   Grammar
   Present perfect

   💡Remember!
     We use the present perfect (have/has+past participle) to talk about:
     - something that happened in the past, but is still true or important now.
       Example: I have lost my key. Now I can't open the door.
     - something that started in the past, and is still happening now (often used with since or for).
       Example: They have lived here for a year. 
     - something that was completed in the very recent past (often used with just or recently).
       Example: He has just finished his homework.

Circle the correct answers.

   1. They just found / have just found a suitable solution to the problem.
   2. Since people invented / have invented the first computer, they create / have created many more interesting inventions.
   3. The woman is very angry because her son lost / has lost his smartphone.

   Gerunds and to-infinitives

   💡Remember!
     We use gerunds (verb + -ing):
     - after verbs such as avoid, enjoy, and finish.
       Example: I enjoy cooking.
     - as subjects of sentences.
       Example: Learning English is fun.
     We use to-infinitives (to + verb):
     - after verbs such as want, decide, and allow.
       Example: My parents don't allow me to use a smartphone.
     - after adjectives to give opinions, starting It's...
       Example: It's fun to learn English.
     - as subjects of sentences.
       Example: To learn English is fun.
     Note: Some verbs, such as like, love, and hate can be followed by either gerunds or to-infinitives.
     Example: I like playing/to play computer games.

Complete the sentences using the gerund or the to-infinitive of the verbs in brackets. Sometimes both forms are possible.
