老师：Hello, everyone. Welcome to English class. In this class, you will identify and summarize the form of the predictive class. You will get to know the meaning of the predictive clause and also you will use the predictive clause to talk about science and scientists. Are you ready? Let's get started.
老师：First, let's review what we have Learned so far in this unit. We have read a passage about how John's notifits king cholera. From the reading, we know when an outbreak of a cholera hit Europe, millions of people died from the disease. John Snow determined to destroy cholera once and for all. He collected data and analyzed results. He concluded that the disease was caused by germs in water. Thanks to Zhijohn's know, we now know how to prevent cholera.

老师：Now, we have two sentences here. Let's read them one by one. Sentence No. 1, it seems that science is all around us. Sentence No. 2, understanding science and pushing the boundaries of science is what makes me satisfied. Can you please find and underline the predictive clauses? Yes, the first one, you're right, the predictive clause is that science is all around us. And how about the second one? Right, the predictive clause is what makes me satisfied.
