9．Rachel Carson was an American author and environmental protection scientist．"Silent Spring"was her most famous book．The idea for the book developed from a suggestion from a friend．Rachel's friend owned a protected area for birds．An airplane had flown over the area where the birds were kept and spread a powerful chemical called DDT．Many songbirds and harmless insects were killed by the DDT．
Miss Carson and other scientists were very concerned about the harmful effects of DDT and other insect-killing chemicals called pesticides （杀虫剂）．Rachel Carson tried to get many magazines interested in publishing a report about the subject．However，none would agree to publish anything about such a disputed （有争议的） subject．They said no one wanted to hear that industrial companies could cause great ecological damage．
Miss Carson believed the public needed to know about this important issue．She decided to write a book about it．In her book"Silent Spring"，Miss Carson questioned the right of industrial companies to pollute without considering the effects on the environment．Miss Carson argued that this kind of pollution would result in ever-decreasing populations of birds and other wildlife．She said this would lead to the loss of the wonderful sounds of nature．The chemical poisoning of the environment，she said，would cause a silent spring．
The chemical industry felt threatened．Industry spokesmen and other critics said the book was non-scientific and emotional．They misunderstood the message of the book．Miss Carson did not suggest that all pesticides be banned．She urged that control of these substances be given to biologists who could make informed decisions about the risks involved．
Support for the book increased．By the end of 1962，there were more than forty bills in state laws proposing to control pesticides．Finally，in November，1969，the United States government ruled that the use of DDT must stop in two years．
Rachel Carson did not live to see how her book influenced the government's decision to ban DDT．She died of breast cancer in 1964．

9．It is common and usual to see people freak out when they face challenges in their life．We all pass in different life problems and challenges．No one is free of life problems．Only a dead man faces no problem．As long as you are alive，challenges are everywhere．
How do you face problems and challenges in your life？Problems and challenges are the building blocks of your personality．They make you who you are．Besides，whether what happened in your life builds or destructs you depends on how you look at it．If you take your problems as troubles，they will be troubles and may cause destruction．If you take them as constructive tools，you are going to be built up on them．
Problems are everywhere．No one can avoid them．And they are good too．They open up a different look and opportunity if you are willing to see．When you face troubles，do not frustrate or freak out．Just cool yourself to think in a different direction．Think in a positive way．Every problem has its own good as well as bad sides．Focus on the good one．Look at the bright side．
Besides，there is always a good person，perhaps your mom or dad，or one of your friends，right beside you who can turn everything into your best if you are willing to turn to them．No matter what happens，they will be there to help you．Trust them and they will never let you down．All you need to know is that you are loved wherever you are．
