【推荐2】Plans to bring wild tigers back to their original home , their historical range(历史分布范围） in the Ili­Balkhash region, have been announced by Kazakhstan( 哈萨克斯坦 )   and an agreement with World Wide Fund for Nature (WWF) to conduct a tiger reintroduction program has been signed . “It will not only bring wild tigers back to their original home, but also protect the unique ecosystem of the Ili­Balkhash region，” said Askar Myrzakhmetov, the Minister of Agriculture of the Republic of Kazakhstan.

If successful, Kazakhstan will be the first country in the world to bring wild tigers back to an entire region where they have died out for nearly half a century. Tiger reintroduction projects have only been achieved within national borders and in areas that are considered current tiger habitats . Kazakhstan's tiger reintroduction program is unique and it badly requires the restoration of a vast forest that is part of the wild tiger's historical range.

Since the beginning of the 20th century, wild tigers have lost over 90 per cent of their historical range. Wild tigers have completely disappeared from the region since the late 1940s, due to the loss of habitat. To prepare for the return of wild tigers, on 1st January 2018 Kazakhstan will set up a new nature reserve in the southwestern Ili­Balkhash, in order to restore the unique forest habitat. This will include the protection of existing wildlife, and reintroducing important prey ( 猎物 ), such as the endangered wild Bactrian deer（中亚红鹿).

Restoring tigers will also help protect Lake Balkhash and prevent it from repeating the fate of the Aral Sea, formerly the world's fourth largest lake and now 10 percent of its original size. “The hard work remains ahead of us. We have to spare no effort to make this region ready for tigers and involve all the relevant people to make this happen. That means dealing with illegal activities, having these people who govern parks be well­trained and equipped, increasing prey populations and involving local communities，” said Ekaterina Vorobyeva, Director of the WWF program.

Cows have four stomachs, one of which helps break down the grass into something that the cow’s body can use. But when this happens, much methane (甲烷), which is the world’s second   worst greenhouse gas, will be produced. The methane comes out of a cow’s body mainly as burps (打嗝).

Recently, the researchers from the University of California, Davis studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood (罩子), which allowed the scientists to know how much methane the cows were giving off. They used some seaweed, which they mixed with the cows’ food.

The results were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given, but even the worst-polluting cows produced 33% less methane.

Over the five months, the scientists didn’t see any signs that the cows produced more methane again. What’s more, the cows that were fed seaweed put on just as much weight as the other cows, but they didn’t need as much food.

But there are still some big problems with the idea of feeding cows seaweed. For one thing, there’s not enough seaweed to feed all of the cows in the world. So farmers would have to find a way to grow lots of seaweed. A bigger problem is that for most of their lives, cows live in the fields, where they eat grass. That means there’s no chance to feed them seaweed every day.

Still, it’s very good news that something as simple as feeding cows seaweed can help cut down on some of the pollution causing the increasing temperature (温度).

【推荐3】In the town of Willowbrook, two friends named Emma and Liam shared an intimate bond. They were inseparable and spent every moment together, laughing, exploring, and creating unforgettable memories.

One cold winter morning, Emma woke up with a stuffy nose and a sore throat. She tried to brave it and get ready for school, but her body felt weak and achy. Unwillingly, she called Liam to let him know she couldn’t make it to school that day.

Liam was concerned when he heard the tiredness in Emma’s voice. “Don’t worry, Em. I’ll take care of everything at school for you,” he assured her. Feeling grateful for Liam’s understanding, Emma forced a smile and replied, “Thank you, Liam. You’re the best friend anyone could ask for.”

After school, Liam hurried to Emma’s house, carrying a meal he had prepared for her. He knocked on the door, and Emma’s mother welcomed him with a warm smile. “Oh, Liam, you’re such a thoughtful friend,” she said.

“I brought some soup and tea for Emma. I hope it will make her feel better,” Liam replied, some concern in his eyes. Entering Emma’s room, Liam found her pale but relieved to see him. “I brought some comfort food to cheer you up,” he said, setting the food on her bedside table.

Emma’s eyes lit up, and she smiled weakly. “Thank you. This means the world to me,” she whispered. Sitting by her side, Liam kept her company, chatting softly and making her laugh. The warmth of their friendship enveloped the room, bringing a feeling of comfort to Emma’s tired soul.

As Emma regained her strength, she realized how lucky she was to have a friend like Liam. Their friendship grew stronger with each passing day, and from that moment on, they knew they would be there for each other through thick and thin.
