This seems a quite simple sentence. But I am confused about the phrase "take great effort".
Does it mean 'workers' make great effort and 'labors' benefit from their effort or mean something else. Does 'take great effort' is the same as 'make great effort'?
Thank you in advance!
Hi Jack,

The original sentence seems to be a little wrong. It should read:

'Labor on farms takes great effort by workers.'

'Labor on farms' = farm work, the types of agricultural tasks.
'Takes' = requires, demands
'Great effort' = a lot or work.

'Take effort' therefore means 'require a lot of work', whereas 'make an effort' means 'try'.

To rephrase the sentence meaning: 'Workers must work hard to do farm jobs'.

Hi, Mister, please go to this link where I found the original sentence. I am not sure the original is wrong or right itself. I thought "labor" in this sentence means "worker",that is why I found it is difficult to be understood. If it means "work", it will be easily understood.
Thank you so much for this.
Jack, that URL just takes me to a long index. Could you direct me more specifically?

sorry for that. Click on lessons 16-20 then you will find this sentence in lesson 17.

Got it, Jack. In Lesson 17, sentence (3) is wrong, and (2) is wrong also:

'2. Children always require great X energies from parents.' SHOULD BE 'ENERGY'

'3. X Labors on farms take great effort by workers.' SHOULD BE 'LABOR. . . TAKES'.

Looking through some of the other lessons, there are many sentences that are incorrect or unnatural. The site is probably maintained by non-native speakers, and I suggest that you abandon it, because it appears to be highly unreliable.
