a time phrase for each of the specified tenses.
• Ask students to read the time phrases 1–8. Then tell
them to read the article again in order to find and
underline the verbs that are used with each of the time
phrases. Let students compare answers and identify
tenses in pairs before checking with the class.
• Ask students to match the time phrases with the tenses
in the grammar box. Note that there is sometimes more
than one possibility (the less common possibility is
shown in brackets in the answer key below).
