Passage 2
Questions 6 to 10 are based on the following passage:
When aluminum was first produced about a hundred and fifty years ago, it was so difficult to separate form the ores in which it was found that its price was higher than that of gold. The price remained high until a new process was discovered for refining the metal with the aid of electricity approximately three quarters of a century later. The new method was so much cheaper that aluminum because practical for many purposes, one of which was making pots and pans.
Aluminum is lightweight, rustproof and easily shaped into different forms. By mixing it with other metals, scientists have been able to produce a variety of alloys, some of which have the strength of steel but weigh only one third as much.
Today, the uses of aluminum are innumerable. Perhaps its most important use is in transportation. Aluminum is found in the engine of automobiles, in the hulls of boats. It is also used in many parts of airplanes. In fact, the huge “airbus” planes would probably never have been produced if aluminum did not exist. By making vehicles lighter in weight aluminum has greatly reduced the amount of fuel needed to move them, Aluminum is also being used extensively in the building industry in some countries.
Since aluminum is such a versatile (多用的) metal, it is fortunate that bauxite (铝土矿), which is one of its chief sources, is also one of the earth’s most plentiful substances. As the source of aluminum is almost inexhaustible, we can expect that more and more uses will be found for this versatile metal.

在全面实施素质教育的要求下,怎样评价学生的优、良、中、差呢?为此,我制定了这样的标准:一是在大纲规定的基础科60分以上,并能发现自己的特长且有所发展的,视为及格;二是基础科及格或良好,特长科明显超过同年级学生的,视为良好;三是基础科良好,特长科大大超过同年级学生或有所发明创造的,视为优秀;四是仅基础科及格或仅特长科有所发展的,均视为不及格;五是仅基础科良好,或特长科单方独进的,视为畸形发展,作降格评价。这一评价标准的实施,使绝大部分差生“都抬起头来走路”,找到了自己成才的优势与途径。也使文化课考试分数好的学生不再自我感觉良好,从而找到了良性互补、和谐发展的新路子。通过一个学期的实践,学生的学习积极性明显高涨,各科学习成绩有了大幅度的提高,各科总分由原来年级的倒数第二,上升到年级的第二名。
问题:请你针对案例中制定的评价标准,谈谈自己的看法。
与其他媒介新闻评论相比较,广播电视新闻评论的特点是什么,是如何体现出来的?
当今社会围观者对落水者冷漠,医生对患者冷漠,问该如何开展尊重生命的教育,应从哪几方面着手?

名字解释:二次设备。
如何正确认识“先富”与“共富”的关系?
假如领导派你和一个有矛盾的同志一起出差,你如何处理?在日常生活中,出现这样的事情你是如何处理的?试举例说明。
