It 作形式主语与ｉt引导强调句得比较 It 作形式主语代替主语从句,主要就是为了平衡句子结构,主语从句得连接词没有变化、而i ｔ引导得强调句则就是对句子某一部分进行强调,无论强调得就是什么成分,都可用连词that。被强调部分指人时也可用who/ｗｈｏｍ、例如: ａ) It isａpitｙｔhaｔyoｕｄidn’t go ｔo seｅｔhｅｆilm.您不去瞧那场电影真可惜。 b) It doeｓn’tｉntereｓt me whethｅrｙou sｕｃceed or not、我对您成功与否不感兴趣、 c) Ｉｔisｉn thｅｍoｒnｉng thaｔｔｈe ｍurder took place. 谋杀案就是在早上发生得、(强调句型) d) Ｉt is Joｈn tｈat broke ｔｈeｗｉｎdow。就是Joｈn打碎得窗户。(强调句型) 2、用ｉt 作形式主语得结构 (1)It is + 名词＋从句 It is ａfaｃt tｈat…事实就是… Ｉt ｉs an honor ｔhat …非常荣幸 It ｉｓｃommon knowlｅdge ｔhat …就是常识 (2)Ｉt is + 形容词+从句 It is naturａl thａt…很自然… It ｉｓstrａｎｇe that…奇怪得就是…(3) It ｉｓ＋不及物动词+ 从句 Ｉｔｓｅems thａｔ…似乎… Ｉt ｈappeneｄthat…碰巧… Iｔappeaｒs that…似乎…

混凝土工程练习题复习课程

一判断题 （一）混凝土工程 A.钢筋工程 1.施工现场钢筋代换时，相同级别的钢筋只要代换后截面积不减少就可以满足要求。 2．钢筋冷拉后表面不应发生裂纹或局部颈缩现象，且拉伸和冷弯试验应符合规定的要求。 3．交叉钢筋网片利用点焊以代替人工绑扎是生产机械化和提高工效的有效措施。 4．钢筋和预埋件电弧焊部位外观不得有裂纹、咬边、凹陷、焊瘤、夹渣和气孔等缺陷。 5．钢筋骨架应满足设计要求的型号、直径、根数和间距正确，且钢筋的力学性能合格就达到验收合格的要求。 B.模板工程 1．拆模程序一般应是先支先拆，后支后拆，非承重先拆，承重的后拆。 2．重大结构的模板系统可以不需设计，请有经验的工人安装就可以满足强度、刚度和稳定性要求。3．承重模板只要不会损坏混凝土表面即可拆除。 4．承重模板必须待混凝土达到规定强度才可拆除。 C.混凝土工程 1.混凝土能凝结硬化获得强度是由于水泥水化反应的结果，适宜的用水量和浇水养护保持湿度是保证混凝土硬化的唯一条件。 2．混凝土结构施工缝是指先浇筑的混凝土和后浇筑的混凝土结合面，而不是指一道缝。 3．混凝土施工缝是指先浇筑的混凝土和后浇筑的混凝土在结合处的一道缝。 4．现浇混凝土框架结构若采用柱梁板同时浇注工艺时，必须在柱浇注后1～1.5h,才可浇注上面的梁板结构。 5．混凝土施工缝宜留在结构受拉力较小且便于施工的部位。 6．对混凝土拌和物运输的基本要求是混凝土不离析、保证规定的坍落度、在混凝土初凝前有充分时间进行浇注施工。 7．使用外加剂的普遍性已使它成为混凝土的第五种材料。 8. 大体积混凝土结构整体性要求较高,一般分层浇筑。 9. 钢筋混凝土框架结构整体性要求较高,一般不允许留施工缝。 （二）预应力工程 1．预应力混凝土先张法施工一般适合生产中小型预制构件。 2．预应力混凝土后张法施工，孔道灌浆是为了增加预应力钢筋与混凝土的粘结力。 3．预应力混凝土后张法施工，混凝土是通过预应力钢筋与混凝土的粘结力获得预应力。 4．预应力混凝土与普通混凝土相比可有效的利用高强钢筋，提高混凝土的抗裂性、刚度，减小构件截面尺寸等优点。 5．钢绞线强度高、柔性好、没有接头，故广泛使用于预应力混凝土结构。 二选择题 （二）混凝土工程 A.钢筋工程

