题目内容
The flowers were so lovely that they ________ in no time.
- A.sold
- B.had been sold
- C.were sold

思路分析:由主句的时态可推断从句也该用一般过去时态,因为这两个动作几乎是同步进行的,并且flowers和sell之间为被动关系,故A项不对,选C项。
【点评】该题考查时态和语态,难度适中。时态和语态往往放在同一个句子中考查。考生在选择时必须兼顾,不能只考虑时态或只考虑语态。
It was starting to get dark and Bobby turned to walk home when suddenly his eyes caught the setting sun’s rays reflecting off something along the roadside. He reached down and discovered a shiny dime(一角钱). Never before has anyone felt so wealthy as Bobby felt at that moment.
As he held his new found treasure, a warmth spread throughout his entire body and he walked into the first store he saw.
His excitement quickly turned cold when the salesperson told him that he couldn’t buy anything with only a dime.
He saw a flower shop and went inside to wait in line. When the shop owner asked if he could help him, Bobby presented the dime and asked if he could buy one flower for his mother’s Christmas gift. The shop owner looked at Bobby and his ten cents offering. Then he said to him, “You just wait here and I’ll see what I can do for you.”
The sound of the door closed as the last customer left. All alone in the shop, Bobby began to feel cold and afraid. Suddenly the shop owner came out. There, before Bobby’s eyes, lay twelve long stem, red roses, with leaves of green and tiny white flowers all tied together with a big silver bow. Bobby’s heart sank as the owner picked them up and placed them gently into a long white box. “That will be ten cents, young man.” The shop owner said reaching out his hand for the dime.
Sensing the boy’s reluctance(勉强), the shop owner added, “I just happened to have some roses on sale for ten cents a dozen. Would you like them?”
When the man placed the long box into his hands, he knew it was true. Walking out of the door that the owner was holding, Bobby heard the shopkeeper say, “Merry Christmas, son.”

Color use in nature
Nature is very colorful, full of different hues(色调)that delight the eye. What makes these colors and why do they exist?
Causes of Colors in Nature
Colors in nature are formed in two ways. Pigments, like the melanin in skin and many animal furs, produce most blacks, browns, reds and yellows. Most plants are green due to chlorophyll(叶绿素). Other colors are caused by structure, like many greens, blues, and whites. Blue bird’s feathers actually contain black pigment, but their structure causes them to appear blue. The scattering of light by tiny dust particles in the air, viewed against the black background of space, makes the sky look blue too.
Color Use in Plants
Color has a great effect on the survival of plants and animals. Flowers have bright hues and patterns to attract insects. These insects move from one flower to another, making sure seeds are produced. Bees can see colors we cannot, i.e. ultraviolet, and follow these patterns of stripes or dots to the inside of the flower.
Not only flowers but also fruits use color for the good of the plant. An unripe fruit mixes in with the leaves, but ripe berries contrast, becoming more appealing to the creatures who eat them. Birds are especially drawn to red fruit, and in turn help the plant by broadcasting its seeds.
Camouflage(伪装)in Nature
Many colors and patterns camouflage animals who want to avoid enemies. Some animals have damaging shapes to break up their outline, so an enemy will not recognize them. The eye, a very recognizable animal characteristic, is often disguised by a black stripe or patch. Light color below makes up for the shadow on the underside of many fish, amphibians and mammals.
Some animals even change colors to better camouflage themselves, seasonally like the snowshoe hare.
Warning Coloration and Mimicry(动态伪装)
Warning colors make an animal more visible rather than hidden. These usually indicate a negative aspect of the animal, like the bad taste of a monarch butterfly, smelly smell or painful bite of a bee. Usually black and a contrasting color (white, yellow, orange or red) form a striking pattern in these creatures, and frighten their enemies away. Nature is tricky, though, and sometimes harmless creatures pretend the patterns of harmful ones to scare off animals living on meat too.
Social Coloration in Nature
Sometimes coloration is important socially. Male birds, typically more colorful, defend their territories and attract females. Eggs may use color and pattern to remain hidden. When they hatch, parents feed the nestlings when they see the bright pattern in their gaping mouths.
Taking a closer look at nature throws light on how color is used in marvelous ways!
