The Olympic Games originated in 776 B.C. in Olympia, a small town in Greece. Participants in the first Olympiad are said to have run a 200-yard race, but as the Games were held every four years, they expanded in scope. Only Greek amateurs were allowed to participate in this festival in honor of the god Zeus. The event became a religious, patriotic, and athletic occasion where winners were honored with wreaths and special privileges. They were banned in 394 A.D. by Emperor Theodosius, after they became professional circuses and carnivals.
The modern Olympic Games began in Athens in 1896 as a result of the initiative of Baron Pierre de Coubertin, a French educator whose desire was to promote international understanding through athletics. Nine nations participated in the first Games; over 100 nations currently compete.
The taint of politics and racial controversy, however, has impinged upon the Olympic Games in our epoch. In 1936 Hitler, whose country hosted the Games, affronted Jesse Owens, a black American runner, by refusing to congratulate Owens for the feat of having won four gold medals. In the 1972 Munich Games, the world was appalled by the deplorable murder of eleven Israeli athletes by Arab terrorists, The next Olympic Games in Montreal were boycotted by African nations; in addition, Taiwan Province withdrew. In 1980, following the former Soviet invasion of Afghanistan, sixty-two nations caused great dismay to their athletes by refusing to participate in the Games. The consensus among those nations was that their refusal would admonish the Soviets.
According to the passage, the first Olympic games were held ().
A.as a religious festival
B.for political reasons
C.as an international competition
D.as a professional athletes' competition

Thierry Daniel Henry (born on 17 August 1977) is a French football striker currently playing for Spanish La Liga club FC Barcelona and the French national team.
Henry was born and brought up in the tough neighborhood of Les Ulis, Essonne—a suburb of Paris—where he played for an array of local sides as a youngster and showed great promise as a goal-scorer. He was spotted by AS Monaco in 1990 and signed instantly, making his professional debut in 1994. Good form. led to an international call-up in 1998, after which he signed for the Italian defending champions Juventus. He had a disappointing season playing on the wing, before joining Arsenal (兵工厂) for 10.5 million in 1999.
It was at Arsenal that Henry made his name as a world-class footballer. Despite initially struggling in the Premiership, he emerged as Arsenal's top goal-scorer for almost every season of his tenure there. Under long-time mentor and coach Arsène Wenger, Henry became a prolific striker and Arsenal's all-time leading scorer with 226 goals in all competitions. The Frenchman won two league titles and three FA Cups with the gunners shoulder to shoulder; he was twice nominated for the FIFA World Player of the Year, was named the PFA Players' Player of the Year twice, and the Football Writers' Association Footballer of the Year three times. Henry spent his final two seasons with Arsenal as club captain, leading them to the UEFA Champions League final in 2006. In June 2007, after eight years with Arsenal, he transferred to FC Barcelona for a fee of 24 million.
Henry has enjoyed similar success with the French national squad, having won the 1998 FIFA World Cup and Euro 2000 (the Delaunay Cup). In October 2007, he surpassed Michel Platini's record to become France's top goal-scorer of all time. Off the pitch, as a result of his own experience, Henry is an active spokesperson against racism in football. His footballing style. and personality have ensured that he is one of the most commercially marketable footballers in the world; he has been featured in advertisements for Nike, Reebok, Renault, Pepsi and Gillette.
When did Thierry Henry first appear in a professional football game?
A.1990.
B.1994.
C.1998.
D.1999

