Bob: Hi, Linda. What are you doing?
Linda: Hi Bob. I         (prepare) for the test tomorrow.
Bob: But        are you here in the garden?
Linda: Well, the library is full and the classroom is too         (noise).Are you ready for the test?
Bob: I am afraid not. Ｉfeel very nervous. We don’t have much time          (leave).
Linda: We can prepare together. Maybe that can help.
Bob: Good idea! How many units will be included?
Linda: Three. They are unit4, unt5 and unit 6.
Bob: Really? I             (think) unit 6 would not be covered.
Linda: It will. Now let’s ask each            questions. You go first.
Bob: All right. Name three             (Europe) countries.
Linda: Easy. France, Germany and Italy. I can even say more.
Bob: It seems you are well prepared. Now it’s your turn            （ask）questions.
Linda: OK. What are the seven           of the world?
Bob: Asia, Europe, Africa, and ….Er, I really can’t remember             all.
Linda: Don’t worry. You still have time.
