Ellen Kalish runs a center for rescued wild animals in New York.When a woman asked if she could treat an owl，she was happy to help.Then，the caller told her exactly where the tiny owl was hiding out.It was the Christmas tree in Rockefeller Center in New York City! Kalish said she has been helping wild animals for 20 years，but she has never heard a story like that.The rescued owl has been nicknamed “Rockefeller”．
When workers were unwrapping the tree which just arrived，one of them spotted the creature.At first the worker thought the owl might be injured.One of the workers called his wife，telling her he was bringing the owl home.He asked if she could find a place that helps wildlife animals.She called Kalish.
How did Rockefeller end up stuck in the tree in the first place Kalish offered a few ideas.He could have gone to the tree to hide and got trapped later，she said.Maybe once the tree was loaded onto a truck，the branches squished(挤压) him into the trunk.He might have been too scared to move.
Kalish met the woman who first called her at a gas station.The woman handed her a cardboard box with the owl inside.
Kalish brought Rockefeller back to the wildlife center.She said she gave him plenty of water and left two mice in the plastic pet carrier.They were gone by the next morning.Rockefeller spent most of his time at the wildlife center eating or sleeping.On Monday，he went to the vet(兽医) to get some X rays taken.He has no broken bones，Kalish added.
Rockefeller will not spend much time at the center，she said.She is preparing to release him soon.The release will be quick and quiet，she said，and she will bring a camera to take pictures of him flying away.
“I will wish him a very long and happy life，” Kalish said.

On May 9,2016，biologist Chris Kelly saw a lone bat on a bridge crossing the French Broad River outside Asheville，North Carolina.Five years later，everything wildlife biologists thought they knew about endangered gray bats in this corner of the Blue Ridge Mountains has been changed.
Kelly，a biologist with the N．C.Wildlife Resources Commission，was on the bridge doing bird work.Bats aren’t her area of expertness，so she reached out to the state’s bat experts.Joey Weber，a technician who was working for the Commission，arrived at the bridge later that day and found 19 big brown bats inhabiting in the expansion joints.But he heard many more.
That night，Weber was joined by Katherine Etchison，the Commission’s bat biologist，for an emergence count.They counted 240，but a busy schedule meant the team couldn’t return for a second emergence count until July 18.“I was very eager to get back out there because I really thought there would be something besides big brown bats.I was thinking Mexican free tailed bats，which would be a first for Buncombe County，and I was right but that wasn’t ______ ______ ________，” said Etchison.
The second emergence count recorded 1,000 bats.To learn which species used the bridge，biologists recorded the ultrasonic(超声的) sounds made by emerging bats，which are species specific.Later that night，Etchison rolled through the recorded calls，displayed vividly on her computer，and the suspected Mexican free tailed bats showed up.But，so too did something very unexpected.
She immediately texted Susan Cameron，an Asheville based biologist.Along with big brown and Mexican free tailed bats，the computer identified the calls of endangered gray bats.The discovery was confirmed the next day when Etchison，Weber，and Cameron visited the bridge at dusk—just before bat emergence—and carefully captured a bat from one of the expansion joints.The 2016 discoveries marked the first time gray bats were known to inhabit in North Carolina.
5．How did Kelly find the bat on the bridge
A．Accidentally. B．Professionally.
C．Purposefully. D．Skilfully.
6．What does the underlined phrase “the big news” refer to in the third paragraph
A．That a big brown bat was identified.
B．That Mexican free tailed bats showed up.
C．That the discovery of gray bats was confirmed.
D．That 1,000 bats were recorded.
7．How did biologists recognize the species of the bats
A．By emergence counting.
B．By recording specific sound.
C．By capturing the bats.
D．By looking through the computer.
8．Which of the following is a suitable title for the text
A．An Endangered Bat Discovery
B．A Biology Research
C．The Emergence of Bats
D．The Way of Finding Endangered Bats
C
Evidence of a worm like creature about the size of a grain of rice has been uncovered in South Australia，and researchers believe it is the oldest ancestor on the family tree that includes humans and most animals.The creature lived about 535 million years ago.____ is considered to be an evolutionary step forward for early life on Earth.
Researchers have been trying to find evidence of the common ancestor of most animals.Developing its body structure and organization successfully allowed life to move in specific，purposeful directions.This includes everything from worms and dinosaurs to amphibians(两栖动物) and humans.But for our common ancestor，they knew that fossils(化石) of the tiny，simple creatures they imagined would be nearly impossible to find because of its size and soft body.Then，they turned to fossilized burrows，dated to the Ediacaran Period，found in South Australia.
For 15 years，scientists knew the burrows were created by the creature.There was no evidence of what made the burrows and lived in them until researchers decided to take a closer look at the burrows.Geology professor Mary Droser spotted impressions shaped like ovals near the burrows.
A 3 D laser scan revealed the impressions containing evidence of a body shaped and sized like a rice grain，with a noticeable head and tail which suggested it had muscles.The muscles would have enabled the creature to move and create the burrows，like the way a worm moves.And the size of the creature matched with the size of the burrows they found.
The researchers involved in the study named the creature Ikaria wariootia.The first name translates as “meeting place” in the Adnyamathanha language.Adnyamathanha is the name of Australian people that live in the area where the fossil was found.
9．What does the underlined word “It” refer to in the first paragraph
A．A worm like creature. B．A grain of rice.
C．A family tree. D．An evolutionary step.
10．What did the researchers do during the study
A．They developed the creature in the expected way.
B．They studied a large number of worms and dinosaurs.
C．They observed the burrows close up.
D．They went back to the Ediacaran Period some years ago.
11．What inspired the scientists to explore the origin of the burrows
A．A 3 D laser scan.
B．The impressions.
C．Some good ovals.
D．More burrows.
12．What does the text mainly tell us
A．The researchers worked very hard in the burrows.
B．The worm like creature may be animals’ ancestor.
C．It is very difficult to name a new kind of creature.
D．Australian people like fossils of many creatures.

Trees have long played a special role in all aspects of human life.In ancient times，trees provided a place for humans to take shelter from storms，heat and even enemies.Today，the importance of trees continues to increase. 1
Trees provide the necessary oxygen to breathe.Many industrial and development activities add huge quantities of carbon dioxide to the environment.Trees absorb carbon dioxide and in turn release fresh oxygen in the environment. 2 Thus，they are the most important contributors in maintaining the environmental balance.
Trees can prevent soil erosion(侵蚀) and clean soil.Trees bind(捆绑) the soil of the earth tightly. 3 They are highly beneficial for preventing soil erosion.Besides，poisonous chemicals and pollutants from various factories enter into the soil，thus causing soil pollution.Trees have the ability to store them or change them into less harmful forms.
4 Trees satisfy the need of fuel for cooking in many areas around the world.Trees also provide wood for furniture and hundreds of household items.Wood pulp(浆) is used for making paper in industries.Also，trees produce a number of fruits and nuts which are sold at market.Some trees are even used to make medicines.
Trees provide life to birds and insects. 5 Insects get their food in the form of seeds，buds，and fruits.Thus trees are the most important supporters of life.
A．This lowers global warming.
B．Trees are of commercial importance.
C．This increases the drying effect on the soil.
D．More benefits of trees are being discovered.
E．They give them food，shelter，cover，and nest sites.
F．Trees provide wood for making furniture and paper.
G．Therefore，fast flowing water or heavy wind is unable to take away soil with it.
