Now the story

A new blood test can identify more than 50 types of cancer.

Not only that, in 85% of cases, it correctly located the source of the disease.

The test works by looking for changes in the genetic code of cancers.

Researchers at Oxford University, where the trial took place, say results have been encouraging so far, but there's more to do.

You ve been looking at the headlines?

Beth, what's the vocabulary we have?

Show Promise, miracle and World 1st.

This is news review from BBC Learning English.

Let's look at our 1st headline.

This is from BBC News. Multi cancer blood test shows real promise in an HR study.

So the headline says that This blood test shows promise, and that's the expression we're looking at.

It contains the word promise, which you probably know it means to say that you're going to do something.

But together with show is it different?

It is quite different. Yep. So with show, it's a two word expression, and it means that something is on the way to being successful.

So the headline is saying that This blood test shows promise.

It's on the way to being successful.

It could be successful. Yes, that's right.

A note that in the headline, it says, shows real promise.

This makes the success seem stronger.

It's a very common combination. We can also say shows a lot of promise.

Can you give us some other examples now?

Yes. Well, you can use show promise quite widely.

E.g. I heard you practicing your Spanish earlier, beth.

And it really shows promise much as graphies.

And I heard you practicing your singing.

Your singing is is showing promise.

Yeah, okay, so don't worry, I'm not going to sing.

Let's look at that again. Let's look at our next headline.

This is from The Economic Times India.

US company comes up with miracle blood test that can detect 50 types of cancer.

Okay, this headline, again, is about this new blood test that can detect cancer.

The word we're looking at is miracle.

Now, beth, I thought a miracle was connected to religious things, like walking on water or making something dead come back to life.

Well, it can be that, yeah, but we can also use it more widely.

So a miracle is a very big achievement, and often something quite unusual.

So, e.g. maybe your team is losing really badly at half time, but then they bring it back and they win.

It's a miracle, yes? And we can use miracle as an adjective, as in the headline, and it's used to describe something which is incredible.

So a miracle blood test. That's right.

Another example would be a miracle baby.

If someone is trying really hard to get pregnant and then they achieve it.

Let's look at that again. Let's look at our next headline.

This is from the Express Major Cancer Breakthrough, as world's 1st blood test can detect 50 types of disease.

So the headline says, this blood test is a major or breakthrough, or breakthrough is a very important discovery or event.

But we are looking at World 1ST.

It describes the blood test as World 1st, and again, too familiar words, world and 1st.

But when we put them together, and what does it mean?

Well, together, world 1st means very important, because it's the 1st in the world, and it's also used to show incredible new achievements, like this blood test.

CA Yeah. So other examples in the world of DNA, the cloning of Dolly the Sheep was a worldfirst, and also the astronauts landing on the moon in 1969.

It's a World 1ST. Yes, and take notes.

We can put World 1ST before or after the noun, e.g.

we can say,

a World 1ST blood test, or we can say, this blood test is a World 1ST.

Let's

look at that again. We ve had show, promise, show signs of future success.

Miracle describes something incredible, and world 1ST

very important,

because it's never been done before.
