I love exploring nature. During weekends, I often go to the nearby forest.
As I walk along the path, the fresh air makes me feel energetic. I hear birds singing in the trees, as if they are welcoming me.The field is covered with colourful wildflowers. I stop to enjoy them and sometimes take pictures. Once, I saw a small stream. The clear water is running over the stones, making a pleasant sound.
Exploring nature helps me forget about study stress. It also makes me realize how important it is to protect our environment. I hope more people can experience the beauty of nature.

二、阅读理解
Bees spend lots of time looking for food. But not all the bees in the hive (蜂巢) have this work. Bees can be divided into three kinds—a queen bee, drones (雄蜂) and worker bees. The queen bee is very important. She is the mother of all the bees that live in the hive. Worker bees do all the other work in the hive. Besides looking for food, they make and clean the hive. They also look after the queen and protect her.
Bees make dance-like movements inside the hive to send messages about food. They use different movements to give different information. They tell where food can be found and how far away it is from the hive. Bees can even share how much food there is and how good it is.
And surprisingly, a new study has found that a group of bees could generate an amazing total of electricity by beating their wings more than 200 times per second. And the amount (数量) of electricity could reach 100 to 1,000 V (伏). That's eight times greater than the electricity a storm cloud can produce.
Scientists found that the thicker a cloud of bees is, the more electricity it generates. Based on these findings, the team recorded that bees—which group together to form a huge, thick cloud of bees—could have an influence similar to that of a storm. Further research is needed to find out how electricity influences the bees and their environment.

一、朗读技巧
名词与动词同形的单词重音
在英语中，当一个单词既可作名词又可作动词时，名词和动词的重音往往有所不同。这是一种常见的读音规律，一般遵循以下规则：
1.名词重音在前：当单词作名词使用时，重音通常在第一个音节上。如：
record /'rek d/ n. 记录，记载
present /p'rez( )nt/ n. 礼物，赠品
2.动词重音在后：当单词作动词使用时，重音通常在第二个音节上。如：
record /r 'k d/ v. 记录，记载
present /pr 'zent/ v. 颁发，赠送
二、口语特训
