What may bring animals back from extinction by using their DNA?

Cloning technology.

Have scientists made mammoth walk the earth once again?

No. If scientists can find undamaged DNA in the mammoth, it may once again walk the earth.

Does the substitute mother’s species have to beexactly the same as the cloned animal?

No, but the substitute mother’s species must be similar to the cloned animal.

Reading

Sharing a planet with humans isn’t easy. It certainly hasn't been easy for the thousands of animals that, because of us, will soon die out.

Sharing a planet with humans isn't easy.→ It isn’t an easy thing to live with mankind on earth.because of : by reason of, on account of, as a result of

Scientists estimate that 40,000 different kinds of animals will become extinct this year, just as many will disappear next year, and the next.

Scientists estimate that 40,000 different kinds of animals will become extinctthis year. → It is scientists’ guess that up to 40,000 various species of animals will die out this year.

Many of Earth’s animals will soon become nothing more than old bones.

nothing more than = nothing but; merely  只不過是 old bones : dry/bleached bones; death

Many of Earth’s animals will soon become nothing more than old bones.→ Before long, many animals on earth will die out/be extinct.

Or will they?

Or will they? → Will they really become extinct soon?or 後接修飾語或更正語,表示對上一句話有所保留,或是對上一句話再加以補充 .He hit three home runs in the game-or did he?

Scientists say they have founda way to bring animals back from extinction.

bring...back = restore 使…恢復原先狀態A change of air has brought him back to health.Scientists say they have found a way to bring animals back from extinction.→ Scientists claim that they have discovered a way of making extinct animals alive again.

Using the animals’ DNA, scientists are learning to clone extinct animals.

乃現在分詞構句,因主詞與主要子句主詞相同 , 所以省略 .

Using the animal's DNA,scientists are learning to clone extinct animals.→ Scientists are trying to reproduce extinct animals by using their DNA.

This cloning technology couldsave many animals like the panda and the mountain gorilla.

could 表可能性He could be telling lies. → It could be that he is telling lies.Couldn’t you have left your wallet in theclassroom?This cloning technology could save many animals like the panda and the mountain gorilla.→ It is possible that scientific skill of cloning will save such animals as the panda and the mountain gorilla from extinction.

Scientists plan to collect the DNA of these endangered animals. If oneday they do become extinct, the stored DNA can be used to bring these animals back.

one day = some day (未來的)某天I will come to visit my friends in America one day.do 用來加強語氣She did write to say thank you.sth + be used to + V (某物)被用來…Watches are used to tell the time.sb + be used to + N/V-ing  習慣於…My father is used to taking a walk after dinner.

Scientists plan to collect the DNA of these endangered animals. If oneday they do become extinct, the stored DNA can be used to bring these animals back.

If one day they do become extinct, the stored DNA can be used to bring these animals back.→ Suppose these animals really die out some day, scientists can use the DNA they keep to bring them back from extinction.

In fact, this is already happening right now.

in fact = in truth/effect; actually; as a matter of fact  事實上We thought he was poor, but in fact, he was the richest one here.

In fact, this is already happening right now.→Actually, scientists are now using the stored DNA to restore the extinct animals.

Scientists are cloning an Indian oxthat became extinct in 2000.Someday, this technology may be used to clone animals that have been dead for thousands of years.

Someday, this technology may be used to clone animals that have been dead for thousands of years. → Sometime in the future, scientists may use this skill to produce animals that have disappeared for a long long time.

Take the mammoth for example.take...for example = take/cite...as an example  以…為例Large cities are often troubled by pollution. Take,for example, the air pollution.

This animal has been extinct for 10,000 years. But in 1999, a perfectly preserved mammoth was discovered.

But in 1999, a perfectly preserved mammoth was discovered.→ But it was only in 1999 that scientists found a well-kept mammoth.

Scientists hope to find undamaged DNA in the animal. If they can findit, the mammoth may once again walk the earth. 

undamaged = complete; whole  完整的Scientists hope to find undamaged DNA in the animal.→ It is hoped that the well&-kept DNA of the mammoth can be found.If they can find it, the mammoth may once again walk the earth.→ If the DNA can be found, the mammoth may appear again on earth.

This scenario sounds like something from the movie JurassicPark.

This scenario sounds like something from the movie Jurassic Park.→ All this seems to be a part/plot of the movie Jurassic Park.

Then, what about T. rex? What/Howabout...?用來「詢問消息或徵求意見」I've finished my homework. What aboutyou?What about his chance of winning the game?

Then, what about T. rex? → Then, what will happen to T. rex?

Will it one day come back to life,too? That's not very likely. Dinosaurs have been extinct for too long.

That’s not very likely. → It’s impossible

Finding the complete DNA of a dinosaur would be nearly impossible.

would 表推測It would be about a mile from here to town.I think this would be cheap at 100 dollars.

Finding the complete DNA of a dinosaur would be nearly impossible.→ It seems almost impossible to find undamaged DNA of a dinosaur.

Scientists also face challenges in cloning more recently extinct animals.

in = regarding; concerning; as to   在…方面;關於John's behind others in reading, but a long way ahead in math.

Scientists also face challenges in cloning more recently extinct animals.→Scientists also have some difficulties when they clone animals that have recently become extinct.

For one, a clone must have a substitute mother.

substitute mother 表「代理孕母」,又為 surrogate mother 。For one, a clone must have a substitute mother.→ One of the challenges is that a cloned animal needs a substitute mother to grow inside.

The young animal does not have togrow inside an animal of its ownspecies, but the mother’s species must be similar to that of the cloned animal.

be similar to = resemble  和…相似The earth is similar to an orange in shape.the mother's species must be similar to that of the cloned animal.→ the substitute and the cloned animal should be alike in species

An ox, for example, could have a cow for a mother, but definitely not a monkey.

An ox, for example, could have a cow for a mother, but definitely not a monkey. → For instance, a cow can be the substitute mother to an ox, but undoubtedly a monkey can't.
