Indirect SpeechWhen a declarative sentence is changed from direct into indirect speech, it becomes an object clause introduced by the conjunction that which is often omitted. Personal and possessive pronouns are shifted or remain unchanged according to the sense. The most common verbs in both direct and indirect speech are say, tell and ask. He said (that )/ told me (that) he didn’t have much time. She asked me if/whether I wanted anything. · If the reporting verb denotes a past action, tenses of the verb of the direct speech are changed according to the rules of the sequence of tenses.
· It is often necessary to make time and place changes in relation to tense changes. Examples of possible changes:
· When instructions, commands, requests and invitations are changed into indirect speech, the Imperative Mood is replaced by the infinitive. Indirect commands, requests, etc. are normally expressed by tell, order, ask, beg, advise, remind, warn, etc. with a person addressed and the infinitive.
· In indirect Yes/No questions there is no inversion, the subject comes before the verb, the same as in the statement. Because of the statement word order do, does, or did are not used to form indirect questions. If and whether are interchangeable after ask, want to know, wonder, etc. but whether conveys slightly greater doubt. Whether is always preferable when there are alternatives.
Some verbs, like discuss can only be followed by whether. If or whether must always be used when reporting Yes/No questions and cannot be omitted (unlike that in reported statements).
· In indirect wh- questions the subject also comes before the verb as in the statements, and do, does, or did are not used.
Modal verbs The verbs can, may, must, ought, shall, should, will, would, need and dare form a special class of verbs which are called modal verbs. They are used with the infinitive of another verb. They denote neither actions nor states; they show that the action or state denoted by the infinitive is considered as possible, obligatory, necessary, desirable. probable, doubtful, allowed, advisable, etc.
Modal verbs have certain peculiarities: 1. they have no infinitive, no gerund and no participles; accordingly they have no future tense, no continuous and perfect tenses.
2. they (except ought and partly need and dare) are followed by the infinitive without the particle to.
3. they have no ending - (e)s in the third person singular of the present tense.
4. In the interrogative form modal verbs are placed before the subject. In the negative form the particle not is used after the modal verb.
