　　刘姥姥只听见咯当咯当的响声，大有似乎打箩柜筛面的一般，不免东瞧西望的。忽见堂屋中柱子上挂着一个匣子，底下又坠着秤砣般一物，却不住的乱幌。刘姥姥心中想着：“这是什么爱物儿？有甚用呢？”正呆时，只听得“当”的一声，又若金钟铜磬一般，不防倒唬的一展眼。接着又是一连八九下。方欲问时，只见小丫头子们齐乱跑，说：“奶奶下来了。”说着，都迎出去了。刘姥姥屏声侧耳默候。忽见周瑞家的笑嘻嘻走过来，招手儿叫他。

　　只见那凤姐儿家常带着秋板貂鼠昭君套，围着攒珠勒子，穿着桃红撒花袄，石青刻丝灰鼠披风，大红洋绉银鼠皮裙，粉光脂艳，端端正正坐在那里，手内拿看小铜火箸儿拨手炉内的灰。平儿站在炕沿边，捧着小小的一个填漆茶盘，盘内一个小盖钟。凤姐也不接茶，也不抬头，只管拨手炉内的灰，慢慢的问道：“怎么还不请进来？”一面说，一面抬身要茶时，只见周瑞家的已带了两个人在地下站着呢。这才忙欲起身、犹未起身时，满面春风的问好，又嗔着周瑞家的怎么不早说。刘姥姥在地下已是拜了数拜，问姑奶奶安。凤姐忙说：“周姐姐，快搀起来，别拜罢，请坐。我年轻，不大认得，可也不知是什么辈数，不敢称呼。”周瑞家的忙回道：“这就是我才回的那姥姥了。”凤姐点头。刘姥姥已在炕沿上坐了。板儿便　躲在背后，百般的哄他出来作揖，他死也不肯。

　　这里凤姐叫人抓些果子与板儿吃，刚问些闲话时，周瑞家的向凤姐回话道：“太太说了，今日不得闲，二奶奶陪着便是一样。多谢费心想着。白来逛逛呢便罢，若有甚说的，只管告诉二奶奶，都是一样。”刘姥姥道：“也没甚说的，不过是来瞧瞧姑太太，姑奶奶，也是亲戚们的情分。”周瑞家的道：“没甚说的便罢，若有话，只管回二奶奶，是和太太一样的。”一面说，一面递眼色与刘姥姥。刘姥姥会意，未语先飞红脸，欲待不说，今日又所为何来？只得忍耻说道：“论理今儿初次见姑奶奶，却不该说，只是大远的奔了你老这里来，也少不的说了……今日我带了你侄儿来，也不为别的，只因他老子娘在家里，连吃的都没有。如今天又冷了，越想没个派头儿，只得带了你侄儿奔了你老来。”说着又推板儿道：“你那爹在家怎么教你来？打发咱们作煞事来？只顾吃果子咧。”凤姐早已明白了，听他不会说话，因笑止道：“不必说了，我知道了。”忙命快传饭来。一时周瑞家的传了一桌客饭来……

　　刘姥姥吃毕了饭，拉了板儿过来，舔舌咂嘴的道谢。凤姐笑道：“且请坐下，听我告诉你老人家。方才的意思，我已知道了。若论亲戚之间，原该不等上门来就该有照应才是。但如今家内杂事太烦，太太渐上了年纪，一时想不到也是有的。况是我近来接着管些事，都不知道这些亲戚们。二则外头看着虽是烈烈轰轰的，殊不知大有大的艰难去处，说与人也未必信罢。今儿你既老远的来了，又是头一次见我张口，怎好叫你空回去呢。可巧昨儿太太给我的丫头们做衣裳的二十两银子，我还没动呢，你若不嫌少，就暂且先拿了去罢。”那刘姥姥先听见告艰难，只当是没有，心里便突突的，后来听见给他二十两，喜的又浑身发痒起来，说道：“嗳，我也是知道艰难的。但俗语说的‘瘦死的骆驼比马大’，凭他怎样，你老拔根寒毛比我们的腰还粗呢！”周瑞家的见他说的粗鄙，只管使眼色止他。凤姐看见，笑而不睬，只命平儿把昨儿那包银子拿来，再拿一吊钱来，都送到刘姥姥的跟前。凤姐乃道：“这是二十两银子，暂且给这孩子做件冬衣罢。若不拿着，就真是怪我了。这钱雇车坐罢。……刘姥姥只管千恩万谢的，拿了银子钱，随了周瑞家的来至外面，仍从后门去了。

（选自《红楼梦》第六回 有删节）

（1 ）下列对小说有关内容的分析和概括，最恰当的两项是（     ）

A．刘姥姥通过周瑞家的进了贾府，在等待凤姐的时候，只见小丫头子们齐乱跑，说“奶奶下来了”。这一描写体现了凤姐在贾家的地位、权势和威严。

B．周瑞家的传达王夫人的意思，要刘姥姥“若有甚说的，只管告诉二奶奶”，并再次暗示和催促她，但刘姥姥却迟疑再三，言非所想，这是她的谨慎性格所致。

C．刘姥姥家因为生活困窘、衣食不济，前去贾府寻求经济帮助，作者设置刘姥姥这个角色进贾府，形象地说明了“上山擒虎易，开口求人难”的道理。

D．作者安排刘姥姥进贾府，就是以一个外人的眼光来描写贾家的奢华，自鸣钟，凤姐珠光宝气的打扮，传来的一桌子饭，都写出了荣府的豪富奢华。

E．刘姥姥说到为难之处，推出板儿说话，作者刻意安排这个角色使他成为行乞的幌子，缓解了刘姥姥的窘态，让人不觉得她的话语那么突兀。

     Even plants can run a fever, especially when they're under attack by insects or disease. But unlike

human, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago, adopting the infrared(红外线)scanning technology developed for military purposes and other satellites, physicist

Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are

under stress. The goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest problems.

     Even better, Paley's Remote Scanning Services Company could detect crop problems before they

became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured

the heat emitted by crops. The data were transformed into a colourcoded map showing where plants were running "fevers". Farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise

would.

     The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted

the new technology and longterm backers were hard to find. But with the renewed concern about

pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation.

Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of

agricultural land in the United States, " says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.
