Activity: An interview
• Suppose you are a reporter. Now you are
interviewing Mr./Miss Computer.
• Work with your group members to think
out some interesting questions.
• Sample questions:
*What is your newest function(功能)?
*Can you say something about your future plan?
*What do you like to eat?
*What are your hobbies?
• Work with your partners to practise
this interview. One acts as Mr./Miss
Computer, and the other the reporters.
• Sentence focus:
• 1.I follow instructions from cards with holes.我执
行穿孔卡的命令。
• 2. My real father was Alan Turing, who in 1936
wrote a book to describe how computers could be
made to work, and built a “universal machine” to
solve any mathematical problem.
• 3.As the years have gone by, I have been made
smaller and smaller.
• as此处引导时间状语从句,意为“随着…”;
• 4. I was always so lonely standing there by
myself, …
standing there by myself是v.ing形式做伴随状语
• 5 . … they gave me a family connected by a

connected by a network是过去分词短语做定语,
修饰family, 相当于定从:which was connected
by a network.
• 6. At about the same time we learned to talk to
humans using BASIC.
using BASIC是v.ing形式做方式状语,表示“通
过用…”; 相当于“by using …”。