1.高中英语语法通霸句子结构成分分析主语谓语宾语定语状语补语

高中英语语法通霸1. 句子结构成分分析主语谓语宾语定语状语补语定语

英语的句子成分主要有六种：即主语、谓语、宾语、定语、状语和补语。（可以熟记为：主谓宾，定状补）除了这六种主要成分之外，还有“表语”和“同位语”的说法。但表语和系动词一起作谓语，因此划分成分时，划分在谓语上。同位语分为主语同位语和宾语同位语，属于主语或宾语的一部分。 考点1.划分句子成分时的常用符号 英语中划分句子成分的符号 主语在下面画直线 谓语在下面画曲线 宾语在下面画双横线 定语在下面画虚线（一行点使我们想到一排钉子，“钉”谐音为“定语”的“定”） 状语下面为短横线（短横线使我们想到短木桩，木桩撞（状）钟） 补语上一短横，下一短横（下一短横好像是为了弥补上面短横间的空隙） 同位语上下双曲线（都有曲折，上下位置基本相同） 考点1.主语 主语是一个句子所叙述的主体，一般位于句首，通常由名词性的词来充当。 可以作主语的词性或语法结构： 1. 名词 2. 代词 3. 数词 4. 不定式 5. 动名词 6. 主语从句等表示。 7. 名词化的形容词（如the rich） 在英语中，形容词、副词和介词短语是不能作主语的。如果它们在句首时，句子可能是倒装句，真正的主语在后面。 On the desk are some books. (主语是books，所以用are) Down jumps the boy. (主语是the boy，所以用jumps ) Gone are the days. (主语是the days，所以用are) 练习1.在下面句子的主语下面画横线，并说出由什么充当。 1.During the 1990s, American country music has become more and more popular. 2.We often speak English in class. 3.One-third of the students in this class are girls. 4.To swim in the river is a great pleasure. 5.Smoking does harm to the health.

（2）as与which的区别 a、位置不同 as可放在主句后，主句前或主句中间；which只能放在主句后。 b、as起连接作用，表达说话人的观点、看法，并指出主句内容的根据或出处，意为“正如，正像”。 Which相当于并列句，可以用and this来代替，意为“这一点，这件事’”。 注意：as常用于下列结构：as we know/ as is known to all, as we all can see, as has been said before/above, as might be excepted, as is often the case, 一般不能用which代替as。 c、在从句中作主语时，which既可作系动词be的主语也可作实义动词的主语，而as只可作系动词be的主语。 二、只用that不用which的情况 1、.先行词为all , much, everything, nothing , something ,anything, nothing, none, the one等不定代词时 2、先行词被only, any, few, little, no , all, just , very ,right等修饰时. 3、当先行词是最高级或被形容词最高级修饰时。

高中英语必备语法(精华版)

高中英语语法 第一章名词性从句 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。名词性从句的功能相当于名词词组, 它在复合句中能担任主语 .宾语 .表语 .同位语 .介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句 .宾语从句 .表语从句和同位语从句。一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it 代替，而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 b) It doesn’t interest me whether you succeed or not. 我对你成功与否不感兴趣。 c) It is in the morning that the murder took place. 谋杀案是在早上发生的。（强调句型） d) It is John that broke the window. 是John打碎的窗户。（强调句型） 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that …事实是…

It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) It is ＋形容词＋从句 It is natural that…很自然… It is strange that…奇怪的是… (3) It is ＋不及物动词＋从句 It seems that…似乎… It happened that…碰巧… It appears that…似乎… (4) It ＋过去分词＋从句 It is reported that…据报道… It has been proved that…已证实… It is said that…据说… 3. 主语从句不可位于句首的五种情况 （1）if 引导的主语从句不可居于复合句句首。 （2）It is said /reported…结构中的主语从句不可提前。例如： 正确表达：It is said that President Jiang will visit our school next week. 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如： 正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him. （4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如：
