    Floating on the surface of the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see. They move about lazily with the currents, providing a basic food for many larger animals. Plankton has been described as the equivalent (相等的东西) of the grasses that grow on dry land, and the comparison is an appropriate one. In potential food value, however, plankton far outweighs that of land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates(碳水化合物) each year, the sea's plankton produces more than twice as much.

    Despite its enormous food potential, little effort was made until recently to farm plankton as we farm grasses on land. Now scientists have at last begun to study this possibility, especially as the sea's resources appear even more important as a means of feeding an expanding world population.

    No one yet has seriously suggested that “planktonburgers” may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among scientists.

    One type of plankton that seems to have great harvest possibilities is a tiny creature called krill(磷虾). Growing to two or three inches long, krill are a major food source for the giant blue whale, the largest animal ever to live on the Earth. Realizing that this whale may grow 100 feet and weigh about 150 tons, it is not surprising that each one swallows more than one ton of krill daily.

    Krill swim about just below the surface in huge schools sometimes wide, mainly in the cold Antarctic. Because of their pink color, they often appear as an entire reddish mass when viewed from a ship or from the air. Krill are very high in food value. If krill can feed such huge creatures as whales, many scientists reason, they must certainly be competitors among possible new food sources for humans.

(1)、Which of the following correctly describes plankton?
A、It has a higher food value than grasses. B、It is food for most small sea animals. C、It can grow on dry land as well. D、It grows up in the deep water.
(2)、Why does the author mention "planktonburgers" in Paragraph 3?
A、To show scientists' interest in plankton. B、To describe the appearance of plankton. C、To question the food potential of plankton. D、To suggest plankton as a possible food source.
(3)、According to Paragraph 4, the blue whale___________.
A、feeds mainly on krill. B、can grow up to 150 feet. C、suffers from lack of food. D、was born two or three inches long.
(4)、Which of the following is TURE about krill?
A、They mainly live in the Arcitc. B、They are of great value to humans. C、They are the smallest sea animals. D、They come in many different colors.

    Wild animals are our friends, but many of them are getting fewer and fewer. We should try to protect them. The four animals below are now in danger.

     Tibetan Antelopes

    Tibetan antelopes are medium - sized animals. They mainly feed on grass. They are usually found in groups of about 20. They are killed for their wool, which is warm, soft and fine and can be made into expensive clothes. Although people can get the wool without killing the animals, people simply kill them before taking the wool. The number of them is dropping year by year. There are less than 75,000 Tibetan antelopes left in the world, down from a million 50 years ago.

    Golden Monkeys

    Golden monkeys are mainly found in Sichuan, Gansu, Shanxi provinces and Shengnongjia mountainous area of Hubei Province. Golden monkeys have golden - orange fur. They move around in the daytime, usually in groups of as many as 100 to 200 heads, or 20 to 30 heads. They feed on fruits and young leaves of bamboos. But people are destroying the environment where they live. Trees and bamboos are disappearing, so golden monkeys have less and less to eat.

    Elephants

    Elephants are very big and strong. They are bigger than any other animals on land. They are grey and have long trunks and tusks. They have poor eyesight, but very good hearing and smell. They can lift heavy things and break down branches with their trunks. Elephants are very friendly towards each other and towards their neighbours. Normally, they live in a group for many years. Young male elephants do not leave the group until they are about 12 years old. Now, there are very few elephants in the world. The number of them is becoming smaller and smaller because their living areas are used for fanning. Also, people hunt them for their tusks.

    Wolves

Wolves are not very big. They have grey fur. Solves have very good eyesight, hearing and smell. Wolves' food is various. They eat animals, insects and snails. They are friendly to each other and never attack people. They do not kill for fun. Wolves are in danger, too. They are losing their living areas because people cut down forests. Soon they will have no home or food.

    Crown shyness(树冠羞避) is a mysterious natural phenomenon in which the crowns of some tree species do not touch each other, but get separated by a gap clearly visible from ground level. The effect usually occurs between trees of the same species, but has also been observed between trees of different species.

    There are many theories going around, most of which make sense, but no one has been able to prove without the shadow of a doubt why some trees avoid touching each other.

    In his 1955 book Growth Habits of the Eucalypts, Australian forester M.R. Jacobs writes that the growing tips of the trees are sensitive to abrasion(擦伤), which results in crown shyness phenomenon. This theory was also supported by Dr. Miguel Franco. Some experiments have shown that if trees displaying crown shyness are artificially prevented from swinging in the wind and touching each other, they gradually fill up the gaps between them.

    But while the above theory is arguably the most widespread, it's certainly not the only one. Some scientists have suggested that crown shyness is a mechanism to stop the spreading of leaf-eating insects. These pests have been known to work together and create structures that extend up to 10 cm off of tree branches in order to reach other plants, so the gaps are the trees' natural defense method.

    One Malaysian scholar studied many trees, but found no traces of abrasions, despite their clear crown shyness. Instead, he suggests that the growing tips of the trees were sensitive to light levels and stopped growing when they got too close to other trees. Plants are able to sense how close they are to other plants and in order to get more light, they give off some chemical element to stop other trees from growing too close.

    Whatever the reason, one thing is for sure: plants are more intelligent than people used to think.
