For most people, it’s almost impossible to operate a computer without a mouse, let alone surf the Internet. A well-chosen mouse, which is really handy, flexible and convenient in controlling the screen, enables us to edit text, browse web page and download what we want ,with the functions of inserting, deleting, moving and copying. It can even bring us a flood of music, movies and PC games. However, relying too much on mouse clicking makes us lazier and less creative both mentally and physically. Too much ready information on our fingertips leaves little room for knowledge pursuing and too many ready answers make us less excited in finding truth. 查看更多

阅读下面的文字,完成下列各题。

高原,我的中国色

乔 良

东亚细亚的腹地,一派空旷辽远,触目惊心的苍黄。连那条从巴颜喀拉的山岩间夺路而来的大河,也暴烈地流泻着一川黏稠的黄色!这就是高原。黄土高原。

浑黄的天地间,走来一个黄皮肤的老者。看不清他的面孔,听不清他的声音,只有那被黄土染成褐色的长髯在被太阳喷成紫色的浮尘中飘拂……老者身后,逶迤着长长、长长一列只在身体的隐秘处裹着兽皮的男人和女人。

一棵巨大的柏树,便在这人群中生下根来。所有黄皮肤的男人女人和他们的后人,都把这巨树唤作轩辕柏。它的根须像无数手指抠进黄土,扎向地心,用力合抱住整个儿的高原。

始皇帝横扫六合的战车,汉高祖豪唱大风的猛士,倚在驼峰上西出阳关的商旅,打着呼哨、浑身酒气的成吉思汗的铁骑,和五午年的岁月一道,从这金子样的高原上骄傲地走过去,走过去,直到……

暮云垂落下来,低矮的天地尽头,走来一个小小的黑点。一个军人。

他站在一架冲沟纵横、褶皱斑驳的山梁上。残阳把他周身涂成一色金黄。他伸出手臂,出神地欣赏着自己的皮肤。金黄的晖光从手臂上滑落下去,掉在高原上。一样的颜色。他想,我的肤色和高原一样。

豪迈的西风从长空飒然而至。他的衣襟和裤角同时低唱起暗哑而粗犷的古歌。刹那间,他获得了人与天地自然,与遥远的初民时代那种无缝无隙的交合。是一种虚空又充实,疏朗又密集,渺小又雄大的感觉。

他不禁微微一笑。然而,只一笑,那难以言喻的快感消退了。渐渐塞满胸壑的,是无边的冷寞,莫名的苍凉。竟然没有一只飞鸟,竟然没有一丛绿草。只有我,他想。我和高原。于是他又想,这冷漠、这苍凉不仅仅属于我,还属于遗落在高原上的千年长史。

畏惧盗寇的商贾们抛离了驼队踩出的丝绸古道。面对异族的武夫们丢弃了千里烽燧和兵刃甲胃。一路凄惶,簇拥着玉辇华盖,偏安向丰盈又富庶的南方。那叫人柔肠寸断的杏花雨呵,竟把炎黄子民们孔武剽悍的魂魄和膂力一并溶化!而历史,却在某个迷茫的黄昏,被埋进深深的黄土。

他感到胸口有一团东西被揪得发疼。他想喊。他想站到最高的那架山梁上去,对着苍茫的穹窿嘶喊:难道华夏民族所有的武士,都走进了始皇陵兵马俑的行列?

没有风。没有声息。高原沉默着。

一块没有精壮和血性汉子的土地是悲哀的。

他想起了他那些戴着立体声耳机、抱着六弦琴横穿斑马线的兄弟们。他们全都身条瘦长,脸色煞白,像一根根垂在瓜架上的丝瓜。他们要去参加这一年中的第三百六十七次家庭舞会了吧?他们的迪斯科跳得真好。他们忧郁的歌声真动人。但,他们只从银幕上见过高原和黄土。他们不知道紫外线直射进皮肤和毛孔时的滋味,更不知道那黄土堆成的高原上埋着的古中国。

可那才是中国,那才叫中国。在病榻上呻吟了八百年,又被人凌辱了二百年的,不是真正的中国。真正的中国是闪着丝绸之光、敦煌之光、修筑起长城,开凿出运河,创造了道教,融合了佛教,同化了一支支异族入侵者的中国。

真正的中国是一条好汉。这裸着青筋、露着傲骨的高原也是一条好汉。

他想,我也该是这样的汉子。

他想,有了这样的男子汉,高原,这金子似的高原便不会死去。因为轩辕柏在这里扎着一根粗大的、深邃的根茎。

这个人,这个军人,就是我。

这篇散文中作者设置的“轩辕柏”有什么象征意义?请结合阅读材料简要分析。

                                                                               

“是一种虚实又充实,疏朗又密集,渺小又雄大的感觉。”作者将褒贬之词同时用来描写这种感觉,这是一种什么样的感觉?“他”为什么会产生这样的感觉?

                                                                                

文章结尾说:“这个人,这个军人,就是我。”一句中与上文哪一句照应?怎样理解其中的“我”?请你谈谈作者在文中如何渲染与张扬着自己的情绪?

                                                                                 

下列对文章的赏析,不正确的两项是       (    )

    A.“残阳把他周身涂成一色金黄”,他为自己有着与“金子样的高原”同样的颜色而自豪,就是他为做一个中国人而骄傲。

    B.“他”站在黄土高原上,看到“竟然没有一只飞鸟,竟然没有一丛绿草”,深感植被破坏严重,内心无比冷寞,苍凉。

    C.丰盈富庶的南方,柔肠寸断的杏花雨象征了温柔安逸、没有血性的土地,销磨了一代代中国人慷慨悲歌之气,积极进取之心。

    D.“他”想呼喊,仅仅因为现代人的苍白无知,压得他几乎喘不过气来。所以他的大声呐喊是希望唤回高原的血性来。

    E.全文语言铿锵有力,掷地有声,在凛然傲气中又渗透着无限的历史苍凉感,如同一幅黄昏时分的画卷,述说着遥远的历史又翘首期待着美好的明天。

Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates (碳水化合物)一all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a high一protein diet lost about 1.8 extra pounds, and more body fat, than those having a standard-protein diet.

Wycherley from the University of South" Australia in Adelaide, the lead author on the study says it’s possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans.

It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds——and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. “The studies are generally far too short to tell effect,” Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, “It makes no real difference which of the weight-loss ways one chooses.”

1.According to Wycherley’s analysis, dieters should take in more ______.

A. fat         B. carbohydrates       C. protein D. calories

2.What can we learn from the studies?

A. It bums more calories to deal with carbohydrates.

B. Protein helps keep muscle mass which bums calories.

C. Vegetables contain more protein than animals.

D. No more calories are burned while the body is resting.

3.What is Levine’s attitude towards the conclusion of the studies?

A. Doubtful. B. Supportive. C. Curious. D. Agreeable.
