诗歌鉴赏。阅读《浣溪沙》完成小题。(6分)

浣溪沙

苏轼

游蕲水清泉寺,寺临兰溪,溪水西流。

山下兰芽短浸溪, 松间沙路净无泥,萧萧暮雨子规啼。

谁道人生无再少? 门前流水尚能西!休将白发唱黄鸡。

小题1:.对这首词内容理解不当的一项是(    )(3分)

A.首句七字既点出了游清泉寺时的时令,也点明了兰溪之名的由来。

B.次句写漫步溪边,“松间沙路净无泥”化用了白居易的“沙路润无泥”。苏轼将“润”改为“净”,更加突出了兰溪的洁净和一尘不染。

C.“潇潇暮雨子规啼”点出了净无泥的原因,同时又烘托出自己贬官黄州期间的凄凉环境和沉郁、悲凉的羁旅之情。

D.尾句反用白居易《醉歌》“黄鸡催晓丑时鸣”“镜里朱颜看已失”的诗意,认为即使到了暮年,也不应有那种“黄鸡催晓”、朱颜已失的衰颓心态,体现了作者在贬谪期间旷达振作的精神状态。小题2:.对这首词赏析不当的一项是(    )(3分)

A.上片只是写实景,其内心所唤起的应是对大自然的喜爱及对人生的回味,这就引出了下片的对人生的哲思。

B.江水的东流不返,正如人的青春年华只有一次一样,都是不可抗拒的自然规律,曾使古今无数人为之悲叹。而作者此际面对着眼前西流的兰溪水,却产生奇妙的遐想:既然溪水可以西流,人为什么不可以重新拥有青春年华呢?作者说的人生之“再少”,就是道教徒所企求的“返老还童”。

C.全诗用浅俗的语言,但“浅浅语亦觉不凡”,充分体现了作者善于驾驭语意,并使其蕴含韵味的能力,而句中折射的哲理、积极和高亢的情调,千百年来更是感动了无数的读者。

D.全词的特点是即景抒慨,写景纯用白描,细致淡雅;抒慨昂扬振拔,富有哲理。

阅读理解。

      If English means endless new words,difficult grammar and sometimes strange pronunciation,

you are wrong.Haven't you noticed that you have become smarter since you started to learn a

language?

     According to a new study by a British university,learning a second language can lead to an

increase in your brain power.Researchers found that learning other languages changes grey

matter.This is the area of the brain which processes information.It is similar to the way that

exercise builds muscles.

     The study also found the effect is greater the younger people learn a second language.A

team led by Dr Andrea Mechelli,from University College London,took a group of Britons

who only spoke English.They were compared with a group of "early bilinguals" who had learnt

a second language before the age of five,as well as a number of later learners.

      Scans showed that grey matter density(密度)in the brain was greater in bilinguals than in

people without a second language.But the longer a person waited before mastering a new

language,the smaller the difference.

     "Our findings suggest that the structure of the brain is changed by the experience of learning

a second language," said the scientists.It means that the change itself increases the ability to learn.

      Professor Dylan Vaughan Jones of the University of Wales has researched the link between

bilingualism and math skill."Having two languages gives you two windows on the world and makes

the brain more flexible," he said."You are actually going beyond language and have a better

understanding of different ideas."

     The findings were matched in a study of native Italian speakers who had learned English as a

second language between the ages of 2 and 34.Reading,writing,and comprehension were all tested.

The results showed that the younger they started to learn,the better."Studying a language means you

get an entrance to another world," explained the scientists.

B.there is no difference between a later second language learner and one who doesn't know a second

language
