让儿子独立一回
  儿子真是争气,以全县高考总分第三名的好成绩被上埴某著名大学录取。
  史工程师比当年自己考取大学还要高兴得多,满脸的阳光,满脸的春色。
  望子成龙,是中国人的传统。这些年来,儿子他妈真是费尽了心血。儿子读一年级,她也读一年级,年年这样陪着读陪着复习。
  如今儿子是如愿以偿考取了大学,他妈却病倒了。
  病床上的她念念不忘的是儿子开学在即,自己将不能亲自送儿子去大学,这叫她如何放心得下?她坚持叫丈夫无论如何要把儿子送到大学,安顿好了再回来。
  史工程师更放心不下妻子,与妻子商量说:“让儿子独立一回吧?”
  “不行” 没娶媳妇总是孩子。哪能让儿子一个人去大学。再说这孩子你也知道,他能行吗?”
  妻子的担心不是没有一点道理的。儿子长这么大了,没买过一回菜,没烧过一顿饭,没洗过一件衣,没拖过一次地,就连床也都是他妈铺的。自小到现在,从未单独出过一回门,就像鸡雏似的从未离开过母鸡翅膀的保护。而现在,猛一下就叫儿子一个人去经风雨见世面,她一百个放心不下。
  史工程师开导妻说:儿子是去上海读大学,又不是去非洲探险去神农架考察野人,不会有什么事的。想当年,我十七八岁时不去大串联吗,家里谁跟我去了?你在儿子年纪时,不是报名去了黄海边的建设兵团,你爹妈送你到了海边?没有吧。常言道,到啥山,砍啥柴。让儿子独立一回有好处……
  几乎是磨破了嘴皮子,好说歹说,妻才十分勉强十分不愿意地不再持反对意见,但她拖了一句:“就是我同意,儿子也不会同意的,人家父母都送,他父母不送,多没面子……” 
        简直是出乎意外,儿子很平静地说:“早该让我独立了。”  
  儿子去大学前一天,史工程师关照了又关照,诸如碰到意外情况立即找警察,安顿好后,先打电话回来,再写封详细的信……
  儿子去了三天,没有电话,儿子去了七天,依然没有音信。史工程师夫妇急了。妻子要史工程师无论如何亲自去一趟学校。
  正当史工程师准备去上海时,儿子的信来了。夫妇迫不及待地打开。不料随信纸带出的是查发票,共有:
  娄城至上海大巴车票一张     上海出租车票一张
  大三元酒家餐费发票一-张
  新华书店购书发票一张
  另附纸一份,上注明:
  付搬运费、服务费若干
  付冷饮费若干
  ……
  乖乖,不连学杂费,光这些额外开支,就两千多。
  看了儿子信才知道。儿子这次过了回独立瘾。他去上海时,不坐公共汽车乘豪华大巴;到了上海后,打的去学校;到了学校后,花钱请人搬行李,乃至挂蚊帐铺床他都未自己动手。为了搞好关系,他买了一箱冰淇淋,凡那天在他宿舍的,不管是同学教师,还是他们的父母、朋友,一概由他请了;第三天,他又请同宿舍的到大三元酒家聚了聚……
  史工程师看了信和发票,不知说什么才好。他妻子看了,一颗七上八下的心总算放了下来。她很欣慰地说:“我这儿子,是做大事的料!”
  史工程师没有接嘴,他大概正在为如何为儿子回信而伤脑筋呢。
1. 请以史工程师的口吻概述这篇微型小说的故事情节。(不超过80 字)

2. 结合小说对“妻子”言行的描写,具体分析“妻子”这个人物形象。

D
Seeing a volcano erupt (喷发) is a wonderful experience, and you can really feel the beat by climbing to the summit(山顶) of Pacaya for a close-up view. There are guided tours every day up this highly active volcano from Antigua. Giving travelers a chance to see Mother Nature at her most powerful.
Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won’t miss the Pacaya-tour companies.
But climbing Pacaya is no easy job: it is 2560 metres high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb, you hear the dull sounds of eruptions high above. Steaming. Hot remains from recent eruptions begin to line the path as you near the active summit; the McKenney Cone(火山锥). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the relative safety of the old, inactive summit.
Many tours are timed so that you arrive at the cone of the volcano is plenty of time for sunset and the full contrast between the erupting red lava(熔岩) and the darkening sky. On a good day the view from the summit is extremely exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot streams up to 100 metres into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night. the burning lava quietly falls down tae side of the volcano. For you, too, it is time to get down .
