When one door of happiness closes, another opens. However, we often look at the 1 door so long that we can't see the one that has been opened for us. It's true that we don't know 2 we've got until we lose it, and it's also true that we don't know what we've been 3 until it goes away.

    Giving someone all your 4 doesn't mean that they'll love you back. Don't expect love in return. Just 5 for it to grow in their hearts.

    There are many moments in life when you miss someone so much that you want to bring them into your 6 and hug them for real! Dream what you want to dream, go where you want to go, and 7 what you want to be, 8 you have only one life and one chance to do all the things you want to do.

    Happiness lies in those who have cried, those who have been hurt, those who have searched, and those who have tried, for only they can understand the 9 of their lives. The 10 future will always be based on a forgotten past. You can't go on well in your life until you let your past failure and heartaches go.

    The world is in danger. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 860 remain(剩余). The others have been destroyed(破坏) by man. We are changing the earth, the air, the water and everything that grows and lives. We can't live without these things. If we continue doing like this, we will destroy ourselves.

    What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation(对自然环境的保护) is necessary. Many are helping to save our world. They plant trees and protect animals in forest. In a small town in the United States, a large group of volunteers cleaned the banks of their rivers. Young people may hear about conservation through a record called No One's Going to Change Our World. It was made by the Beatles, Cliff Richard and other singers. The money from it will help to protect wild animals.

    We always think that it's OK for us to leave our plants home during our vacation as plants won't scream like pets, right?

    A recent study done by a group of scientists at the Tel Aviv University has discovered that some plants will scream when they are under stress.

    The research was carried out on tomato plants and tobacco plants by cutting their stems (茎) and depriving (剥夺) them of water. A microphone was placed 10cm away from them. When their stems were cut, the plants started "screaming" between 20 and 100 kilohertz, and the scientists guess that this scream is probably meant to warn other plants nearby.

    When the tomato plants' stems were cut, 25 ultrasonic (超声的) pain sounds were recorded in an hour, and at the same time, 15 ultrasonic pain sounds were recorded from the tobacco plants. When they were deprived of water, the tomato plants recorded even more pain sounds with 35 pain sounds in an hour while the tobacco plants recorded about 11 pain sounds.

    The plants also acted differently to different kinds of stresses. For example, the tobacco plants gave out a stronger "scream" when they were deprived of water than when their stems were cut. But plants that were in no immediate (立刻的) danger gave out less than one ultrasonic sound per hour.

    The group of scientists said that plants are not as quiet as we had always thought, but in fact their voices are so high-pitched that we just can't hear them.

    Last year, another study has found out that plants feel pain when they are touched or hurt and they will give off a terrible smell.

    Started in 1636, Harvard University is the oldest of all the colleges and universities in the United States. {#blank#}1{#/blank#}

    In the early years, these schools were much alike. Only young men went to college. {#blank#}2{#/blank#} Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated, most of them became ministers or teachers.

    In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard's law school. {#blank#}3{#/blank#} Soon it began teaching American history.

    As knowledge increased, Harvard and other colleges began to teach many new subjects. {#blank#}4{#/blank#}

    Today, there are many different kinds of colleges and universities. {#blank#}5{#/blank#} There's so much to learn that one kind of school can't offer it all.

A. In 1825. besides Latin and Greek, Harvard began teaching modern languages, such as French and German.

B. Most of them are made up of smaller schools

C. Yale, Princeton and Columbia were opened soon after Harvard

D Students were allowed to choose the subjects that interested them

E. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew
