should+动词原形
should
Practice

My classmate asks me how to ___________. My suggestion is that __________________.
Applying the rules
B3 Write a short paragraph based on each of the situations below, using predictive clauses.
Example
I’d like to join you in doing the project on the First World War, but my concern is that I don’t have much knowledge of it.
1 Tom is so nervous about his history test tomorrow.
2 David’s new book on world history has sold 10,000 copies!
Tom is going to have a history test tomorrow. The problem is that he gets stressed very easily whenever he takes a test. One way to stay relaxed is to keep calm and breathe deeply. Tom hopes it will help to solve his problem.
Sample
David’s new book has become a bestseller. At first, his concern was whether anyone would read his book. Actually, it is a well-written book that is also fun to read. The reason why his book has sold so many copies is that David’s love for history is represented in the way he writes about the topic.
