【题目】Each Sunday, people can hear the music of the Mission Dolores Basilica in San Francisco. The Spanish missionaries(传教士)built the church in 1791. It was the start of a special kind of neighborhood: the Mission District.

The area is a place with a long and varied history. One community member says that its important for people to understand the many levels of history in the neighborhood. He feels that this knowledge is a big part of understanding what it means to be a real San Franciscan.

One of the most interesting parts of the district is its people. Over the years, immigrants have come to the area from Ireland, Germany, and Italy. But the most recent immigrants are mainly from Latin America. Its easy to see the style that these recent additions give to the neighborhood. You can see it in the art on the walls, taste it in the food, and hear it in the music!

Juan Pedro Gaffney, the director of the Spanish Choir(唱诗班)of San Francisco, says that the people there share the pain and the happiness of their friends and family members and that music has always been a basic part of cultural identity in the district. He feels that the music of the district is colorful and lively.

But it isnt just its music thats colorful and lively. Its art is full of life as well.

The local art community stays close to the areas culture and tradition. A local arts organization often leads people on walks through the district. They visit streets like Balmy Alley, which is famous for its murals (壁画). Even though the meanings behind the murals are always changing, they are still very powerful. One artist explains that they are fighting for fairness in the community and to help the environment through murals. Apparently, theyre something the community likes.

Many of these artists feel that the district is a successful neighborhood where new immigrants are welcome. People see that theyre not so different from each other, says one artist. There are a lot of things that bind(捆绑)the immigrants through culture and tradition.

【题目】The weather predictions for Asia in 2050 read like a story from a doomsday movie.

Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring.In the decades to come, Asia—home to more than half the world's 63 billion people—will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels.

"It's not a pretty picture," said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam.Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.

Already, changes are being felt in Asia but worse is likely to come.Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters.According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate or build sea defenses, storms will become stronger and insects and water-borne diseases will move into new areas as the world warms.

All this comes on top of rising populations and demand for food, water and other resources.Experts say environmental worsening such as deforestation and pollution will likely enlarge the results of climate change.

In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two - thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill.

The year before, a winter cold strike and a summer heat wave killed more than 2,000 people in India.

【1】This passage is mainly about ____

A.present situation and predictions of environmental problems in Asia.

B.the weather predictions for Asia in the future and the reasons

C.how to improve our environment

D.reasons why the world will no longer be suitable for us to live in

【2】In the future the Asian farmers will have to face the following except ____

A.food shortages B.wars

C.droughts D.floods

【3】The underlined word "doomsday" in the first paragraph may mean____

A.the hell B.the end of the world

C.a great world war D.mystery

【4】Which of the following is NOT true according to the passage?

A.Asian climate will change greatly.

B.Some islands may be flooded in the future.

C.People may meet with some new diseases resulting from water.

D.More than 50 million people have been ill in Asia the year before.

【题目】As more people use smart phones to pay bills and store personal information, strict password security has become more important than ever. A new study shows that free-form gestures–sweeping fingers in shapes across the screen of a smart phone—can be used to unlock phones. These gestures are less likely to be observed and reproduced by others than traditional typed passwords.

“All that it takes to steal a password is a quick eye,” said one of the researchers of the study. “With all the personal information we have on our phones today, improving their security is becoming increasingly necessary.” In developing a secure solution to this problem, the researchers studied the practicality of using free-form gestures. With the ability to create any shape in any size and location on the screen, the gestures were popular as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity.

The researchers carried out a create-test-retest experiment where 63 people were asked to create a gesture, recall it, and recall it again 10 days later. The gestures were captured on a recognizer system designed by the team. Using this data, they tested the complexity and accuracy of each gesture using information theory. The result of their analysis is that people are favorable to use free-form gestures as passwords.

To put their analysis into practice, the researchers then had seven students in computer science and engineering, each with considerable experience with touchscreens(触摸屏), attempt to steal a free-form gesture password by observing a phone user secretly. None of them were able to copy the gestures with enough accuracy. The gestures appear to be extremely powerful against attacks.

Though the testing is in its early stage and widespread adaptation of this technology is not yet clear, the research team plans to continue to analyze the security and management of free–form passwords in the future. They believe this is the first study to explore free-form gestures as passwords. They will soon publish their findings.

1What can we learn about free-form gestures?

A. They are improving mobile security in a way.

B. Users will have to make use of simple gestures.

C. They will never be copied by others.

D. Users must move their fingers in fixed shapes.

A. template B. application C. accuracy D. security

3According to the text, the researchers think that ________.

A. it is easy to steal any password with a quick eye

B. better ways of setting passwords should be developed

C. people had better not use smart phones to pay bills

D. personal information should not be stored in a phone

4The main purpose of the text is to ________.

A. advise people to use free-form gestures

B. discuss whether smart phones are safe

C. talk about the practicality of passwords

D. introduce the study of a new password
