4．We cannot be sure when we’ll be able to travel in space．
5．They are worried about whether robots will be smarter than people．
6．We cannot be sure whether the future will be better．
T：Now let’s do the exercise in Part 3．The main purpose of this exercise is to
help you understand the differences between a Noun Clause and an Attributive C1ause．Who’d like to tell me the differences between them?
S：I’d Iike to try．A Noun Clause is used as a subject，object，predicative or op-
positive in the main clause．An Attributive Clause serves as an attribute to
some noun or pronoun in the main clause，and it is often placed after this noun or pronoun．The Attributive Clause is introduced by the relative pronouns and the relative adverbs．
T：Very good．Sit down please．Now please read the sentences in Part 3 first．Then identify the type of clause in the sentences．If it is a Noun C1ause，write“NC”；if it is an Attributive C1ause，write“AC”．Are you clear?
Ss：Yes．
T：Now you are given three minutes to prepare it．
(Three minutes 1ater，ask five students to say their answers one by one．)
Suggested answers!
1．NC 2．NC 3．AC 4．AC 5．NC
T：Well done．Now look at Part 4．Re-write the sentences so that they be-come the type of noun clauses in brackets．If you have any problem，you can look at the example．
(Teacher gives them four minutes to finish it．After that, ask the students to read out their sentences．)
Suggested answers：
1．We must make sure what is needed to open an online store．
2．How we can develop transportation without polluting the environment is still a problem．
3．We don’t know when we’ll have the medicine that can cure any disease．
4．All I want to know is whose book you are reading．
