起重机的常见事故有：（）、其他伤害。

[问答题]The well-known phrase “honoring the teacher and respecting his teaching” has long been a part of Chinese tradition and culture. According to recent Global Teacher Status Index, teachers have the highest social status in China across the world. The following is a new report on people’s view on teaching profession. Read it carefully and write your response in about 300 words, in which you should:　　1. summarize briefly the public’s view on teaching profession nowadays;　　2. give your comment.　　Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks.　　As Teacher’s Day is approaching, the China Youth Daily received 1,089 reader responses from a nationwide survey. Results indicated that the teaching profession is still a respectable occupation; 91.6 percent voted that they wanted the most outstanding people to be teachers.　　“The profession of teacher should be the most respectable occupation in our society. The group should consist of the most outstanding people, or our nation’s development will be affected,” a respondent stated in the poll.　　Asked about which kind of teachers are the most outstanding ones, some readers answered: “Not all talented teachers are outstanding in their fields. An excellent teacher ought to be first of all a person of high morals, since teachers educate young people.”　　Even more interesting, 76.3 percent of the respondents said that a teacher is someone who influenced them most. But people’s views toward what kind of teachers are good teachers have changed. Another survey this June showed that 31.6 percent of the people admired knowledgeable teachers, 67.6 percent liked teachers who made their classes easy and interesting, and 51.9 percent preferred teachers with a good sense of humor. In short, being knowledgeable is the first and most important aspect of being a teacher, and on this basis, students clearly prefer lively and witty teachers.　　The bad news: recent years have seen the rapid reduction of normal universities and colleges. Many have been upgraded to comprehensive universities by name changes and mergers. Education experts worry that this kind of development will harm teacher training because these courses were conducted in those types of universities or colleges.　　The good news: the latest government work report states that the country would provide free education for students attending teacher training universities. The policy has become a reality as a total of 11,000 students enrolled in six teacher-training universities bare now begun enjoying free education as of last week. These students began registration respectively at the six universities based in Beijing, Shanghai, Changchun, Wuhan, Xi’an and Chongqing on September 4th.　　73 percent of the readers who responded to the survey believed that the free education policy signals that the country is paying greater attention to education and teachers. 60.1 percent of the respondents said that the policy should be popularized and extended to more normal universities and colleges.　　Of those polled, the majority (55.6 percent) said that they wanted to be university or college teachers, because of the “high salary and low pressure, good working environment and non-fixed office hours.” “Some teachers even have their own research program.” 29.5 percent wanted to be middle school teachers, 13.4 percent wanted to be kindergarten teachers, and 8.2 percent say they didn’t want to teach at all.　　Some respondents said that the salary of rural teachers in central and western areas should be increased. If not, even those students who enjoy free education in normal universities and love the teaching jobs will still face the ultimate question: choose their dream job or find something better to make ends meet?
