- If they are willing, we will join them.
- Unless he comes, I shall not leave.
- If it rains, we will not go.
357. Adverb clauses expressing purpose. These are introduced by such subordinate conjunctions as, that, in order that and lest. For example:
- Take good care that you understand this lesson.
- I will go today in order that I may meet him.
- Watch these carefully lest they be stolen.
- Read the labor press that you may know the truth.
Notice that that, when used in this way, as a pure conjunction, means in order that. For example, the sentence above might read:
- Read the labor press in order that you may know the truth.
