Ⅲ.阅读理解
阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
A
There are lots of insects that farmers hate. But there also are some they like. They protect crops against damage from other insects. A good example is the lady beetle, which is also known as the ladybug(瓢虫)．
Lady beetle are a natural control for aphids(蚜虫). Lady beetles are red, orange or black. They often have black spots, though some have light colored spots. Different kinds of lady beetles have different numbers of spots. There are lady beetles with four, five, seven and fourteen spots.
Many of the well­known kinds of lady beetles come from Asia or Europe. They now are common throughout the United States.
American scientists imported one kind of lady beetle, the multicolored Asian lady beetle, as early as 1916. They released them as an attempt to control some kinds of insects. Over the years, the beetle has become established, possibly helped by some that arrived with imported plants on ships.
Experts say over 450 kinds of lady beetles are found in North America. Some are native to the area. Others have been brought from other places. Almost all are helpful to farmers.
The Asian lady beetles now in the United States probably came from Japan. The Asian lady beetle eats aphids that damage crops like soybeans, fruits and berries.
In the southern United States, Asian lady beetles have reduced the need for farmers to use pest­killing poisons on pecan trees. This popular tree nut suffers from aphids and other pests that the lady beetles eat.
But some people say the Asian lady beetle has itself become a pest. They worry that the lady beetles may eat their late­autumn fruit crops.
Experts say Asian lady beetles may appear in large numbers in some years. But they say the insects are too helpful to be considered as pests.
1．What do ladybugs look like?
A．All kinds of ladybugs are of the same color.
B．Most of them are red, orange or black.
C．They each have the same number of spots on them.
D．Most of them have fourteen spots.
答案：B　由第二段第二句可知B项正确，同时排除A项；由第二段第四句可知C项错误；D项文中没有提及。
2．Asian ladybugs have been in the United States for______.
A．nine decades
B．hundreds of years
C．half a century
D．a century
答案：A　由第四段第一句可知自1916年至今应为90多年，但离一个世纪还有好几年，所以A项为最佳选项。
3．According to the passage the following statements are supported EXCEPT________.
A．there are more than 450 kinds of ladybugs in North America, including native ones
B．only some imported ladybugs are helpful to the local plants
C．soybeans, fruits and berries are favorites of aphids.
D．pecan trees are common in the south of America
答案：B　由第五段最后一句可知B项与文章内容相悖。其余选项所述内容都与文章内容相符。
4．According to the experts, ladybugs are________.
A．more helpful than considered as pets
B．more pests than helpful insects
C．helpful as well as destructive
D．are more destructive than helpful
答案：A　根据末段最后一句可知，专家的观点是瓢虫益大于弊，不应被视为害虫。
B
If you want your land to keep fertile, you must try to stop soil from being carried away by water or winds. When soil is taken away by flowing water or blowing winds, we call it soil erosion. Ways have been found to stop soil erosion, and this is known as soil conservation. One way of stopping soil erosion is to grow small plants such as grasses. These plants are referred to as cover crops, whose roots hold the soil tightly together. The rain water cannot wash away the soil. When trees and tall bushes are planted at the edges of an open field, soil erosion by strong winds cannot take place. The trees and bushes, which act as a very big and firm wall, protect the open land from the winds. The way to stop soil erosion on slopes is to build terraces on the slope of hillside and mountainside. When the slope of a hillside is cut into“steps”， water carrying soil cannot run straight down the terraces, which are used to slow down the speed of the flowing water containing much soil in it. In this way most of the soil in the water is left behind on the terraces. Much soil in it is kept.
5．What take place in soil erosion?
A．Flood happens to the fertile land.
B．A large quantity of the earth wears away gradually.
C．Terraces are built on the slope of hillside or mountainside.
D．Plants are grown to protect the open land.
答案：B　由文章首句可知由于土壤风化，土壤中的大量有机物流失。
6．Besides afforestation, another method to fight against soil erosion is to________.
A．build terraces
B．build walls
C．plant trees
D．plant flowers
答案：A　由文中“The way to stop soil erosion on slopes is to build terraces”可知修建梯田是防止土壤风化的又一举措。
7．Trees and tall bushes are planted around an open field________.
A．because their roots hold soil tightly
B．to stop soil from being blown away by winds
C．because soil erosion causes terrible damage to crops
D．to keep the ecological balance
答案：B　由文中第七句可知，把树木和高灌木丛种植在空地上可以有效防止土壤风化的发生。
8．Which of the following is the best title of the passage?
A．What Causes Soil Erosion
B．The Importance of Afforestation
C．Rain Erosion and Wind Erosion
D．Erosion and the Ways to Fight Against Erosions
答案：D　文章主要讲述了土壤风化以及预防的措施，故D项概括较为全面。

沁园春·雪 <毛泽东>
北国风光，千里冰封，万里雪飘。
望长城内外，惟余莽莽；
大河上下，顿失滔滔。
山舞银蛇，原驰蜡象，
欲与天公试比高。
须晴日，看红装素裹，分外妖娆。
江山如此多娇，引无数英雄竞折腰。
惜秦皇汉武，略输文采；
唐宗宋祖，稍逊风骚。
一代天骄，成吉思汗，
只识弯弓射大雕。
俱往矣，数风流人物，还看今朝。
