What Do No. 5 High School Students
Do in Their Free Time
Last month we asked our students about their free time activities. Our questions were about exercise, use of the Internet and watching TV. Here are the results.
Task 3: Careful reading(paragragh1)
What were their questions about
bar chart
pie chart
line graph
table
Here are four common ways to visually present data. Do you know their names
The report uses pie charts to present the collected data. Look at the following charts and figure out what activities the data is about.
Complete the pie charts according to the report.
We found that only fifteen percent of our students exercise every day. Forty-five percent exercise four to six times a week. Twenty percent exercise only one to three times a week. And twenty percent do not exercise at all!
We all know that many students often go online, but we were surprised that ninety percent of them use the Internet every day. The other ten percent use it at least three or four times a week. Most students use it for fun and not for homework.
Pay attention to the percentages and frequency phrases in the text.
Task 3: Careful reading(paragraghs2-4)
The answers to our questions about watching television were also interesting. Only two percent of the students watch TV one to three times a week. Thirteen percent watch TV four to six times a week. And eighty-five percent watch TV every day! Although many students like to watch sports, game shows are the most popular.
Complete the pie charts according to the report.
