第1题
Shenhua Company Ltd (Shenhua) has been buying products from Kangyi Chemicals Company (Kangyi Chemicals) for more than one year. By the end of 2013, the two parties negotiated to settle the previous business transactions and confirmed that Shenhua owed an outstanding amount of RMB 800,000 yuan to Kangyi Chemicals.
Several days later, Shenhua entered into an agreement with its holding company, namely Shenhua Holdings, to transfer all its debts of RMB 800,000 yuan due. In doing so, Shenhua neither notified Kangyi Chemicals, nor got a consent from Kangyi Chemicals.
Having discovered this information, Kangyi Chemicals sent an email to Shenhua Holdings to inquire whether Shenhua’s debts had been transferred to Shenhua Holdings. Shenhua Holdings acknowledged the transfer but did not promise to settle the debts as a new debtor.
Kangyi Chemicals filed a lawsuit against Shenhua Holdings for the unsettled RMB 800,000 yuan. Shenhua Holdings submitted the following defences: First, the transfer agreement between Shenhua and Shenhua Holdings was an invalid one as Shenhua failed to get prior consent, as required by the law, from Kangyi Chemicals before the completion of transfer. Second, the goods delivered by Kangyi Chemicals in the last six months contained material defects which caused loss and damage to Shenhua as the original counterparty.
Required:
Answer the following questions in accordance with the Contract Law, and give your reasons for your answers:
(a) state whether the transfer agreement between Shenhua and Shenhua Holdings was a valid one; (6 marks)
(b) state whether Shenhua Holdings was entitled to submit its defence on the ground of the defects in the goods delivered by Kangyi Chemicals to Shenhua. (4 marks)

Night of the Living Ants
When an ant dies，other ants move the dead insect out of the nest．This behavior. is interesting to scientists，who wonder how ants know for sure-and so soon-that another ant is dead．
Dong-Hwan Choe，a scientist at the University of California，found that Argentine ants have a chemical on the outside of their bodies that signals to other ants，“I’m dead-take me away．”
But there's a twist to Choe's discovery．Choe says that the living ants-not just the dead ones -have this death chemical．In other words，while an ant crawls around，perhaps in a picnic or home，it's telling other ants that it's dead．
What keeps ants from hauling away the living dead？Choe found that Argentine ants have two additional chemicals on their bodies，and these tell nearby ants something like，“Wait-I'm not dead yet．” So Choe's research turned up two sets of chemical signals in ants：one says，“I'm dead，”the other set says，“I'm not dead yet．”
Other scientists have tried to figure out how ants know when another ant is dead．If an ant is knocked unconscious，other ants leave it alone until it wakes up．That means ants know that unmoving ants can still be alive．
Choe suspects that when an Argentine ant dies．the chemical that says“Wait-I'm not dead yet” quickly goes away．Once that chemical is gone，only the one that says“I'm dead”is left．“It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard(墓地)，not because its body releases new，unique chemicals after death，”said Choe．When other ants detect the“dead”chemical without the“not dead yet”chemical，they haul away the body．This was Choe's hypothesis(假设)．
To test his hypothesis，Choe and his team put different chemicals on Argentine ant pupae(蛹)． When the scientists used the“I'm dead”chemical，other ants quickly hauled the treated pupae away． When the scientists used the“Wait-I'm not dead yet”chemical，other ants left the treated pupae alone． Choe believes this behavior. shows that the“not dead yet”chemical overrides(优胜于)the“dead”chemical when picked up by adult ants．And that when an ant dies，the“not dead yet”chemical fades away． Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest．
The phrase“this death chemical”in paragraph 3 refers to
A．the chemical that contains poison．
B．the chemical that announces death．
C．the chemical that prevents death．
D．the chemical that causes death．

