Dear Jim，

Yours，

Kids love the all-knowing Google.Your kids likely use Google to help them find everything from information for homework assignments，to funny cat videos，and everything in between.Sometimes kids can take a “wrong turn” on Google and end up in a dark part of the Internet where they shouldn’t be.Thankfully，Google has some parental control features that parents can implement to at least help reduce the volume(量) of crap(废物) that ends up in search results，which can enable you to help keep your curious kids from ending up on the wrong side of the tracks.What is Google SafeSearch？Google SafeSearch is one of the primary parental control options offered by Google to help parents police search results.SafeSearch helps to filter explicit(明确的) content out of search results.It is mainly designed to target sexually explicit material (images and videos) and not violent content.
How to enable Google SafeSearch？1.From the “Search Settings” preferences page，place a check in the box with the label “Filter explicit results”.2.To lock this setting so that your child can’t change it，click the “Lock SafeSearch” link.If you are not already logged into your Google account，you will need to do so in order to lock SafeSearch to the “on” position.Enable SafeSearch on mobile devices.In addition to your computer，you will probably also want to enable SafeSearch on any mobile device that your child uses regularly.For instructions on how to enable SafeSearch on a variety of mobile devices，check out Google’s SafeSearch Mobile support page.As we all know，kids are going to be kids and try to test their boundaries.We put up one roadblock and they go around it.It’s a constant cat and mouse game and there will always be some Internet door that we as parents forget to lock，and that will be the one that the kids get through，but we do the best we can.1.Which of the following are kids NOT likely to use Google to do?
A.To find information for homework assignments.
B.To find everything except information and funny cat videos.
C.To find funny cat videos on the Internet.
D.To find everything between information and funny cat videos.细节理解题。根据第一段第二句“Your kids likely use Google to help them find everything from information for homework assignments，to funny cat videos，and everything in between.”可知，孩子很喜欢使用Google搜索各种信息，包括滑稽的猫的视频。故B项正确。√ 答案 解析12342.What does the underlined “options” in Paragraph 2 mean?
A.Judgments. B.Uses.
C.Functions. D.Choices.词义猜测题。根据该划线词所在句“Google SafeSearch is one of the primary parental control options offered by Google to help parents police search results.”可知，实际上有很多类似的搜索控制的程序，Google SafeSearch只是父母的一种选择而已。option与choice同义。故D项正确。√ 答案 解析12343.What’s the first thing you’d do before setting Google SafeSearch?
A.Sign up and log into your Google account.
B.Find the “Search Settings” preferences page.
C.Find the label “Filter explicit results”.
D.Click the “Lock SafeSearch” link.推理判断题。根据第三段最后一句“If you are not already logged into your Google account，you will need to do so in order to lock SafeSearch to the ‘on’ position.”可知，如果你没有登录Google的账户，那么你就要先注册一个账号。故A项正确。√ 答案 解析12344.How do you enable SafeSearch on mobile devices?
A.Read the instructions of the related mobile devices directly.
B.Look for some Internet door to be sure we parents did not forget to lock it.
C.Check out Google’s SafeSearch Mobile support page for instructions.
D.Check in the box with the label any mobile devices. 答案 解析细节理解题。根据最后一段第三句“For instructions on how to enable SafeSearch on a variety of mobile devices，check out Google’s SafeSearch Mobile support page.”可知，要想在移动设备上使用SafeSearch，就要登录相关的网页查找使用说明。故C项正确。1234√Ⅱ. 七选五(2016·四川广元中学段考)
