I feel quite sure the chemistry test that we’re going to have tomorrow. The teacher has already told us exact what to study and I think my grades on homework has been good．In a fact, I think chemistry has always been one of the subjects that I enjoy it most. Susan and I had already spent two hours review pages 115-140 tonight. We are going to devote another hour to practise with some of the sample(实例) problem. Then I will ready for the test.
