所谓的语文学习，主要是学习表达能力和理解能力。表达能力包括口语表达能力和书面表达能力，表达要求能够做到逻辑清晰，语言流畅准确。
语言学习的考核点由表达能力和修辞能力构成。接下来我就来具体学习一下表达篇的内容吧！
Verb Voice
动词的语态
Verbs in English have voice, which refers to the relationship between the subject of the sentence and the verb.
动词在英语中有语态，指的是句中主语和动词的关系。
Examples of Verb Voice:
动词语态的例子：
There are two verb voices in English:
英语中动词的语态有两种：
Active Voice-when the subject of the sentence the person or thing doing the action of the verb or in the state expressed by the verb. This is the voice with which we are most familiar-the subject performs the action of the sentence.
主动态-句中的主语的人或物做出动作或是处于动词所表述的状态，这就是我们最熟悉的主动态-句中主语是动作的执行者。
Passive Voice-when the subject of the sentence is being acted upon. The subject of the sentence is not performing the action. Instead, it is receiving the action.
被动态-句中的主语是动作的承受者。主语不执行动作，而是接受动作。
Most writers do not use passive voice. Passive voice should only be used when you need to emphasize the thing that is being acted upon.
很多人不使用被动态。只有需要强调接受动作的事物时，才使用被动态。
To write a sentence in the passive voice, you must use an auxiliary verb, or "helping" verb.
用被动态写句子，必须使用助动词。
Examples of sentences written in active voice:
主动态的例句：
1) Joseph threw the ball through the neighbor's window.
1）Joseph把球扔进了邻居家的窗户。
2) Alyssa drank the last bottle of water.
2）Alyssa喝了最后一瓶水。
3) Katie read the library book.
3）Katie阅读图书馆的书。
4) Pamela walks her dog Bucky.
4）Pamela溜他的狗Bucky。
5) The class watched a movie about frogs.
5）全班同学看了一部有关青蛙的电影。
