Gold used in jewelry is mixed with harder metals to add strength and durability. The metals added can also be used to change gold" s color， giving it a fashionable rose or white tint， or to lighten or darken the natural yellow， tone of pure gold.Mixtures like these， of less costly metals with more valuable ones， are called alloys. Copper and silver are the most common metals mixed with gold to make yellow gold jewelry. White gold is usually made with an alloy of gold and nickel.
The measure of gold" s purity is called a karat. The higher the karat rating，the higher the amount of pure gold: 24 karat is pure gold，18 karat is 75% pure gold，14 karat is 58.5% pure gold， and 9 karat is 37.5% pure gold. All other things being equal ，the higher the percentage of pure gold used in the alloy，the more valuable and expensive the jewelry wll be.
Gold jewelry pieces are usually stamped with a marking to identify the karat amount. While gold that is 24K is too soft for jewelry，18K，14K and 9K gold are all appropriate for jewelry， and they all make pieces that look great and wear beautifully.
Which of the following statements best.captures the main idea of this passage？ 查看材料
A.Although gold is very valuable，it is also very expensive.
B.Gold jewelry is stamped with its karat ，weight.
C.Gold jewelry is made using alloys.
D.Colored gold is more valuable than white gold.

The crowd stirred and whispered in awe as， on the stage， the horse slowly tapped out the beat．Everyone became tense and quiet as the number of taps neared the correct answer to the horse trainer"s question．After the final tap， the horse paused， seemed to look around and stopped．The crowd went wild !
The horse"s name was Clever Hans， the Educated Horse， and was featured in a vaudeville（杂耍）act in the early 1900s， in Europe．When asked a complicated mathematical question by his owner，Clever Hans would tap out the correct answer with his hooves．For example， if the answer was sixty-eight， Hans would tap out six with his left hoof and eight with his right hoof．Even more remarkable，the owner would leave the room after asking the question， so there could be no secret signal between owner and horse．A mere animal seemed to be accomplishing a highly technical skill of man"s!
It wasn"t until years later that the secret of the trick was revealed．The owner had trained Clever Hans to respond to slight signals．The horse became so sensitive that he learned when to stop from the crowd"s reaction．Members of the audience would start involuntarily， or give some unconscious signal，when Hans reached the right answer．Modern scientists now warn against the Clever Hans syndrome（综合征 ）， whereby researchers unconsciously give clues to their animal subjects about the actions they like to see performed!
This passage is mainly about________． 查看材料
A.animal intelligence
B.mathematical skills
C.Clever Hans
D.unconscious behavior

Many of the problems we face today are not so new as we think they are. And some of our modern solutions are not so new， either. The problem of energy shortages and the solution of using solar energy go back at least to early Greek cultures. The climate in the coastal areas of Greece 2，500 years ago was characterized by cool winters， much as it is today. At that time， the Greeks heated their homes with small， charcoal-burning heaters. In other words， wood （which is used to make charcoal） was their primary source of energy.However， by the fifth century BC fuel shortages had become common because， in many parts of Greece， the firewood in the forests had been depleted. Once the supply of firewood from the local forests ran out， people began to use the wood from olive groves as fuel. But this solution had its own problem. It reduced the olive crop， a valuable resource to the Greeks. By the fourth century BC， the city of Athens banned the use of olive wood for fuel. Wood had to be imported from farther and farther away， making it more difficult to obtain and more expensive to use. About this time the Greeks began to build their houses facing south， so that the low sun in winter could penetrate and help heat the interiors. Excavations of ancient Greek cities suggest that large areas were planned so that individual homes could take maximum advantage of passive solar energy.
The word "depleted" means________. 查看材料
A.damaged
B.stolen
C.used up
D.discovered

Have you ever heard of a flower whose seeds are carried and spread by elephants？ The rafflesia， a rare blossom， is very unusual. Found in the rain forests of Sumatra， the rafflesia is the world"s largest flower， measuring three feet in diameter!
This giant flower is a parasite——it needs another plant to live on. It lacks the structures needed to survive alone， The rafflesia has no stem or leaves. It is all flower. It attaches itself to the roots of other plants and sucks their juices. The flower"s favorite home is the root of the vine， which grows above ground.
The rafflesia seems to burst right out of the forest floor. Its blossom weighs fifteen pounds ! It has thick， spotted petals that give off a rotten smell. The center is about the size of a household bucket.
After a rain， it may hold up to twelve pints of water!
After the rafflesia dies， it becomes a pool of thick liquid in which its seeds float. Elephants wandering through the forest step into the mushy pool， and the seeds glue themselves to their feet. As the animals stomp through the forest， their sticky feet pick up twigs and leaves. The elephants try to rid themselves of the sticky mess， in the same way people try to get bubble gum off their shoes. The elephants rub their feet against the roots of the vine. In no time， seeds left on the vine grow into more monstrous flowers !
Elephants help to________. 查看材料
A.provide food for the giant flower
B.water the rafflesia with their trunks
C.carry rafflesia seeds from one place to another
D.stomp out the awful smelling petals
