Dear native English speakers,

Would someone please proofread my sentences using the passive voice?

(b) English must be spoken in this class.

(c) Mt. Fuji cannot be seen from here.

(d) The fish cannot be seen in this lake.

(e) Bikes must be used in the area.

(f) The game will be played here tomorrow.

(g) The work has just been finished.

(h) The tree has already been cut down.

(i) This old machine has been used for many years.

(j) Those people have been discriminated for centuries.

(k) Rice has been eaten since ancient times.

Thanks in advance.

Everything looks pretty good to me. I think the only things I might need to know would be context to see if you mean what I think you mean. In sentence d do you mean that the fish that cannot be seen is in the lake that is mentioned but you just cannot see it, or that the fish is in a different lake? As in, you can't see the fish in this lake because it is in a different one. And in sentence e is it more important that the bikes must be used or that they are used in the area? For example, Bikes must be used in this area. Might imply that you can't use any other means of transporation in the area mentioned. While, Bikes must be used in this area. Might imply that area is a designated spot where you can use a bike. Sentence i is alright if you mean that the machine is still in use, if you want to say it is no longer in use but was you would replace has been with was. And in j I would add against after discriminated, that may be personal preference because I know what the sentence mean it just seems more natural to me with against there. Other than context though I can't find anything wrong with your sentences.

I agree, (j) should be "discriminated against".

Thank you for the help, OoTmaster and eeky. I appreciate it.

The sentences have no context because they are only for explaining
grammatical structures to my students.

How about these?
(1) There are many kinds of fishes in this lake, but this kind cannot be seen in the lake.
(2) No fish(es) can be seen in this lake because of the acid rain.
(3) You cannot use a car. Bikes must be used in this area.

The plural of fish is fish. But those sentences do give more context. If you are worried just about content all of your sentences are fine. And I didn't even think of adding additional information, that being said you have the right idea when it comes to the passive voice.

I would change 1 to read ....There are many kinds of fish in this lake , but this type can't be found.
I would change 2 to read.....No fish can be found in this lake because of/due to the acid rain.

The changes just sound more natural to me. Also on (1) if possible , I would put in the type of fish such as trout or carp ......
, but trout can not be found. (3) sounds OK to my ear.
