Check the following sentences for confusing shifts in tense. If the tense of each underlined verb expresses the time relationship accurately, write S (satisfactory). If a shift in tense is not appropriate, write U (unsatisfactory) and make necessary changes. In most cases with an inappropriate shift, there is more than one way to correct the inconsistency. Reading the sentences aloud will help you recognize differences in time.
