A field trip is a journey by a group of people to a place away from {#blank#}1{#/blank#}（they）normal environment.

    The purpose of the trip is usually observation for {#blank#}2{#/blank#}(educate), non-experimental research or to provide students with experiences outside their everyday {#blank#}3{#/blank#}(activity), such as going {#blank#}4{#/blank#}(camp) with their teachers and classmates. The aim of this research is to observe the subject in its natural state and {#blank#}5{#/blank#}(possible) collect samples(标本). In western culture people first come across this method during school years {#blank#}6{#/blank#}classes are taken on school trips to visit a geographical feature of the landscape. Much of the early research into the natural sciences {#blank#}7{#/blank#}(be) of this form. Charles Darwin is considered to be {#blank#}8{#/blank#}important example of someone who has contributed {#blank#}9{#/blank#}science through the use of field trips.

    {#blank#}10{#/blank#}(reduce) risks and expenses, most school systems now have set up field trip procedures that consider the entire trip from estimation, approval to scheduling.

    Night after night, she'd lean down and push my long hair out of the way, then kiss my forehead. I don't remember {#blank#}1{#/blank#} it first started annoying me —her hands pushing my hair that way. But it did annoy me, for {#blank#}2{#/blank#} felt work-worn and rough against my young skin. Finally, one night, I shouted {#blank#}3{#/blank#} her, “Don't do that any more— your hands are too rough!” she didn't say anything in reply. {#blank#}4{#/blank#} never again did my mother close out my day with that familiar expression of love. Now, my own children are {#blank#}5{#/blank#}(grow) and gone. It was late on Thanksgiving Eve, as I slept in the bedroom of my youth, {#blank#}6{#/blank#} familiar hand hesitantly run across my face to brush the hair from my forehead. Then a kiss {#blank#}7{#/blank#}(gentle) touched my brow. In my memory, for the thousandth time, I recalled the night my young voice complained, “Don't do that any more — your hands are too rough!” {#blank#}8{#/blank#}(catch) Mom's hand in hand, I blurted out {#blank#}9{#/blank#} sorry I was for that night. I thought she'd remember as I did. But mom didn't know what I {#blank#}10{#/blank#} (talk) about. She had forgotten — and forgiven — long ago. That night, I fell asleep with a new appreciation for my gentle mother and her caring hands.

Journey to the Center of the Earth spoke of a trip to the centre of the earth through a volcano in Iceland. When Professor Otto Lindenbrock，his nephew and the guide they hired {#blank#}1{#/blank#}(reach) the volcano， they journeyed underground through a small cave. After many days， they came to a vast room {#blank#}2{#/blank#}a large ocean inside. The three men built a small boat and set sail.{#blank#}3{#/blank#} (sudden)， two dinosaurs rose to the surface and began to fight each other. The small boat was almost sunk by the dinosaurs {#blank#}4{#/blank#}they were able to get away.

They sailed to shore and explored the forest. They came across huge insects and many strange {#blank#}5{#/blank#}(creature). As they were wandering around， they noticed a man sitting against a tree in the {#blank#}6{#/blank#}(distant)—he was at least four meters tall. The men became afraid， and ran back to the boat.

The boat floated down with the water {#blank#}7{#/blank#} they could only hold on to the boat in terror. Finally， they reached the bottom of the hole. Then the water began to push them up. They floated upwards for miles. The water rushed beneath them， {#blank#}8{#/blank#}(push) them out into the sunlight. They now found {#blank#}9{#/blank#}(they) in a volcano in Italy—their adventure was over，but a new one was about {#blank#}10{#/blank#}(begin).
