                                                                                              哦,中学时代
       ①人近中年,常常ào_______悔青少年时由于贪玩或不明事理,làn________用了许多珍贵的时光。想想我的中学时代,我可算是个名副其实的“玩将”呢!下棋、画画、打球、说相声、钓鱼、掏鸟窝等等,玩的花样可多哩!
       ②我还喜欢文学。我那时记忆力极好,虽不能“过目成诵”,但一首诗念两遍就能吭吭巴巴背下来。也许如此,就不肯一字一句细嚼慢咽,所记住的诗歌常常不准确。我还写诗,自己插图,这种事有时上课时做。一心不以二用,便听不进老师在讲台上说些什么了。
       ③我的语文老师姓刘,他的古文底子颇好,要求学生分外严格,而严格的老师往往都是不留情面的。他那双富有捕捉力的目光,能发觉任何一个学生不守纪律的行动。瞧!这一次他发现我了。不等我解释就没收了我的诗集。晚间他把我叫过去,将诗集往桌上一拍,并不指责我上课写诗,而是说:“你自己看看里边有多少错?这都是不该错的地方,上课时我全都讲过了!”他的神色十分严厉,好像很生气。我不敢再说什么,拿了诗集走去。后来,我带着那本诗集,也就是那些对文学浓浓的兴趣和经不住推敲的知识离开学校,走进社会。
       ④社会给了我更多的知识。但我时时觉得,我离不开,甚至必须经常使用青少年时学到的知识,由此而感到那知识贫薄、残缺、有限。有时,在严厉的编jí_____挑出的许许多多错别字、病句或误用的标点符号时,只好窘笑。一次,我写了篇文章,引了一首古诗,我自以为记性颇好,没有核对原诗,结果收到一封读者客气而又认真的来信,指出错处。我知道,不是自己的记性差了,而是当初记得不认真。这时我就生出一种ào______悔的心情,恨不得重新回到中学时代,回到不留情面的刘老师身边,在那时光充yù_____,头脑敏捷的年岁里,纠正记忆中所有的错误,填满知识的空白处。把那些
由于贪玩而荒废掉的时光,都变成学习和刻苦努力的时光。哦,中学时代,多好的时代!
       ⑤当然,这是一种梦想。谁也不能回到过去。只有抓住自己的今天,自己的现在,才是最现实的。而且我还深深地认识到,青年时以为自己光阴无限,很少有时间的紧迫感。如果你正当年少,趁着时光正在煌煌而亲热地围绕着你,你就要牢牢抓住它。那么,你就有可能把这时光变成希望的一切,你如果这样做了,你长大不仅会做出一番成就,而且会成为一个真正懂得生命价值的人!                 (作者:冯骥才)

阅读下面短文, 从各题所给的A,B,C,D四个选项中选出最佳选项。

    One day, a teacher entered the classroom and told the students they would have a surprise test. After hearing that, all students were seated excitedly and waited for the test to begin soon. Then, the teacher gave the test papers to all students. However, the students were confused(困惑的)to see that there were no questions but just a black dot(点)in the center of the page. The teacher noticed the students' facial expressions and told them, "I want you to write about what you see there."

    The students were still confused but got started with the test. At the end of the class, the teacher took all the answer sheets and started reading each answer in front of all students. All of them described about the black dot and tried to explain its position. After the teacher finished reading, the whole class was silent.

    Then, the teacher began to explain. "Don't worry. I am not going to give you grades for this, but I just want you to think about something. Here everyone focused(聚焦)on the black dot and wrote about it, but no one wrote about the white paper, the same is with our lives. The white paper represents(象征)our whole life and the black spot represents problems in our life."

    Our life is a gift given to us by God, with love and care, and we always have reasons to celebrate-our friends around us , the job that provides us with livelihood , the miracles(奇迹)we see every day. Still we just focus on day to day problems like health issues, lack of money, problems in relationships and so on, but we never see that these problems are very small, compared to everything we have in our lives. So we should try to be happy and live life positively.
