Thirty years ago, Lake Ponkapog in Hartwell, New Jersey, was full of life? Many birds and animals lived beside the water, which was full of fish. But the lake water is polluted now. It is in a color of dirty brown, and it is filled with strange plants.
How did this happen? First, we must think about how water gets into Lake Ponkapog. When
it rains, water comes into the lake from all around. In the past, there were forests all around Lake Ponkapog, so the rainwater was clean.
Now there are many homes around the lake. People often use chemicals in their gardens. They use other chemicals inside their houses for cleaning or killing insects. There arc also many businesses. Businesses use chemicals in their machines or shops. Other chemicals fall onto the ground from cars or trucks. When it rains, the rainwater picks up all the chemicals from homes
and businesses and then carries them into the lake. They pollute the water and kill the animals.
Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats. But
oil and gas from boats often get into the lake. So more bad chemicals go into the water this way.
People in Hartwell are worried. They love their lake and want to save it. Will it be possible?
A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at work. They must also be more careful about gas and oil and other chemicals on the ground. And they mustn't use motorboats any more
on the lake. All these may change people's lives. Only then can Lake Ponkapog be a beautiful, clean lake again.
49.Chemicals from homes and businesses__________________
A. are always clean
B. can help the animals
C. are good for the lake
D. get into the rainwater
50.Clean rainwater will mean _________________________________.
A. more boats on the lake
B. more dirty things in the lake

D. a dirtier lake
51.To save Lake Ponkapog, people need to ______________________.
A. be more careful about chemicals
B. use less water
C. grow fewer plants in the gardens
D. use more motorboats on the lake

西安工业大学 教学督导通报 2008年本字第6期总第154期2008年9月18日 2008年9月10日下午学校教学督导团举行了2008-2009学年的第一次督导团例会，会议由督导团团长史永高教授主持。副校长张君安、教务处副处长齐华及全体督导团成员参加了会议。会议主要总结了开学三周来的教学进展情况，审定了2008－2009学年度的课堂教学明星参选人的资格，制定了教学督导团本学期的工作计划。现主要内容通报如下： 一．教学情况 1. 课堂教学情况 1）个别教师上课不注意着装，身穿短裤、沙滩鞋，有的老师到上课时间还在接听手机，希望教师铭记教书育人的原则，为人师表，身教重于言教。 2）依然有部分教师多媒体课件制作水平低，有的多媒体PPT制作每屏大量文字表述，字多而小，色彩对比小，学生在座位上根本看不清楚。加上教师讲课翻屏又快，使得学生根本来不及理解和记笔记，造成课堂教学效果较差。 3）个别教师采用在课堂上播放电影的形式进行授课，形式多样可以肯定，但是不应整堂播放，教师应有讲解。建议院（系）组织教学研讨，对授课内容认真审查，切实保障每节课堂的教学效果，对属于学生课外补充内容，最好不要占
用课堂时间。 4）部分教师课堂组织意识不强，上课不注意维护纪律，不考勤、不对学生提出应有的纪律要求，造成课堂秩序较差，学生听课率低。 2. 教学设备维护情况 督导团专家听课中发现和教师反映教学设备问题，主要有： 1）金花校区教4-303教室的黑板磨损严重，不宜继续使用； 2）金花校区4F-J1的多媒体投影仪模糊，影响上课效果，建议更换； 3）未央校区教C104投影仪模糊，教C105投影仪损坏； 4）未央校区教B楼四层教室都是台式话筒，教师讲课不方便，建议更换。 5）未央校区多媒体教室的黑板前的灯能否单独设置开关，目前设置影响播放媒体的效果。 3. 学风情况 1）部分班级的学生到课率偏低，特别是毕业班到课率更低，有的不足三分之一； 2）学生拥有教材率低，有的教师定了教材而学生不买教材，或者各自去买旧教材，造成教材版本不一； 3）部分课程课堂秩序不好，学生听课率低。 二． 2008－2009学年度课堂教学明星候选人的确定 为促进课堂教学质量稳步提高，鼓励教师不断完善教学水平，学校定期进行课堂教学明星教师评选活动，每两个学年一个评选周期。明星教师候选人由院（系）培养并推荐、教师自荐和督导团推荐三者结合产生，并经督导团初步审核确定，本次候选人推选过程中，督导团在各院（系）推荐参选人名单基础上，根据平时所掌握的课堂教学情况，又推荐了4名教师，共确定课堂教学明星候选人45人（名单见附件）。
