13填空
I'm bored. Let's ______ ______ with our friends at the town centre.（和朋友闲逛）
✅ 正确答案：hang out
解析：hang out with friends = 和朋友闲逛/聚会。hang out 是非正式用语，表示"消磨时间、闲逛"。注意 hang 的过去式是 hung（悬挂义）或 hanged（绞死义），不要混淆。完整短语：hang out with sb（和某人一起闲逛）。
14填空
She spends all her ______ ______ on clothes and games.（零花钱）
✅ 正确答案：pocket money
解析：pocket money = 零花钱（父母定期给孩子的少量钱）。pocket = 口袋，money = 钱。这是一个不可数名词短语，不能说 pocket moneys。例句：My parents give me £10 pocket money every week.
15填空
I'm really ______ ______ eating at the cafeteria every day.（厌倦做某事）
✅ 正确答案：tired of
解析：be tired of doing sth = 厌倦做某事。注意搭配：tired of + doing/名词（厌倦……），区别于 tired from + doing（因……而疲劳）。例：I'm tired of studying.（我厌倦学习了）vs I'm tired from studying.（我学习学累了）。本题语境是"厌倦每天在食堂吃饭"，用 tired of。
16填空

✅ 正确答案：give ... a try
解析：give sth a try = 尝试一下某事。固定搭配：give + 事物 + a try。也可以说 have a try / have a go。例：I've never eaten sushi before, but I'll give it a try.（我以前从没吃过寿司，但我要试一试。）注意不要写成 give a try sth ❌。

✅ 正确答案：recommend ... to
解析：recommend sth to sb = 向某人推荐某物。recommend /ˌrekəˈmend/ 注意拼写和重音。搭配结构：recommend + 事物 + to + 人。❌ recommend sb sth（不能双宾语）。✅ I recommend this book to you. 也可以接 that 从句：I recommend that you try this restaurant.
⚡ 三、语法专项题（10题）
19单选
If I ______ you, I'd join the youth club.
A. am
B. was
C. were
D. be
✅ 正确答案：C. were
解析：If I were you 是虚拟语气的固定搭配，表示"如果我是你"（与现实相反的假设）。无论主语是什么人称，if 从句中一律用 were，不用 was/am/is。这是 PET 高频考点。 ❌ If I was you → ✅ If I were you ❌ If I am you → ✅ If I were you 记忆口诀：虚拟语气 if 句，were 通吃所有人称。
20单选
If I were you, I ______ worry about the test.
A. won't
B. wouldn't
C. don't
D. didn't
✅ 正确答案：B. wouldn't
解析：If I were you 句型的主句必须用 would/wouldn't + 动词原形。不能用 will/won't（那是真实条件句），也不能用 don't/didn't。 ✅ If I were you, I wouldn't worry. ❌ If I were you, I won't worry. ❌ If I were you, I don't worry. 缩写：would not = wouldn't；I would = I'd。
21改错
找出错误并改正：If I were you, I'd to study harder.
✅ 正确答案：去掉 to → If I were you, I'd study harder.
解析：would（I'd）后面直接加动词原形，不能加 to。这是最常见的语法错误之一。 ❌ I'd to study → ✅ I'd study ❌ I would to go → ✅ I would go ❌ I wouldn't to eat → ✅ I wouldn't eat 记忆：would 是情态动词，和 can/must/should 一样，后面直接跟动词原形。
22改错
找出错误并改正：If I was you, I would choose the bowling alley.
✅ 正确答案：was → were：If I were you, I would choose the bowling alley.
解析：虚拟语气中 if 从句固定用 were，不用 was。即使主语是 I/he/she/it，也用 were。 ❌ If I was you → ✅ If I were you ❌ If he was you → ✅ If he were you 这是 PET 写作和口语中的高频扣分点，务必记住。
23改错
找出错误并改正：If I were you, I will go to the sports centre.
✅ 正确答案：will → would：If I were you, I would go to the sports centre.
解析：If I were you 是虚拟语气（与现在事实相反），主句必须用 would，不能用 will。will 用于真实条件句（可能发生的情况），would 用于虚拟条件句（不可能/假设的情况）。 真实条件句：If it rains, I will stay home.（可能下雨） 虚拟条件句：If I were you, I would stay home.（我不可能是你）
24填空
If I ______ you, I ______ (not / give up) so easily.
✅ 正确答案：were; wouldn't give up
解析：完整句子：If I were you, I wouldn't give up so easily. if 从句用 were（虚拟语气固定用法），主句用 wouldn't + 动词原形（否定建议）。give up = 放弃。翻译：如果我是你，我不会这么轻易放弃。
25填空
If I ______ you, I ______ (think of) the climbing centre for the party.
✅ 正确答案：were; would think of
解析：完整句子：If I were you, I would think of the climbing centre for the party. think of = 考虑/想到。注意这里也可以用 I'd think of（缩写形式）。翻译：如果我是你，我会考虑把派对安排在攀岩中心。

