Read the passage carefully and do the exercise below .
Different language learners learn words in different ways. Some learners make a list and put into it the meanings. Of new words in their mother tongue, and try to learn them by heart. However, others do not. Instead, they write one or two example sentences with each new word in order to remember how to use the word in the right way.
In order to remember words better, some learners even write each word and its use on a small piece of paper and stick it somewhere in their house so as to learn it any time.
Many language learners do not try to learn all new words they come across. They usually underline or highlight only the words they want to learn. This helps them remember important words.
Learners do not only learn the meanings of new words but also how to spell and pronounce them so as to use them in both writing and speaking.
There are also different ways of learning the same number of words. For example, if you try to learn ten words in two days, you can do so in two ways. You can learn the fist five words the first day, and then learn the other five the next day. However, because revision is necessary, you can learn all the ten words the first day and revise them the next day. This helps you practice the words more times.
Language learners should try different ways of learning words so as to find out the best way for themselves. Ask yourself the question: How should I learn words?
Use these suggested words to make questions then answer them:
Why / some learners / write example sentences / new words?
What / some learners / do / to remember words better?
What / language learners / do / remember important words?
Why / learners / learn / spell and pronounce words?

Air pollution is a serious problem in many cities. Motor vehicles, factories and other sources create so much air pollution that it may hang in the air like dirty fog. Air pollution threatens the health of the people who live in cities. City wastes cause water pollution when they are poured into the waterways. These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have difficulties in disposing of their garbage. The amount of garbage grows each year, but places to put it are quickly filling up. Citizens, governments, industries, scientists, and business people must work together in different ways to gradually reduce pollution. For example, most cities have introduced recycling programmes.
Motor vehicles and factories are among some sources of air pollution.
Air pollution doesn’t endanger people’s health in some cities.
Air pollution is the only problem of the environment mentioned in this passage.
Garbage disposal is a problem in many large cities.
Everyone must cooperate to reduce pollution.
We can reduce pollution by recycling programmes only.
