于是查了朗文
base1 base1W1S1/be?s/v [T usually passive] to have your main place of work, business etc in a particular place The paper had intended to base itself in London. be based in sth The new organization will be based in Dallas. base on/upon [base sth on/upon sth] phr v to use something as the thing from which something else is developed Their relationship was based upon mutual respect. an economy based on farming On what do you base your theory?
[总结] 可见一般是 人 做base 的主语 物是宾语 而且多用被动语态 sb base sth. on sth. sth. is based on sth.
然后我又看到 OG-40 target 也是分不清主动被动

(A) seeming unlimited number of antibodies, each specifically targeted at (B) seeming unlimited number of antibodies, each targeted specifically to (C) seeming unlimited number of antibodies, all specifically targeted at (D) seemingly unlimited number of antibodies, all of them targeted specifically to (E) seemingly unlimited number of antibodies, each targeted specifically at (E 独立主格)
纠结于E为什么用 targeted 而不是 targeting? 然后又查了朗文 target2 target2v[T] to make something have an effect on a particular limited group or area The advertisement was designed to target a mass audience. target sth on/at sb/sth a new benefit targeted on low-income families The programme is targeted at improving the health of women of all ages. to aim something at a target target sth on/at sb/sth The missiles are targeted at several key military sites. to choose a particular person or place to do something to, especially to attack them or criticize them It's clear that smaller, more vulnerable banks have been targeted. He was targeted by terrorists for a second time last night.
[总结] 虽然朗文没有说是多用被动 但是可以看出target 和base 类似 也是 target sth on/at sth/sb de 或者 sth is targeted on/at sth/sb. 的表达
看到OG-79 似乎attribute 也是这样的词 The correct idiom in the active voice is someone attributes x (an effect) to y (a cause). In the passive voice, x (the effect) is attributed to y (the cause).
be estimated to be/have/cost etc The tree is estimated to be at least 700 years old. estimate something at something Organizers estimated the crowd at 50,000. 或前面已经有了一个确指的名词 level estimated at 3 amount estimated at 4
