“Thanks to good public policy and famous stars such as Jackie Chan and Ang Lee, killing sharks for fin soup is no longer cool.”可知,成龙和李安使鱼翅汤不再流行,所以A项错误;由第一段第一句话“As we enjoy the summer ocean waves along the beaches, we may think nervously about Steven Spielberg"s Jaws and the great fear that sharks inspire in us.”可知,斯皮尔伯格的《大白鲨》使人们产生了对鲨鱼的恐怖,所以C项正确;由最后一段第三句话“The decrease of African elephant populations is alarming.”可知,D项错误;由倒数第二段可知,B项正确。
小题3:A 推理判断题。由最后一段最后一句话“Together with international partners, the United States is leading the worldwide effort to reduce demand for high­end products that rely on killing animals.”可推知,在全世界人们的努力下,更多的动物会受到保护。所以A项正确;其他三项都不对。

(London)­If it really is what"s on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn"t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body"s communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle,” Bell said.
小题1:What is this piece of news mainly about?
A.Thin people also have troubles.
B.Internal fat is of no importance.
C.Internal fat leads to many diseases.
D.Thin people may be fat inside.
小题2:Doctors have found ________.
A.being slim doesn"t mean you are not fat inside
B.internal fat is the cause of heart disease and diabetes
C.being slim is not dangerous at all
D.the exact dangers of internal fat
小题3:According to the passage, which of the following is WRONG?
A.People with heart disease all have internal fat.
B.People can get rid of internal fat by improving diet.
C.Men are more likely to have too much internal fat.
D.Exercise can help to reduce the internal fat.

Pupils remember more and behave better when 3D images areused in lessons,research suggests.They are quicker to learn andabsorb new concepts,and display higher levels of concentration.
Professor Anne Bamford,of the University of the Arts,London,studied the effectiveness of 3D content in 15 schools across seven countries,including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks,improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿动作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding,increased attention span, more motivation and higher engagement in the lessons.
Children are used to 3D with the rise of computer games that use the technology­90 percent of those in the study had seen a 3D film.Schools would need 3D­enabled projectors(投影仪),laptops with good picture capabilities,3D software and glasses for children to introduce animations(动作) into classrooms.
But Danny Nicholson,an educationist,said the technology would be impractical to use inschools and could be costly.He said,“While I think the idea of 3D technology is very interesting,I worry that 3D is a bit of an expensive gimmick(小玩意儿).There are a few cases where a true3D image might help,but most of the time,good 2D models that can be moved would be just aseffective.”
In the US,one school district in Colorado is already in the process of having 1,000 3Dprojectors fixed in classrooms.And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.
小题1:What is the main idea of the first three paragraphs?
A.There are slight differences between 3D and 2D images.
B.Pupils perform better when 3D images are used in classes.
C.Schools have difficulties in making full use of 3D technology.
D.3D technology is always more effective than 2D technology.
小题2:Danny Nicholson holds the view that 3D ________.
A.is of no help in classes
B.has a bright future in classes
C.is more practical than 2D models
D.may not be affordable for schools

The first robot rover to land on the Moon in nearly 40 years, China"s Jade Rabbit, has begun sending back photos, with shots of its lunar lander(登月飞行器). Jade Rabbit rolled down a ramp lowered by the lander and on to the volcanic plain known as Sinus Iridum at 04:35 Beijing time on Saturday (20:35 GMT).It moved to a spot a few metres away, its historic short journey recorded by the lander. On Sunday evening the two machines began photographing each other. A Chinese flag is clearly visible on the Jade Rabbit as it stands deployed on the Moon"s surface.

Ma Xingrui, chief mander of China"s lunar programme, declared the mission (任务)a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China"s ambitious space programme, says BBC science reporter Paul Rincon.
The lander will operate there for a year, while the rover is expected to work for some three months. The Chang"e­3 mission landed some 12 days after being launched atop a Chinese­developed Long March 3B rocket from Xichang in the country"s south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13:00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球车) in Shanghai a few years ago ­ it"s a wonderful technological achievement to have landed,” Prof Andrew Coates, from UCL"s Mullard Space Science Laboratory, told BBC News.
Chang"e­3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod­2, which was kept warm by polonium(钋)­210. But the six­wheeled Chinese vehicle carries a more sophisticated payload(复杂的有效负荷), including ground­penetrating radar which will gather measurements of the lunar soil and crust.
小题1:What does the text mainly talk about?
A.China"s space and aeronautics industry develops quickly.
B.The importance of China"s space and aeronautics industry.
C.China"s Jade Rabbit Moon rover sends back first photos.
D.Chang"e­3 is the third unmanned rover mission to touch down on the lunar surface.
小题2:After ________ years" hard and scientific work, the first soft landing on the Moon has made such great progress.
A.nearly 40B.37
C.64D.more than 40
小题3:The purpose that the Chinese moon rover has visited the moon is to ________.
A.do some research about the moon
B.be the first settler on the moon
C.to plant the Chinese flag onto the moon
D.send a lovely jade rabbit onto the moon
小题4:From the text, we know that the lander began its descent on Saturday just after ________ Beijing time.
A.13:00B.20:00

For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground.
Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”
The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia(矮牵牛), some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.
It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil ­ and even various plants grown in your vegetable garden still have the ability.
The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meat­eating plants,” they added.
小题1:Tomatoes and potatoes kill insects to ________.
A.get more sticky hairs
B.make themselves grow better
C.make their roots stronger
