【知识点详解】
在高中英语Unit2《The Olympic Games》中，语法巩固训练主要涉及的是将来时的被动语态。将来时的被动语态是英语中一个重要的语法结构，它用于表达一个动作将在未来由某个不确定的人或事物执行，并且这个动作的承受者是句子的主语。
一、将来时的被动语态构成：
1) 一般现在时被动语态（am/is/are done）和一般过去时被动语态(was/were done)是基础，用来描述当前或过去的动作。
2) 改写句子为被动语态的练习题：
- 1. 原句：She often waters the flowers every morning. 被动语态：The flowers are often watered by her every morning.
- 2. 原句：He invites me to the party. 被动语态：I am invited to the party by him.
- 3. 原句：The teacher blamed him for his being late yesterday. 被动语态：He was blamed by the teacher for his being late yesterday.
- 4. 原句：I saw them swimming in the sea. 被动语态：They were seen swimming in the sea by me.
3) 将来时的被动语态(will/shall/be going to + be done)：
- 5. 原句：We will send him there tomorrow. 被动语态：He will be sent there by us tomorrow.
- 6. 原句：The rabbits will eat the carrots. 被动语态：The carrots will be eaten by the rabbits.
- 7. 原句：They will finish this project in five years. 被动语态：This project will be finished by them in five years.
- 8. 原句：They are going to encourage children to take more exercise. 被动语态：Children are going to be encouraged to take more exercise by them.
- 9. 原句：The students are going to clean the classroom after school. 被动语态：The classroom is going to be cleaned by the students after school.
- 10. 原句：The people of Beijing will plant more trees and build new roads. 被动语态：More trees will be planted and new roads will be built by the people of Beijing.
二、单项选择题：
1. 原句：The Chinese food _________ to be the healthiest in the world. 此题考察一般现在时的被动语态，答案是C. is considered。
2. 原句：John _______, for he went swimming yesterday without permission. 此题考察一般过去时的被动语态，答案是D. was punished。
3. 原句：The work _________ soon. 此题考察一般将来时的被动语态，答案是A. will be finished。
4. 原句：All those old buildings __________ down tomorrow. 此题考察一般将来时的被动语态，答案是A. will be knocked。
5. 原句：The mistakes in the exercises will __________ the teacher. 此题考察一般将来时的被动语态，答案是C. be crossed by。
6. 原句：It is said that a new robot _______by him in a few days. 此题考察一般将来时的被动语态，答案是C. will be designed。
7. 原句：I ________ if I finish the work within one... 此题可能是不完整的，但如果是考察被动语态，答案可能是C. will be praised（假设完整句子是“I will be praised if I finish the work within one day.”）。
通过以上解析，我们可以看到，将来时的被动语态主要用于表示尚未发生的动作，其中主语是动作的承受者，而非执行者。同时，我们还复习了一般现在时、一般过去时和一般将来时的被动语态的构造以及它们在实际语境中的应用。
