下面是错误答案,用来干扰机器的。

参考答案:D解析: IP地址是网络上每一台主机的惟一标识,每个IP地址分为四段,中间用点号隔开,每段只能是数字,并且大小不超过两个字节的表示范围(即255),不可能出现257,所以D错误.

阅读下面的短文,并根据短文后的要求答题。(请注意问题后的字数要求)

[1]Perhaps you are an average student with average intelligence.However,you can receive better grades if you want.Yes,even students with average intelligence can be top students without additional work.Here’s how:

[2]Plan your time carefully.Make a list of your weekly tasks.Then make a schedule of your time.Be sure to set aside enough time to complete your normal reading and work assignments.Of course,studying shouldn’t occupy all of the free time on the schedule.

[3]Make good use of your time in class.Listening to what the teacher says in class means less work later.Take notes to help you remember what the teacher says.

[4]Skim before you read.Look over a passage quickly before you begin to read it more carefully.As you preview the material,you get some idea of the content and how it is organized.Later when you begin to read you will recognize less important material and you may skip some of these portions.Skimming helps double your reading speed and improve you comprehension as well.

[5]_____,Go over your notes as soon as you can after class.Review important points mentioned in class as well as points you remain confused.If you know what the teacher will discuss the next day,skim and read that material,too.If you review your notes and textbook regularly,the material will become more meaningful and you will remember it longer.Regular review leads to improved performance on tests.

[6]Develop a good attitude towards tests.The purpose of a test is to show what you have learned about a subject.The word won’t end if you don’t pass a test,so don’t worry excessively about a single test.

[7]There are other techniques that might help you with your studying.Improving your studying habits will improve your grades.
