The largest land animal remaining on the earth, the African elephant is of much importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a giant plant-eater, it significantly shapes the forest-and-savanna (大草原) surroundings in which it lives, therefore deciding the conditions of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it both a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, as well as pulls branches off big trees. This results in numerous open spaces in not only deep tropical forests but also the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth, which attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants create open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large-hoofed plant-eaters to move around and for small-sized plant-eaters to obtain their food as well.
Scientists are worried now that the African elephant has become an endangered species. If the elephant dies out, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

Every year in America, high-school students who want to go to college take a national examination called the Scholastic Aptitude Test, or SAT in a shortened way. Their score is an important factor in determining which colleges will admit them. The Scholastic Aptitude Test measures one’s mathematical ability and use of the English language. Traditionally, the English part involved grammatical questions and paragraphs that test reading comprehension.
    But the SAT folks have added a single question, to be answered in an essay, handwritten on the spot. That’s an interesting way to test writing ability, but content aside, have you ever seen young people’s handwriting lately? Or anyone’s for that matter, in this age of computer keyboards? Students write numbers and sign their names on bank checks. They scribble class notes in what can generously be described as the written word.
Yet today’s kids are asked to write, thoughtfully and clearly, for several minutes on this SAT Test. Good luck to the text scorers who must work out difficultly the scrawl (潦草的笔迹)of young people who’ve been typing on computers since the age of three! Teachers insist that good handwriting can not only help one’s score on the SAT, but also, later on in life, impress potential employers. And don’t forget, we all have to turn to handwriting from time to time, as computers go down when power goes out.
Then how to improve the handwriting? Well, with a few simple steps you can improve your handwriting.
Position the pen. You should hold the pen between the forefinger and the thumb. You should then rest it near the first knuckle（指节）of the middle finger. The rest of your fingers should be curled （卷曲) under your hand and your hand should remain relaxed.
Evaluate your handwriting. What do you like and what you don’t like about the way you write? Make changes to your letters till you like how they look.
Take your time. Make sure that, while you are writing, you take your time. Speed is bound to make your writing messy- looking. If it is worth writing well, then take your time.
Practice. Practice it a lot; it’s not enough to do it once and hope for the best. It has to be something you work at to make great improvements.

A. math, English, reading and handwriting    B. math, grammar, reading and handwriting
