Parkour (跑酷) is a new sport that is developing quickly in the world. The aim of parkour is to jump, climb or run over any all stair, or fence on your path easily. Usually, it is done in a city environment. Practicers take very wall or roof as their training place. If you have seen the beginning of the James Bond movie Casino Royale, then you have seen an excellent example of parkour.

David Belle, a young Frenchman, developed parkour in the 1990s. His father's experiences as a fireman as well as an acrobat(杂技演员)influenced him a lot. His childhood friend, Sebastien Foucan, is the actor in the movie Casino Royale with his parkour performance. Foucan is thought to have developed free-running, which is a more artistic and skillful type of parkour. David belle traveled to India and said one way he trained was by watching a physical one. The aim is to become so skillful, and it is almost unnecessary for you to think about the different actions in running through a path full of barriers(障碍物).

Parkour is not exactly a sport. It is not developed fro competition. It is more about learning to control mind and body in difficult situations. There are many basic movements in parkour. One example is where practicers swing through the narrow space between two bars while keeping their body level with the ground. This is called the underbar. Other movements are the tic-tac and the kong vault jump. Skillful practicers seem to get out of control of gravity.

The popularity has spread largely because of parkour videos and organizations on the Internet. And if you search on the Web, you will find parkour groups performing their skills near you.

There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

Food production

With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that---it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to" re-create forms and pieces" of food that are" exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

Sustainability(可持续性)

The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids( 水解胶体)from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原 料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

Nutrition

Future　 3D　 food　 printers　 could　 make　 processed　 food　 healthier.　 Hod　 Lipson,　 a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday 's bread from the supermarket, you' d eat something baked just for you on demand."

Challenges

Despite recent advancements in 3D food printing，the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste( 糊状物)before a printer　 can　 use　 them,　 and　 the　 printing　 process　 is　 quite　 time-consuming,　 because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients，because meat and milk products may easily go bad. Some experts are doubtful about food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

1.What benefit does 3D printing bring to food production?

A.It helps cooks to create new dishes.

B.It saves time and effort in cooking.

C.It improves the cooking conditions.

D.It contributes to restaurant decorations.

2.What can we learn about 3D food printing from Paragraph 3?

A.It solves food shortages easily.

B.It quickens the transportation of food.

C.It needs no space for the storage of food.

D.It uses renewable materials as sources of food.

3.What is the main factor that prevents 3D food printing from spreading widely?

A.The printing process is complicated.

B.3D food printers are too expensive.

C.Food materials have to be dried.

D.Some experts doubt 3D food printing.

4.What could be the best title of the passage?

A.3D Food Printing: Delicious New Technology

B.A New Way to Improve 3D Food Printing

C.The Challenges for 3D Food Production

D.3D Food Printing: From Farm to Table

The Internet is a growing new world that has been developing ever since it was created many years ago. The only reason Internet sales are not taxed (征税) is because we did not know the Internet would be used to sell products when it was created. Internet sales are no different than going into the store to buy the exact same product except for the fact that Internet sales are not taxed.

When buying online, people cannot see and touch the product the same way they could in a store. To fix this, customers are going into the store to see the product. Then if they like the product, they buy it online to save money on the sales tax. This is a form of tax evasion (逃税) if you ask me!

Everyone has to pay the tax in the store so they should have to pay taxes online as well. Also, the added money brought in through Internet taxing could help the government to fund (为……拨款) certain policies and other things that they could not do without the added funds. This could go toward the country’s schools or other things necessary for society to function well. These funds could be extremely beneficial because of the recession (经济衰退) that the country is in at this point. Internet taxing is a way to increase those funds and in turn improve the quality of life for all who live in that country.

In conclusion, there are many more positives than negatives in the argument over taxing Internet sales. I do understand that I may have to pay more if I want to buy something online, but the funds stay within my society and help my country. The added cost may hurt me at first but in the end, the funds will help me and others in our country.

1.The text mainly discusses _____.

A.whether it is a good way to buy things online.

B.whether Internet sales should be taxed.

C.why people love to buy things online.

D.why Internet sales are not taxed.

2.Internet sales are not taxed because _____.

