As you climb into the hill country, the roads get dustier and rougher, and fewer cars can be seen. Phonxay is one of the poorest districts of Laos, and many of its villages are only accessible by footpath. Our destination this hot morning is a concrete water tank that can be found just off the road. A UK organization helped to build it six years ago, and in the nearby village of Thapho, where clean drinking water is scarce, it has made a big difference. The tank feeds six taps which in turn give water to over 800 people---it has improved things for almost every family, from schoolchildren to grannies.

But lately, we were told, the clean water supply has come under pressure from new arrivals, people who have come down from the hill areas, and there are concerns that there will not be enough clean water to go round.

There are also serious worries about resources in Laos. The Chinese are building a 400km railway link, which could transform the landlocked country. About 150,000 Chinese workers will be involved. What will this do to local clean water supplies? How will the workers be fed?

The vast majority of Laotians live on farms. But with foreign investors wanting to buy up land, local people will have to be moved to make room for them. Heavily dependent on both foreign aid and foreign investment, Laos still falls well behind its neighbours, although its economy has grown at about 6% a year in the last decade. Its biggest economic problem is the lack of locally trained skilled workforce.

But there are reasons to be hopeful for the future. Laos is beautiful, and foreign tourism continues to grow: fortunately so far the fast-food chains and coffee bars common elsewhere are nowhere to be seen. Although all local media are government-run, the Internet is not controlled and the BBC and CNN are available to those with satellite dishes.

The government has also achieved impressive results in rural development, with communities benefiting not just from cleaner water but the construction of new schools and regular visits from medical teams. Poverty will not be history in Laos within the next decade, but with small steps forward and a bit of outside help, the country could find itself out of the UN’s least-developed category by 2020.

1.What is putting pressure on the local supply of clean water?

A. Dust from the road is making the water dirtier.

B. There are too many taps accessing the water.

C. The population of the area is growing fast.

D. The coming summer will dry up rivers and lakes.

2.According to the passage, which of the following is NOT a reason for Laos to be hopeful?

A. There are no fast-food restaurants in the country.

B. Laos has a variety of tourist attractions.

C. Information on the Internet is freely accessible.

D. The government owns all local media.

3.What is the most serious limitation on Laos’ economic growth?

A. The lack of local skilled workers.

B. A poor transportation system.

C. Too much foreign aid.

D. Too many foreign workers.

4.What is the best title for the passage?

A. Laos: slow-developing nations

B. Laos: small steps forward

C. Laos: least-developed land

D. Laos: landlocked country

US President Barack Obama made his first visit to China early this week, during which he sent out signals to China that the US sees China as its partner, not a rival.

During his Asian tour, Obama emphasized that the US isn't looking to contain the rise of a strong, prosperous China.

“China-US relations are very important. Maintaining such ties is the responsibility of both sides,” President Hu jintao told reporters after his meeting with Obama. Hu described the meeting as candid(坦诚的), constructive and fruitful, a “very good” talk.

The two leaders agreed that the key to China-US relations was to respect each other's interests and major concerns, but that national differences were normal.

A joint statement released after the meeting said it covered major issues, from nuclear proliferation to global warming to financial crisis and trade protectionism. “China-US relations go beyond any single issue,” said Obama.

China holds a large amount of US government debt – over $800 billion (5.5 trillion yuan) in Treasury bonds. Just before Obama's China visit, The New York Times described it as a trip to “pay his respects to his banker”.

The US is the China's biggest export market, accounting for more than 70 percent of China's exports. Total trade between the two was worth $400 billion (2.7 trillion yuan), in 2008.

In addition to the financial interdependence, there are educational exchanges to be considered. More than 11,000 Americans studied in China last year, for a 25 percent increase over the previous year, according to the Institute of International Education in the US. Meanwhile, Chinese students are the second largest group of foreign students in the US, and their numbers are on the rise. Last year, 81,000 mainland students went to the US, a 20 percent increase from 2008. According to the joint statement issued on Tuesday, for the next four years, over 100,000 American students will be sent to the China for study.

Still, people in the two countries may have a long way to go in improving their opinions.

49.What’s the text mainly about?

A The significance of Obama’s visit to China

B The effects of Obama on China –US relations.

C How the two leaders solve the political and financial problems between each other.

D The educational exchanges between the two countries.

50. What does the underlined sentence in the second paragraph mean?

A The US is looking forward to becoming as prosperous as China.

B Obama believes China is the most prosperous country in Asia.

C Obama’s government sees China as its partner,not a rival.

D Obama emphasized China would be more prosperous than the US in the future.

51.How many major issues did the meeting cover according to a joint statement?

A Three B Four C Five D Six

52. We can infer from the text_____________

A China is the largest debtor of US government in terms of treasury bonds

B Obama expressed his strong wish to visit China again

C Chinese students are the largest group of foreign students in America since 2008

D Although the two countries have made progress in cooperation ,national differences still exist.

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.

1.The best title of this passage probably is _______.

A．The importance of clone

B．First insects are cloned

C．The disagreement in clone

D．The advantages of clone

2.The scientists cloned flies because________.

A．there are fewer and fewer flies in the world

B．flies are easy to find and cheap to use

C．they can gain some experience before cloning other animals

D．it is safe to clone flies

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

C．this time scientists cloned flies successfully and easily

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