Terraforming (Earth-forming) other planets, also known as planetary engineering (行星工程), seems like a task still centuries away for mankind to accomplish. However, it is a vigorous topic that attracts both popular and scientific interest. Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it’s a good idea?
Mankind is getting more and more hard facts about other planets. The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury, Jupiter and Saturn have been studied by spacecraft. Speculations have been answered; new questions have been raised, and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.
In the past, people with excellent ideas about terraforming have kept them to themselves, or buried them in a desk drawer because they did not realize that anyone else was interested. But now, a wide circle of people has begun to do this kind of work. For instance, NASA funded a project on transforming Mars.
There are several strong reasons which demand that the possibilities of terraforming be studied carefully. First, it’s an exciting idea of a possible future for human beings. Such thinking has a valuable role in providing options for our future directions. Secondly, the techniques of terraforming will also help contemporary technologies in weather and climate control. Thirdly, such study may assist us in detecting any possible existence of extraterrestrial intelligence (SETI, The Search for Extraterrestrial Intelligence, 地外文明搜索) and alien (异己的) civilizations on other planets.
Though the mission is far beyond our reach at the moment, we should at least keep our options open. Through debate and study on this subject, the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future.

Sixteen brave runners recently gathered in the Russian village of Oymyakon, also known as the world’s pole of cold, to compete in the coldest official race in history.
Oymyakon is the coldest permanently inhabited place on Earth, with temperatures constantly dropping to under -50 degrees Celsius in winter time. This place is so cold that a person’s unprotected face can suffer frostbite(冻伤) in a matter of second. Oymyakon can barely be called livable, let alone suitable for a marathon, and yet at the beginning of this year, 16 runners gathered here to take part in a series of extreme races.
On January 5, the brave runners — aged 21 to 71 and very well-trained — competed in bone-chilling marathons for 5, 10, 20, 30 and 42 kilometers across the frozen taiga(泰加森林) of central Yakutia.

Every year from March to October, Christian Moullec, also known as “Birdman,” takes to the skies aboard his adapted light aircraft. However, the 58-year-old Frenchman’s daily 30-minute flight is not just to enjoy the impressive views, but to guide flocks (鸟群) of lesser white-fronted geese (小白额雁) through safe migration paths which the birds can teach future generations.
His deed began in 1995 when he noticed their declining population in the wilds of Lapland, Sweden. To prevent their numbers from dropping further, Moullec tried to get the threatened species to follow him along migration routes that would protect them from bird hunters.
However, getting grown geese to follow his lead proved challenging. As young geese imitate and follow whomever they view as their parent, Moullec decided to raise the geese from birth.
To help raise funds and awareness of his job to protect not just the geese but birds worldwide, Moullec often allows paying tourists to join him on the 30-minute-long flights aboard his aircraft. In addition to the trained birds flying alongside them, visitors, who come from as far as a 15-hour plane flight away, are treated to a variety of crane and geese species as well as breathtaking views of castles and cities.
He often brings his camera along for the flights, capturing photos not just for their beauty, but for what they describe. Moullec believes the use of agricultural chemicals has done harm to wild European birds, with more than a third disappearing in the last 30 years. “It's a disaster,” he said. “My beautiful images with flying birds should be used to tell this story. ”
1.Why does “Birdman” always fly to the sky on his aircraft?
A.To observe geese along their migration routes.
B.To follow geese through safe migration paths.
C.To take visitors to operate his adapted aircraft.
D.To guide geese fly safely during the migration.
2.What do we know about “Birdman”?
A.He is a nature lover. B.He is a bird watcher.
C.He is a volunteer pilot. D.He is a bird hunter.
3.What does Moullec often take photos in his flights for?
A.Recording the use of agricultural chemicals.
B.Showing serious damage caused by chemicals.
C.Describing his experiences with flying birds.
D.Capturing the beautiful views of birds and cities.
4.What can be a suitable title for the text?
A.Birdman Guides Flocks to Learn to Fly.
B.Birdman Finds Birds Disappearing.
C.Birdman Helps Flocks Safely Migrate.
D.Birdman Protects Birds From Hunters.

