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.

    Many of my friends like fall and take it as their favorite season. Last weekend, I went outdoors and soon {#blank#}1{#/blank#}(find) a deeper appreciation for this season.

    The change of leaf colors is a common reason given {#blank#}2{#/blank#}the love of fall. Each tree reacts{#blank#}3{#/blank#}(different) to the change of the season. Some shed their leaves in hopes of reproducing; however, other {#blank#}4{#/blank#}(tree) remain green for as long as possible to gain additional energy from the sun to survive the winter. This effect {#blank#}5{#/blank#}(call) the flight-or-fight response.

    Fall is a time of{#blank#}6{#/blank#}(reflect) and preparation for the year ahead. I have found a meaning of fall for me. I'm {#blank#}7{#/blank#}18-year-old boy in the final year of high school and my life is a work in progress. There are times I want to give up, but then I look around me and realize life keeps {#blank#}8{#/blank#}(move).The natural cycle of life is beautiful and doesn't stop growing so I have to learn to keep up.

The meaning of fall is different for each person. I encourage you {#blank#}9{#/blank#}(go) out to follow some path or sidewalk and discover {#blank#}10{#/blank#}fall means to you.

    It is sad but true that people die in earthquakes{#blank#}1{#/blank#}falling furniture and bricks. Earthquake{#blank#}2{#/blank#}(safe) is very important and there is more to it{#blank#}3{#/blank#}just keeping buildings from falling down. So if your home is in an earthquake area, you should prepare carefully before the earthquake{#blank#}4{#/blank#}(come).

    First, make sure you buy a house which is earthquake safe. All pipes should be fixed to the walls and all walls should be{#blank#}5{#/blank#}(especial) thick and strong. Make sure the building has no{#blank#}6{#/blank#}(break) windows and is well repaired.

    Second, look at the objects in your house. Objects{#blank#}7{#/blank#}computers, televisions and lamps can be tied to tables or{#blank#}8{#/blank#}(stick) to them so they won't easily move around. The cupboards,{#blank#}9{#/blank#}many small things are stored, should have strong doors. Always remember,{#blank#}10{#/blank#}(good) safe than sorry.

    One Sunday morning in August I went to a local music festival. I left it early because I had an appointment{#blank#}1{#/blank#}(late) that day. My friends walked me to the bus stop and waited with me{#blank#}2{#/blank#} the bus arrived. I got on the bus and found a seat near the back，and then I noticed a man{#blank#}3{#/blank#}(sit) at the front. He {#blank#}4{#/blank#}(pretend) that a tiger toy was real and giving it a voice. He must be{#blank#}5{#/blank#}(mental) disabled.

    Behind him were other people to {#blank#}6{#/blank#} he was trying to talk，but after some minutes {#blank#}7{#/blank#} walked away and sat near me，looking annoyed.

    I didn't want to be laughed at for talking to him but I didn't like leaving him {#blank#}8{#/blank#} his own either.

    After a while I rose from my seat and walked to the front of the bus. I sat next to the man and introduced myself. We had {#blank#}9{#/blank#} amazing conversation. He got off the bus before me and I felt very happy the rest of the way home.

    I'm glad I made the choice. It made {#blank#}10{#/blank#} of us feel good.
