Read the text below and pay attention to the use of enough and too.
When you travel around the world, it is important to know enough information about the manners of different cultures.
To enjoy world travel fully, avoid too much planning all at once. Trying to do too many thing can be too tiring. Take your time. To really understand the culture of a country, try to visit enough places.
Stay in each place long enough to get to know the local traditions.
Many young people are excited to travel to other places, but you should wait until you are old enough to travel alone.
Read and summarise
Read the text and pay attention to the use of enough to and too ... to.
In many countries, people are patient enough to wait in line in banks and shops. Also, they are kind enough to hold the door for you when you go in or out of a building. In public places, people are polite enough to keep their voices down.
In many countries, people are too polite to jump the line in banks and shops. Also they are too kind to push past you when you are in their way. In public places, people are thoughtful enough to keep quiet.
We usually use enough to and too ... to like this:
be patient enough to wait in line
kind hold the door for you
polite keep their voices down
thoughtful keep quiet
be too polite to jump the line
kind push past you
In the structures above, we can add “for someone” before the to-infinitive.
e.g. The food is too hot for Robert to enjoy.
enough和enough to的用法
enough可以用在复数名词或不可数名词前，表示“足够的，充足的”；也可以用在形容词或副词后，表示“足够地，充足地”。
e.g. There is enough room for you. 有足够的地方给你。
This house isn't big enough for us. 这房子对我们来说不够大。
We didn't leave early enough. 我们离开得不够早。
我们可以用“be + adjective +enough+to do”的结构来描述一个人的品质和能力。
e.g. Confucius is wise enough to be one of the greatest ancient Chinese thinkers.
孔子十分睿智，是中国古代最伟大的思想家之一。
The girl is not brave enough to go near the dog.
这个女孩胆子不够大，不敢靠近那只狗。
Summary
too 和 too ... to 的用法
too 可用在形容词和副词前，表示“太，过于，过度”。
e.g. This bag is too heavy for me. 这个包对我而言太沉了。
我们可以用“be + too +adjective + to do”的结构来表达因某个原因而没有完成某个动作或达到某种状态。
e.g. He is too tired to go swimming. 他太累了，没法去游泳了,
The water is too hot to drink. 水太烫了，还不能喝。
too后面还可以加much和many，too much后面加不可数名词，too many后面跟复数名词。
e.g. We don't want to spend too much money. 我们不想花太多的钱。
There won't be too many people in the park. 公园里人不会多。
我们可以在动词不定式前加介词 for 引出逻辑主语。
e.g. The box is very heavy. The little boy cannot carry it.
盒子太重了，这个小男孩搬不动。
= The box is too heavy for the little boy to carry.
The apple is very high. The child cannot reach it.
苹果太高了，这个孩子够不着。
= The apple is too high for the child to reach.
enough to和too ... to两种结构有时可以转换，注意其中的形容词要作相应的变化，即：enough前的形容词与too之后的形容词互为反义词，同时应改为not… enough to的形式。
e.g. He is too young to look after himself.
= He is not old enough to look after himself.
他年龄太小不能照顾自己。
