Wildlife Crossing Bridges
The Wildlife Bridge
In 2018，Utah built a wildlife bridge over the busy highway 1﹣80. A 4.8﹣kilometer fence was created to help guide animals to the bridge. Normally，animals take a long time to discover and begin using wildlife bridges，so experts didn't expect the bridge to get much traffic for several years. But recently，they've discovered many different kinds of animals are beginning to move by using the bridge.
The Rope Bridge
On China's Hainan Island in 2015，scientists created a bridge for Hainan gibbons （长臂猿）that are the world's most endangered primates and normally cross the forest by swinging high in the trees. But
after a 2014 typhoon，landslides caused huge gaps in the forest，which were forcing the gibbons to make dangerous jumps. Scientists created a simple and cheap rope bridge，which settled the problem.
The Eco﹣Bridge
In Uttarakhand state in India，the forest department has built a special "eco﹣bridge"，made from all﹣natural materials. It's 27.5 meters long and runs over one of the busiest highways in the area. Though the bridge is high in the trees，forest department workers hope the bridge will help smaller animals on the ground，too. Already，the bridge has gotten a lot of attention on the Internet，with many people taking photos in front of it every day.
The Park Bridge
The Phil Hardberger Park lies in San Antonio，Texas，and recently it has opened what they say is the largest wildlife bridge in the US. This bridge，unlike the others mentioned here，was built for use by both animals and humans. The park says they have already seen deer using the bridge.
（1）What has made experts feel unexpected about the Wildlife Bridge？
A.It's been completed within 2 years.
B.It's being used by animals already.

2．（10分）Linda Tutt High School opened a unique grocery store in the city of Sanger，where instead of paying for products with cash，their community can earn points which they then trade in. How do they gain points？By performing good deeds! All students，staff members and families in the school district have access to the daily goods they need to get through COVID﹣19 一free of charge.
The store is supplied through a partnership with First Refuge Ministries，Albertsons grocery store，and Texas Health Resources. It is open three days a week.
They even offer a COVID﹣friendly curbside （路边）pickup on Tuesday nights! It is meant to provide necessary daily goods for families in need. Families are automatically awarded points based on their family size，but students can help the families earn more by helping out around the school，cleaning，or getting good referrals （推荐）from their teachers. Headmaster Anthony Love
called it "the ingenious method"，compared with the traditional approaches used to make students help others.
The store is operated and managed entirely by the students. Not only are they encouraged to show others kindness，but they also have a sense of control during this uncertain time. "Many of them come from low﹣income families that need just a little extra support with food，" Anthony added.
So the store has the extra profit of giving its student employees' valuable experience. "I think this is the most exciting part of it，which they can carry with them as they graduate from high school and move on into the world，" Anthony said.
What a brilliant way to support their community! Between providing daily goods for families，giving kids experience concerned，and making their school a better place through good deeds，traditional businesses could learn a thing or two from this approach!学校食堂食品安全自查报告

3．（10分）The German ship Polarstern is normally designed to break up heavy ice. But in September，2019，the ship set sail from Norway with the goal of getting frozen into the Arctic ice cap for a year. The mission （任务）was part of a ＄155 million project known as MOSAiC，led by Germany's Alfred Wegener Institute（AWI），whose goal is to learn more about the ice that forms near the North Pole. The ice cap here isn't completely solid，and it's a collection of floes ﹣﹣﹣floating sheets of ice. As summer approaches，some of the ice melts and many floes break free.
By October，2019，the ship was frozen into the Arctic ice north of Siberia. The mission wasn't witho
ut its challenges. First and most importantly，the Polarstern had to find an ice floe that is used as its primary research base. The ice floe must be solid enough to anchor the ship and to support all the research equipment the scientists needed to use.
However，doing it proved easier said than done. Once the ship was frozen in place，the scientists had to wrestle with the dangerous polar bears that were wandering around.
Dealing with extreme cold was another challenge. They also had to face the long and dark polar night，a period during winter when the sun doesn't rise at all in the central Arctic.
In September，2020，the boat finally returned to Bremerhaven，Germany.
"We are watching the Arctic sea ice die，" said the mission's leader，Markus Rex.
The team reports that the ice shelf is full of holes，and that the ice that remains is thin and melting. Recent satellite measurements support that idea. The size of this year's ice cap is the second smallest ever recorded.
Next comes the long process of studying all the data that was collected during the last year. Thomas Krumpen，one of the scientists，said "We'll likely be busy with it over the next ten years."
The scientists hope this abundant information will help them make better predictions about climate change.
（1）What does MOSAiC try to do in the Arctic？
A.Protect the ice cap.
B.Stop the ice melting.
C.Study the ice deeply.
D.Break up heavy ice.
（2）What was the biggest challenge for the scientists on the Polarstern？
A.Finding the right floe.
B.Fighting the extreme cold.
C.Avoiding polar bears.
D.Reducing the loneliness.
（3）What is the author's attitude towards the situations of the Arctic ice？
A. Carefree.
B. Positive.
C. Tolerant.
D. Objective.
（4）Which of the following best describes the journey to the Arctic？
A. Expensive.
B. Confidential.
C. Fruitful.
D. Casual.
4．（10分）When a living thing gives off a glow（光），it's called bioluminescence. Fireflies are
a well﹣known example of bioluminescence. Many mushrooms are also bio﹣
luminescent. Fireflies and other bio﹣luminescent creatures light up thanks to chemicals inside their bodies. These chemicals are known as luciferins （荧光素），which cause a chemical reaction that gives off light.
Plants don't naturally have luciferins，so there are no naturally bio﹣luminescent plants. In the past，scientists created glowing plants by adding DNA from glowing bacteria. But the glowing effect was weak. They also created glowing plants by adding luciferins to plants. In 2017，a team at MIT was able to cause watercress plants to glow
