As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治疗的) stem cells.

In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(细胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.

Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.

3.The failure of most cloned animals is due to _______.

A．the difference of other animals’ genes

B．the improper technique of clone

C．the complex of other animals

D．the improper rearrange of the adult gene

4.It can be inferred from the last paragraph that ______.

A．the clone of insects before used grown-up cells

B．the clone of insects were never experimented before

D．based on this success, other animals will be cloned in large quantities.

The number of Japanese students in the Chinese mainland is more than those studying in the US, according to Japan’s Ministry of Education, Culture, Sports, Science and Technology, a Taiwan news outlet reported on Monday.

Japan saw the peak of studying abroad in 2010 when 124,000 sought academic careers overseas.About 61,000 Japanese studied in the US in 2010, about half the total studying abroad.But since then, the number has decreased.In 2015, the number was down to only just over 20,000, about 20 percent of Japanese students being educated overseas.

The number of Japanese going to the Chinese mainland to study has been rising since 2009 and now surpasses the US.

An official spokesman said, “Choices are various for studying abroad nowadays, not just limited to the US. Many Japanese universities have an increasing number of exchange pro-grams with Chinese universities and Japanese companies now tend to prefer people with academic experience in Asia rather than the US or Europe as previously.Tuition fees (学费) are another reason.Annual fees in US universities are almost twice those charged by Chinese universities.”

Some Japanese experts say the decline indicates young Japanese are satisfied with the domestic situation rather than preparing for challenges outside.

1.How many Japanese students studied abroad in 2015?

A. About 61,000. B. About 100,000.

C. About 124,000. D. About 200,000.

2.What does the fourth paragraph mainly talk about?

A. The tuition fees about studying in the US.

B. The choices for Japanese students to study abroad.

C. The reasons why Japanese students go to study in China.

D. The problems that Japanese students have when studying in China.

3.The underlined word “domestic” in the last paragraph is closest in meaning to “____”.

A. native B. previous

C. complex D. simple
