While the decline over the past de
6、cade is steep for teen readers, some data in the report shows that reading remains a big part of many childrens lives, and indicates how parents might help encourage more reading. According to the reports key findings, the proportion(比例) who say they hardly ever read for fun has gone from 8 percent
7、of 13-year-olds and 9 percent of 17-year-olds in 1984 to 22 percent and27 percent respectively today. The report data shows that pleasure reading levels for younger children, ages 28,remain largely the same. But the amount of time spent in reading each session has declined, from closer to an hour or
8、 more to closer to a half hour per session. When it comes to technology and reading, the report does little to counsel(建议)parents looking for data about the effect of e-readers and tablets on reading. It does point out that many parents still limit electronic reading, mainly due to concerns about in
9、creased screen time. The most hopeful data shared in the report shows clear evidence of parents serving as examples and important guides for their kids when it comes to reading. Data shows that kids and teens who do read frequently, compared to infrequent readers, have more books in the home, more b
10、ooks purchased for them, parents who read more often, and parents who set aside time for them to read. As the end of school approaches, and school vacation reading lists loom(逼近)ahead, parents might take this chance to step in and make their own summer reading list and plan a family trip to the libr
11、ary or bookstore.1.What is the Common Sense Media report probably about?A.Childrens reading habits.B.Quality of childrens books.C.Childrens after-class activities.D.Parent-child relationships.2.Where can you find the data that best supports children are reading a lot less for fun?A.In paragraph 2.B.
12、In paragraph 3.C.In paragraph 4.D.In paragraph 5.3.Why do many parents limit electronic reading?A.E-books are of poor quality.B.It could be a waste of time.C.It may harm childrens health.D.E-readers are expensive.4.How should parents encourage their children to read more?A.Act as role models for the
13、m.B.Ask then to write book reports.C.Set up reading groups for them.D.Talk with their reading class teachers.3、 Studies show farmland in Africa is often lacking in important nutrients. But researchers say a combination of farming methods may help. Researchers wonder how to increase production withou
14、t necessarily clearing more land to grow additional crops. American researchers say that can happen with greater use of an agricultural system called perennation. It mixes food crops with trees and perennial plants those that return year after year. Soil scientist John Reganold says, One of the majo
15、r problems is that the soils are fairly poor in most of the regions. So how do you grow food on poor soils? There have to be food production systems that can build the soil and improve the field. ” Mr. Reganold says poor soils may have resulted from years of weathering that washed away many nutrient
16、s. He says some farmers may have done more harm than good. “They have been actually using farming practices where theyre not putting in organic matter. Theyre not putting in fertilizers. They cant afford those things. And it just runs the soil down. So theyre worsening the situation. The scientist s
17、ays the word perennation defines three systems that are already used in Africa. The oldest of the threeis called evergreen agriculture.Thisiswherefarmers plant trees with theircrops. Farmers in Africa havebeen doing this for sixty years,butitseemstobe growing in popularity. The method is gaining wid
18、espread use in countries such as Niger, Burkina Faso, Malawi and Zambia. The trees are planted among maize(玉米), millet or sorghum crops. They not only add nitrogen to the soil through their roots, but also through their leaves when they fall off and break down. At other times of the year, the trees
19、can protect plants from strong sunlight.John Reganold says he knows of one woman who has had great success with perennation. “Shes a grandmother in her fifties. Her name is Rhoda Mang yana and she started using this system about twenty years ago. And her yields initially were about a ton of maize. N
20、ow with a good year she gets four tons per hectare,four times what she was getting.1.The purpose of the passage is to_.A.tell people how to increase productionB.introduce an agricultural system in AfricaC.introduce the oldest farming method in AfricaD.tell us how to prevent soils from being poor2.Wh
21、at does the underlined word “weathering” in Paragraph 4 most probably mean?A.Being exposed to wind and rain.B.Growing different crops.C.Being polluted severely.D.Being ploughed improperly.3.According to the passage, which of the following statements is WRONG?A.Perennation mixes food crops with trees
22、 and perennial plants.B.Poor soil is the main problem in increasing food production.C.Farmers may be more to blame for the present situation.D.American researchers first invented perennation.4.Why does John Reganold mention Rhoda Mangyana?A.To show the method is very popular in Africa.B.Because she
23、is an expert at farming production.C.To prove the farming method is effective.D.Because she produced more grains than anyone else in the country.4、 The Nazca Lines are a series of large ancient geoglyphs (地画) in the Nazca Desert, in southern Peru. It is ranging from geometric patterns to drawings of
24、 different animals and stylized human-like forms. The ancient lines can only be truly taken in from high in the air, leaving generations puzzled as to how these precise works could have been completed long before the documented invention of human flight. The Lines were first spotted when commercial
25、airlines began flying across the Peruvian desert in the 1920s. Who built them and what was their purpose? Are they roads, star pointers,maybe even a gigantic map? If the people who lived here 2,000 years ago had only a simple technology, how did they manage to construct such precise figures? Did the
26、y have a plan? These markings are like a vast puzzle. The Nazca Lines are the most outstanding group of geoglyphs in the world. There are also huge geoglyphs in Egypt, Malta, United States (Mississippi and California), Chile, Holivia and in other countries. But the Nazca geoglyphs, because of their
27、numbers, characteristics, dimensions and cultural continuity as they were made and remade throughout a certain history period, form the most impressive archeological (考古学的) group. The Nazca plain is unique for its ability to preserve the markings upon it, due to the combination of the climate (one o
28、f the driest on Earth, with only twenty minutes of rainfall per year) and the flat, stony ground which minimizes the effect of the wind at ground level. With no dust or sand to cover the plain and little rain or wind to erode (腐蚀) it, lines drawn here tend to stay drawn. These factors, combined with
29、 the existence of lighter-colored subsoil beneath the desert surface, provide a vast writing pad that is suited to the artist who wants to leave his mark eternal.1.What can we know about the Nazca Lines from the first two paragraphs?A.They were built as a big map.B.They were formed by nature.C.They are ancient lines in caves.D.They are huge markings in a desert.2.How many factors make the Nazca Lines the most impressive?A.Two.B.One.C.Four.D.Three.3.Why are the Nazca Lines well preserved?A.Because of the wind at ground level.B.Because of the existence of so
