A
As I stuck in the mud (泥), with my bike on top of me, I wondered what had forced me to come here. Madagascar is not a good place for a cycling holiday: one of the world's poorest countries, only 11 percent of roadway is paved (铺). South of the town of Antalaha, where I started, the road was in worse condition.
I appeared from a week in the wilderness and reached the start of the Route National 5 at Maroantsetra, but my dream of a smooth road and speed was suddenly destroyed by mud. The “worst road in the country” changed my bicycle into a burden (负担) for days. Finally, I_was_claimed_by_the_road. Tired. Alone.
As I wiped (擦) the mud from my face and looked upwards, I was greeted by a Malagasy man. He helped me stand up and smiled playfully while he pointed to my bike, which sat next to his. I started again. But I fell again in the mud. Angrily, I told him to go on, but if he understood he showed no sign of it. His smile forced me back onto the bike. We continued like this for hours. But I fell less. Studying my quick guide, slowly I learned. As we passed through a village, a group of children saw me and shouted loudly. His only words were: “Their parents tell them while people steal and eat them. Funny, no？”
I tried to ask why, but he had already set off. I tried to catch up; as I got closer, he took it as a challenge and sped up. We raced along the road. I rode a little faster and I was just behind, about to catch up with him. With a smile, he sped up and was away, leaving me breathless.

Raccoons are smaller relatives of bears. They are native to North America, but they can also be found in Asia and Europe. Raccoons live in wooded areas close to water, but they can be often found near urban areas. There are about 7 different species of raccoons. Pygmy raccoon is the only endangered species.
Raccoons usually reach 40 to 70cm in length and weigh between 5­26kg. Raccoons that live in colder climates are larger and heavier. They have grayish fur, black masks around eyes and long tails covered with black and brown bands. Because of their tails, they are also called “ringtail”．
Raccoons_are_omnivores. They like to eat insects, eggs, small mammals, fruit, berries garbage, and so on. Raccoon's hands look like human's. They each have five fingers and are used to collect food, open shells, door or trash cans. Raccoons often place food in water before they start to eat it. They have highly sensitive sense of touch and water increases their sensitivity even more. By touching the food, they get better insight about things they will eat.
They are easily adaptable (适应的) to various environments. They can live in hollow (中空的) trees equally happily like they can in useless cars. Raccoons live on their own and hunt at night. They don't hibernate (冬眠), but they spend the coldest days of winters in their holes.
Mating (交配) season takes place from January to mid March. Two months later, female will give birth to 3­4 babies. Their tails don't have bands, and the mask around eyes is still missing. Mother is very protective and she will teach them how to survive and what to eat as they become­ready to leave the hole. Raccoons usually can live only 1.8 to 3.1 years in the wild, but they can live up to 20 years at a zoo.
Raccoons can pass rabies, a kind of disease, to home­raised animals and people, which is very dangerous. What's more, their waste often has roundworms.

Angus, Doris, Gabriel and Kamil are some of the 21 names that have been chosen to be given to storms in the UK in the 2016/17 season.
The Met Office, the UK's national weather service, decided to give storms boys' and girls' names in 2015 in the same way as they did in America.
The Met Office hopes that naming big storms will mean people are more aware (意识到) of them and how dangerous they can be. Derrick Ryall, from the Met Office, said, “We have seen how naming storms elsewhere in the world raises people's awareness of storms before they break.”
In the past, the same UK storm could be given different names by different organisations. “We noticed that many organisations during the last couple of winters, when we have had bad storms, started giving names to them. Think back to the St Jude's Day storm in 2013, and the so­called Hurricane Bawbag in Scotland in 2011. But it led to confusion (混乱)，” a Met Office spokeswoman said.
According to the Met Office, there is a name for each letter of the whole alphabet (字母表), except for Q，U，X，Y and Z. That is the same as the naming tradition used in America. And not all storms will be big enough to get names — only those expected to cause great damage.
If there are more than 21 storms in a year, the Met Office will start again with another name beginning with “A”. However, according to Met Office spokeswoman Lindsay Mears, “It's unlikely we would get through the whole alphabet in one season. We had 14 storms in the very bad winter of 2013/14, and if the naming system had been in operation then we wouldn't have used the whole alphabet.”
【语篇解读】　本文是一篇说明文。文章主要介绍了英国为暴风雨命名的情况。
9．Why are storms in the UK named?
A．To increase public awareness of them.
B．To remind people of their short stay.
C．To follow what other countries did.
D．To meet the needs of its people.
答案与解析：A　推理判断题。根据第三段中的“naming big storms will mean people are more aware of them and how dangerous they can be”和“how naming storms elsewhere in the world raises people's awareness of storms before they break”可推断，英国为暴风雨命名是为了增强人们对暴风雨的了解和防范意识。故选A项。
10．Examples are given in Paragraph 4 to show ________.
A．there're many storms to name in a year
B．organisations named storms differently
C．some storms' names are similar to others'
D．some storms' names are hard to understand
答案与解析：B　推理判断题。本段的主题句是“In the past, the same UK storm could be given different names by different organisations，”下文通过举例说明该主题。故选B项。
11．What do we know about the names given to storms?
A．Storms will be given names whatever their sizes.
B．Serious storms will be given boy's names.
C．21 letters will be used to begin the names.
D．21 names will be given at most in a year.
答案与解析：C　细节理解题。根据倒数第二段中的“there is a name for each letter of the whole alphabet, except for Q, U, X, Y and Z”和最后一段中的“If there are more than 21 storms in a year”可知，在为暴风雨命名的时候，会以21个字母(字母表一共26个字母，除了Q，U，X，Y，Z之外还有21个)开头。故选C项。
12．What can be learned from Lindsay Mears?
A．There are not too many big storms yearly.
B．Action will be taken to prevent storms.
C．There are usually 14 storms in a year.
D．The naming system will not change.
答案与解析：A　推理判断题。根据最后一段中的“Lindsay Mears”所说的“It's unlikely we would get through the whole alphabet in one season. We had 14 storms in the very bad winter of 2013/14... we wouldn't have used the whole alphabet”可推断，她认为英国每年不会发生那么多暴风雨，因此不会使用完21个字母作为名字的开头来命名暴风雨。故选A项。
