8 . Rainforests are home to a rich variety of medicinal plants, food, birds and animals. Can you believe that a single bush(灌木丛)in the Amazon may have more species of ants than the whole of Britain! About 480 varieties of trees may be found in just one hectare of rainforest.
Rainforests are the lungs of the planet-storing vast quantities of carbon dioxide and producing a significant amount of the world's oxygen. Rainforests have their own perfect system for ensuring their own survival; the tall trees make a canopy(树冠层)of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds.
Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is the plants' way to prevent the spread of any tree diseases and make life more difficult for leaf-eating insects like caterpillars. To survive in the forest, animals must climb, jump or fly across the gaps. The ground floor of the forest is not all tangled leaves and bushes, like in films, but is actually fairly clear. It is where dead leaves turn into food for the trees and other forest life.
They are not called rainforests for nothing! Rainforests can generate 75%of their own rain. At least 80 inches of rain a year is normal-and in some areas there may be as much as 430 inches of rain annually. This is real rain-your umbrella may protect you in a shower, but it won't keep you dry if there is a full rainstorm. In just two hours, streams can rise ten to twenty feet. The humidity(湿气)of large rainforests contributes to the formation of rainclouds that may travel to other countries in need of rain.

10 . An international group of coffee experts has considered Ethiopia’s coffee as the best in the world.Coffee is a top export (出口物) of the country. But at home, it is seen as national pride. Ethiopians feel good about their coffee, and enjoying a drink with friends is a long tradition.
Some people say the climate produces quality beans. Morton Wennersgarrd is a coffee importer. He said, “Ethiopia has different ancient types of coffee. They are planted in places with perfect soil, perfect altitude (海拔), and climates that are really suitable for coffee processing.”
Finding the best quality beans is often an issue of taste. The process is known as cupping — tasting and comparing coffee from different roasted beans, grading and then pricing them. But before international experts come to taste, coffee beans are studied in small coffee laboratories. Helen Assefa, a lab technician, describes the process, “When the coffee comes to the lab, we assess (评价) its quality first by recording the details.Then we weigh the moisture (水分) level and we examine the beans for analysis. After that we grind (磨碎) the coffee beans and taste the samples. In the end, we check for defective (有瑕疵的) beans.” Mubarik Abaoli is a lab worker.He says that testing is a very difficult and long process. “We select out the defects by hand. And we select out the defect according to the defect types.”
Ethiopia has got a lot of money by exporting coffee to more than 120 countries. The country has an export revenue (税收) of more than 840 million a year. But not all the best coffee leaves Ethiopia. Forty percent of the coffee grown in the country stays there. It remains an important part of everyday life at work, at home and at ceremonies.
