Some people think that all wild animals are dangerous. But in fact, very few of them will 1 a man if he leaves them alone. If you meet a lion or an elephant, I guess you will 2 away; but even a lion will avoid (躲避) a man if it is not very 3. Lions and tigers only kill and eat men when they have grown too 4 and too weak to catch their usual 5, such as deer and other small animals. If you see a wild elephant, perhaps you will be 6. However, elephants usually run away at once if yon don't attack them. Some animals get very frightened if they only smell a man, some 7 and look at him for a moment before they ran away, some take no notice at all but walk away 8 in another direction. Wild animals only attack 9 when they are afraid that people want to harm (伤害) their 10, or when the hunters shoot at them and make them angry.

December 25 is Christmas Day(圣诞节). Christmas is an important holiday in many countries. OnChristmas Day, most families get together for a big dinner. They give presents to each other and visit friends. The Christmas tree is an important part of the Christmas holiday. Most families buy trees. The families decorate(装饰) the tree together. Parents usually tell their children that Father Christmas comes during the night and brings presents to good children. Of course, Father Christmas isn't real. The parents of the children are really“Father Christmas”. They put the presents under the tree or into their children's stocking(长统袜)after the children go to sleep.

Last week, scientists said they discovered a new birdlike dinosaur. With feathers, a beak (鸟嘴) and long legs, it looked pretty funny. This kind of dinosaur was 3 meters (10 feet) long, and it was higher than most humans. It also had sharp claws (爪子).
Fossil hunters dug out the bones of this species in a rocky place of southwest North Dakota. The scientists nicknamed this dinosaur the "Chicken from Hell". They also gave it a more formal name: Anzu Wyliei. Anzu was a mythical (神秘的) fire-breathing bird. Wylie is the dinosaur-loving grandson of a man who supports the Carnegie Museum of Natural History in Pittsburgh, Pa. Scientists at that museum were part of the team that told the new dinosaur in a paper published on March 19 in the journal PLOS ONE. "The Anzu dinosaur is based on a surprisingly nice specimen(样品), and past digs turned up this animal," a scientist told Science News for Students.
Astronauts used to only have freeze-dried powders and semi-liquid pastes（冻干粉和半液状的糊糊）for meals. Now US scientists want to grow vegetables in mini-greenhouses on the Moon. They look forward to(provide) astronauts or space travelers with fine dinners of fresh vegetables in the future.
Paragon, a company that works with NASA, has designed the "Lunar Oasis（月亮绿洲）".
"Lunar Oasis" is a small greenhouse. It looks like a bell jar put into a 46cm-tall frame. The frame is designed to protect plants while they grow on the Moon.
They plan to send the small greenhouse into space (successful) in 2020. Scientists will put brassica（芸苔）seeds —like acabbage —in the greenhouse. Because this kind of vegetable goes from seed to flower in just 14 days, it can complete (it) life cycle in just one night on the Moon.
The Moon greenhouse has been compared to an experiment at the South Pole. The South Pole greenhouse, now in its(five) year, allows workers living in the coldest place on Earth to have (tomato), lettuces, strawberries and herbs.
"Living on the Moon seems so far away, but it is (importance) that we do this research now," said Jane Poynter, the president of Paragon.
