13．On our journey to Australia last summer，our luggage was _____ at the customs．We were not allowed to carry food such as meat and vegetables．（　　）

20．All kinds of festivals and celebrations have held everywhere since ancient times．

10．Solid passes sound very well．Try holding a wooden stick against part of a machine，and place your ears against the stick．The movement of the ball-bearings（滚珠轴承） can be clearly heard．This is a good way of finding the exact source of trouble in a motorcar engine which sounds as if it is wrong and yet gives no information of where the trouble is．
It is probably a good thing that sound cannot travel through a vacuum（真空），for we are thus limited to earth-made sounds．The violent disturbances which are seen sometimes in the sun，for example，may affect our magnetism（磁力） and our radio．They do not affect our ears，which is a very good thing for our peace of mind．
If we have used our eyes and ears，we may have realized that sound takes time to travel through the air．The sound of thunder nearly always follows the lightning flash although they happen at exactly the same time．And the appearance of white cloud above a distant ship or train tells us，before anything is heard，that its whistle has sounded．Just how fast does sound travel through the air？
The speed of sound in the air at ordinary temperature is about 100feet per second，which is about one mile in five seconds or about 700miles per hour．The speed of sound increases slightly with a rise in temperature and falls with a decrease in temperature； it is not affected by the pressure of the air．

24．We never hear anything that happens on the sunA．
A．because of the vacuum between the earth and the sun
B．because we are only used to earth-made sound
C．because of the distance between the earth and the sun
D．because we are likely to enjoy our peace of mind
25．According to the passage，how fast does sound travel through the air at ordinary temperature？C
A．About 700meters per minute．
B．About 1，100miles per hour．
C．About 60，000feet per minute．
D．About one kilometer in five seconds．
26．How do temperature and pressure affect the speed of sound？D
A．The speed of sound increase with a rise in pressure．
B．The speed of sound decrease with a rise in temperature．
C．The speed of sound increase in lower temperature and greater pressure．
D．The speed of sound decreases with a fall in temperature．
27．The underlined sentence in the second paragraph means"D"．
A．thus we can hear anything but the sound made by the earth

D．thus we can only hear the sound made on the earth，not the sound coming from the outside．

17．A strange，new dilemma faces Chinese pedestrians：should you help an elderly person who has fallen into the street？The answer seems simple．Your conscience forces you to help someone in danger．But many Chinese are discovering that some of these injured people are scammers．They accuse good Samaritans（好心人） of having knocked them over in the first place，and they file complaints in hopes of receiving large amounts of compensation．
There are frequent reports on such incidents and following disputes．On Sept 8，a new case happened in Huainan，Anhui province．Yuan Chen，a 20-year-old college student from Huainan Normal University，claimed that she helped an injured elderly woman on the street．But the woman's family has demanded that Yuan take full responsibilities for the injuries．
Since the incident happened in the security cameras'blind spot，both sides are looking for witnesses to clear their names．The local police department is also investigating the case．But how can you possibly solve a case like this，where the only evidence comes from two conflicting viewpoints？
"This kind of cases should follow the principle of‘the burden of proof lies with the person making the claim'，"Ye Lin，a law professor from Renmin University of China，told China Central Television．The burden of proof means the collection of proof or evidence．In civil cases，"if you accuse someone of causing you harm or losses，you should collect convincing proof to back your claim，"said Ye．"If you cannot do that，the law will not be able to support your claim．"
The law may not resolve all the problems，however．Some elderly people choose to blackmail（敲诈） their helpers because they do not have health insurance．To prevent this，the country needs to put in place a better social security net．

12．Which of the following statements is TRUE according to the first paragraph？B
A．Conscience is troublesome because it compels you to help someone who will set you up in return．
B．Sometimes the warm-hearted are wrongly accused of having knocked others over．
C．It is advisable for Chinese people to turn a blind eye to someone in danger．
D．There's no doubt that the elderly usually fell down on purpose to claim compensation．
13．What does the sentence in paragraph 3"both sides are looking for witnesses to clear their names"mean？D

B．Both sides are in search of evidence that can clarify their opinions．
C．Both sides are in search of evidence that can wash away their crimes．
D．Both sides are in search of someone who can prove they are telling the truth．
14．What can we infer from Ye Lin，the law professor's words？C
A．Ye Lin thinks it is Yuan Chen who is responsible for gathering proof．
B．In civil cases，the accused should collect proof as well to reject the claim．
C．The principle regards the accused as innocent until convincing proof can be provided．
D．Since it is hard to collect convincing proof，both sides should take on the responsibility．
15．What is most likely to be written in the paragraph that follows？B
A．To make comments on this hot social phenomenon．
B．To emphasize the necessity of an improved social security system．
C．To analyze deep causes of the elderly blackmailing their helpers．
D．To illustrate the impact brought about by the blackmail on our society．

15．Kenya is losing an average of 100of its 2，000lions each year because of growing human  settlements，increasing farming，climate change and diseases，according to the Kenya Wildlife Service （KWS）．
"Lions have a special place in Kenyans'life，"said Paul Udoto，a spokesman for the organization．"Other than being the symbol of national strength，they are among the Big Five，a main attraction for visitors to Kenya．"
There were 2，749lions in Kenya in 2002and Uieir population dropped to 2，280by 2004  and to about 2，000today，according to KWS figures．
"The fall of the lion population is worrying and every effort needs to be made to make sure that Kenya either protects its population of 2000lions at present or increases the numbers to an ecologically acceptable level，"said Mr．Udoto．
"There is no doubt that the numbers are in free fall．Id be surprised if they even last as  long as 20years，"said Laurence Frank，project director of Living With Lions，a Kenya-based animal protection organization?i?Wen I first came here 30years ago，I would always hear lions roaring across the land at night and see their tracks in the morning．Now that is very rare．
"The reason is simple．As the numbers of people grow and the numbers of cows increase  they take up much of the lion's space．Alongside that there are other ways，including poisoning 9to kill lions．"
Animal lovers are making a new strategy to save the animals．Part of the measures will include tracking lions fitted with radio collars in the Amboseli area in southern Kenya，close to the border with Tanzania．
