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.

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 |
D.avoid falling down to the ground |
A.fastgrowing | B.harmless |
C.insectkilling | D.nutritious |
A.evolution of species |
B.helps from other garden plants |
C.artificial cultivation |
D.nutrients preserved in rich soil |
A.a student book | B.a science fiction |
C.a scientific repot | D.a bulletin board |
Asian carp are strong to jump over barriers such as low dams. They lay hundreds of thousands of eggs at a time and spread into new habitat quickly and easily. Also, flooding has helped the fish expand into previously unattainable water bodies. And fishers using young carp as live bait have also helped the fish"s spread, as they have boats going through locks up and down the Mississippi.
The federal government considers the Asian carps to be annoying species and encourages and supports “active control” by natural resources management agencies. Federal and state governments have spent millions in tax dollars to prevent the carp from making their way into the Great Lakes, but an underwater electric fence constructed to keep them out has not worked as well as hoped, and policymakers are reviewing other options now.
In the meantime, state and federal agencies are monitoring the Mississippi and its branches for Asian carp and testing various barrier technologies to prevent their further spread. For instance, the National Park Service is cooperating with the state of Minnesota"s Department of Natural Resources to construct new dams that are high enough to prevent Asian carp from jumping over. The Asian Carp Regional Coordinating Committee has funded DNA monitoring in potentially affected water bodies whereby researchers can determine whether the troublesome fish are present just by the biological footprints they leave behind. Individuals can do their part by not transporting fish, bait or even water from one water body to another, and by emptying and washing boats before moving them between different water bodies.
小题1:Asian carp have been introduced to the USA in order to ________.
A.improve water quality |
B.help sensitive species |
C.control the number of native fishes |
D.control the ecosystem in aquaculture |
A.testing various barrier technologies |
B.construction of an underwater electric fence |
C.Emptying and washing boats before using them. |
D.monitoring the Mississippi and its branches for Asian carp |
A.aquaculture operations are dangerous to the water bodies |
B.scientific technology is useless in preventing Asian carp spreading |
C.both the state and the individuals can make efforts to keep out Asian carp |
D.Asian carp have successfully invaded the Mississippi and the Great Lakes |
That American high schools spend more time and money on sports than on math is an old complaint. In December, when the latest Program for International Student Assessment (PISA) results are announced, it"s safe to predict that American highschool students will once again show their limited skills in math and reading, outscored not just by students in Poland but also by students in places like China, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.
Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D.C., which costs thirty thousand dollars a year. The tour leader a mother with three children in the school was asked about the school"s flaws (瑕疵). When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really?” one of them asked worriedly, “What do you mean?”
One of the ironies of the situation is that sports show what is possible. American kids" performance on the field shows just how well they can do when expectations are high. It"s too bad that their_test_scores_show_the_same_thing._
小题1:Tom decides to spend his senior year in Poland because ________.
A.he intends to improve his scores |
B.Polish kids are better at learning |
C.sports are not supported at schools in Gettysburg |
D.he wants to be the smartest kid in the world |
A.PISA plays a very important role in America |
B.little time is spent on sports in Japanese schools |
C.American students do better in both math and sports |
D.too much importance is placed on sports in America |
A.low expectations result in American students" poor PISA performance |
B.high expectations push up American students" academic performance |
C.American students" academic performance worries their parents a lot |
D.lacking practice contributes to American students" average performance |
A.compare Polish schools with those in America |
B.call on American schools to learn from the Polish model |
C.draw public attention to a weakness in American school tradition |
D.explain what is wrong with American schools and provide solutions |

So, the bottom line is that no matter how strong your passwords are, and no matter what clever tricks you use to help you remember them, if you surf internet often, the only truly secure password system is what you need.
Enter LastPass. It"s not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database. The LastPass database is stored online, on LastPass"s servers. LastPass recognizes the site you"re on and automatically logs you in (after, optionally, asking you to reenter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different, unique, very strong password for every site you log into, but you only have to remember one master password. It"s the best of both worlds.
One argument against LastPass is that if their database is attacked, then all of your sites are in danger, and that"s true, but given that their entire line of work is keeping that information safe, I"m willing to take that chance. The alternative is rolling dice(掷骰子) or picking phrases to create passwords, writing all of them down on a piece of paper or something, and then having to manually type them in when I go to a site. A terrible mess.
There is a free version of LastPass, with some additional features unlocked if you pay a $12 a year subscription.
