This section is made up of two parts, prefixes and suffixes£¬ and organs of the body. Students will first learn the commonly used prefixes and suffixes which may help them work out the meanings of words that they do not know. Then students will look at two pictures to learn words and expressions related to organs of the body£¬ and read a small passage about how the body works. Students are expected to enlarge their vocabulary in this section and put the relevant words and expressions into practice.
