Task 4. Grammar: Present Perfect vs Present Perfect Continuous
I have been looking (look) for low-fat products all morning, but I haven't found (not/find) any yet.
She has eaten (eat) too much junk food lately, so she has decided (decide) to start a diet.
Have you ever tried (try) cooking with exotic spices like cardamom?
They have been shopping (shop) for groceries for two hours, and their bags have gotten (get) heavier!
My mum has just made (just / make) a shopping list, so we can go to the supermarket now.
Explanation:
Present Perfect Continuous (have/has been + -ing) is used for actions that started in the past and are still continuing, or have recently stopped but have a present result (e.g., 'I have been looking...').
Present Perfect Simple (have/has + past participle) is used for completed actions, or actions with a result in the present (e.g., 'I haven't found...', 'She has decided...').
In sentence 4, 'have been shopping' emphasizes the duration of the activity, and 'have gotten' shows the result of that activity.
