Editor's Notes

  • #7 Sense verbs such as hear, smell, taste etc and feelings such as wish, hate, love, like, dislike, doubt, imagine, believe, know, prefer, realize, remember, understand, suppose, regret are not used in the present continuous. Possession verbs such as have and belong are not used in the present continuous. Stative verbs such as wish, hate, love, like, dislike, doubt, imagine, believe, know, prefer, realize, remember, understand, suppose, regret are not used in the present continuous. Communication verbs such as agree, disagree, deny, promise, mean, surprise, satisfy, impress are also not used in the present continuous.
  • #9 I have spoken, he has broken They have taken, he has shaken You have lost, it has cost Wind has blown, they have known Ram has been, Sam has seen We have given, the Sun has risen
  • #10 I have spoken, he has broken They have taken, he has shaken You have lost, it has cost Wind has blown, they have known Ram has been, Sam has seen We have given, the Sun has risen The first error using the wrong preposition. When using the present perfect to state where you have visited before using the verb ‘to be,’ many students use the preposition ‘in’ instead of ‘to.’ Where have you been? Another common error is using the present simple instead of the present perfect when talking about actions that started in the past and continue in the present. Time expressions are important with the present perfect as mistakes are made when the wrong time expressions are used. Note that specific time expressions in the past can’t be used with the present perfect.
  • #11 I have spoken, he has broken They have taken, he has shaken You have lost, it has cost Wind has blown, they have known Ram has been, Sam has seen We have given, the Sun has risen The first error using the wrong preposition. When using the present perfect to state where you have visited before using the verb ‘to be,’ many students use the preposition ‘in’ instead of ‘to.’ Where have you been? Another common error is using the present simple instead of the present perfect when talking about actions that started in the past and continue in the present. Time expressions are important with the present perfect as mistakes are made when the wrong time expressions are used. Note that specific time expressions in the past can’t be used with the present perfect.
  • #12 The past perfect is not used simply to say that something happened sometime ago. This meaning is conveyed by using the simple past. Sometimes, the error lies in using the simple past instead of the past perfect or the past continuous instead of the past perfect continuous. The past perfect denotes an action completed at some point in the past before some other past action commenced. When two actions in the past have to be referred to, the past perfect should be used for the earlier action, and the simple past for the later one.
  • #15 Incorrect: See that you will not do any damage. Correct: See that you do not do any damage. It is wrong to use the future tense in the subordinate clause when the verb in the main clause is in the imperative mood. If we’re talking about not having experienced something that we might experience in the future, we normally use the present perfect. I’ve never seen a movie in Spanish. I’ve never eaten broccoli. The present perfect is a present tense. It can’t be used with adverbs of past time. The present perfect tense cannot be used with adverbs that refer to a definite point of time in the past. If you want to say when something happened in the past, you have to use the simple past tense. The past perfect tense is not used to say that something happened some time ago. That idea is expressed using the simple past tense. The past perfect tense is only used to suggest that an action had completed before another action commenced.

  • #19 I really enjoyed to be being there yesterday. After certain verbs, we use the gerund instead of the infinitive. Enjoy is one of these verbs. Some other verbs that are followed by the gerund are consider, delay, dislike, finish, imagine, mind, miss, practice, risk, and tolerate. Waking up early was hard at first, but now I’m used to do doing it. We use to be + used to + gerund to talk about something we are accustomed to doing.
  • #21 After expressions like Do you know…, Could you tell me,.. and I was wondering if… we do not invert the subject and the verb. These are called indirect questions.
  • #22 In English, when a sentence discusses a past event, the sentence only needs one word to show that the event is in the past. The sentence “I went home,” for example, only includes one past-tense verb: “went” is the past tense of the verb “go.” But if you ask the speaker, “Did you go home?” the past tense leaps from the verb “go” to the auxiliary verb “do.” Using two past-tense markers instead of one is a common mistake in tense formation, as in the question, “Did you went home?” Here, both “go” and “do” are in past tense, but only “do” should be.
  • #23 Incorrect: He will help if you will ask him. Correct: He will help if you ask him. When the verb in the main clause is in the future tense, the verb in the subordinate clause should be in the present and not in the future.
  • #24 To talk about a hypothetical past, we can use would/might/could + have + participle. We do not use should to talk about a hypothetical past. We use should to criticize past actions or express regret.
