Over a period of very many years various international agreements have been drawn up to prohibit the use of chemical weapons in wartime, but they have hardly been effective, have they?

For many years now, chemical warfare has been banned by international agreement, but can the ban be enforced?

If various international bodies agreed to a long-term ban on chemical warfare, couldn’t the ban be put into effect?

How effective might the prohibition of chemical warfare be if it had the backing of so many international bodies?

Can such international bodies be relied upon to ban effectively and in the longterm the use of chemical weapons in time of war?

With a little more experience I’m sure he will develop into a highly efficient manager.

In my experience, men of his type rarely function well in positions of authority.

It’s a very demanding position and I’m not at all sure that he has the experience needed for it.

A job of that description requires someone with a great deal of experience.

It’s inevitable that one should ask oneself whether he really is the right man for the job.

In most cases, so long as a criminal avoids taking risks he is not likely to be suspected.

It seems that the majority of criminals start to take greater risks and so get arrested.

Once the average criminal has fallen under suspicion he can no longer trust his luck.

In my opinion, however hard he may try, no criminal can ever escape arrest.

Apparently, by trusting their luck just once too often, most criminals do eventually get arrested.

Initially she wasn’t at all keen, to stop working, but she now finds that looking after her children affords her much satisfaction.

Now when she spends her days at home with her children she feels more fulfilled than she ever did when she was out working.

Then she was unwilling to give up her job but now her sense of responsibility to her children tells her she must

She was enjoyed bringing up her children but nevertheless looks forward to resuming work.

When the children have grown up she may regret that she gave up her career for them.

His career began with a stunning success, but then he did nothing to earn either the praise or the approval he now receives.

In spite of his early promise, his career record shows nothing deserving of the special praise or glory he seems to expect.

His career record has not lived up to his early promise, so he really does not merit either our approval or our praise.

Had his career record been in line with the brillant start he made, he would most certainly have earned high honours and great renown.

He was amazingly successful at the start of his career but afterwards he has done nothing to merit even a moderate amount of approval and certainly not renown.

Can’t we defer our decision about withdrawing these goods from the market for a further six months?

Can we come to some agreement about which goods to take off the market during the next six months?

Would you agree to withdrawing these goods from the market after another six months?

Why can’t we wait six months before we withdraw these products from the market?

Didn’t we agree six months ago that these goods ought to be taken off the market?

You never can keep things secret for long, so the best is to tell him about it soon.

You can’t keep him in the dark about it for ever, and telling him will get harder the longer you wait.

Surely it’s better to let him know now than to wait until he finds out for himself.

He’ll have to be notified about it, and the sooner the better.

He’ll find out some time, and by putting it off you won’t make it easier for yourself.

I agreed to meet in order to discuss the matter thoroughly.

Had I realised what he wanted to talk to me about I would not have agreed to a meeting.

I never did understand why he wanted us to meet and discuss the matter

He talked about us meeting but never explained why

I realised there was something to be discussed but didn’t know exactly what.

Rescue-workers found two more victims after the search for them had lasted a week.

At the end of the week the two survivors joined in the search for the others.

They were only able to save two people though rescue work continued for a full week.

By the end of the first week there was little hope of finding the missing two.

Once those two were rescued at the end of the week, they abandoned the search for the others.

It follows that the harder he works the more likely the business is to be successful.

The success of the business will obviously depend upon the amount of hard work he puts into it.

Unless he’s willing to make more of an effort, the business is never likely to be a success.

No matter how hard he tries, it’s clear that he won’t ever turn that business into a going concern.

He’s a failure as a businessman even though he is extremely hard-working.
