  (1)我们在田野散步:我,我的母亲,我的妻子和儿子。

  (2)母亲本不愿出来的。她老了,身体不好,走远一点就觉得很累。我说,正因为如此,才应该多走走,母亲信服地点点头,便去拿外套。她现在很听我的话,就像我小时候很听她的话一样。

  (3)天气很好。今年的春天来得太迟,太迟了,有一些老人挺不住。但是春天总算来了。我的母亲又熬过了一个严冬。   

  (4)A这南方初春的田野,大块小块的新绿随意地铺着,有的浓,有的淡;树上的嫩芽也密了;田里的冬水也咕咕地起着水泡。这一切都使人想着一样东西——生命。   

  (5)我和母亲走在前面,我的妻子和儿子走在后面。小家伙突然叫起来:“前面也是妈妈和儿子,后面也是妈妈和儿子。”我们都笑了。   

  (6)后来发生了分歧:母亲要走大路,大路平顺;我的儿子要走小路,小路有意思。不过,一切都取决于我。我的母亲老了,她早已习惯听从她强壮的儿子;我的儿子还小,他还习惯听从他高大的父亲;妻子呢,在外面,她总是听我的。一霎时,我感到了责任的重大。我想一个两全的办法,找不出;我想拆散一家人,分成两路,各得其所,终不愿意。我决定委屈儿子,因为我伴同他的时日还长。我说:“走大路。”   

  (7)但是母亲摸摸孙儿的小脑瓜,变了主意:“还是走小路吧。”B她的眼随小路望去:那里有金色的菜花,两行整齐的桑树,尽头一口水波粼粼的鱼塘。“我走不过去的地方,你就背着我。”母亲对我说。

  (8)这样,我们在阳光下,向着那菜花、桑树和鱼塘走去。到了一处,我蹲下来,背起了母亲,妻子也蹲下来,背起了儿子。我的母亲虽然高大,然而很瘦,自然不算重;儿子虽然很胖,毕竟幼小,自然也轻。但我和妻子都是慢慢地,稳稳地,走得很仔细,好像我背上的同她背上的加起来,就是整个世界

     It is natural that young people are often uncomfortable(不自在) when they are with their parents.

They say that their parents don't understand them. They often think that their parents are out of touch

with modern ways; that they are too serious and too strict with their children; and that they seldom

give their children a free hand.

     It is true that parents often find it difficult to win their children's trust and they tend to forget how

they themselves felt when young. For example, young people like to act on the spot without much

thinking. It is one of their ways to show that they have grown up and they can face any difficult

situation. Older people worry more easily. Most of them plan things ahead, at least in the back of

their minds, and do not like their plans to be upset by something unexpected.

     When you want your parents to let you do something, you will have better success if you ask

before you really start doing it.

     Young people often make their parents angry with their choices in clothes, in entertainment and

in music. But they do not mean to cause any trouble; it is just that they feel cut off from the older

people's world, into which they have not yet been accepted. That's why young people want to

make a new culture of their own. And if their parents do not like their music or entertainment or

clothes or their way of speech, this will make the young people extremely happy.

     Sometimes you are so proud of yourself that you do not want your parents to say "yes" to wha

t you do. All you want is to be left alone and do what you like. It is natural enough, after being a

child for so many years, when you were completely under your parents' control.

     If you plan to control your life, you'd better win your parents over and try to get them to

understand you. If your parents see that you have a high sense of responsibility, they will certainly

give you the right to do what you want to do.
