Adjectives and Adverbs

Perfect Tenses
The perfect tenses tend to be quite difficult for students to master, especially because often they will not occur in the students’ mother tongue. Another problem is that often a perfect tense can be replaced by another tense in English; both of these, for example, are acceptable:
After we finished the meeting we all went home.
After we had finished the meeting we all went home.
As a TEFL‏‎ teacher you can explain how to form the perfect tenses fairly simply, but it is the usage where you will likely find most problems. Here it is a matter of offering your class plenty of examples and extensive practice in selecting which tense is the most appropriate to use. Ideally, of course, you would have the students learn how to use the tenses without explicitly teaching them or even identifying them. It does not take much for students to learn a basic construction such as:
Have you ever…
Of course, a great resource are timelines‏‎ and it will pay off to use these in class to give your students a visual representation of when perfect tenses are appropriate.
Health
Health is very important for every person. Everybody wants to be healthy and active. But in spite of that a lot of people nowadays have different illnesses and other health problems. I take care of my health because I like to feel well. But sometimes it seems that everyone all around me is ill, so it’s very easy to get sick. Sometimes I’m tired or stressed and I have a headache. So I have to use an aspirin or some other pain killer.
I don’t like to go to the doctor, but sometimes I have to. I go to the dentist once a year, because it’s important to look after your teeth. I hate toothache and can’t understand people who are ready to tolerate it because they are scared to go to the dentist.
In my opinion people should try to keep fit, eat healthy food and do some sports. But even if you do all that, it doesn’t guarantee that you won’t have some serious disease like asthma or cancer. The reason of it is a high level of pollution of the environment.
