成年人学英文的第一课和第二课刊出后，有数位读者写E-mail给我。有一位说道：「一篇文章的每一个单字都查到解释了，但整篇文章就是看不懂，怎麼办？」另一位说：「我的文法很差，没办法写完整的英文句子，要如何补救？」当发音和字汇都掌握住学习要领之后，剩下的就是「读」和「写」了，这才符合学习英文的正确步骤：听→说→读→写。台湾传统的学习方式由「写」开始，再「读」，然后才「说」，最后再去补救「听」力，可以说是背道而行，难怪效果不彰。那麼学习「读」的要诀是什麼呢？当然最重要的是能够了解整个句子的涵义。记得初中的时候背了很多文法规则，考试的分数虽然很高，但是对「读」的能力没有帮助。连那个时候流行的「英语九百句型」，也从来没有耐心读完过。然而我们今天能够看懂中文的文章，难道是因为我们熟悉中文的文法吗？答案是否定的。同样地，一个美国人虽然能阅读报纸，但是要求他做「英文文法分析」，他可能也会傻眼。英文的句子其实不需要去靠文法书中的规则去了解，文法书只应当作参考书，在有疑惑的时候才去查阅。平常应养成「约定成俗」的习惯，就是看别人怎麼用，然后「依样画葫芦」，日积月累，文法规则就化为无形了。因此，要训练「读」的技巧，不应该是靠文法规则，而是要多读。但是在读之前，要具备「了解句子」的基本能力，这就是我们的第三课─了解英文句子的要诀。了解英文句子的关键，在於先抓住「主词」和「动词」。看到一句很长的英文句子，不要害怕：先找主词，再找动词。动词如果是「及物动词」，再去找「受词」。主词、动词、受词之外，剩下的通通当做修饰语，有的修饰主词，有的修饰动词，有的修饰受词，有的修饰全句；任何两个完整的句子都可以用连接词连接起来。以上简单几句话，就是了解英文句子的基本观念。了解英文句子的第二步是熟悉英语的五种基本句型，其中前两种与不及物动词有关，后三种与及物动词有关。以下的句子中，用大括号表示{主词}或{受词}，中括号表示，剩下的部份都是修饰语。第一种与不及物动词有关的基本句型叫做「简单不及物句型」（Intransitive Verb，简称I），请背住以下五个句子

It is presented that indirect assimilation experiment of CMW data from TCFM method improves effectively not only on vertical velocity field but for precipitation.4 Based on theory analysis, E-Ir relationship is brought forward with two electrification mechanisms. One is inductive mechanism, i.e., cloud particles collide with precipitation particles then flick away, the other is noninductive mechanism because of different temperature, i.e., bigger supercooled cloud particles collide and freeze with hail particles combined with ice scraps. By means of CINRAD and FY2C data assimilation, precipitation intensity Ir can be obtained, then electric field intensity E, discharge time and locations can be achieved with supposed threshold 300KV/m. Though it can not distinguish between IC (Intra-Cloud) lightning and CG (Cloud-to-Ground) lightning, results are still comparable to LLS observations.5 Example analysis shows that the relationship between precipitation data from AMS and CG data from LLS is not very clear.

同化实验对于台风眼区的螺旋形雨带贡献显著，说明TCFM云导风资料同化实验不仅有效调整了模式的垂直速度场，还对降水模拟有了明显改善。4通过理论分析，利用云粒子与极化降水粒子碰撞并弹离的感应起电机制和较大过冷云滴与雹粒碰冻并产生冰屑的温差起电机制下得到的E-Ir，由雷达、卫星遥感资料直接和间接同化模拟得到Ir，来反推E，了解雷暴云中闪电强度的平面分布，设置放电阈值为300KV/m，推算出放电的位置和首次发生闪电的时间。

在基态，这种体系具有良好的热稳定性，而在激发态时能发生离子对内光诱导电子转移反应，导致其发生漂白和碘鎓盐的分解反应，产生具有引发作用的自由基。

The collisional orogenesis between north and south China blocks and intra-continental deformation finally led to the formation of the multiple Dabie-Tanlu-Sulu orogen.

华北与扬子地块碰撞造山作用与陆内变形最终造就了大别—郯庐—苏鲁复合造山带。

Applying whitening process and Gram-Schimdt orthogonalization and orthogonal subspace projection, an optimal transformation matrix is designed to minimize the ratio of intra-class distance to inter-class distance while imposing the constraint that different class centers after transformation are along specifically directions that are orthogonal each other.

以线性变换后样本的类内距离与类间距离之比最小作为准则函数，同时加上约束条件使变换后的样本中心沿着特定的正交方向，通过白化变换、Gram-Schimdt正交化和正交子空间投影求解约束准则函数得到最优变换矩阵。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
