Hi Ben,
My birthday is next Saturday! I'm having a picnic in the park near my house at eleven o'clock. My cousins are coming from Taichung too. Could you bring your guitar? Everyone loves your songs. Let me know if you can come!
Love,
Amy

解析會說明每個選項為什麼對、為什麼錯——這是課堂上老師做的事，我們把它放上來。分數只記在你自己的瀏覽器裡，不會上傳。
開放填空沒有僥倖：會就是會，不會就是不會
開放填空是 KET 閱讀卷最容易失分的大題：沒有選項可以猜，拼錯就是錯。孩子錯的格子，會精準指出文法哪一課還沒站穩——是介系詞不熟？be 動詞常漏掉？還是助動詞用錯位？找到破口，才補得準。