Alzheimer’s Disease: Are We Close to Finding a Cure?
First described in 1906 by Dr.Alois Alzheimer, Alzheimer s disease is the most common form. of dementia, accounting for around 60%–80% of cases.It is characterized by problems with memory, thinking and behavior.Onset is most common in individuals aged 65 and over, although people in their 40s and 50s can develop what is classed as early - onset Alzheimer’s.
Alzheimer’s is a progressive disease, meaning memory loss is mild in the beginning, but it worsens over time to the extent that individuals are unable to have conversations or respond to their surroundings.There are treatments that have been approved by the US
Food and Drug Administration (FDA) for Alzheimer’s.For example, cholinesterase inhibitors and memantine can help treat memory and thinking problems.But these drugs just help manage the symptoms; there is currently no cure for the disease.
Current Alzheimer’s prevalence in the US makes it the 6th leading cause of death, killing more than half a million seniors every year.To put this in perspective, Alzheimer’s disease currently kills more people each year than prostate cancer and breast cancer combined.There is no doubt that scientists across the world are working hard to find ways to prevent, treat and cure this debilitating condition.Hardly a day goes by without coming across a report about how scientists restored memory and learning deficits in Alzheimer’s mouse models, how vitamin D deficiency could increase the risk of developing dementia, and how DNA methylation in the brain is linked to Alzheimer’s.But what have these studies taught researchers about Alzheimer’s so far?
Preventing and Targeting Plaques and Tangles
As with all diseases, knowing exactly what causes Alzheimer’s is key to identifying ways to prevent and treat the condition.Past research has indicated that Alzheimer’s occurs when two abnormal brain structures — plaques and tangles —damage and kill nerve cells, causing the memory, thinking and behavioral problems associated wit
1.Dementia is not a single disease in itself, but a general term to describe symptoms of impairment in memory, communication, and thinking.()
2.The FDA - approved drugs, like cholinesterase inhibitors and memantine, can cure Alzheimer’s disease.()
3.chronic sleep deprivation may cause these abnormal brain structures.()
4.Tangles are fragments of a protein called beta - amyloid, which build up in areas between nerve cells.()
5.As a result of Alzheimer’s research, there are an array of drugs in development that scientists believe have great potential to effectively treat the disease.()

It currently produces and sells 80,000 units per annum, with production of them being restricted by the short supply of labour. Each control panel includes two main components – one key pad and one display screen. At present, Robber Co manufactures both of these components in-house. However, the company is currently considering outsourcing the production of keypads and/or display screens. A newly established company based in Burgistan is keen to secure a place in the market, and has offered to supply the keypads for the equivalent of $4·10 per unit and the display screens for the equivalent of $4·30 per unit. This price has been guaranteed for two years.
The current total annual costs of producing the keypads and the display screens are:
Notes:
1. Materials costs for keypads are expected to increase by 5% in six months’ time; materials costs for display screens are only expected to increase by 2%, but with immediate effect.
2. Direct labour costs are purely variable and not expected to change over the next year.
3. Heat and power costs include an apportionment of the general factory overhead for heat and power as well as the costs of heat and power directly used for the production of keypads and display screens. The general apportionment included is calculated using 50% of the direct labour cost for each component and would be incurred irrespective of whether the components are manufactured in-house or not.
4. Machine costs are semi-variable; the variable element relates to set up costs, which are based upon the number of batches made. The keypads’ machine has fixed costs of $4,000 per annum and the display screens’ machine has fixed costs of $6,000 per annum. Whilst both components are currently made in batches of 500, this would need to change, with immediate effect, to batches of 400.
5. 60% of depreciation and insurance costs relate to an apportionment of the general factory depreciation and insurance costs; the remaining 40% is specific to the manufacture of keypads and display screens.
Required:
(a) Advise Robber Co whether it should continue to manufacture the keypads and display screens in-house or whether it should outsource their manufacture to the supplier in Burgistan, assuming it continues to adopt a policy to limit manufacture and sales to 80,000 control panels in the coming year. (8 marks)
(b) Robber Co takes 0·5 labour hours to produce a keypad and 0·75 labour hours to produce a display screen. Labour hours are restricted to 100,000 hours and labour is paid at $1 per hour. Robber Co wishes to increase its supply to 100,000 control panels (i.e. 100,000 each of keypads and display screens). Advise Robber Co as to how many units of keypads and display panels they should either manufacture and/or outsource in order to minimise their costs. (7 marks)
(c) Discuss the non-financial factors that Robber Co should consider when making a decision about outsourcing the manufacture of keypads and display screens. (5 marks)
