语法选择 Teachers say that the digital(数字) age has had a good influence and a not﹣so﹣good influence on American teenagers. More than 2,000 middle and high school teachers took 1 online survey. Researchers also spoke with teachers in some groups. Most teachers think the Internet and digital search tools have had a mostly positive influence on their students' research habits and skills.2 at the same time,some teachers also point out some problems in teenagers' using digital search tools.
The Pew Internet Project did the survey with the College Board and the National Writing Project. Judy Buchanan is the director 3 the National Writing Project and a co﹣writer of the report. She says digital research tools are helping students learn more,and learn4 . "5 teachers and students really welcome these tools because they make learning 6 . And the goal is to really help students become creators of 7 meaningful,and not just users of the online information. "
But one problem the survey found is that these technologies make teenagers have short attention spans. As there is huge amount of information about different subjects on the Internet,teenagers' attention is 8 drawn away from their research.
9 problem the survey found is that many students trust the information they find on the Internet too much. Judy Buchanan says these students have not developed the skills to judge the online information. They need to learn a lot to tell 10 the information is believable. It's something that really has to be noticed.
One more problem the survey found is something that might not seem like a problem at all:being able to quickly find information online. Many students think "doing research" now means just 11 quick search on Google. Teachers say the result is a drop in the wish and ability of their students to work hard 12 answers. That is ,they are overly dependent on search engines and do not make enough use of printed books or research librarians.
Many teachers also say that the Internet makes 13 easy for students to copy work 14 by others instead of using15 own abilities.
