It is summer vacation and schools are closed. During the summer some children stay at home, watch TV and play with their friends. Some take part in a neighborhood sports, and some go to camp.
A camp is a summer vacation place for children. Campers take part in sports activities like swimming, boating, or riding horses. They also take part in other activities like playing games and painting pictures. In the evening they sit around a campfire, cook hot dogs, sign songs, or tell ghost stories. Some camps combine (结合) special programs with the usual camp activities. There are camps to teach tennis, basketball or other sports. There are camps to teach science or music. There are also camps for intelligent children, fat children, or handicapped (残疾的) children.
Now there are computer camps. Denison Bollay owns a computer camp. At his camp children learn how to use computers. Computers are very important today, so children must learn how to use them. Many schools have computers for the students to use, but not all the students know how to use them. Some schools do not have a program to teach the students. So, Bollay’s camp combines important computer learning with summer fun.
Bollay’s campers have three computer classes a day. They study computer language and programming. After a few days of classes, each camper designs a computer program. Some campers design programs to help parents at home. Others design programs to help students at school. Some campers design computer games. Bollay’s campers must also choose two camp activities a day. They can choose an activity like swimming, boating, painting or horseback riding. In their free time, the campers can choose any activity. What do they do in their free time? Well, they do not swim, and they do not ride horses. They play games on the computers.

二、 课文精讲
1.It is on this arable land that the farmers produce food for the whole population of China.
正是在这些耕地上农民们生产粮食供给全中国的人民吃。
此处用了强调句式，其结构是：It is/was + 被强调部分 + that/who …, 本句被强调的部分是on this arable land, 强调农民生产粮食的地点。
2.To make as much use of the land as possible, two or more crops are planted each year where possible.
为了尽可能充分地利用土地，在可能的地方每年种两种或多种作物。
此处是不定式短语to make as much use of the land as possible作状语；make use of意思为“利用”，相当于动词use, 其中的use为不可数名词；where possible是一种省略形式，其完整形式为where it is possible.
3.It was developed using a technique known as GM.
它（西红柿）是用一种GM的技术培育出来的。
从using到句末为分词短语作方式状语；known as GM为过去分词短语作后置定语修饰technique, 表示被动的概念。
4.He collected information, studied it, did experiments and learnt from the experiences of farmers.
他收集信息，研究信息，做实验并从农民的经历中学习。
此处为一个主语带着四个并列的谓语动词，表示一系列的动作。即：collected, studied, did, learnt 在这种结构中，要求各个谓语动词的形式保持一致。

四、 语法讲解
主谓一致（二）
5. 当or, either … or …, neither … nor …, not only … but also …, not … but…等连接两个并列主语时，谓语动词要与离它最近的那个主语保持一致。这在语法上叫做邻近原则。
