What does the word “they” in paragraph 2 refer to?

The countryside of Britain is well known for its beauty and many contrasts: its bare mountains and moorland, its lakes, rivers and woods, and its long, often wild coastline. Many of the most beautiful areas are national parks and are protected from development. When British people think of the countryside they think of farmland, as well as open spaces. They imagine cows or sheep in green fields enclosed by hedges or stone walls, and fields of wheat and barley. Most farmland is privately owned but is crossed by a network of public footpaths. Many people associate the countryside with peace and relaxation. They spend their free time walking or cycling there, or go to the country for a picnic or a pub lunch. In summer people go to fruit farms and pick strawberries and other fruit. Only a few people who live in the country work on farms. Many commute to work in towns. Many others dream of living in the country, where they believe they would have a better and healthier lifestyle. The countryside faces many threats. Some are associated with modern farming practices, and the use of chemicals harmful to plants and wildlife. Land is also needed for new houses. The green belt, an area of land around many cities, is under increasing pressure. Plans to build new roads are strongly opposed by organizations trying to protect the countryside. Protesters set up camps to prevent, or at least delay, the building work. America has many areas of wild and beautiful scenery, and there are many areas, especially in the West in states like Montana and Wyoming, where few people live. In the New England states, such as Vermont and New Hampshire, it is common to see small farms surrounded by hills and green areas. In Ohio, Indiana, Illinois and other Midwestern states, fields of corn or wheat reach to the horizon and there are many miles between towns. Only about 20% of Americans live outside cities and towns. Life may be difficult for people who live in the country. Services like hospitals and schools may be further away and going shopping can mean driving long distances. Some people even have to drive from their homes to the main road where their mail is left in a box. In spite of the disadvantages, many people who live in the country say that they like the safe, clean, attractive environment. But their children often move to a town or city as soon as they can. As in Britain, Americans like to go out to the country at weekends. Some people go on camping or fishing trips, others go hiking in national parks.

We can see from the passage that in the countryside of Britain ______.

Orchids are unique in having the most highly developed of all blossoms, in which the usual male and female reproductive organs are fused in a single structure called the column. The column is designed so that a single pollination will fertilize hundreds of thousands, and in some cases millions, of seeds, so microscopic and light they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of the petals is called the labellum, or lip. It is often dramatically marked as an unmistakable landing strip to attract the specific insect the orchid has chosen as its pollinator. To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times. Once the right insect has been attracted, some orchids present all sorts of one-way obstacle courses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampant crossbreeding in the wild, assuring the survival of species as discrete identities.

At the same time they have made themselves irresistible to collectors. How many orchid seeds are typically pollinated at one time?

Mickey Mantle was one of the greatest baseball players of all time. He played for the New York Yankees in their years of glory. From the time Mantle began to play professionally in 1951 to his last year in 1968, baseball was the most popular game in the United States. For many people, Mantle symbolized the hope, prosperity, and confidence of America at that time. Mantle was a fast and powerful player, a “switch-hitter” who could bat both right-handed and lefthanded. He won game after game, one World Series championship after another, for his team. He was a wonderful athlete, but this alone cannot explain America’s fascination with him. Perhaps it was because he was a handsome, red-haired country boy, the son of a poor miner from Oklahoma. His career, from the lead mines of the West to the heights of success and fame, was a fairy-tale version of the American dream. Or perhaps it was because America always loves a “natural”: a person who wins without seeming to try, whose talent appears to come from an inner grace. That was Mickey Mantle. But like many celebrities, Mickey Mantle had a private life that was full of problems. He played without complaint despite constant pain from injuries. He lived to fulfill his father’s dreams and drank to forget his father’s early death. It was a terrible addiction that finally destroyed his body. It gave him cirrhosis of the liver and accelerated the advance of liver cancer. Even when Mickey Mantle had turned away from his old life and warned young people not to follow his example, the destructive process could not be stopped. Despite a liver transplant operation that had all those who loved and admired him hoping for a recovery, Mickey Mantle died of cancer at the age of 63.

What is the main idea of the passage?

Marianne Moore (1887-1972) once said that her writing could be called poetry only because there was no other name for it. Indeed her poems appear to be extremely compressed essays that happen to be printed in jagged lines on the page. Her subjects were varied: animals, laborers, artists, and the craft of poetry. From her general reading came quotations that she found striking or insightful. She included these in her poems, scrupulously enclosed in quotation marks, and sometimes identified in footnotes. Of this practice, she wrote, "Why many quotation marks?" I am asked ... When a thing has been so well that it could not be said better, why paraphrase it? Hence, my writing is, if not a cabinet of fossils, a kind of collection of flies in amber." Close observation and concentration on detail and the methods of her poetry. Marianne Moore grew up in Kirkwood, Missouri, near St. Lois. After graduation from Bryn Mawr College in 1909, she taught commercial subjects at the Indian School in Carlisle, Pennsylvania. Later she became a librarian in New York City. During the 1920’s she was editor of The Dial, an important literary magazine of the period. She lived quietly all her life, mostly in Brooklyn, New York. She spent a lot of time at the Bronx Zoo, fascinated by animals. Her admiration of the Brooklyn Dodgers-before the team moved to Los Angeles-was widely known. Her first book of poems was published in London in 1921 by a group of friends associated with the Imagist movement. From that time on her poetry has been read with interest by succeeding generations of poets and readers. In 1952 she was awarded the Pulitzer Prize for her Collected Poems. She wrote that she did not write poetry for money or fame. To earn a living is needful, but it can be done in routine ways. One writes because one has a burning desire to objectify what it is indispensable to one's happiness to express.
