This sentence does not flow smoothly. "various teaching methods should be taken..." No. Methods are not taken, they are implemented. You need to use the verb that fits your subject always in English. "achieve the goal of health education efficiency" To talk about achieving a goal is very very general. In English it is best to use specifics whenever possible; if you speak in overly general terms, no one will know what you are talking about, and will not pay attention to what you have to say, because you are wasting their time avoiding details. Let me re-write your sentence for you: "Gorden believes that, according to current characteristics of Health education, new teaching methods should be implemented to increase the curriculum's focus on the most up-to-date information, facts, and Doctor warnings."

It looks fine to me, but I'm wondering how you thought to condense it.

I think that it is a bit wordy. I think there are other ways you can reword it and it will have a similar effect. According to Gorden, the various teaching methods for health education should be taken to achieve efficiency. I have a few questions for your sentence. 1) What are the various teaching methods? 2)What are the characteristics? I ask this because it seems" the various teaching" are the same as "the characteristics". This reasoning allowed me to cut out the characteristics part from the sentence. I also think that it was wordy because you want people to understand. Gorden purposes the characteristics of health education's teaching methods should be taken to perform efficiently. I hope this helps. Let me know if it does or doesn't. ^^ zai jian
