问题 单项选择题

随着三峡文物考古工作的不断深入,峡江地区文明起源、发展,史前文化的脉络已开始清晰地展现在世人面前.考古学家兴奋地发现,三峡考古实际上是在长江流域打开一部可与黄河流域相媲美的“中国二十四史”,从它们之间交相辉映、交流融合的一件件文化遗存中,中华文明的生命活力、包容百川的基因图谱清晰可辨. 1999年,重庆考古队在丰都高家镇、烟墩堡发现多处旧石器时代遗址,一下将三峡地区的旧石器文化向前推了5~10万年.从1994年的调查开始,库区共找到50多处旧石器遗存的地点,其中14处还保留着原生地层,在丰都高家镇还发现一处露天石器制作工场. 进入三峡地区的考古队还找到5 000多年前后的部落遗址80多处.令考古学家兴奋的是,在湖北、湖南广泛分布的大溪文化、屈家岭文化和石家河文化遗存也存在于忠县哨棚嘴文化遗址中.新的考古发现说明,先民在新石器时代甚至更早就已经在峡江地区打通了一条文化走廊,三峡库区正是中原文化与楚文化交融的一个重要通道.巴人是三峡库区的先民,大约存在于夏商至西周时期.三峡库区夏商至西周的考古发现大大改变了人们过去对这一段早期巴人文化知之甚少的状况,已经发现的巴人遗址和墓地已达百余处,使巴人文化从商周到战国形成一个不问断的完整序列.1996年以来,在巫山县紧邻大宁河东北侧发现的双堰塘遗址,忠县发现的中坝、哨棚嘴、瓦渣地等遗址群,云阳小江之侧的李家坝遗址和墓地,面积都达数万平方米,内涵丰富,是商至汉初时期巴人的中心活动地带.人们在这里发现了大量巴人的建筑、冶金、窑业遗址,可以说已经打开了深入研究巴人社会的神秘之门,巴人的历史面纱正在逐渐揭开. 走进库区一个个设施简陋的文物仓库,一件件青铜器、漆器、陶器令人眼花缭乱,不得不惊叹我们祖先高超的创造技艺.到目前为止,仅三峡重庆库区出土的珍贵文物就达上千件,出土一般文物上万件.三峡的文物古迹,上下数万年.这是在特殊的地理环境和自然风光中形成的一长串历史遗痕.深入研究它们,可以提高今后如何更好地建设三峡地区的认识;认真思考它们,可以增加对三峡历史的敬意.

以下对“三峡考古"的有关理解正确的一项是_____ .

A.峡江文明联系着中原文化与楚文化,专家估计其先民可能在旧石器时代就已经在此打通了一条文化走廊

B.1994年,考古队在三峡库区发现了50处以上的旧石器时代遗址,其中14处保留着原生地层

C.高家镇、烟墩堡发现的多处旧石器时代遗址,可以证明三峡地区在5~10万年前就出现了旧石器文化

D.有确凿的考古证据可以说明,新石器遗址哨棚嘴文化包含有大溪文化、屈家岭文化和石家河文化

答案

参考答案:A

解析:B项应为“从1994年开始”;C项后半句应为“将三峡地区的旧石器文化向前推了5~10万年”;D项四种文化之间是并列关系,非种属关系.

In a world as fast-changing and full of information as our own, all of us need to know how to learn well. Yet evidence suggests that most of us don’t use the learning techniques that science has proved the most effective.

The scientific literature evaluating these techniques goes back to decades and across thousands of articles. It’s far too extensive and complex for the average parent, teacher or employer to look through. Fortunately, a team of five leading psychologists have done the job for us.

Professor John Dunlosky and other psychologists closely examined 10 learning strategies and rated each from high to low utility(实用) on the basis of the evidence they’ve gathered. Here’s part of their conclusions:

In contrast to familiar practices, the effective learning strategies with the most evidence to support them aren’t well known outside the lab. Take distributed practice, for example. This strategy involves spreading out your study time, rather than engaging in one marathon. Cramming (死记硬背)information at the last minute may allow you to get through that test or meeting, but the material will quickly disappear from your memory. It’s much more effective to look through the material at intervals over time.

And the longer you want to remember the information, whether it’s two weeks or two years, the longer the intervals should be.

The second learning strategy that is highly recommended by Dunlosky is practice testing. Yes, more tests---but there not for a grade. Research shows that the mere act of calling information to mind strengthens that knowledge and aids in future retrieval (检索). While practice testing is not a common strategy---despite the strong evidence supporting it ---there is one familiar approach that captures its benefits: using flash cards. And now flash cards can be presented in digital form. Both distributed practice and practice testing were rated as having “high utility” by Dunlosky.

小题1:How did the psychologists study and rate the learning strategies?

A.By analyzing the materials gathered in the past years.

B.By asking some students questions about their study.

C.By doing some experiments on the objects in the lab.

D.By asking parents and teachers to look through the articles.小题2:The underlined word “extensive” in Para.2 means _____.

A.small in amount

B.easy or quick to do

C.more than is needed

D.dealing with a lot of information小题3:About distributed practice and practice testing, it’s true that _____.

A.many students have benefited a lot from them

B.they were first put forward by John Dunlosky

C.only a small number of experts know about them

D.psychologists are studying whether they are effective小题4:The strategy of distributed practice shows that ______.

A.we should not study for long hours every day

B.reviewing what we have studied is of little help

C.the shorter the interval is, the better we’ll study

D.doing repetition at intervals is the best way小题5:The evidence shows that the strategy of practice testing ______.

A.is a way to use flash cards to help study

B.is mainly used to help us remember well

C.helps know about students’ grades in time

D.is a way widely used to strengthen memory
