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.

The passive: be + past participle

- 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.

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?
难度 1/5 · 今日首次完成可获 100 金币及少量额外奖励
"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.

- 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.
