Use the Zero Conditional to talk about things that are generally or always true — scientific facts, rules, and predictable outcomes. If condition A happens, result B always happens.
Structure: If + Present Simple, Present Simple
Use the First Conditional to talk about a specific situation in the future and its likely result. It is a real possibility.
Structure: If + Present Simple, will/won't + base verb
Two very common words that work inside conditional sentences are when and unless. They each have a specific meaning and follow the same tense rules as if.
In an Active sentence, the subject does the action. In a Passive sentence, the subject receives the action.
When do we use the passive?
The manager (subject/doer)
writes (verb)
the report. (object/receiver)
The report (new subject)
is written (be + past participle)
(by the manager). (optional doer)
Here is how the Passive Voice looks in the most common English tenses. Notice how only the verb BE changes — the past participle (V3) always stays the same!
| Tense | Passive Structure | Active Example | Passive Example |
|---|---|---|---|
| Present Simple Routines, facts |
am/is/are + V3 | They clean the office every day. | The office is cleaned every day. |
| Past Simple Completed actions |
was/were + V3 | Shakespeare wrote Hamlet. | Hamlet was written by Shakespeare. |
| Present Continuous Happening right now |
am/is/are being + V3 | They are repairing my car now. | My car is being repaired now. |
| Present Perfect Recent past / experience |
has/have been + V3 | Someone has stolen my laptop! | My laptop has been stolen! |
| Past Continuous Was in progress in the past |
was/were being + V3 | Workers were building the road. | The road was being built. |
| Future Simple Future actions |
will be + V3 | The boss will evaluate the staff. | The staff will be evaluated. |
| Modals can, must, should |
modal + be + V3 | Employees must follow the rules. | The rules must be followed. |
These two prepositions are very common in English, especially in the Passive Voice. Students often confuse them — but they have different jobs!
Welcome to the team! As the department manager, I oversee daily operations. It is my responsibility to ensure that all tasks are carried out efficiently. Let me explain a few basic rules. First, if you arrive after 9:00 AM, you must sign the late register. This is a strict rule: if an employee is late three times in a month, they receive a formal warning. Second, we are all accountable for our workspace. If you finish your shift, you must tidy your desk. Unless the office is kept clean, we will have to hire extra cleaning staff, which costs the company money. Finally, if you need time off, you will need to submit a form. If the form is approved by HR, you will receive an email confirmation within 24 hours. We expect everyone to comply with these guidelines.
1. What happens if an employee is late three times?
2. What is the consequence if the office is NOT kept clean?
3. According to the text, what is the manager's main responsibility?
Have you ever wondered how your smartphone is manufactured? The process is highly complex and involves several stages, all of which must be supervised closely. First, the internal components are designed by engineers in the USA. However, the physical parts are usually produced in large factories in Asia. Once the parts are manufactured, they are shipped to an assembly line. At the assembly line, the phones are put together by both robots and human workers. Right now, a new model is being developed, and extra staff have been hired to deal with the workload. After assembly, every phone is evaluated for quality. The software is installed, and the battery is tested. Finally, the smartphones are packaged into boxes and sent to stores worldwide. If a defect is found during testing, the phone is sent back for repairs.
1. Where are the internal components designed?
2. What is currently happening regarding a new model?
3. What happens to a phone after the assembly stage?
