阅读下面的短文,完成文后题目。
父 亲
①父亲是三天前的一个下午到家的,当时无人在家,他搁下背篼蹲在门口抽叶子烟。楼上的张婆以为是盲流呵斥他走开。我向父亲求证此事时,他像犯了错的孩子,局促地搓着双手,目光游移,嗫嚅着说:“下次,我一定会穿周正一点。”
②家里不宽敞,我们把父亲和儿子安排在一间屋里。父亲进屋不久,我就听见巴掌落在脸上的“啪”声,开门一看,见儿子正大吵大嗣:“你脏,你脏,不准你亲我,滚出去。”我对儿子动了武,妻子对我怒目而视。父亲垂着手,呆呆地站在一旁。这一夜很晚还听见父亲辗转反侧的声音。
③次日早晨,妻用不友好的腔调对父亲交代:“茶几上有好烟,有烟缸,别抽叶子烟,别乱抖烟灰。别动音响,别动气灶,别动冰箱,别动电视……”父亲谦恭地说:“叫我动,我也动不来的。”中午我俩回来,看见满地的水,父亲正蹲在地上,拿着帕子,手忙脚乱地擦地板。妻子一甩手进了卧室,“砰”地一下关了门。父亲便立即又像做错了事一般,不知所措起来。
④下午下了一场小雨,下班回来不见父亲。父亲回来时,湿漉漉的头发搭在皱纹堆砌的额头,松树皮一样的手提着一个塑料袋。他鞋也没有脱就进了屋,妻子“哼”了一声,又进了卧室。
⑤父亲说:“我去买东西了,不会买,也不知你们缺啥,就琢磨着买了这些。”
⑥父亲说:“蜂蜜治胃病,你记着,一早一晚都要喝一勺。她是用脑的人,核桃粉补脑,孙儿胃口不好,就给他买了健脾糕,吃了开胃。”
⑦父亲最后从贴身衣兜里拿出一个塑料袋,说:“这5000块钱是我卖鸡卖猪攒的,都攒3年了。我用处不大,你拖家带口的用得着,拿着。明天我就回去了,你有空就回来,看看你妈的坟,你爷的坟。没空回来,爸也不怪你,你们忙,单位纪律严呢!”说完父亲笑了一笑,摸出叶子烟,正要点,可能想起了妻的交代,又揣了回去。
⑧父亲执意要走。怎么留也不行,我决定叫辆出租车送他回去。
⑨一生都没坐过小车的父亲不知怎么打开门,他的手在门头东摸西摸,一脸尴尬。我上前一步,弯下腰来,打开车门,侍候父亲坐进车,再为他关上车门。父亲伸出头来,一脸的幸福,他说:“儿啊,爸算是村里最有福气的人了。”说完,抬手抹着眼圈,憨憨地笑着看我,我霎时百感交集。
⑩活在世上,活在城里,活在官场,我在许多人面前弯过腰,为许多人开过车门,但从没有为父亲弯腰开过车门。父亲是农民,我是干部,父亲是庄稼人,我是城里人,父亲这辈子已无法超越我们的高度,但我们有今天全仰仗父亲的奠基。父亲为我们弯了一辈子腰,吃了一辈子苦,操了一辈子心,人到老年依然念念不忑为子孙分担忧愁。但我们呢?给了他那么多不敬,仅仅为他开一次车门,就叫他心满意足,泪流满面。那一弯腰,对父亲来说,是一种孝道和良知。对我来说,是向他及天下所有像他一样的父亲的乞谅和深情致敬!

    The science fiction type of entertainment is considered by mot to be fathered by Jules Verne (A Journey to the Center of the Earth and Twenty Thousand Leagues Under the Sea) and H. G. Wells (The Time Machine and The War of the Worlds). Sei-Fi, as it is commonly shortened, is a fictional story in which science and technology have a significant influence on the characters and plot. Many such works are guesswork about what the future holds and how scientific findings and technological advances will shape humankind.

    Writing in the late 1800s, Jules Verne was remarkably successful in his 10 guesses about future technologies of air conditioning, automobiles, the Internet, television, and underwater, air, and space travel. Unbelievably, of all places from which to choose, Jules Verne guessed Tampa, Florida, USA as the launching site of the first project to the Moon, which was only 200 kilometers away from the actual 1969 location at Cape Canaveral, Florida.

    One of the best-known science fiction books is Nineteen Eighty-Four by George Orwell. Published in 1949, it was not meant as a prediction, but as a warning: Orwell was describing what he saw as the outcome of the ideas, trends, and emerging technologies of his time. Many invented terms from this novel have become common in everyday use, such as “big brother” and “doublethink”. Even the author's name has been made into an adjective—Orwellian—and has become a warning descriptor for situations where privacy is lost and the individual has no power and is completely controlled by the government. Nineteen Eighty-Four was translated into sixty-five languages within five years of its publication, setting a record that still stands.

    What helps bring science fiction into being is usually a new discovery or innovation. The author creates an analysis of the potential influence and consequences and then wraps it in a pleasant story. For example, the beginning of space exploration was followed a few years later by the Star Trek television program and movie series. The science fiction author's self-determined role is search the world of future possibilities upon the road which we are traveling.
