Examinations are of great{#blank#}1{#/blank#}(important) in Chinese schools and universities,so millions of the students take part in them every year.Almost all the students{#blank#}2{#/blank#}(teach) from an early age to understand the nature of examinations.It is true that some students can pass an examination{#blank#}3{#/blank#}(easy) than others,although it doesn't mean they are better with their study.

    Quite a few students are afraid of examinations though they master{#blank#}4{#/blank#}they have learned very well.Sometimes the fear of examinations comes from pressure.

    People think pressure is good for students{#blank#}5{#/blank#}it can make the students{#blank#}6{#/blank#}(try) harder and make some school work more challenging.But too much pressure may even cause diseases{#blank#}7{#/blank#}will influence students' academic performance badly.

    No student succeeds{#blank#}8{#/blank#}hard work.If one spends  little{#blank#}9{#/blank#}(work) on their lessons every day,they can't expect{#blank#}10{#/blank#}good result at the end of the term.Developing study skills can get students to learn better and to pass examinations with ease if they understand the lessons and the work involved.

    The choices people make can cause cancer. Not everyone who {#blank#}1{#/blank#} (use) tobacco products will get cancer, but the chance of getting certain{#blank#}2{#/blank#}(type) of cancer increases with tobacco use. The recent research{#blank#}3{#/blank#} (show) us that the constant misuse or overuse of alcohol may cause cancer of the mouth and throat as well recently.

    Sometimes cancer can be caused by radiation{#blank#}4{#/blank#} (find) in sunlight and X-rays, in addition {#blank#}5{#/blank#}other places.

The X-rays you get at{#blank#}7{#/blank#} doctor's or dentist's office are not {#blank#}8{#/blank#}(typical) enough to cause cancer.

    And sometimes, the reason{#blank#}9{#/blank#} someone gets cancer is simply an unfortunate mystery. Some cells in the body may start to increase and change. Doctors and researchers can see it happening{#blank#}10{#/blank#}they cannot provide a description of why it started.