2 The risk committee at Southern Continents Company (SCC) met to discuss a report by its risk manager, Stephanie
Field. The report focused on a number of risks that applied to a chemicals factory recently acquired by SCC in another
country, Southland. She explained that the new risks related to the security of the factory in Southland in respect of
burglary, to the supply of one of the key raw materials that experienced fluctuations in world supply and also an
environmental risk. The environmental risk, Stephanie explained, was to do with the possibility of poisonous
emissions from the Southland factory.
The SCC chief executive, Choo Wang, who chaired the risk committee, said that the Southland factory was important
to him for two reasons. First, he said it was strategically important to the company. Second, it was important because
his own bonuses depended upon it. He said that because he had personally negotiated the purchase of the Southland
factory, the remunerations committee had included a performance bonus on his salary based on the success of the
Southland investment. He told Stephanie that a performance-related bonus was payable when and if the factory
achieved a certain level of output that Choo considered to be ambitious. ‘I don’t get any bonus at all until we reach
a high level of output from the factory,’ he said. ‘So I don’t care what the risks are, we will have to manage them.’
Stephanie explained that one of her main concerns arose because the employees at the factory in Southland were not
aware of the importance of risk management to SCC. She said that the former owner of the factory paid less attention
to risk issues and so the staff were not as aware of risk as Stephanie would like them to be. ‘I would like to get risk
awareness embedded in the culture at the Southland factory,’ she said.
Choo Wang said that he knew from Stephanie’s report what the risks were, but that he wanted somebody to explain
to him what strategies SCC could use to manage the risks.
Required:
(a) Describe four strategies that can be used to manage risk and identify, with reasons, an appropriate strategy
for each of the three risks mentioned in the case. (12 marks)

Rivers are one of our most important natural resources (资源). Many of the world&39;s great cities are located(坐落) on rivers, and almost every country has at least one river running through it that plays an important role in the lives of its people.
Since the beginning of the history, people have used rivers for transportation(运输). The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Gangs is great, but it is also important for transportation; Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation (航海), however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides transportation, rivers give food, water to drink, water for crops(庄稼), and chances for fun and entertainment for the people who live along their banks. In order to increase(增加) the supply of crops, engineers sometimes build a dam (大坝) across a river and let a lake from behind the dam. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals(化学物质) and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits (利益) of this natural resource.
The greatest river for navigation is ___________.
A.the Amazon
B.the Nile
C.the Mekong
D.the Mississippi
From a dam, people can use the water for ___________.A.keeping the rivers clean
B.only making electricity
C.washing clothes
D.irrigation and making electricity
The water in the river is polluted because of _____________.A.people's drinking water too much
B.people's swimming in the river too much
C.chemicals and other materials
D.people's building a dam across a river
The best title of the passage is ___________.A.Rivers in Cities
B.The importance of Rivers
C.Transportation
D.Natural Resources

A successful WTO round requires two big bargains to be struck: a transatlantic deal between America and the EU and a north-south deal between the rich and the poor. Yet at Seattle this year there is a long way to go before such broad bargains can be considered, let alone struck.
America wants a few priority issues to be settled. Its list includes an extension of the duty-free status of e-commerce, a broader IT pact, reform. of the WTO dispute settlements system, increased WTO transparency and the phase out of tariffs in eight sectors including chemicals, energy products and environmental products. The EU on the other hand professes to want a more comprehensive approach that focuses on removing tariff peaks for such imports as textiles, glass and footwear, but would preserve tariff preferences for developing countries.
The biggest obstacle may be the insistence of many developing countries that they will block further liberalization until their gripes over the Uruguay round are addressed They want their obligations in areas such as intellectual property, investor protection, subsidies and anti-dumping to be eased. They argue that the Uruguay round has failed to deliver expected benefits in such areas as agriculture and textiles.
Though by no means a monolithic block, the developing countries share a feeling that whatever the promise of liberalization at the WTO, rich countries will Conspire to keep their markets closed. Indeed, the EU insists that freeing trade should be "controlled, steered and managed according to the concerns of EU citizens". That is in keeping with a view, widespread on the continent, that "a protectionist trade policy is a price readily paid for political objectives".
However great these obstacles are, they could be overcome if America were still leading the drive for freer world trade. With its economy doing well, greater access to foreign markets seems a less pressing priority. The Clinton administration is unwilling to make politically painful concessions required to achieve that aim. So there is a possibility that the Seattle round will turn out to be a fiasco. If that happens, it will encourage the anti-WTO groups to go on the offensive. America, the EU and Japan would increasingly be tempted by managed trade.
The WTO's transparent and non-discriminatory rules require all member countries to ______.
A．exchange domestic markets for foreign markets
B．make concessions in foreign trade
C．adopt the most effective route to free trade
D．enforce trade policies even handedly
