Of all living creatures on earth, insects are the most plentiful. Some　 36　 are very useful to man, for example, bees,　 37　 we get honey and wax, and silkworms, which　 38　 us with silk. Other varieties,　 39　 , are extremely harmful, and do a great　 40　 of damage, especially to crops. Locusts （蝗虫） are perhaps the most dangerous of all,　 41　 they will eat almost any green　 42　 , and when millions of them　 43　 on cultivated land（耕地）they soon leave it　 44　 . In some countries they are the farmer’s　 45　 enemy. Another nuisance is the common　 46　 , not only because it　 47　 us indoors and out - of- doors, but because it spreads diseases.

　　Scientists have given much time and　 48　 to the study of insects. It needs the most careful and　 49　 observation. Thanks　 50　 their discoveries we now know almost all　 51　 is to be known about the habits of these hardworking insects, bees and ants, which live in　 52　 better planned in some ways than our　　53　 . But the most valuable work has been done in trying to give　 54　 to men, animals and crops from the　 55　 which insects cause.

Dear XXX,　

As we drove off from Columbia, I wanted to write a letter to you to tell you all that is on my mind.

Do your best in classes, but don’t let pressure get to you. If you graduate and learn something in your four years, we would feel happy. Your Columbia degree will take you far, even if you don’t graduate with honors. So please don't give yourself pressure. The only thing that matters is that you learned. The only measurement you should use is that you tried.

Most importantly, make friends and be happy. College friends are often the best in life, because during college you are closer to them physically than to your family. Also, going through independence and adulthood is a natural bonding (结合的) experience. Pick a few friends and become really close to them — pick the ones who are genuine and sincere to you. Don’t worry about their hobbies, grades, looks, or even personalities. If you think you like someone, tell her. You have very little to lose. People are not perfect, so as long as they are genuine and sincere, trust them and be good to them. They will give back. This is my secret of success — that I am genuine with people and trust them (unless they do something to lose my trust).

College is the four years where you have:

　　•the greatest amount of free time

　　•the first chance to be independent

　　•the most flexibility to change

　　•the lowest risk for making mistakes

So please treasure your college years – make the best of your free time, become an independent thinker in control of your destiny. May Columbia become the happiest four years in your life, and may you blossom into just what you dream to be.

                                                                   Love,

                                                                  XXX
