Presentation
I've studied in China for a year and now it's the Christmas holiday. I've been back in the UK for three days, but it feels like a century! It's amazing to see my family. Also, I really love Christmas and the delicious food. However, I've had some digital problems here.
Today, I wanted to get some vegetables and meat from a shop. I decided to ride a shared bike to get there. But it took forever to find a bike! I finally found an old one. But that 20-minute ride cost me an arm and a leg - 4.8 pounds!
In the shop, I quickly got everything I needed. I wanted to pay with my smartphone. I asked the shopkeeper to show the QR code, but she didn't understand! Next, I tried to use my digital wallet, but the shop's payment system didn’t work. The shopkeeper told me to use cash. As I always make digital payments in China, I never carry my wallet. I had to go home to get some cash.
When I got home,I was so tired that I gave up on cooking. I ordered my favourite dishes through an app instead,but the delivery was really slow. When my dishes finally arrived 90 minutes later, they were stone-cold! I had to heat them one by one in the oven. I felt tired and hungry.
Except for today, I’ve had a great holiday. However, I’m looking forward to going back to China. The technology there lets me live a more convenient life!
Now find more sentences with these structures in the reading passage.

动词不定式作宾语补足语
动词不定式作宾语补足语是英语中常见的语法现象，指的是用 “to + 动词原形” 的结构补充说明宾语的动作、状态或身份，使句子意义更完整。其基本结构为：主语 + 谓语动词 + 宾语 + 动词不定式（to do）。
Presentation
动词不定式作宾语补足语
一、常见可接不定式作宾补的动词分类
并非所有动词都能接不定式作宾补，以下是几类典型动词：
1. 表示 “命令、要求、允许” 的动词
这类动词后接不定式作宾补时，强调对宾语的指令或许可，常见动词有：ask, tell, order, allow 等。
例句：
My mother told me to clean the room. 妈妈叫我打扫房间。
The teacher allowed us to leave early. 老师允许我们早点离开。

2. 表示 “希望、期望、想要” 的动词
这类动词侧重表达主语对宾语的期望或意愿，常见动词有：want, wish, expect 等。
例句：
I want you to help me with my homework. 我想让你帮我辅导作业。
They expect the team to win the game. 他们期待这支队伍赢得比赛。
She wishes him to stay for dinner. 她希望他留下吃晚饭。

二、不定式作宾补的否定形式
不定式的否定形式是在 to 前加 not，即 “not to do”。
例句：
The doctor advised him not to drink too much.
医生建议他不要喝太多酒。
Parents told their kids not to play with fire.
父母告诉孩子们不要玩火。

三、it 作形式宾语时的宾补结构
当宾语是不定式短语时，常用 it 作形式宾语，将真正的宾语（动词不定式）放在宾补之后，结构为：主语 + 谓语 + it + 宾补 + 动词不定式。
例句：
I find it difficult to learn French. 我发现学法语很难。
（it 是形式宾语，to learn French 是真正宾语，difficult 是宾补）
She made it a rule to read for an hour every day.
她定下规矩，每天读书一小时。

四、需要注意的特殊情况
let, make, have这三个使役动词在主动句中接不带 to 的不定式作宾补，但被动语态中需加 to：
主动语态：The teacher made us study hard.
老师让我们努力学习。
被动语态：We were made to study hard by the teacher.
help后接不定式作宾补时，to 可带可不带：
He helped me (to) carry the box. 他帮我搬箱子。
