Perfect Tenses: Summary and Quiz

Written by Leny Ortega

In the previous posts, I have summarized the simple tenses. In this post, we summarize the perfect tenses. Review exercises are provided below to assess your mastery of the lesson.

Perfect tenses have three types: Present perfect, Past perfect and future perfect.

The present perfect tense denotes actions that began in the past and continues up to the present time. It is also used to suggest events that happened at unspecific time before now. Has (singular) and have (plural) + past participle of the given verb are used to form the present perfect tense.

The past perfect tense of the verb is formed with Had (for singular and plural noun)+ past participle of the verb. This tense of the verb is used to express an action that happened before another past action occurred. Always remember that the second past action must use the simple past tense of the verb.

Similarly, for the future perfect tense two actions/events are required here. But, these actions are intended to be completed in the future. Expressions such as by tomorrow, by next year, ten years from now, etc. are commonly used plus the future perfect tense (will have + past participle). This is to suggest that the action is completed before a certain time.

Practice Quiz

1.) Ebola virus (has, have) spread in countries like Africa.

2.) The reinforcement team (arrived, had arrived) after the forty-four Special Action force members (has died, had died) in the encounter.

3.) The country (will have experienced, will experience) drought before the summer comes next year.

5.) The government of China (expressed, has expressed) its desire to end the territorial row with the Philippines.

6) Melinda (will have become, had become) a lawyer before her mother retires.

Simple Tenses: Summary and Quiz

Written by Leny Ortega
Previously, we have discussed simple and compound tenses. To recapitulate, simple tenses consist of present tense, past tense and future tense. The simple present tense is formed using the base form of the verb such as talk, walk, etc. (for plural noun or pronoun) or the s-form of the verb (talks, walks, etc) for singular noun or pronoun. Other forms of the verbs like the “be” verb such as is/ are; auxiliary verbs like has / have, do / does can be used. These forms of the verb are used to express actions that are habitually done, to state a fact or general truth.
The past tense is formed with the following verbs like was (singular) / were (plural), had and did (both for singular and plural). For regular verbs you just add –ed (talked, walked, etc) or a change in spelling is needed for irregular verbs (eat = ate, write =wrote, etc). This tense of the verb is used for actions that happened or completed in a definite past time. Time expressions like yesterday, last month, few days ago, etc. are used.
For actions that are intended to be completed or done in a particular time in the future, Future tense of the verb is used. Here, expressions like tomorrow, next year, next summer, etc. will signify futurity. Though, will /shall + base form of the verb can be used most of the time will + base form of the verb is preferred by most people both in oral / written communication.
To evaluate mastery of these simple tenses, exercises below are designed for this purpose.
Choose the appropriate verb in the following sentences. Check your answers below.
  1. Citizens in a democratic country (has, have) to select a leader through election process.
  2. Pump prices (go, goes) up rapidly depending on the scarcity of supply.
