1 Revision
（3mins) Individual work Let the Ss read out their sentences with
attributive clause.
T: Hi, boys and girls! Let’s begin our class.
Do you still remember the grammar we
learned in the last period?
T: Have you written five sentences with
attributive clause?
T: Who wants to show us? Don’t be afraid
of making mistakes.
T: That’s terrific! You all made up so nice
sentences. Read out their sentences with
attributive clause.
Ss:定语从句。
Ss: Yes.
S1: Look at this photo. The boy
who/that is next to me is my cousin.
S2: Oh, my god! The book
which/that I borrowed from the
school library is lost.
S3: The man who has two children
will be our new P.E teacher.
S4:… 可能有的学生写的句子会出现从句的谓语与主句的人称不一致的错误，老师要加以改正。另外，目前所学的定语从句里，关系代词在从句中都是作主语。老师也可以有意识地提一下：关系代词还可以做其他成分。
2 Pre-listening
(7mins) Group work
Individual work Step 1: Let the Ss discuss how the spaceships
work during the flight to lead to 1a.
T: We know spaceships play an important
part in exploring the outer space. Do you
know how the spaceships work during the
flight? Discuss in groups for a while, and
then report to the class.
T: Do you have any ideas, Group 1?
T: Group 2?
T: Good ideas! Which group is right? Let’s
keep it as a secret. After listening to 1a, you
will get the answer.
Step 2: Let the Ss read the statements in 1b,
tick the possibilities. Discuss how the spaceships work
during the flight.
S1: We think the spaceships are
controlled by the astronauts.
S2: We don’t agree. We think the
spaceships are controlled by
computers.
S3: …
Read the statements in 1b and tick
the possibilities. 如果学生不能用英语来讨论飞船是怎样工作的，也可以用汉语来表达。
T: Maybe you know much about computers.
Try to predict what computers can do to
spaceships. Tick what you think may
happen.
让学生根据已有经验来预测未知的领域有助于激发他们听的欲望，并更专注于特定的内容。
3 While-listening
(4mins) Individual work Let the Ss listen to 1a and get the answers to
discussion and prediction. Check the
answers. Finish 1b.
T: Now, you may be eager to know which
group is right and whether you predicted
correctly. Now, it’s time to find out the
answers. Listen to 1a carefully and check
the answers. When you finish, put up your
hand.
T: Which group is right, do you know?
Listen to 1a and get the answers to
discussion and prediction. Check the
answers. Finish 1b.
S1: Group 1.
S2: Group 2. 因为学生还没有学习electronic这个单词，所以难以得到正确的答案，可以等到他们阅读1a后再揭晓。
