Nowadays women are playing a much more important part in society. More and more women are working like teachers, scientists and even leader. Almost all jobs that were used to be done by men are done perfectly well by women. Women are no longer looking down upon in society. With the changes in their social role, women’s position in the family have been improved as well. It’s hard to see the phenomenon which the wife is busy while the husband is sitting in an armchair, watching TV. In spite of all these changes, the great number of men still guard his rights. They thought of women as incapable creatures. Sometimes few women are allowed attend important meetings. This is the problem we should try to solve now.

However urban life strikes you, cities worldwide have been growing ever more rapidly. Some of this growth has occurred in the developed world, but the most dramatic increase has been in the Third World. Almost all the world’s population growth over the next 30 years will take place in the cities of developing countries

By the year 2030, for the first time in history, 60 percent of the world’s people will be living in cities.

This is actually good news in some ways. “Cities are the fundamental building blocks of prosperity,” says Marc Weiss, chairman of the Prague Institute for Global Urban Development, “ both for the nation and for families.” Industrial and commercial activities in urban areas account for between 50 and 80 percent of the gross domestic product (GDP) in most countries of the world“ there’s the crazy notion that the way to deal with a city’s problems is to keep people out of them,”Weiss continued. “But the problems of the rural life are even more serious than those of the city.” For better or worse, urban-watchers are clear on one point: The quality of life for most people in the future will be determined by the quality of cities. Those cities will be bigger than ever. And yet, population numbers by themselves don’t determine a city’s prospects; after all, Addis Ababa, Ethiopia, and Hamburg, Germany, have the same population. Nor is explosive growth necessarily the determining factor. “City problems,” one authority points out, “mostly have to do with weak, ineffective, and usually unrepresentative city governments.”

A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to evade policemen after a bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into the home of Mary Parnell. Police say he didn’t touch Parnell but that she died after suffering a heart attack that was caused by terror. Can the guy be held responsible for the woman’s death? Prosecutors(公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime like robbery—even if he or she doesn’t kill someone on purpose.

But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.

Absolutely, no question about it.

The body has a natural protective method called the fight-or-flight response(战或逃反应), which was originally described by Walter Cannon，the chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the autonomic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to primitive humans. However, in the modern world there is obvious decline of the fight-or-flight response.

The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is toxic in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death. Kidney failure, liver failure, those things don’t kill you suddenly.

By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in intercourse or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead. For about seven days after the 9/11 terrorist attacks on the World Trade Center and Pentagon there was an increase of sudden cardiac death among New Yorkers.

1. Why the Charlotte, N.C., man was charged?

A. Because he threatened the policemen to kill an old woman.

B. Because he caused an old woman’s terror and she died.

C. Because he beat an old woman and caused her heart attack

D. Because he murdered an old woman while robbing a bank.

2. Which of the following about the fight-or-flight response is true?

A. The fight-or-flight response was raised and proved by Martin A. Samuels.

B. It is a natural protective method that can’t be found in all creatures but humans.

C. The ancient humans had a superior fight-or-flight response than modern ones.

D. The fight-or-flight response is beneficial to both our actions and organs.

3.What activity can we infer is less likely to damage the organs?

A. Winning a big lottery. B. Missing a dead family.

C. Watching a horror movie. D. Listening to a sweet song.

4. The purpose of the passage is_________.

A. to explain why people will die of a heart attack

B. to offer some advice on protecting us from heart failure

C. to compare different kinds of feelings to cause a death

D. to show strong emotions can cause a sudden death

“I never expected that I would be so busy. Why can’t there be 25 hours in a day?” complained Liu Ran in Hong Kong as mid – term exams were going on.

The 18 – year – old girl was Shandong Province’s top scorer in this year’s college entrance examination. After graduating from Tai’ an No. 1 High School, she chose the Chinese University of Hong Kong, although two famous universities in mainland promised her a place.

“I want to experience a more international school and social life in Hong Kong. I’m majoring in（主修）journalism, so Hong Kong will surly help widen my horizons,” Liu said.

It is two months since Liu first set foot on Hong Kong. She missed home a lot at the beginning, because of the food and language problems.

“The canteen offers mostly Western or Guangdong food, but it’s convenient to cook for ourselves in our dormitory if we like. People speak Cantonese and almost all classes are in English,” Liu explained.

Her English and Cantonese are now both improving, but she still needs more time to adapt to the new environment.

“I’m happy that I made the right decision to study here. With a mix of the Eastern and Western cultures, there is so much to discover and learn,” she said.

Liu has 18 credit hours of classes every week and 23 non – credit hours every other week. She has signed up for four associations including the Chinese Language Debating Team and the drama club. Essays, book reports and presentations also take plenty of time to prepare.

1.What would be the best title for the text?

Everyday, 340 million people speak it. One billion people are learning it and it is said that by 2050, half of the world’s population will be using it. What are we talking about? That is the global language—English.

The English language started in Britain in the 5th century. It is a mixed language. It was built up when German. Scandinavian and French invaders settled in England and created a common language for communication.

Today it is the official language of the UK, the USA, Australia, New Zealand, Canada, South Africa and Ireland as well as many islands in the Caribbean. Many other countries and regions use it for politics and business, for example, India. Pakistan, Nigeria and the Philippines. English is also one of the official languages of Hong Kong.

But global advertising and pop music mean that in most countries, you will see or hear some English. Thanks to McDonalds, we all know about “burgers”. “fries” and “milkshakes”. Songs by Madonna, Britney Spears and Celine Dion are in English. We can sing along, even if we do not understand what we are singing!

English is a messy (杂乱的) language. Every year, dictionaries include new words that talk about popular culture, for example, computer-related words such as "blogging", "download" and "chartroom". Also included are words that teenagers use. Who does not know “cool”, “OK” and “hello”?

Other languages also influence English. Many English words come from French. Words like “café” and expressions like “c'est la vie” (that is life) are all part of the English language. On the other hand, the French language includes English words like "le weekend" and "le camping". German words are also part of English. Words like "kindergarten" come from the German language.

Recently, British people have become interested in “yoga”. But the word comes from an ancient Hindu language in India.
