一篇高中英语阅读理解
What is interesting to me?
You can connect almost any topic to science.Your topic could be plants,worms,dogs,the sky,or something else.If you cannot think of a topic,search books or the Internet for ideas.Seek help from your teacher or a librarian.Your parents may have some good thoughts too.
What question do I have about this topic?
A great science project always includes an experiment.Make sure that your question can be answered through an experiment.Here are some examples of questions:Does the amount of light have an effect on how fast plants grow?How much salt is in different kinds of cookies sold sat the store?Why does the sky change color at different times of the day?
How much time do I have before the science fair?
A science fair to be held in two weeks will not give you time for some experiments,such as growing plaints.carefully plan your project so that you allow enough time to perform your experiment accurately.
What do I think is the answer to my question?
Why do I think this?The answer you choose is your hypothesis.You will prove it right or wrong by performing an experiment.If you were to think about the sky question,your hypothesis might be that the color of the sky is related to the position of the sun.
How can I prove my hypothesis?
This is where the experiment comes in.You have to test your hypothesis.If you wanted to find out how light affects plant growth,you could plant seeds in a number of containers.Then you could expose the plants to different amounts of light and compare the growth rates.
How can I present my results?
You might display your question and hypothesis on poster boards.You might then add pictures and graphs.A great science project also states a conclusion.A conclusion of the plant experiment might be The plants that got the most light grew the fastest.
When you have finished your project,you may have more questions.A great science project makes you want to learn even more.
63.A great science project always includes ________.
A.plants in pots B.an experiment C.results D.poster boards

C.make a chart to explain your steps D.display your hypothesis to prove
答案是BCBA,为什么最后一个不选C.How much time那段不是有carefully plan your project so that you allow enough time to perform your experiment accurately.难道实验前不应该先列出步骤规划一下么

carefully plan your project so that you allow enough time to perform your experiment accurately.
说明你要认真计划一下你的项目使你的实验更加精确.
归根结底还是要使实验精确
所以实验是王道,由精确试验得出正确结论
c项的话,是用一张图表来说明你的实验步骤,人家要的是结论不是步骤.
