Application
Complete the passage with the help of word formation.
When you open a dictionary, you often come across a lot of unfamiliar words. You might think this is a bit scary. But many of them are formed using other simpler words. This is called word formation.
Words formed by combining other words are called compounds, for example, ____________ (a friend that you contact by writing, traditionally using a pen) and _____________ (known by many people).
Prefixes and suffixes often have fixed meanings. If you add un- or in- to a word, the new word usually means the opposite. For example, if something isn’t correct it’s __________, and if someone isn’t happy they are _________. Words with the suffixes -ment and -ness are often nouns. For example, if somebody has improved a lot, they have made great ________________.
penfriend
well-known
incorrect
unhappy
improvement

Some nouns and adjectives can be used as verbs, or the other way round. When we calm somebody down, they become ______. And we can give someone a present by__________ it.
And sometimes a word is made up of the first letters of several words: “World Trade Organization ” can be referred to as _____ , and _______ is short for “as soon as possible”.
It is impossible to know the meaning of every word, but knowing about word formation can help us guess their meanings.
calm
presenting

Today, American English is in common international use. It is different from British English in several ways, mostly in spelling and vocabulary. Some American spellings were created by Noah Webster, who made one of America's first dictionaries. He changed “-re” spellings to “er”, which is why 1_______ is spelt 2________ in American English.
The Americans and the British also use different words for everyday things. For example, Americans talk about putting 3____ in their cars and driving along the 4________ whereas in the UK, people put 5______ in their cars and drive along the 6__________.
Now Complete the passage with the words above. (P24)
subway/underground highway/motorway theater/theatre gas/petrol apartment/flat elevator/lift
theatre
theater
gas
highway
petrol
motorway
in ... ways
Americans take the7________ to the top floor of a building, but the British use the 8_____. In the US, they take the 9_______, but in the UK, people travel on the 10____________. Americans live in a(n) 11__________, while the British live in a(n) 12_____.
It's not as confusing as it seems: usually people from the two countries can understand each other from the context. But that doesn't stop them having a friendly argument about which word is the “right” one!

□ Learning to learn
Some of the language used on the Internet is different to the language used in other forms of communication. It may be a quick and, to you, clear way to communicate, but before you use it, stop and think: who do you want to communicate with and why Make sure that any abbreviations（缩写） and emojis（表情符号） you use are appropriate for the situation, and consider whether your readers will even know what you mean by BRB or COZ.
