Period 6 Summing Up，Learning Tip and Assessment
教学内容分析
This is the last teaching period of this unit，so the emphasis should be placed on going over and summarizing what has been learned in this unit.It includes the following parts：Summing Up，Learning Tip，Checking Yourself and some other consolidation exercises.
Summing Up summarizes the whole unit from the aspects of topics and vocabulary and grammar.The teacher can first use this part to let students sum up what they have learned in this unit and then let them find out what they can't understand very well.
Learning Tip gives students instructions on which kind of nouns begin with a capital letter.Let the students think about what they already know about the rules and what new information they will find.[来源:学#科#网]
Checking Yourself on Page 68 in the Workbook aims at encouraging students to make a self－assessment after they finish learning this unit.It is very important to improve their learning.Of course，a testing assessment is also needed.
In this period，the teacher can also provide more practice to consolidate what students have learned in this unit.

Suggested answers：
Write down what you have learned about global warming：
(Students' answers may vary.)The temperature of the earth rose about one degree Fahrenheit during the 20th century.It is human activity that has caused this global warming.All scientists subscribe to the view that the increase in the earth's temperature is due to the burning of fossil fuels.Some byproducts of this process are called greenhouse gases，which trap heat and warm the earth.Without the greenhouse effect，the earth would be cooler than it is.But scientists don't agree with each other on the effects of global warming.Some think it will be a disaster，but some others think it's a good thing and we can do nothing to prevent the trend.By reading the second passage，we also know some easy and effective measures we can take to deal with global warming.
