2 . What foods do you use to celebrate with your family? Do you eat something special on your birthday or holidays? Among the Hopi people, many foods for special celebrations are made from corn.
The Hopi people are Native Americans who live in Black Mesa, Arizona, USA. They grow special types of corn with long roots (根), which help the corn reach water in the ground in the hot and dry desert (沙漠).
The Hopi use each color of corn for something different. For example, blue corn is used to make some traditional Hopi foods. Piki is one Hopi food made with blue com. It is like a paper-thin, rolled pancake.

4 . A Fish and Wildlife Service proposal would protect the whitebark pine as an endangered species. Whitebark pines can live for up to 1,000 years and grow at elevations (海拔) as high as 12,000 feet. Environmentalists had requested the government in 1991 and again in 2008 to protect the trees. A nonnative fungus (真菌) has been killing whitebark pines for a century. More recently, the trees have proved vulnerable (易受伤的) to tiny insects that have killed large areas of forest.
The whitebark pines have almost disappeared in some areas, including the eastern edge of Yellowstone National Park, where they are a source of food for threatened grizzly bears (灰熊). This makes the government’s declaration of the Yellowstone area’s grizzly bears as a restored species a lie.
After being blamed for not taking steps to protect the trees, wildlife officials in 2011 admitted that whitebark pines needed protection, but they didn’t act rapidly, saying other species faced more immediate threats.
A lawyer for the Natural Resources Defense Council, which made the formal request for protection in 2008, expressed his disappointment that it took so long but said the proposal was still worth celebrating.
The government’s proposal described the threats to the trees as immediate and said the whitebark pines were one of many plants expected to be harmed as climate change moves faster than they can adapt. “Whitebark pines survive at high elevations already, so there is little remaining habitat in many areas for the species to move to higher elevations in response to warmer temperatures,” Fish and Wildlife Service officials wrote.
Government officials are working with researchers and private groups on plans to gather seed from trees, grow them in greenhouses and then plant them back on the landscape, according to Fish and Wildlife Service biologist Amy Nicholas. A proposal of that nationwide restoration is expected by the end of this year. “We do have options to restore this species,” Nicholas said.

5 . Imagine you are on a beautiful tropical beach. The blue water shines in the sun, and the sand is warm under your feet. You notice a small fruit in the sand. It looks like a little green apple. You pick it up and smell it... it smells sweet. But whatever you do. Don’t take a bite!
This is the fruit of the manchineel tree. It is the most poisonous tree in America. You can find it in Florida, as well as in the Caribbean, Mexico, and Central America.
If you were to eat the fruit, it would taste delicious. But then your mouth would start to burn. Your throat would tighten and make it difficult to breathe. You could even die.
The fruit isn’t the only risky part of the manchineel tree. The tree is full of milky white sap. Sap is a liquid that flows through a plant, like blood flows through a person. The manchineel’s sap is hazardous. If it gets on your skin, it will cause painful blisters. So don’t try to cut down these trees, because you could get sap all over you!
And if you try to burn manchineel wood, the smoke will choke and blind you.
Manchineel trees are dangerous, but they’re also an important part of the environments where they grow. Manchineels protect beaches with their strong roots. The roots help stop sand and soil from washing away. This is good for the plants, animals, and people living nearby. There aren’t many manchineel trees left in the world. So even though they’re harmful, people are trying to protect them. Still, if you see one, stay away!

9 . Looking for a big-leafed houseplant that will make a statement in your room and decorate yourhome? If so, then you’ve come to the right place!
Peace Lily
Extremely easy to look after, this popular, flowering plant is very tolerant and undemanding. It is a beloved houseplant for its large, glossy oval leaves and unusual white spoon-shaped flowers. Typically blooming in the spring, this lovely plant can effectively brighten up a living space.
African Mask Plant
This indoor plant is a smaller plant with large dark green leaves that are shaped like a heart. Native to tropical (热带的) parts of Africa, it prefers high heat and high humidity. That can be somewhat a tricky task for the average plant owner to achieve in their home, who is likely to have trouble duplicating (复制) these steamy conditions.
Snake plant
Commonly referred to as mother-in-law’s tongue, it is one of the easiest houseplants to take care of. With tall, twisting sword-shaped leaves that grow upright, it has air-purifying capabilities and can merrily grow in almost dark corners of the house. But the plant is poisonous to dogs and cats, so it’s wise to keep this plant away from them, if your pets are plant chewers.
Kentia Palm
Caring for the Kentia Palm plant is very straightforward, which can be neglected for weeks at a time. Quite enjoying a bit of shade, it has big leaves that grow from a narrow base and is great for filling a corner without taking up much floor-space. Place it in front of a blank wall, and its archingfronds (大型复叶) will cast beautiful shadows.
