PART V FOLLOW UP EXERCISES 1．Paragraph A

After years of trial and error，Disney finally found the character he was looking for. This character，called“Mickey Mouse，”was first introduced in the cartoon Plane Crazy and later found ultimate fame in Steamboat t Willie，the first sound cartoon ever made and a great achievement for Disney．By 1930，after his fame had spread all over the world. Mickey was established as the cinema’s most popular cartoon character．Because Mickey was a moralist with a sense of fun，he became a character loved by all ages．In him，Walt Disney reached his peak of success. Paragraph B

Environmental protection will benefit US a lot．First，by making our air purer and water cleaner，We can improve our living condition．As we all know，a healthful living condition is essential to our work and study．Second，environmental protection does good for the younger generation．It not only improves our children’ health，but also teaches our children a good attitude toward the environment．Third，environmental protection saves our resources．Since we can recycle used materials instead of throwing them away．we can get more material but produce less waste． 2. There is only one child in many families in China，so many parents and grandparents love the child to such an extent that they do not allow them to do anything when they think there may be a slight chance of their child getting hurt· Many parents escort their child to school every morning．Therefore，when the child grows up，he still can’t do anything．

Look at the picture．The girl wants to learn to ride a bike，but her parents and grandparents wouldn’t let go．I think these parents should have let the girl ride the bike by herself．

It is bad for parents to love their children too much．If they help their children in everything，their children will always be unable to do their own work．When they grow up，these children will find that things are totally different in their working place．

Therefore，parents should 1et their children do things on their own． 3．a．A boy wants something very special from his father b．A favor may not be a favor at a11． c．I do play roles．
