5 . Kenny Lake School in Copper Center, Alaska, is small, with about 60 students from kindergarten to high school seniors. It’s even smaller in winter when some parents home-school their children because of the long drives and slippery roads.

Jennifer Hodges is a third, fourth and fifth grade teacher. She says her three-grade class sits only at desks for 20 minutes a day. They do a lot of hands-on learning, such as raising Coho salmon (大马哈鱼) from eggs to fry (鱼苗) and then releasing them into a lake.

Coho salmon lay eggs in the fall, when many schools start. The eggs remain in the classroom about six months before they are released into lakes. After that, they live for two to four years before they lay eggs and then die shortly afterwards.

Every day, about a third of Hodges’ students travel 45 minutes by bus from the Native Village of Chitina. Many students already have the experience of fishing salmon, which is the main food in Native Alaskan communities.

“It’s really a delicate balance because we are dealing with traditions and culture of the native people,” Hodges says. “This is their land, and this is their salmon. And so we have to really be part of that.”

Students like to calculate when the salmon will turn from eggs to fry based on the temperature of the tank. To them, it’s not practicing math problems; it’s predicting the future.

“We always take a guess at when they will hatch from their eggs first,” says Liam, a student. “It takes math because you have to keep track of their temperature. I’m good at math, so I usually get it right.”

Since Hodges and her students live in such a rural area, there aren’t many field trips. But each year in May, she takes her students on the Salmon Field Trip, where they get to release the salmon they’ve raised in class. They will name the fish, then release them into the wild and never see them again. But it’s not sad; it’s the highlight of the year.

“I’m not putting up a Christmas tree this year. I just don’t have the spirit,” my husband Bill’s mom said sadly over the phone.

My husband’s parents used to have a big Christmas. There were many lights in their yard, decorations hanging from the ceiling, a big well-decorated, freshly cut tree, etc. It was amazing.

But this year would be different. With Bill’s dad passing late that November, it was understandable that his mom’s holiday spirit was nonexistent. Christmas decorating had been something husband and wife had undertaken together for over fifty years, and she simply would not do it alone.

Still, it was heartbreaking to think that not even a tree would decorate their home this year. Phone calls were made to Mom and conversations were made with her children and grandchildren in order to try to bring back her holiday spirit. Yet, it was no use.

That season, every Christmas song I heard in the stores only made me sadder as I thought of the barren (荒芜的) spot in Mom’s heart. There had to be something that could be done to bring some joy back into her life.

One afternoon, while passing a discount store, I saw many fresh green tabletop trees. They were so beautiful. Then I got an idea. I walked into the store, and selected a multi-colored string of lights and many other decorations I could find. Then I grabbed the largest tree, paid for all the things and walked home with four bags in one hand and a tree in the other.

I couldn’t imagine what I looked like, out in the cold, carrying a tree for half a mile. I only knew I felt a boost in my own heart — a boost I hoped Mom would also feel when I delivered the tree to her. And I wanted her to know that if Dad had still been alive, he would have wished her to be happy. If he had seen her unhappy, he would have been sad.

When I got home, Bill saw the tree. I told him that I would give it to Mom.

But he shook his head, saying, “I wouldn’t give this to her. She’s not going to like it…”

Just when Bill and I secretly put the tree in Mom’s yard, the door suddenly flew open.

9 . 阅读短文，在空白处填入适当的内容或括号内单词的正确形式。

Chinese researchers have recently developed an artificial intelligence (Al) model to predict the development and pattern of EI Nino events in the central Pacific Ocean.

The new model unlocks the potential for AI to improve seasonal forecasting, and     1     (offer) significant advances in climate prediction. According to the researchers, the AI model does     2     better job than traditional methods in accuracy. The researchers say a model     3     combines predictions from both the AI model and traditional methods can achieve even higher accuracy.

El Nino events in the central Pacific Ocean can have a far reaching effect     4     the global climate. The new AI model can precisely predict the sudden changes of sea surface temperatures, which     5     (believe) to be associated with central Pacific El Nino events. It also has a great impact on disaster risk reduction worldwide, as AI-driven predictions can     6     (significant) contribute to improved preparedness and mitigation (缓解) strategies. By     7     (take) advantage of the potential of Al, scientists and policymakers around the globe can work together     8     (rise) to climate-related challenges.

The research team plans to further expand the     9     (apply) of AI models in seasonal climate forecasting, with the goal of providing     10     (early) and more accurate warnings of major weather events.

10 . Flash floods can strike without warning. They can hit when you’re hiking in a river valley, walking through a canyon, or even simply driving to a remote destination. You can minimize your risk by knowing how to prepare for the worst and how to escape when a flood begins.     1    

Before heading out, check the weather report, look at any flood warnings and take them seriously.     2     Dr Steven Kugath, an outdoor recreation professor, notes that when people plan to travel a long way for a hike or canyon exploration, they often feel that they must follow through with the activity even if the weather isn’t promising. The smart thing to do is cancel the activity or move it to a safer location.

Be careful of any visual signs of danger and your surroundings while walking or hiking in a tight space.     3     Besides, always know where you are and where the nearest escape routes can be found in the event of sudden flooding.

What if, despite your preparations, you find yourself stuck in a dangerous place when flooding begins? Move to higher ground immediately, away from rivers and streams. If the situation is urgent, leave behind your possessions.     4     If you find yourself being carried away by powerful flood waters, fight as hard as you can to get to a tall tree, a street light or anything sturdy (结实) that you can hold onto until help arrives.

    5     Currents can be deceptive (误导的), and shallow, fast moving water can knock you off your feet. Moreover, don’t swim through fast-flowing water — you may get swept away or struck by an object in the water.

A．Avoid walking through moving water.

B．No bag or equipment is worth your life.

C．It takes hours for the flood waters to move away.

D．Hundreds of people die due to drowning inside their vehicles.

E．Be careful not to let your excitement drive you to take any chances.

F．Keep these tips in mind the next time you head out for an outdoor adventure.

G．The sudden arrival of dark clouds during a perfectly sunny day is one obvious sign.
