四、总结（引深探究  15分钟）

一般现在时态的被动语态

如果想要表达“孩子们喜欢这些歌曲”、“简照看这只猫”，我们会说

Children love these songs. Jane looks after the cat. 如果想要说“这些歌曲

受到孩子们的喜爱”、“这只猫由简照看”，该 ：怎样用英语表达呢？

这两组句子表达的重点很不一样：第一组句子侧重“人”，即某人怎样；而

第二组句子侧重“事”，即某事如何。所以，第一组句子使用主动语态，而

第二组句子使用被动语态。被动语态的表达有固定的结构。我们先来对比

以下两组句子： 

Children            love        these songs.         主动语态

(动作执行者)      （动作）    （动作接受者）

These songs  are loved   by children           被动语态

(动作接受者）      （动作）     (动作执行者)

Jane     looks after      the cat.              主动语态

(动作执行者)      （动作）     （动作接受者）

The cat   is looked after   by Jane.     被动语态

（动作接受者）      （动作）        (动作执行者)

从以上对比我们可以看出被动语态的构成和用法。

1、精讲规则

（1）.被动语态的构成

被动语态中动作接受者作句子主语，动作执行者置于句末，用by连接

，有时可以省去不用。谓语动词由“be+动词的过去分词”构成，一般现在

时被动语态的结构为：

主语（动作接受者）+is/am/are + 动词的过去分词+（by+动作执行者）

被动语态的句型总结如下：

肯定句： 主语+be+过去分词+（by ~）

否定句：主语+be not+过去分词+（by ~）

一般疑问句： Be + 主语+ 过去分词+（by ~）?

特殊疑问句： 特殊疑问词+ be + 主语+ 过去分词+（by ~）?

下面我们来看一些具体例子 

----Is the boy called Jack? 这个男孩儿叫杰克吗？

---- Yes, he is. / No, he isn’t. 是的。/ 不是。

The baby is not looked after by his father . 这个小孩儿不由他父亲照顾。

----What languages are spoken in Canada? 加拿大说什么语言？

----French and English. 法语和英语。

（2）. 被动语态的用法

同学们会问，什么时候使用被动语态呢？一般说来，被动语态用于以下

几种情况：

1）要表达“被……”、“受……”、“遭……”、“让……”之类的语义。如：

教师很受尊敬。→ Teachers are well respected.

这孩子很招人喜爱。→ The child is well loved by people.

2) 强调动作接受者。 如：

他远近闻名。→ He is known far and wide.

3) 不知道或没有必要指出动作的执行者。如：

房子每天都有人打扫。→ The room is cleaned every day.

总的说来，判断该不该用被动语态主要是看主语是否为谓语动词的行为对象。

四、总结（引深探究  15分钟）

在进行英语写作时，要按照西方人的思维方式来布局谋篇。在语篇的开始方面，应该直截了当表达观点，态度明确。在语篇的发展方面，直接点明议题，即“先概括后具体”，先整体轮廓， 后具体细节。“让事实本身说话”，则能达到更好的效果。

The compass（指南针）is one of the Four Great inventions of Ancient China. Before the compass was invented, people depended on the position of the sun and stars to tell them the direction when at sea, which only worked when it wasn’t cloudy. As early as the Warring States Period. Chinese people discovered that a magnet could show the south and the north, and, on the basis of this feature, they made a southward-pointing instrument that was the model of the compass. The instrument was made up of a smooth magnetic spoon and a copper（铜）plate carved with directions；the handle of the spoon pointed south. In the Song dynasty, people combined an artificially（人造地）magnetized compass with an azimuth（方位）plate to create proper compass.

In the Northern Song dynasty, the compass was being used for sailing. In the Southern Song dynasty, its use spread to Arabia and Europe, and Arabs called it “the Eye of Sailors”. The invention of the compass had great influence on sailing, opening up a new chapter（篇章）in the history of the world sailing. Thus, Zheng He made seven ocean journeys across seas to Southeast Asia and around Indian Ocean in the early Ming dynasty, Christopher Columbus discovered the New World, and Ferdinand Magellan sailed round the world.