A. am; will
B. was; would
C. were; would
D. were; will
✅ 正确答案：C. were; would
解析：虚拟语气固定搭配：If I were you, I would + 动词原形。A 用了 am/will（真实条件句，不适用）；B 用了 was（虚拟语气不用 was）；D 用了 were 配 will（主句应该用 would）。只有 C 完全正确。这是 PET 考试中最高频的语法选择题型。
27单选

B. If I were you, I'd to go to the gym.

✅ 正确答案：C
解析：逐项分析： A ❌ was → 虚拟语气应用 were B ❌ I'd to go → would 后不加 to C ✅ were + I'd go → 完全正确 D ❌ will → 主句应用 would 这道题综合考查了 If I were you 句型的三个易错点，是 PET 典型考题。

💬 四、情景理解题（6题）
29阅读
Read the dialogue and answer: A: How about the new Italian restaurant?
B: If I were you, I would avoid that place. It's too expensive.
What does B think about the restaurant?
A. It's a great place.
B. It's not worth going to because of the price.
C. He hasn't been there.
D. He wants to go there.
✅ 正确答案：B
解析：B 说 "I would avoid that place"（我会避开那个地方）+ "It's too expensive"（太贵了），说明 B 认为这家餐厅不值得去，原因是价格太高。avoid = 避免/避开。这里 If I were you, I would avoid... 是用虚拟语气给出否定建议的典型用法。

D. They don't like trying new things.
✅ 正确答案：B
解析："I'd rather we give it a try" = 我更愿意我们试一试。"If we never try new things, we will never find our favourite places" = 如果我们从不尝试新事物，就永远找不到最喜欢的地方。核心意思是：尝试新地方很重要，这样才能发现喜欢的地方。I'd rather = 宁愿/更愿意。

✅ 正确答案：C. regret or disappointment
解析："That's a real shame" = 太可惜了/真遗憾。shame 在这里不是"羞耻"的意思，而是"令人遗憾的事"。real 加强语气。同义表达：That's too bad. / What a pity. / That's unfortunate. 这是 PET 口语中表示同情/遗憾的高频表达。

A. The cafeteria is closed.

D. The park is too far.
✅ 正确答案：B
解析：A 说 "I'm really tired of eating at the cafeteria" = 我真的厌倦了在食堂吃饭。be tired of = 厌倦/腻了，说明 A 是因为一直在同一个地方吃饭感到无聊，想换个地方。不是因为食堂关门（A）、不喜欢意大利菜（C）或公园太远（D）。

38改写
Rewrite using "If I were you":
"You should try the new skatepark near the park."
✅ 正确答案：
If I were you, I'd try the new skatepark near the park.
解析："You should..." 是直接给建议的表达，改为 If I were you 句型时：should + 动词原形 → I'd + 同一动词原形。注意 should 和 would 的区别：should 是"应该"（直接建议），would 是"会"（假设性建议，更委婉礼貌）。
39改写
Rewrite using "If I were you":
"Don't waste your money on that expensive restaurant."
✅ 正确答案：
If I were you, I wouldn't waste my money on that expensive restaurant.
解析：否定祈使句 "Don't + 动词" 改为 If I were you 句型时：Don't waste → I wouldn't waste。注意人称变化：your money → my money（因为主语从 you 变成了 I）。waste money on sth = 在某事上浪费钱。
