This is the adverb form: it describes HOW something is done, namely in a way that gets a good result for the money spent. You attach it to a verb — 'produce it cost-effectively', 'deliver the service cost-effectively', 'heat the building cost-effectively'.

This這 is the adverb form是副詞形: it它 describes描述的是 HOW something is done一件事是「怎麼」做的, namely也就是 in a way用一種 for the money spent讓花下去的錢 that gets a good result換到好結果的方式。 You你 attach it to a verb把它接在動詞後面 — 'produce it cost-effectively'、'deliver the service cost-effectively'、'heat the building cost-effectively'。

The meaning is the same as 'cost-effective', with the same warning attached: it is not a synonym for 'cheaply'. Doing something cheaply just means spending little; doing it cost-effectively means the spending was well matched to what came out of it.

The meaning意思 as 'cost-effective' 跟 'cost-effective' is the same一樣, with the same warning attached連那句提醒也一樣: it它 is not不是 a synonym for 'cheaply' 'cheaply' 的同義詞。 Doing something cheaply cheaply 地做一件事 just means只是說 spending little花得少; doing it cost-effectively cost-effectively 地做 means意思是 the spending這筆花費 to what came out of it和做出來的成果 was well matched配得剛剛好。

It is a heavy, formal word that lives in reports, tenders, and management writing, and it usually sits at the end of a clause. In practice you will meet the adjective 'cost-effective' ten times for every one 'cost-effectively', and many careful writers rewrite the adverb away — 'in a cost-effective way' — because the four-syllable ending is a mouthful.

It它 is a heavy是個沉重, formal word正式的字, that lives in住在 reports報告, tenders標案, and management writing和管理文件裡, and it而它 usually通常 sits坐在 at the end of a clause子句的尾端。 In practice實際上, you你 every one 'cost-effectively' 每遇到一次 'cost-effectively', will meet the adjective 'cost-effective' ten times就會遇到十次形容詞 'cost-effective', and many careful writers而許多講究的寫作者 rewrite the adverb away會把這個副詞改寫掉 — 'in a cost-effective way' — because因為 the four-syllable ending那四個音節的字尾 is a mouthful實在拗口。
