12岁女孩独自生活的23个日夜


“空荡的房间里,住着一个上小学的小女孩。她的外婆已经病逝,妈妈染上非典,爸爸在医院隔离,女孩在自己的家里隔离。每天晚上,她家的灯光一直亮着。只要灯亮着,小女孩就还安全。这灯光,是生命之光……”
北京走学的校园网上,曾经有过这样一封帖子,引起很多网民的关注。为这个小女孩祝福的帖子连续数天登上排行榜前十名。
这个小女孩就是北大附小六年级学生麻文天,一个瘦小但坚强乐观的女孩子。几天前,她患非典的妈妈——北京大学经济学院教师李玫终于出院了,爸爸解除隔离回到家,天天也结束了隔离的日子,一家人终于团聚了。
当被问到是否害怕时,天天的回答显得挺坚强:“我不害怕,但有一点寂寞。”4月9日,天天的妈妈被确诊为非典患者,住进医院,爸爸也隔离在另一家医院。往日充盈着欢声笑语的家里顿时一片沉寂,12岁的天天开始了独立生活。
独立生活的第一天是在孤独中度过的。天天从没离开过父母这么长时间,她遇到的最大困难就是寂寞。她趴在家里的窗台上,望着外面的风景,一趴就是一两个小时。楼下有小朋友在踢毽子、跳绳,天天真想跑下楼去。可是,自已还在隔离期,可能带有传染病毒,不能出门,她收住了脚步。在离开父母的这些日子里,天天没有走出过家门一次。她每天起床后先看书,然后认认真真写作业。天天隔三四天才能和父母通一次话,后来通话的次数更少了。天天妈妈后来透露,她非常想打电话,但又不忍给天天打电话。有几次都拿起了话筒,甚至拔了几个号码,又把话筒放下了。她一脱离危险期,就立即给天天打电话,妈妈听到天天哭了,这是妈妈20多天来第一次听到孩子的哭声……
天天得到了不少人的关心。邻居给她送来自己家做的饭菜,总是那么准时,那么可口。学校开辟了网上“真情互动”版块。她每天都能接到来自父母的同事、北大爱心社、老师、同学、亲属的安慰和鼓励。天天非常感激这些帮助过她的人,她说他们是她“很铁的同盟军”。
“我非常感谢我的孩子。在这段时间里,我的很多亲友曾经惶惶不可终日,但是我的孩子却一直镇定地安慰我,独自生活了23天。”妈妈的话里充满了疼爱和自豪。

如果你是麻文天的同学,当她结束隔离回到学校的时候,你会对她说些什么呢请在下面的横线上写几句你最想说的话。

A  rainfores(雨林)is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in(吸收) heat from the sun and adjust (调节)the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters(灾害) all over the world.

In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit(受益).

There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run (长远看)it actually reduces the world’ s wood supply.

Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in (在于)the world’s shrinking rainforests.

小题1:..Rainforests can help to adjust the climate because they________.

A.reflect(反射) more heat into the atmosphere

B.bring about high rainfall throughout the world

C.rarely cause the temperature to drop lower than 16℃

D.reduce the effect of heat from the sun on the earth小题2:..What does the word “this” underlined in the third paragraph refer to?

A.We will lose much more than we can gain.

B.Humans have begun destroying rainforests.

C.People have a strong desire for resources.

D.Much carbon dioxide comes from burning rainforests.小题3:.What might be the best title for the text?

A.How to Save Rainforests

B.How to Protect Nature

C.Rainforests and the Environment

D.Rainforests and Medical Development
