【推荐2】Doctors across the world tell us it is necessary to eat lots of vegetables to keep the heart healthy. But a new study in February, 2022 suggested eating a lot of vegetables may not greatly cut down the risk of heart problems.

The study is from universities in Oxford and Hong Kong, China. Almost 400,000 people took part in it. They answered questions about their lifestyle, food, and what raw (生的) and cooked vegetables they ate. The study actually found that the risk of dying from heart problems was around 15% lower for those eating the most vegetables, especially raw vegetables.

However, scientists explained that many other factors (因素) also have something to do with this 15% drop. These factors may affect (影响) our health just as much as vegetables. These include other things we eat, how much exercise we get, where we live and whether we smoke or drink. Lead researcher Dr. Qi Feng from the University of Oxford said, “Our large study did not find clear evidence (证据) that how many vegetables you take can cut down chances of heart problems.”

But does it mean that eating vegetables is futile? No. Many other scientists advise that people should still eat at least five kinds of fruit and vegetables every day. That’s because vegetables are important for keeping good health and reducing (减少) the risk of serious illnesses.

1. How many people answered questions for the study?

A．About 4,000.

B．About 1,000.

C．About 100,000.

D．About 400,000.

【推荐2】The Amazon （亚马逊） rainforest is in South America. It’s about half the size of China! The Amazon River runs through the rainforest. It’s the world’s second longest river.

According to a new study, the Amazon rainforest may become grassland（草原）in a few years.

The Amazon is the world’s biggest rainforest. Climate （气候）, the rainforest can fix itself. But now, it feels too “tired” to get better. The trees may die and the rainforest could turn into a hot, dry grassland.

Why is the Amazon “sick”?

The Amazon is one of the world’s wettest places. But since 2005, three hot dry weathers have hit the rainforest. They were caused by climate change. The trees don’t have enough water to grow. What’s worse, as they become dry, people cut down rainforest trees for wood. They turn the forest into the farmland. All these activities have caused about 17 percent of the rainforest to disappear.

What will happen if we lose it?

If the Amazon “dies”, there will be more CO₂（二氧化碳） and our Earth will become even hotter. The Amazon is also home to many animals and plants. Many of them can’t live anywhere else. They will just disappear too.

判断正（A）误（B）。
1. The Amazon River is the world’s longest river.
2. China is smaller than the Amazon rainforest.
3. The Amazon rainforest will turn into grassland because of itself.
4. When the Amazon was a wet place, the trees there couldn’t catch fire easily.
5. If we lose the Amazon rainforest, many animals will die too.

【推荐2】Crested ibises (朱鹮) are one of the oldest bird species (物种) on Earth. It is believed that they have been around for 60 million years. They were once common in Asia. But in the 1960s, they began to disappear because of pollution and other human activities. In 1981, Chinese scientists found seven of them in the wild in Yangxian, Shaanxi Province. They were believed to be the last ones in the world. But now, they have been saved from extinction.

Researchers say its population has risen to more than 5, 000 around the world. There are 3, 000 crested ibises in Yangxian alone. The birds’ survival (幸存) is because of China’s early protection efforts, according to Zhang Yueming, an expert who helps protect the birds in Yangxian.

On the fourth day after finding the ibises, the local government put up a lot of notices to protect the birds. Then, it stopped people from cutting down trees. Later, it set up the Qinling No. 1 protection station and sent four people to look after the birds day and night. During the daytime, they watched and recorded the birds’ habits and conditions. At night, their job was to keep them safe.

To help the ibises have more babies, a rescue and breeding center (救助和繁育中心) was set up in 1990. At the center, crested ibises are fed by people and can receive timely help when they are sick or hurt. China’s protection of crested ibises is an example in the world's history of protecting endangered wildlife.

【推荐3】When people think of tigers, they think they are strong and dangerous. But now, the big animal needs our help. There were once eight kinds of tigers in the world, but three died out during the 20th century. In the last 70 years, the number of Siberian tigers has gone from 300 to less than 22. The Siberian tiger has been in danger of dying out completely. If the government doesn’t make any efforts, it’s quite possible that there will be no more Siberian tigers in China in twenty years.

       WWF has started a program recently. The purpose is to save wild tigers and put an end to tiger hunting and killing. China, together with twelve other countries has joined in. Wild animals, such as red deer and wild pigs, are the main food of the tigers. The hunting of these animals is bad for tigers. So the most important thing is to protect the animals that tigers eat. We need to call on more people to stop eating and hunting wild animals.