A.selling online was unexpected. B.they are different from store sales.

C.people don’t know how to tax them. D.many people are against taxing them.

3.What can we learn from Paragraph 2?

A.Online shoppers find it difficult to buy satisfactory goods.

B.Customers get better products at a lower price online.

C.Problems related to online shopping are hard to fix.

D.Online shoppers probably try to avoid paying tax.

4.According to the author, taxing Internet sales _____.

A.is good for all people. B.can help the country out of the recession.

C.can help improve the quality of products. D.is beneficial to the development of Internet.

A new report says sea ice in the Arctic Ocean is melting more quickly than expected. American scientists say the ice is melting even faster than computer programs had estimated.

Scientists know that climate change has a major effect on the Arctic Ocean partly because sea ice is disappearing. They also know that areas of open seawater are expanding. Such areas are known to take in sunlight and increase temperatures. Scientists say this has helped to cause the loss of the Arctic’s ice cover.

For the study, the American scientists compared eighteen computer programs with observations made by satellites and other instruments. The Intergovernmental Panel on Climate Change used the computer programs to prepare its 2007 estimates of climate change.

The computer programs gave estimates of the amount of ice in the Arctic Ocean in the month of September. September is when the Arctic has the least ice, after the warm, summer months. The computer estimates suggested an ice loss of two and a half percent for every ten-year period between 1953 and 2006.

Newer studies of the Arctic have used information gathered by aircraft, satellites and ships. This information showed a loss of September ice cover of almost eight percent for every ten-year period between 1953 and last year. This means the ice is disappearing about thirty years faster than the computer programs estimated.

The scientists say the programs might not have recognized the full effect of increased carbon dioxide and other gases in Earth’s atmosphere. They say their study suggests the gases may have more of an effect than had been thought.

1.It is reported that sea ice in the Arctic Ocean is melting more quickly than expected mainly because _________.

A. climate change                        B. sea ice’s disappearance

C. seawater’s expansion              D. the loss of the Arctic’s ice cover

2. How did the scientists draw the conclusion that sea ice in the Arctic Ocean is melting more quickly than expected?

A. The scientists have been observing the Arctic Ocean for many years.

B. The scientists have compared the computer programs with observation made by satellites and other instruments.

C. The scientists have figured out many numbers with the help of computer.

D. The scientists have found that the seawater take in sunlight and increase temperatures.

3.If the ice melts at the present speed, by the end of this century the ice loss in the Arctic Ocean will be _________ according to newer studies.

A. 22.5%                B. 35%          C.72%         D. 100%

4.Which of the following is TRUE according to the passage?

A. The figures of the computer estimates are wrong.

B. Scientists study climate change through studying sea level.

C. Newer studies show gases may have more effect on sea ice in the Arctic Ocean.

D. The ice is melting even faster than satellites have estimated.

5.This report mainly warns human to _________.

A. prevent the sea ice in the Arctic Ocean from melting any more

B. pay more attention to the loss of the Arctic’s ice cover

C. take necessary steps to protect the environment of our earth

D. stop summer sea ice in the Arctic from disappearing so fast

A new research shows that in Britain more and more people are returning to the old tradition that the whole family have a meal at table. Worrying about the obesity and breakdown of a family, people change their eating habits so greatly, according to analysis. They find the number of the family having a meal together increases by 5% from 2002 to 2004, and most people who have meals with their family come from the rich social class.

The new discovery makes doctors and the people struggling against obesity extremely excited. Giving up the tradition that the whole family have a meal together is exactly one of the reasons for a series of problems including children’s overweight. If a child has a meal in front of the television or the computer alone, he will often eat some fast food.

Jason Collins is one of the persons returning to the old tradition. Collins is a manager of a bake(烘面包) house. He finds after he gets used to having a meal at home with his child, the child becomes much more obedient(听话的). Dr. Jin is a child psychologist, and she expresses welcome to this result of the study.  She says it can make parents have a very good chance to chat with the child when the whole family have a meal together.

1. What makes people change their eating habit back to the old tradition in Britain?

2. We can infer from the passage that _______.

3. How do the people who hope to lose weight feel about the new discovery?

4. Which of the following statements is TRUE according to the passage?