Cane toads, also known as bufo toads, are yet another invasive (入侵) species that has found a hospitable home in warm southern Florida. Deliberately introduced from South and Central America in the 1930s, they were supposed to control beetles damaging the sugarcane crop— that’s how they got the name “cane toads.”
Cane toads can pose a particular danger because the adult ones shoot toxin ( 毒 素 ) from their back when attacked. The tiny toads don’t carry enough toxin to be deadly yet, but big adult ones can easily send a dog into a seizure ( 疾病发作) or even kill it. The toxin is “very viscous and would stick inside the dog’s mouth,” says Steve Johnson, a wildlife ecologist at the University of Florida. Owners should try to wipe out an affected dog’s mouth and immediately take it to the vet.
Tilford started Toad Busters in 2017. The woman who lived there had nine cats, which she fed by dumping almost a bag of cat food every night. Cane toads normally eat bugs, but they are happy to eat pet food, too.
Cane toads have adapted beautifully to the Florida suburbs, so a lot of Tilford’s work also involves getting people to rethink their suburban backyard. No more cat food, for example. Pet poop (粪便) can also attract insects, which can in turn attract toads. As do lights. And toads love to breed (繁殖) in attractive pools of water, such as the lake in the affected Palm Beach Garden neighborhood. For “these larger communities that want to build these beautiful ponds and want to have houses on ponds,” Tilford said, “this is almost a pest-control service.” The cane toads aren’t going away, but they can be managed like mosquitoes or rats.
Dealing with toads amounts to an annoying thing in Florida, but they can also create more dramatic problems. In Australia—where they were also deliberately introduced in the 1930s to protect sugarcane—they are a genuine scourge (灾祸).
The issue is that Australia has no native toad species, so none of the predators (食肉动物) knew how to avoid the toxic toads. As the cane toads advanced east to west across the continent, “they left a wake of dead animals in their paths,” says Sean Doody, an ecologist at the University of South Florida at St. Petersburg who has studied cane toads in Australia. Turtles, lizards, and crocodiles just started dying out, which was good news for their prey (受害者). “If you were a small species that was previously being eaten, suddenly you’re on a honeymoon,” says Rick Shine, a biologist at Macquarie University in Sydney, Australia, who has also studied the impact of cane toads on Australian wildlife.
1.What can cane toads be described as?
A. Invasive species introduced to South America.
B. Natural enemies of beetles damaging sugarcane.
C. Dangerous species making active attacks on dogs.
D. A great threat presented to some wildlife ecologists.
2.Which might be the proper way of avoiding cane toads according to Tilford?
A. Abandon the suburban backyard.
B. Light up the backyard at night.
C. Control the number of large houses.
D. Keep pet food away from backyard.
3.What happened in Australia after cane toads being introduced?
A. Cane toads destroyed some food chains.
B. Most of the predators died of toad toxin.
C. Cane toads bred at a much slower pace.
D. Big species learned to avoid cane toads.

Black History Month is also known as the African-American History Month. It is celebrated all over the United States of America and Canada in the month of February, while in the United Kingdom it is celebrated in October. Each and every school and university conducts various activities to make the generation aware of the importance that African-American history holds in the nation. The electronic media is filled with themes in relevance to the occasion, and many activities are carried out across the country to remember the contribution made by African-American citizens in the development of this nation.
Black History Month was first started by a famous African-American historian Dr. Carter G. Woodson in the year 1926. February was chosen as the month to celebrate the African-American history because it was the birth month of two of the most highly valued people among African-Americans. These were President Abraham Lincoln, who freed the slaves, and Frederick Douglass, who was also the first vice presidential nominee (被任命者) among African-Americans. Initially, Black History Month was known as the “Negro History Week”. This was Dr. Woodson’s attempt to encourage awareness among citizens about the contribution of African-Americans towards the building of the nation. It was only in the early 1970’s that the name “Negro History Week” changed to “Black History Month”. And later, in the year 1976, the entire month of February was declared to be the National African-American History Month, or the Black History Month.
Every year, National African-American History Month is celebrated by many activities with various ideas and themes for the younger generation. In 2013, Black History Month celebrates the 50th anniversary of the March on Washington at which Martin Luther King, Jr. gave his famous speech “I have a dream”. It also marks the 150th anniversary of the Emancipation Proclamation (解放黑奴宣言). The theme for Black History Month in 2014 is “Civil Rights in America” remembering the important milestones by African-Americans and others in the battle for civil rights and equal treatment under the law.
