Longer sentences, same rules
- Harder Language Form and Meaning texts join ideas into longer sentences: The robot that we built won a prize. The prize was given by the mayor. If we win again, we'll get a trophy.
- Three patterns cover many of those boxes: relative clauses, the passive and conditionals.
Relative clauses: who, which, that, whose, where
- who for people, which for things, that for both (in clauses without commas), whose for "belonging to", where for places.
- The girl who sits next to me… · The book which I borrowed… · The boy whose bike was stolen… · The town where I was born…
- Mr Lee is the teacher ___ class won the quiz. who / which / whose / where
- The class belongs to the teacher: whose.
Mr Lee is the teacher ___ class won the quiz.

Choose the relative word by what it refers to.
The passive: be + past participle
- Use the passive 被动语态 when the action matters more than who did it: The school was built in 1998. Lunch is served at noon.
- Form = be in the right tense + past participle 过去分词: is cleaned, was opened, will be sent, has been finished.
- The letters were send yesterday ✗ → were sent ✓. The passive always needs the past participle.

ความยาก 1/5 · 100 เหรียญ + บอนัสน้อยๆ เมื่อทำสำเร็จครั้งแรกในวันนี้
Passive present = are + past participle "cleaned".
Active or passive?
- Ask: does the subject do the action, or receive it? The students painted the wall (they did it). The wall was painted (it received the action).

Conditionals: if + result
- Zero: facts. If you heat ice, it melts. (present + present)
- First: real future. If it rains tomorrow, we will stay inside. (present + will). Never will after if here.
- If it ~~will rain~~ rains, we will stay inside. The if part uses the present.

Second conditional: imagined situations

- With be, test texts often use were: If I were taller, I would play basketball.

Match each sentence to its conditional type.
ความยาก 2/5 · 140 เหรียญ + บอนัสน้อยๆ เมื่อทำสำเร็จครั้งแรกในวันนี้

Common mistakes
- Using which for a person: the man which… ✗ → the man who.
- Forgetting be in the passive: The bridge built in 1900 ✗ (as a full sentence) → The bridge was built.
- Mixing conditionals: If I have time, I would help ✗ → If I had time, I would help or If I have time, I will help.
Which sentence is correct?
ความยาก 1/5 · 100 เหรียญ + บอนัสน้อยๆ เมื่อทำสำเร็จครั้งแรกในวันนี้
"Which" cannot refer to a person; the bridge sentence needs "was"; "have … would" mixes two conditionals.
Read to the end of the sentence
- The clue is often after the box: The cake ___ by my brother → by shows passive. If I ___ a million dollars + would → had.
- Read the full sentence before you choose. It costs five seconds and saves the question.
In "The cake ___ by my brother", what tells you the box needs a passive verb?
ความยาก 1/5 · 100 เหรียญ + บอนัสน้อยๆ เมื่อทำสำเร็จครั้งแรกในวันนี้
The clue is after the box; reading to the end shows it.
Make a correct sentence.
ความยาก 3/5 · 200 เหรียญ + บอนัสน้อยๆ เมื่อทำสำเร็จครั้งแรกในวันนี้
"Which was opened in 1990" describes the museum; the main verb is "is".
Recap
- who / which / that / whose / where by what they point to.
- Passive = be + past participle; check who does the action.
- if + present → will; if + past → would; zero conditional for facts.
Write three sentences about your school: one with "who" or "where", one passive sentence, and one first conditional.
Writing the patterns yourself makes the test boxes faster to spot.
