It’s now been over two decades since scientists in Scotland successfully cloned a sheep and named the newborn Dolly. In the years since, the technology that powers cloning 【小题1】 (advance) slowly but steadily.

Recently, scientists in China have cloned two bouncing baby monkeys, theoretically 【小题2】   (open) the door for the cloning of humans. 【小题3】   , the researchers stress that they have no intention of cloning humans. They think that the general public and the government will not allow the extension of 【小题4】 (apply) of these methods from non-human primates to humans. Instead, the ultimate goal is to create cloned monkeys that can be used to test new treatments for diseases 【小题5】 (associate) with human genes. The research is greatly 【小题6】 (benefit) to the medical development.

The monkeys, both female, are named Zhong Zhong and Hua Hua, from the word “Zhonghua”, 【小题7】 meaning is “Chinese nation”. They were produced 【小题8】 (effective) using some of cloning techniques that created Dolly 22 years ago. The researchers plan to continue improving the technique 【小题9】 (call) somatic cell nuclear transfer to increase the efficiency of cloning. The same technique has been used to clone 23 different mammal 【小题10】 (species) so far, including sheep, mice, cattle, pigs, cats and dogs.

Antarctic scientists were left【小题1】(astonish) when they discovered a unique creature at the bottom of the ocean, a documentary showed. The icy continent is【小题2】great interest to scientists as it is a totally unspoiled landscape 【小题3】they can study the history of the Earth and the effects of climate change. Thousands of scientists stay there, 【小题4】(dig) below the ice to get a better idea of the icy continent's past.

The team of scientists started a journey through the surrounding waters of Antarctica 【小题5】(discover) some of the most unusual oceanic life known to man. Thankfully, cameras were around to catch one of the most strange moments, when leading scientist Andrew Stewart made an interesting discover about Snailfish (狮子鱼). Snailfish are【小题6】 (poor) understood and Andrew may have found a new species. The sea【小题7】 (have) a wide variety of fish to thrill biologists.

“There may be about 115 species of the snailfish there,” Andrew said, “this is【小题8】 I came to Antarctica, seeing things like this. It’s just beyond 【小题9】(word). We now have the whole families of fish that are found nowhere else in the world except in the Southern Ocean. These are【小题10】(attract) animals.”

It has the ability to reduce pain and relax people both mentally 【小题6】 physically. 【小题7】(work) in green environment, people have fewer stomachaches. Red can make people 【小题8】(increase) appetite. Many decorators will include different shades of red in the restaurant. And many commercial websites will have a red “Buy Now” button because red is a color that 【小题9】(definite) catches a person’s eye. Unlike red, blue is believed to cause people to lose appetite. Therefore, if you want to eat 【小题10】(little) than before, eating from blue plates can help.
