有一火电厂,在2003年1月1日通过建设项目环境影响报告书审批并建成投产,根据《火电厂大气污染物排放标准》(GB 13223—2003)中污染物排放控制要求的规定,该火电厂大气污染物排放执行第( )时段排放控制要求。

A.1

B.2

C.3

D.4

答案

参考答案:B

解析: 《火电厂大气污染物排放标准》(GB 13223—2003)中规定,污染物排放控制要求,划分如下时段的。 本标准分三个时段,对不同时期的火电厂建设项目分别规定了排放控制要求如下。 1996年12月31日前建成投产或通过建设项目环境影响报告书审批的新建、扩建、改建火电厂建设项目,执行第1时段排放控制要求。 1997年1月1日起至本标准实施前通过建设项目环境影响报告书审批的新建、扩建、改建火电厂建设项目,执行第1时段排放控制要求。 自2004年1月1日起,通过建设项目环境影响报告书审批的新建、扩建、改建火电厂建设项目(含在第2时段中通过环境影响报告书审批的新建、扩建、改建火电厂建设项目,自批准之日起满5年,在本标准实施前尚未开工建设的火电厂建设项目),执行第3时段排放控制要求。

单项选择题

A conventional teacher’s licensee usually requires a university degree in education plus an unpaid term of practice teaching. This has never made much sense. It excludes bright students who take degrees in other subjects, and might teach those subjects; it is costly and time-consuming for career-switchers, who must wait a year or more before they can enter a classroom; it is so rigid that private-school teachers or university professors with years of experience have to jump through hoops before they can start teaching in a state school. And there is virtually no evidence that it creates better teachers. For all that, it is ply backed by schools of education, which have a monopoly of teacher-training, and by teachers’ unions, whose members make more money when it is artificially hard for others to get into the profession.

Now, some 45 states and the Districts of Columbia offer an "alternative route" to a teacher’s licensee, up from only a handful in the 1980s. Alternative certification (AC) generally allows individuals with a university degree to begin teaching immediately after passing an entrance examination. These recruits, watched over by a mentor teach the subject they studied at university, and take education courses at a sponsoring university while drawing their salaries.

The traditional sort of American teacher is likely to be young, white and female. Alternative certification attracts more men and more non-whites. In Texas, for instance, roughly 90% of public-school teachers are white, but 40% of those who have joined through alternative certification are non-whites. The AC route also draws teachers willing to go where they are most needed. A survey of Troops to Teachers, a program that turns exsoldiers into public-school teachers (" Proud to serve again"), found that 39% of those taking part are willing to teach in inner-city schools, and 68% in rural areas.

Are they good teachers Officialdom is reluctant to release the details which might answer that question for certain. But anecdotal evidence suggests they do well. In New Jersey, which has been running this sort of program since 1984, rich districts, which can afford to be choosy, consistently hire more AC teachers than poor districts do. In Houston, Texas, where the Teach of America program (TFA) puts recent university graduates into poor communities as teachers, the most effective teachers are generally the TFA ones. " School principals are our biggest fans," Wendy Kopp, TFA’s president, says proudly.

So why not scrap the cumbersome teacher-licensing laws Frederick Hess, a professor at the University of Virginia, has written a paper for the Progressive Policy Institute arguing that teacher-licensing ought to be stripped to the bare essentials. Prospective teachers should be required only to hold a college degree, pass a test of essential skills, and be checked to make sure they do not have a criminal background. Other training is important, argues Mr. Hess, but the market, not state legislators, should decide what that training looks like. This notion of "competitive certification" has drawn favorable attention from the Bush administration.

Which of the following is true of alternative certification (AC)()

A. Many states have offered it since the 1980s

B. Schools of education and teachers’ unions opposed it

C. AC offers a flexible training program for new teachers

D. New recruits will require a university degree in education
