乡间读书过个年

一近年关,苍茫的岁末时分总是格外地撩动着城里游子的心境。一时间周围总像有声音在急不可待地催促我踏上归家的行程,收拾好行李,常常丢三落四地忘却家人嘱咐携带的东西,却总忘不了整理好几册自己要读的书。说真的,再也没有比过年时到乡间,更能唤起我读中国古书的情怀了。

在祥和氤氲的冬日乡间,我有机会独自面对着收割后一派深沉平静的田野,感受着漂浮在乡间晨曦里那种白露未曦的独特气息。村舍间红色的桃符、响亮的鞭炮交织起洋洋的喜气,院落里农事已毕的乡亲们围炉沽酒,在微微醉意中品味着日常生活小满足中的大幸福。在乡间读书总是让人有着太多的感动与联想,乡土、家园、传统、朴素生命里的浮世悲欢,纯粹中国式的生活感受,都在这样一个极其中国化的时节中凸显出来,让你远离尘嚣,亲近风土,走选民间与历史的深处,刻骨铭心地触摸到在庄稼与方言间流淌的中国灵魂与东方血脉。

走进异地城里读书已经多年,读出那份困惑与浮躁却是始料未及的。今天读书人的心灵早已失却了往昔的宁静与纯粹。生活变得丰富多彩,但也喧闹不堪,一切让人目不暇接,但心灵似乎更加苍白贫血。物欲横行代替了文雅从容的涵咏,膨胀的功利之心侵吞了悠游的读书之乐在城市钢筋水泥丛林里的读书人忙碌于排行榜、传媒、畅销书和不着边际的研讨会,这种现代人的读书生活中可能什么都有,就是没有真正的读书。身在香港繁华之地的董桥先生刻闲章一枚说:"我是个村郎,只合守篷窗、茅屋、梅花帐。"

年头岁尾偶尔从生活的漩涡里平静下来,惊心岁月,又流年暗换,蓦然发觉生命里又有一些日子远去了。对一个读书人来说,过年时回乡间读书,在心灵宁静与平和的无穷感悟中,才能真的留住岁月,留住自我。

(1)结合材料,分析作者为什么说“再也没有比过年时到乡间,更能唤起我读中国古书的情怀了”。

Scientist Florence Wambugu works with farmers in Kenya, a country in East Africa. She helps them grow bigger and better crops. Wambugu is especially interested in finding simple ways to produce more food.

In the past ten years, Wambugu has spent much of her time studying sweet potatoes, which are an important food in her part of Kenya. A virus (病毒) kept attacking the plants. It stopped the sweet potatoes from growing well. Because of the virus, some farmers lost three quarters of their crops.

Wambugu went to war against the virus. Her research for a way to save the sweet potatoes led to a lab in St. Louis, Missouri.

The lab mainly works on genes (基因), the chemical “computer programs” found in the cells of living things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have found ways to move genes from one living thing to another. That process is called genetic engineering.

Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off the virus. Wambugu tested her research in Kenya, and her plants produced wonderful sweet potatoes.

That’s just the beginning, Wambugu believes. Genetically modified (转基因的) foods, she thinks, could help farmers in poor countries grow badly needed crops, thus, fewer people will go hungry.

小题1:The text is written mainly to _______.

A.tell us sweet potatoes are in danger of being attacked by a virus

B.introduce Wambugu’s contribution to genetic engineering

C.introduce a new way of killing plant viruses

D.tell how hard Wambugu worked in her lab for three years小题2:What caused Wambugu to set up a lab in St. Louis, Missouri?

A.Her wish to save sweet potatoes in Kenya.

B.Her great interest in genetic engineering.

C.Her love for sweet potatoes.

D.Her interest in plant life.小题3:The fourth paragraph mainly explains what ________ is.

A.a crop virus

B.chemical technology

C.a computer program

D.genetic engineering小题4: What is Wambugu’s attitude toward “genetic engineering”?

A.It will help more hungry people.

B.It should be carefully used.

C.It has more disadvantages than disadvantages.

D.It is a too expensive technology at present.
