【单选题】
Teachers or Students The speaker, a teacher from a community college, addressed a sympathetic audience: Heads nodded in agreement when he said, 'High school English teachers are not doing their jobs.' He described the inadequacies of his students, all high school graduates who can use language only at a Grade 9 level. I was unable to determine from his answers to my questions how this Grade 9 level had been established. My topic is not standards nor its decline(降低). What the speaker was really saying is that he is no longer young; he has been teaching for sixteen years, and is able to think and speak like a mature adult. My point is that the frequent complaint of one generation about the one immediately following it is inevitable. It is also human nature to look for the reasons for our dissatisfaction. Before English became a school subject in the late nineteenth century, it was difficult to find the target of the blame for language deficiencies(缺陷). But since then, English teachers have been under constant attack. The complainers think they have hit upon an original ideA.As their own command of the language improves, they notice that young people do not have this same ability. Unaware that their own ability has developed through the years, they assume the new generation of young people must be hopeless in this respect. To the eyes and ears of sensitive adults the language of the young always seems inadequate. Since this concern about the decline and fall of the English language is not perceived as a generational phenomenon but rather as something new and peculiar to today's young people, it naturally follows that today's English teachers cannot be doing their jobs. Otherwise, young people would not commit offenses against the language. 第 36 题 The speaker the author mentioned in the passage believed that______ A.the language of the younger generation is usually inferior to that of the older generation
B.
the students had a poor command of English because they didn't work hard enough
C.
he was an excellent language teacher because he had been teaching English for sixteen years
D.
English teachers should be held responsible for the students' poor command of English

C.
低渗的相对渗透率曲线,束缚水饱和度高
D.
高渗的相对渗透率曲线,两相共渗区的范围小

三荷包回到衙内,他哥见了他,问起“那事怎么样了”。三荷包道:“不要说起,这事闹坏了!大哥,你另外委别人罢,这件事看上去不会成功。”
B.
笔者听说过挂羊头卖狗肉,如今鼠肉冒充羊肉却是实实在在,堂而皇之被端上了餐桌。笔者想问,这么多的伪劣羊肉甚至可能是“毒羊肉”都销售到了哪里?我们的监管部门又干嘛了?
C.
一名小学生每天摄入的肉食总量,不应当超过1个小鸡腿或2个鸡翅;小学生每日至少应睡10个小时,初中生9小时,高中生8小时。(北京市卫生局《北京市中小学生健康指引》)
D.
北京人艺最近推出四个轮换剧目:《天下第一楼》、《小井胡同》、《上帝的宠儿》和《洋麻将》,这些剧目都是经过观众检验的,确实是优秀剧目。
【单选题】心交感神经兴奋引起的心脏活动,下述哪项不正确
A.
心率加快
B.
心肌收缩力增强
C.
房室传导速度减慢
D.
动脉血压升高
E.
心输出量增多
F.
:C
G.
:心交感神经兴奋时,对心脏的主要作用是兴奋效应。主要表现为心率增快,房室传导加速,心肌收缩力增强,心输出量增多,血压升高。
【单选题】下列说法正确的是( )。
A.
取向力仅存在于极性分子之间
B.
凡是含氢的化合物其分子间必有氢键
C.
酸性由强到弱的顺序为:H2SO4>HClO4>H2SO3
D.
HCl分子溶于水生成H+和Cl-,所以HCl为离子晶体
【单选题】下列关于相对渗透率的说法中错误的是( )。
A.
无论润湿相还是非润湿相,随着本身饱和度增加,相对渗透率增加
B.
在亲水岩石中,水相分布在小孔隙及角隅,这对油的渗透率影响很小亲油岩石在同样的饱和度下,水分布在孔道中间,这严重影响着油相的流动
C.
虽取不同的渗透率为基数计算的相对渗透率不同,但对相对渗透率曲线没有影响
D.
对于多相渗流,油相渗透率或水相渗透率的高低与岩石孔隙结构、岩石润湿性、油水的粘度、油中的表面活性物质、油水饱和顺序、温度、驱动因素等有关
【单选题】下列物质中,酸性最强的是( )。
A.
取向力仅存在于极性分子之间
B.
凡分子中含有H原子的物质一定有氢键
C.
非极性分子中的化学键总是非极性键
D.
色散力仅存在于非极性分子
【单选题】下列关于岩石渗透率的说法错误的是()。
A.
绝对渗透率反映的是岩石本身的孔隙结构所决定的渗透能力,与流体性质无关
B.
有效渗透率是指当有两种以上的流体存在于岩石中,对其中一种流体测得的渗透率
C.
相对渗透率是指有效渗透率和绝对渗透率的比
D.
多种流体同时通过岩石时,各单相有效渗透率总是大于绝对渗透率
【单选题】下列关于岩石渗透率的说法中错误的是()。
A.
多相流体共存和流动时,岩石对某一相流体的通过能力大小,称为该相流体的相渗透率或有效渗透率,有效渗透率不仅与岩石本身的性质有关,还与各相流体的饱和度有关
B.
绝对渗透率是岩心中100%被一种流体所饱和时测定的渗透率,它只是岩石本身的一种属性,不随通过其中的流体的性质而变化
C.
同一岩石的有效渗透率之和等于该岩石的绝对渗透率
D.
相对渗透率是多相流体共存时,每一相流体的有效渗透率与一个基准渗透率的比值,实际是将有效渗透率无因次化
