Question: Article: It does not come as a surprise that Dubai has a growing problem with "tragic". The local rulers have explored all the conventional ways to get traffic moving again,including higher prices for parking,fuel and insurance. But at a recent conference in Hamburg, Hussain Lootah said that the city may adopt a more strict approach: setting an income level for vehicle ownership. Mr Lootah's approach is unlikely to be copied widely, but mayors of other big cities around the world are starting to think about taking severe actions of their own, including complete car bans in inner cities.But the efforts may not be enough to reduce traffic and pollution. The problems will only get worse: the number of vehicles sold globally each year will grow from around 80 million today to more than 100 million by the end of the decade, according to IHS Automotive. There are already a handful of car-free communities around the world.But these are typically small and often tourist destinations that seek to create a throwback(;) in time, such as Sark Island, in the English Channel. The largest car-free urban area is probably Venice, where it is impossible to build roads and bridges to link the more than 100 small islands the city sits on. Yet pedestrian malls and other car-free zones keep popping up in cities around the world. Some cities are considering ways to limit central city access to "green" machines, such as battery-electric vehicles. Hamburg is perhaps the furthest along. Such extreme plans may fly in a city such as Hamburg. But in many other cities the political resistance even to less far-reaching measures is hard to overcome. Michael Bloomberg, New York's former mayor, tried twice to introduce a jam charge for much of Manhattan, but his plans were rejected by state lawmakers.
Question: It is still hard to reduce traffic problems, because _ .
Options: (A) Mr Lootah's approach will be copied widely. (B) mayors take gentle measures toward them. (C) more vehicles will be sold globally each year. (D) complete car bans in inner cities are not made.

Answer: C

Question: Article: I live in north Celebes which is near Philippines. Since early December 2010 most tropical regions have been frequently hit by rain. Just like my hometown, tropical regions only have two seasons, including the dry season that usually starts from April to September and the wet or rainy season which usually happens from October to March. But, it could be _ Sometimes the rainy season can come a month earlier or later. It can be prolonged even more than 4 months and so can the dry season. Even during the dry season, rain can occur several times in certain areas. The prolonged dry season in tropical areas usually causes a lot of losses. It will be very harmful to local farmers, because most of the tropical areas sre regions of the developing countries. Sometimes agricultural and plantation crops will be damaged because of so much dry land and the fact that the river used to flow the water for rice fields are also dry. Rain is very important for plants because rain contains many nutrients that plants are in great need of. What's more, if the prolonged rainy season arrives and then floods usually occur in certain areas of low lands. Even for the capital city of Jakarta floods have struck several times during the prolonged rainy season. In addition to floods, the rainy season can cause many diseases. During the dry season, diseases are usually caused by mosquitoes such as dengue fever. While in the rainy season, people who have the weak immune will be more easily attacked by some diseases such as flu, fever, diarrhea, and much more. If you live in the other places and want to travel to the tropical regions, make sure that you have known much about the season and the effect for these months in which you want to travel as tourists. Only in that way, can you at least prepare to deal with tropical weather.
Question: We can learn from the passage that in the wet season, _
Options: (A) the capital of Jakarta is flooded every year (B) more crops will die after being flooded for so long. (C) mosquitoes will spread more diseases among the crowd. (D) people with weak immune might be attacked by some diseases

Answer: D

Question: Article: Must-Read about Notting Hill Carnival Route The carnival procession itself begins at 9am on both Sunday and Monday. It starts on Great Western Road, winding its way along Chepstow Road, then on to Westbourne Grove, and then down Ladbroke Grove. See our Notting Hill Carnival map for the full route. Bus While extra services will be in operation, no buses will enter the Carnival area from first thing Sunday morning until the first service on Tuesday morning. On both days bus services begin from Notting Hill Gate in the south and from Harrow Rd (close to Elgin Avenue) in the north. Bike Last year the nearest bike-parking stations - Chepstow Villas and Pembridge Road - were removed for Carnival, so don't rely on being able to park your bike nearby this year. Safety Avoid carrying expensive items, such as jewellery and digital cameras. Take a bag with a secure zip to keep your more valuable possessions in and avoid putting your valuables in your back pocket. Do tell police if you see an incident. Officers will be stationed throughout the Carnival area. Don't try to walk against the flow of the crowd, as you won't get far. Drink plenty of water on the day too, especially if the sun makes an appearance. Children Children's Day on Sunday is recommended for families as the smaller crowds and kid-friendly floats create a fun atmosphere. Arrange meeting points in case you become separated. The smaller the buggy , the better. Ear defenders may be necessary for very young children.
