Hello everyone,

Could you please tell me if I have used "will be able to" and "can" in the following sentences?

1. We will be able to see cars bring problems.

2. Engineers can offer a solution.

3. Scientists can find a cure for the disease in the future.

My opinion/ I think #1 is wrong and "can" should be used instead. #2 is fine because we don't know when "engineers" can offer a solution. #3 is wrong because "will be able to" should be used instead. Is my opinion right?

Regards,

Joseph

Joseph A1. We will be able to see cars bring problems.

You've got a weird sentence here.

We [can / will be able to] see that cars cause problems.

'can' is much better than 'will be able to'.

Joseph A2. Engineers can offer a solution.

Good. 'will be able to' is not wrong here, however, if the speaker thinks the solution will be farther in the future. 'can' gives the impression that the solution will be found sooner.

Joseph A3. Scientists can find a cure for the disease in the future.

There's an explicit mention of 'in the future', so I'd use 'will be able to', not 'can'.

Thanks a lot, CalifJim.

1. Why is "bring" wrong? It has been repeated twice on two different pages. Sunrise 11/student's book/page 14 and page 18. Here are the photos:

2. CalifJim, could you please tell me if it's okay to use "can" if the future is known even if it is too far? For example:

Scientists can/will be able to find a cure for the disease next year.

Scientists can find a cure for the disease in one century.

Scientists can/will be able to find a cure for the disease in 500 years.

And so on.

3. I edited my post and added this question, too. I am sorry. Is it okay to use "will be able to" with "now" as follows?

I will be able to lift this box now.

Joseph A1. Why is "bring" wrong?

It's not wrong. It's just not as precise as "cause". Anyway, that wasn't the main problem with the sentence.

The problem has more to do with omitting "that" after "see". It causes confusion between the following kinds of structures:

1) We can see people enjoy pizza.
2) We can see that people enjoy pizza.

1) We're are looking (or can look) at people as they enjoy pizza.
2) We understand from our previous observations that, in general, people like pizza.

1) has the use of 'see' as a catenative verb.
2) has the use of 'see' as a reporting verb.


So, bottom line, you don't want to give the impression that

We can see cars bring problems, i.e., that we are seeing the cars as they bring problems (to us).

But you do want to say that

We can see that cars bring problems, i.e., that we have observed that, in general, cars tend to have problems associated with them.

What about the other two questions #2 and #3? 😔Could you please answer them?

Students: We have free audio pronunciation exercises.
Joseph A could you please tell me if it's okay to use "can" if the future is known even if it is too far?

The question is somewhat contradictory. It's hard to know the future at all, and the farther into the future you look, the more difficult it is to know what will happen. But let's look at the examples and see what you've got.

Scientists can/will be able to find a cure for the disease next year.
Scientists can find a cure for the disease in one century.
Scientists can/will be able to find a cure for the disease in 500 years.

I would not use 'can' for any of those. And when it comes to curing a disease, I would add something like "hopefully" at the beginning of each of those sentences.

Hopefully, scientists will be able to find a cure for the disease next year.
I hope that scientists will be able to find a cure for the disease in one century.
Everyone is hoping that scientists will be able to find a cure for the disease in 500 years.

Now, if you want 'can', you should leave out the definite time phrases like 'next year', 'in 100 years', and so on. Then you can express the idea in terms of a thought or belief you have.

I [think/believe] that scientists can find a cure for the disease.
I [think/believe] that, in time, scientists can find a cure for the disease
.

('will be able to' is also OK here.)

Is it okay to use "will be able to" with "now" as follows?

I will be able to lift this box now.

In the right context, and with some minor adjustments, that could work. Take a look at the following dialog.

— I can't lift this box.
— That's because it's full of heavy tools. Take some of them out.
(I take some of the tools out of the box and set them aside.)
— OK. Now I'll be able to lift it.
(I try to lift it, and I succeed.)
— See? I told you I'd be able to lift it.

Please be patient. When you ask several questions in one post, sometimes it's better if I give separate answers. It takes time to think about the question and compose an answer.

You now have the answers to the other two questions.

CalifJim😔Could you please answer them?Please be patient.

Thank you so much, again.

I added that emoji because I thought it would be a bother to ask you some questions in one thread. I knew that I would take a lot of your time. That was my intention. Otherwise; I can wait until tomorrow.
