Think! An old newspaper can become something new. A glass bottle can be recycled and recreated. Even a small decision can help protect the environment. Look at the image and think about your own habits:
Do you try to reuse things instead of throwing them away?
Do you avoid buying products with unnecessary packaging?
What could encourage more people to recycle correctly?

Notice that each question uses a different structure after the first verb: "try to reuse"; "avoid buying"; "encourage people to recycle". Why do we use an infinitive after one verb, a gerund after another and an object followed by an infinitive after the third? You have already learnt the basic rules for using gerunds and infinitives in Form 7. Before exploring more challenging verb patterns, revise what you already know: What Makes a Good Role Model? Infinitive and Gerunds
 
Learn: three Verb Patterns to Remember
When two verbs appear together in a sentence, the form of the second verb depends on the first verb. Compare:
Many people avoid wasting water.
Our school plans to reduce plastic waste.
The campaign encourages students to reuse old materials.
The first verb guides you towards the correct grammatical pattern.
 
Pattern 1: Verb + Gerund
Some verbs are followed by a gerund: the -ing form of a verb: verb + -ing form
Many families avoid wasting water.
Experts recommend reusing glass containers.
Have you considered taking public transport more often?
Common verbs followed by a gerund: avoid, consider, dislike, enjoy, finish, imagine, keep, mind, practise, recommend, suggest

Note: "expect" can be used in two patterns.
1. You have already learnt that "expect" can be followed directly by an infinitive.
The company expects to introduce recyclable packaging soon. (The company expects something to happen, and the company will introduce the packaging.)
2. "Expect" + object + infinitive. Use this structure when another person or thing is expected to do something.

Special Pattern: make, let and help
Some verbs are followed by an object and the base form of a verb. Unlike the verbs in Pattern 3, "make" and "let" are not followed by "to".
Make + Object + Base Form — use when one person, situation or experience causes another person to do something.
Rising energy prices make people think more carefully about their consumption. (Rising energy prices cause people to think more carefully.)
The documentary made us realise how much plastic reaches the ocean. (The documentary caused us to realise something important.)
Let + Object + Base Form — use when someone allows another person to do something or when something makes an action possible.
Some cafés let customers refill their water bottles for free. (The cafés allow customers to refill their bottles.)
Reusable containers let people carry food without disposable packaging. (Reusable containers make it possible for people to carry food without unnecessary waste.)
After "help", you can use either the base form or the infinitive with to. Both structures are correct. Structures: help + object + base form / help + object + to + base form
Small changes can help families reduce waste.
Small changes can help families to reduce waste.
Both sentences have the same meaning.
 
Same Verb, Different Meaning
Some verbs can be followed by either a gerund or an infinitive. However, the two structures do not express the same idea.
stop + gerund — use when someone ends an activity and does not continue doing it.
Many people have stopped buying single-use plastic bags. (They no longer buy single-use plastic bags.)
stop + infinitive — use when someone pauses one activity in order to do something else.

try + gerund — use when someone tests a possible solution to see whether it works.
Try using a reusable bottle instead of buying bottled water. (Test this idea and see whether it works well for you.)
try + infinitive — use when someone makes an effort to do something, especially when it may be difficult.

remember + infinitive — use when someone does not forget an action that is necessary.

forget + gerund — when someone cannot remember whether they did something; with "never" to emphasise that an experience was especially memorable.

mean + gerund — use when something involves, requires or results in a particular action.

mean + infinitive — use when someone intends or plans to do something.

Some verbs are followed by a preposition. When another verb comes after the preposition, use a gerund.
Structure: verb + preposition + -ing form
The town succeeded in reducing household waste.
Many families are thinking about installing solar panels.
Common Verb Combinations: apologise for, complain about, concentrate on, insist on, succeed in, think about, talk about
Svarīgi!
Be careful with "to" — the word "to" is not always part of an infinitive. In some expressions, "to" is a preposition. When "to" is a preposition, it must be followed by a gerund.
look forward to + gerund
We look forward to taking part in the clean-up.
be used to + gerund
Many families are used to sorting their rubbish.
 
Compare
We want to recycle more carefully. ("to recycle" is an infinitive.)
