Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air， water and sunlight. Animals and man cannot make food from air， water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us. If you look carefully at the plants around you， you will find that there are two kinds of plants： flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed， some have two， three or four， and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）。 Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places， they usually grow into new plants.

It has been more than twenty years since pioneering British computer programmer, Sir Tim Berners Lee, created the World Wide Web. But could he have ever imagined how much the web would change our lives? And would he approve of how some British students are taking advantage of his invention?
Universities and exam boards around the UK are becoming increasingly concerned with the rising number of cases of plagiarism, many of which are facilitated (助长) by the Internet access.
In the UK most school and university students complete coursework throughout the academic year which contributes toward their final mark. In many cases coursework makes up the main part of the qualification. Since coursework is completed in the students’ own time it cannot be monitored by teachers in the same way as an exam.
Derec Stockley, director of examinations in the UK, explains, “Plagiarism affects coursework more than anything else, and in the cases that come to our attention, more and more are linked to the Internet.”
At a university level recent reports suggest that plagiarism has evolved from separate cases of individual cheating to systematic and even commercial operation. Students can now pay for bespoke essays to be written for them by experts.
It is estimated that the market in online plagiarism is now worth 200 million pounds a year. Every month more and more websites offering to write student’s essays for them appear on the Internet.
Barclay Littlewood, owner of Degree Essays UK employs 3,500 specialist writers and charges between 120 pounds and 4,000 pounds per essay. However, Mr. Littlewood refutes the accusation that he is helping students to cheat.

Like all animal species, plant species must spread their offspring to suitable areas where they can grow and pass on their parents’ genes. Young animals generally spread by walking or flying. Because plants don’t have that ability, they must somehow hitchhike(搭车). Some plant seeds scatter by blowing in the wind or floating on water. Many other plant species, though, trick an animal into carrying their seeds. How do they do this? They enclose the seeds within a tasty fruit and advertise the fruit’s ripeness by its colour or smell. The hungry animal collects and swallows the fruit, walks or flies off, and later spits out the seeds somewhere far from its parent tree. Seeds can thereby be carried for thousands of miles. It may surprise you to learn that plant seeds can resist digestion. In fact, some seeds actually require passage through an animal’s body before they can grow.
Wild strawberries offer a good example of hitchhiking tactics. When strawberry seeds are still young and not yet ready to be planted, the surrounding fruit is green, sour and hard. When the seeds finally mature, the berries turn red, sweet, and tender. The change in the berries’ colour serves as a signal to birds which then eat the strawberries, fly off, and eventually spit out the seeds.
Naturally, strawberry plants didn’t set out with a conscious intention of attracting birds only when their seeds were ready to be dispersed. Nor did birds set out with the intent of planting strawberries. Rather, strawberry plants evolved through natural selection. The sweeter and redder the final strawberry, the more birds spread its ripe seeds; the greener and more sour the young strawberry, the fewer birds destroyed the seeds by eating berries before the seeds were ready.
46．What does the underlined word “dispersed” in the third paragraph mean?
A．spreadB．eaten
C．born D．planted
47．For plants, which of the following is NOT a way of spreading their offspring to suitable areas?
A．Hitchhiking. B．Blowing in the wind.
C．Floating on water.D．Tracking an animal.
48．Which strategy does the example of wild strawberries describe?
A．The conscious intent of attracting birds. B．Spreading by walking.
C．Spreading by flying.D．The strategy of taking a lift.
49．Why does the author describe how strawberry seeds are spread?
A．To show plants are good at adapting to the environment. .
B．To show strawberry’s special way.
C．To show the plant has different ways of spreading seeds.
D．To show the mystery of plant.
50．What’s the passage mainly about?
A．How animals disperse offspring.B．How plants disperse their offspring.
C．Plant evolution.D．Plants’ hitchhiking on animals.

Like other student athletes, Ray Ray McElrathbey deals with schoolwork, practice and games. But after a long day of studying and working out on the football field, the Clemson University player can’t relax with friends. Ray Ray has to make sure his 11-year-old brother, Fahmarr, gets a good dinner, does his homework and goes to bed.
Since taking responsibility for Fahmarr this August, “I’ve aged dramatically, ” said Ray Ray. “I can’t be running around at all hours, making 19-year-old decisions.” Ray Ray has temporary custody (监护权) of Fahamrr. Their mother struggles with drug addiction, and they are not in touch with their dad. Ray Ray didn’t want to see his brother go into foster care(收养), where both of them have spent time. The brothers now live together in an apartment near the campus in Clemson, South Carolina.
Clemson Tigers fans aren’t the only people rooting for Ray Ray. Sports Illustrated, ESPN and ABC News have featured the story of the brothers.
