阅读下面的文段,完成问题。

  【梅花酒】你道是咱不该,这招状供写的明白。本一点孝顺的心怀,倒做了惹祸的胚胎。我只道官吏每还覆勘,怎将咱屈斩首在长街!第一要素旗枪鲜血洒,第二要三尺雪将死尸埋,第三要三年旱示天灾,咱誓愿委实大。

  【收江南】呀,这的是衙门从古向南开,就中无个不冤哉!痛杀我娇姿弱体闭泉台,旱三年以外,则落的悠悠流恨似长淮。

  【鸳鸯煞尾】从今后把金牌势剑从头摆,将滥官污吏都杀坏,与天子分忧,万民除害……嘱咐你爹爹,收养我奶奶。可怜他无妇无儿,谁管顾年衰迈!再将那文卷舒开,(带云)爹爹,也把我窦娥名下,(唱)屈死的强伏罪名儿改。

  [注]这是《窦娥冤》第四折后部分,也就是全剧结尾部分。这是窦娥向其父窦天章——两淮提刑肃政廉访使诉说冤情后的三段唱词,它带有总结全剧、揭示主旨的意味。

1.【梅花酒】曲中“我只道官吏每还覆勘,怎将咱屈斩首在长街”这一句唱词比第三折中的“我怕连累婆婆,屈招了药死公公,今日赴法场典刑”这一句揭露得更深刻,试简析之。

2.【收江南】曲中“衙门从古向南开,就中无个不冤哉!”是将俗语“衙门从古向南开,有理无钱莫进来”改造而成的,前者比后者反映的当时现实更深刻,结合《窦娥冤》简析之。

3.你如何理解作者借窦娥之口为当时社会开出的药方——“从今后把金牌势剑从头摆,将滥官污吏都杀坏,与天子分忧,万民除害”?

4.把本折中的【梅花酒】【鸳鸯煞尾】的曲词同课本对照一下,窦娥的哪些品性没变?

阅读下面短文,回答文后的5个问题,并把答案写在答题卡指定区域内。

[1] If you read a newspaper or listen to a newscast(news report) recently, you may hear or read a strange word, “staycation.” Staycation is a new word the American press(newspapers, radio, and television) is using to describe a vacation very close to your own home, or simply staying at home during your vacation. It is a combination of the words “stay” and “vacation”.

[2] According to many news reports, these staycations are very popular among American families this year. Why? The high price of gasoline for cars and airplanes has made it very expensive for Americans to travel compared to past years. When you combine this with the weak American dollar, it all adds up to people deciding to stay close to home during their traditional summer vacations. Of course, some places are more interesting to “stay home at” than others. And if you live in a very small town, well, you may just want to skip your vacation and save your time up to next year!

[3] Everything is expensive nowadays, and let’s face it—a vacation just may not be in your plan this year. You don’t have to give up family fun just because you can’t              ; instead, follow my tips for an economical staycation filled with old favorites and new adventures!
