Present Perfect никогда не употребляется с такими обозначениями моментов как yesterday, last week, an hour ago, at five o'clock и т.п. С ними употребляется Past Simple.
В вопросах, начинающихся с when, всегда употребляется Past Simple, а не Present Perfect, поскольку вопрос задается о моменте или периоде времени.
Утверждения в Present Simple строятся очень просто:
I work for a big company. – Я работаю на большую компанию.
You watch TV every night. – Ты смотришь ТВ каждый вечер.
We like chicken wings. – Мы любим куринные крылышки.
They smoke a lot. – Они много курят.
1. We are looking forward to our granny coming.

5. Look at this beautiful scenery!
6. If you don't know the word, look it up in a dictionary.
