It might  get  broken. Peter  got  hurt in a crash. If we want to show the person or thing doing the action we use  by : She was attacked  by  a dangerous dog. The money was stolen  by  her husband.

ADJECTIVES AND ADVERBS

Imagen
Adjectives and Adverbs Definitions An  adjective  is a word or set of words that  modifies  (i.e., describes) a noun or pronoun. Adjectives may come before the word they modify. Examples: That is a  cute  puppy. She likes a  high school  senior. Adjectives may also follow the word they modify: Examples: That puppy looks  cute. The technology is  state-of-the-art. An  adverb  is a word or set of words that modifies verbs, adjectives, or other adverbs. Adverbs answer  how ,  when ,  where ,  why , or  to what extent — how often  or  how much  (e.g.,  daily ,  completely ). Examples: He speaks  slowly  (tells  how ) He speaks  very  slowly  (the adverb  very  tells  how  slowly) She arrived  today  (tells  when ) She will arrive  in an hour  (this adverb phrase tells  when ) Let's go  outside  (tells  where ) We looked  in the basement  (this adverb phrase tells  where ) Bernie left  to avoid trouble  (this adverb phrase tells  why ) Jorge works out  strenu

INDIRECT QUESTIONS

Imagen
Indirect questions If we do not begin a question directly, but begin it with something like:  Can you tell me…? Do you know…? I wonder if…?  The word order is the same as in an affirmative statement. Direct question: What  is he  doing? Indirect question: Do you know what  he is  doing? Direct question: Where  have they  been? Indirect question: I wonder where  they have  been? If the direct question contains the auxiliary DO, we omit it in the indirect question. Direct question: What  do you  want? Indirect question: Can you tell me what  you  want? Direct question: When  did she  leave? Indirect question: Do you know when  she  left? In yes/no questions,  if  or  whether  is used. The word order is the same as in  reported questions . Direct question:  Have you  seen my dog? Indirect question: Could you tell me  if you have seen  my dog?

PRESENT PERFECT SIMPLE

PRESENT PERFECT DEFINITION OF THE PRESENT PERFECT TENSE The present perfect is used to indicate a link between the present and the past.

An action performed during a period that has not yet finished.  She  has been  to the cinema twice this week  (= and the week isn't over yet.) A repeated action in an unspecified period between the past and now.  We  have visited  Portugal several times.
