Mexico City is truly one of the most amazing cities in the world with a mixture of both the old and new world. From the moment your plane starts to land in this vast city, you know that your trip will be quite an adventure.

Once in your taxi and the moment you leave the airport, you are amazed at the large amount of slow traffic. The volume of the traffic can be stressful to some.

The "Paseo de la Reforma (改革大道)", running southwest across the city, is one of the major tourist and business areas in Mexico City with many high quality hotels only walking distance from great restaurants and other tourist attractions. The only problem you will have is trying to see all of these sites during your vacation time.

One of the most popular attractions in this area is the National Museum of Anthropology along the northwest part of the street. There are thousands of artifacts on display showing the history of the area and numerous items found from the many Aztec sites in the area. Walking southwest from the museum, you will soon reach the Mexico City Zoo, which is a great place to spend an afternoon.

Across the street from the museum is the Chapultepec Castle, once an important site in the Mexican-American war. It's also a good idea to take the train up the hill to where the castle is located as the hill is steep (陡峭的). It's important to keep in mind that Mexico City is over 7,000 feet above sea level and some feel it difficult to breathe when walking.

You can take a taxi to the Coyoacan market during the evening on a weekend. It's a great place to get some cheap souvenirs to bring back home and to enjoy some traditional Mexican cuisine. However, you must be careful where you eat and that the meat is well cooked.

The tourists in Mexico City may not be satisfied with______.

A．the high speed of the traffic                      B．the heavy traffic of the city

C．the polluted air in the city                                D．their safety in the city

From the third paragraph, we can learn that______.

A．the number of the city attractions can't meet the needs of the tourists

B．it is convenient for tourists to visit the city from where they stay

C．tourists have problems when visiting the sites in Mexico City

D．tourists often have their three meals in the high quality hotels

Which of the following shows the correct positions of the following places?

P = Paseo de la Reforma            M = the National Museum of Anthropology

C = the Chapultepec Castle        Z = the Mexico City Zoo

Which of the following attractions may interest those who want to study the military (of the army) history of Mexico City?

A．The National Museum of Anthropology.    B．The Coyoacan market.

C．The Chapultepec Castle.                           D．The Aztec sites.

Hundreds of years ago, life was much harder than it is today, people did not have modern machines. There was no modern medicine, either.
Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and affects our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It affects every living thing in the world.
Cars, planes and factories all pollute our air every day. Sometimes the pollution is so thick that it is like a quilt(被子) over a city. This kind of quilt is called smog.
Many countries are making new laws to fight pollution. Factories must now clean their water before it is thrown away; they mustn’t blow dirty smoke into the air.
We need to do many other things. We can put waste things in the dustbin and not throw them on the ground. We can go to work by bus or with our friends in the some car. If there are fewer people driving, there will be less pollution.
Laws are not enough. Every person must help to fight pollution.
49. Life was harder hundreds of years ago because____________.
A. the weather was bad             B. there were no cities
C. people had no modern machines    D. people couldn’t make machines  
50._______ makes the rivers and lakes dirty.
A Swimming.   B Polluted water   C. Growing population   D. Warmer weather
51.More and more people become angry easily because __________.
A. they can’t get enough money           B. They are often hungry
C. there’s much traffic on the roads        D. there’s much noise around them
52 The writer of the passage thinks__________.
A. everyone should do something to fight pollution
B. all the laws can stop factories going on polluting

A
　　Soon it may be harder to stop and smell the roses.
　　Growing levels of air pollution from power plants and automobiles have reduced flower fragrances (芬芳) by up to 90 percent in the US.That is compared with pre-industrial levels,a new study has found.
　　The trend is unpleasant for human noses,but may be life - threatening for bees and butterflies.
　　"Many insects find flowers by folowing the scent(香味) produced by those flowers," said the studies lead author Jose D.Fuentes,an environmental scientist at the University of Virginia.
　　"The increasing pollution makes it difficult for them to locate the flowers and feed on their nectar(花蜜)."
　　Scientists have alrady known that flowers produce scent molecules(分子) that bond with pollutants.The process breaks down the plants' sweet smell.
　　With more pollution in the air,the scent molecules don't remain effective as long and travel shorter distances on the wind.
　　The new study suggests that in the mid - 19th century,when pollution levels were first recorded,scent molecules would have been able to travel some 1,000 to 1,200 meters.
　　Today,in the polluted air found downwind of large cities,scentst may only make it some 200 to 300 meters.
　　The report was recently published in the journal,Atmospheric Environment.
　　Bee farmers have reported that bee populations are dropping dramatically in many parts of the world in recent years. Could these missing scents be a factor?
　　Scientists trying to hind the cause of bee population declines have blamed bacteria,pesticides,and even cellphone radiation.
　　Jay Evans,an entomologist(昆虫学者) at the US Department of Agriculture's bee research laboratory,was interested in the new study.But he says he hasn't seen bee behavior that suggests trouble with scents.
　　"Over the last couple of summers I don't think the bees in this area were bringing in much less food,"he said.
　　"It might be that they had to work harder,but it seems like as long as there were bees to collect food they were finding flowers somewhere."
　　But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats.
　　"The effects shown in these studies will simply exacerbate whatever the bees are going through right now,"he said.
　　"It's something that is really worthwhile paying attention to."
　　56.What's the passage mainly about?
　　　A.How greatly air plooution affects our lives.
　　　B.Effects of air pollution on bee populations.
　　　C.Measures to fight air pollution.
　　　D.The rapid decline of bee populations in the world.
