Language Links combines grammar, vocabulary and phrases to give the range of language you need to communicate effectively in English. To talk about clothes, for example, you not only need vocabulary (trousers, skirt), but also grammar (I'm wearing, she's wearing) and phrases such as get dressed. Special links between units direct you to related language areas, allowing you to choose your own learning path through the book and progress at your own pace.
I hope you find it useful to review what you have learnt during this school year.
