Dear Sarah,
Thankyou for your letter asking about the rebuilt Qianmen street. Here is something about it. It is more than 800 meters long with a history of over 600 years and 300 shops around it. It lies south of the Tian'anmen Square and its traffic is very convenient. You can take several buses such as No. 17, 69,59, etc. to get there. You can also take No.2 subway. There are many attractions here.
For example, you can walk on the pedestrian street to experience the rich culture of Beijing and buy something you like. You can also take trolley car to go wherever you'd like to. Besides, there are some tea shops and theaters where you can relax yourself after some walk.
Looking forward to your coming.

Ⅲ .阅读理解
A
One of the keys to being successful in what you do is persistence. Once you have determined exactly what you want to achieve, you must take massive action on a constant basis in order to succeed.
One of the things you'll notice on your journey towards your goal is roadblocks. That is, you will come across obstacles that seem to jump out of nowhere in an attempt to discourage your progress. Actually, they are a part of life. Everyone would have every success that ever wanted if there were no obstacles. Your job is to be persistent and work through obstacles. If you find little or no obstacles along the way, you are not really challenging yourself. And when you do reach your goal, you won' t experience the feeling of “sweet success”. Make your goal a challenging one!
If you take the time to study a successful person, you will learn that the vast majority of them have had more “failures” than they have had “successes”. This is because successful people are persistent; the more they stumble,_ the more they get right back up and try again. On the other hand, people who don' t get back up and try again never reach success. For example, Walt Disney was turned down 302 times before he got financing for his dream of creating the “Happiest Place on Earth” . Today, due to his persistence, millions of people have shared “the joy of Disney”. Colonel Sanders spent two years driving across the United States looking for restaurants to buy his chicken recipe. He was turned down 1 009 times! How successful is Kentucky Fried Chicken today!
Having known these facts, keep in mind that you must constantly reevaluate your circumstances and the approach you are using to reach your goal. There is no sense in being persistent at something that you are doing incorrectly! Sometimes you have to modify your approach along the way. Every time you do something you learn from it, and therefore find a better way to do it the next time.
Today is the day to begin your journey, using consistency and persistency, towards tomorrow's successes!

B
Everyone becomes a little more forgetful as they get older, but men's minds decline more than women's, according to the results of a worldwide survey.
Certain differences seem to be inherent in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills), while women tend to excel (擅长) at recalling information from their brain's files (helpful with language skills and remembering the locations of objects).
Many studies have looked for a connection between sex and the amount of mental decline (衰退) people experience as they age, but the results have been mixed.
Some studies found more age－related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline. Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, “so they're the ones that may not have shown such cognitive decline，” said study team leader Elizabeth of the University of Warwick in England.
People surveyed completed four tasks that tested sex－related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category (范畴) as possible in the given time, e．g. “object usually colored gray”， and recalling the location of objects in a line drawing. The first two were tasks at which men usually excel; the latter are typically dominated by women.
Within each age group studied, men and women performed better in their separate categories on average. And though performance declined with age for both genders, women showed obviously less decline than men overall.
6. The underlined word in the second paragraph means______.
A. natural B. great
C. obvious D. absolute
答案及解析：
6．A。词意猜测题。男女大脑的思维在某些方面的差异是天生固有的。
7. According to the passage, which of the following can NOT be typed into the same category?
A. Cloud. B. Sheep.
C. Trees. D. Goose.
答案及解析：
7．C。推理判断题。根据文章第五段可推断出选项中这类物体是以白色为限定范畴的，故选项C为答案。
8. Which of the following statements is true according to the article?
A. Men do better than women when it comes to learning English.
B. Women stand out at remembering people's names.
C. Men excel at typing as many words in a particular category as possible in the given time.
D. Women excel at dealing with mathematic problems.
答案及解析：
8．B。推理判断题。男性在推理和空间思维方面占优势，女性在提取大脑中储存的记忆信息方面占优势。故答案为B。
9. One important factor that affects the correctness of the results is that ______.
A. the old men tested may not have shown such cognitive decline
B. people surveyed are all old
C. people taking part in this test come from all over the world
