Cloze test.

     Lulu is a brave pet in our shelter. As you know, there are a lot of forest fires during the summer season.
Many forests are badly damaged by fire each year. Not far from our shelter, a forest caught fire during this
hot summer. We were in a heat wave which had been   1   for three days.
     Lulu rushed towards the forest where flames sent out a terrible   2 . I no longer had any hope that Lulu
would come back to the shelter. In fact, I was waiting for the firemen to announce his   3   in the forest,
when suddenly, a fireman burst into my shelter and   4   me that my dog Lulu had   5   to save four kittens
who were trapped by the flames. According to the fireman, Lulu seized the kittens, one by one moving them
to a safe place. I immediately accompanied the fireman to the forest to   6   the rescued kittens. When we
arrived at the   7   of the incident, we found Lulu was not there. Then we heard the   8   of a dog from the
forest barking furiously. I recognized it was my dog Lulu. The fireman followed the tracks of the dog until
we found him barking   9   by the side of an injured fireman who was lying on the ground and desperately
waiting for rescue. Thanks to Lulu, four kittens and a fireman were saved.
     That day, I was very proud of Lulu for his two heroic  10  towards the kittens and the fireman Lulu showed
much compassion (同情) for both animals like him and for a human being who was trying to  11  the fire with
his colleagues.
     This true story of genuine love and compassion shows us that pets are loving,  12  and considerate. We
should love and protect them. One day they could do us a good turn.

近年来，多媒体技术在课堂上得到了广泛运用，然而，前两天在某市一中这举行的教学公开课评比中，大量使用电脑多媒体等现代教学手段的教师反而没有获奖。理由是，电脑多媒体虽然先进，信息量大，能使课堂丰富多彩，但用多了并不是好事，有可能使学生思维退化，校长还举了个例子。他说：“语文课一个重要功能是培养学生的想象能力，有的老师为把讲的东西变成图像、声音，用多媒体展示，看似很热闹，但学生进行自主想象的机会被抹杀了。数学也是这样，有的时候，数学课上会出现一个情景，要想证明这个题目，得加一条辅助线，辅助线加在哪里，老师鼠标一点，啪出来了，但是这并不是学生认识的过程，而是强加给学生的，长期这样训练的结果是什么是学生对事物的探索能力降低了。”
