答案解析：

1. high→highly。
2. relative→relatively。
3. easily→easy。在该句中easy紧跟在系动词be之后，与clear并列，即“your speech is clear and easy to follow”。
4. late→later。
5. high→height。“in height”表示“在高度上”的意思，为固定搭配，没有in high的表达法。
6. costlier→costly。costly是形容词，意思是昂贵的，它的比较级是more costly，costlier是错误形式。
7. necessary→necessarily。
8. medicine→medical。
9. worth前加are。本句有一个由“when”引导的时间状语从句，主句“Clearly some risks worth taking”缺少谓语动词，因为worth是形容词，一般于“be worth doing”。
10. minutes→minutes’。本句中minutes是名词，不能直接修饰后面的名词delay，应该用名词所有格形式。
