If you are in Dubai you may notice a robot police officer sharing the street with you. Your first thought might be, “Have I walked into a movie set？”

The answer is no. That robot is Dubai's newest police officer. The robot has a touch screen instead of a gun. The robot will be employed mostly at shopping centers and other places popular with visitors.

The robot's face has eyes but no mouth or nose. It stands 165 centimeters tall and weighs 100 kilograms. If the robot works well, Dubai says 25 percent of its police force could be robots by 2030. The robot cop(巡警) was officially presented at Dubai's Gulf Information and Security Expo and Conference in May.

The police hope the robot will make life easier for the people of Dubai. Khalid Al Razooqi is Director General of Smart Services at the Dubai Police. He said the robot can help the public every day, and that “it won't ask for any sick leave”.

The robot cannot make arrests (逮捕). But it can recognize faces and compare them to photographs on a criminal database. It can also sense emotions. People can use the robot's touch screen to do things like reporting a crime, paying fines and reporting lost or found things. They can also ask how to get somewhere. The robot can greet and shake hands with people. So far, the robot can speak Arabic and English. It soon will learn other languages such as Russian, Chinese, French and Spanish. In addition to having a touch screen, the robot has a camera that can live stream video to a police command center.

Dubai has plans to add other kinds of robots to its police force. Within two years, the city plans to use a three­meter­tall robot that can run up to 80 kilometers an hour. The Dubai government says the machine would be the world's largest robot. A human police officer will be able to sit inside and control the robot. It will be able to lift heavy objects.

The city also plans to use an egg­shaped robot to control parking areas and give tickets to people who break traffic laws.

1.Why do the police use the robot?

A. To attract more tourists to Dubai.　　 B. To make people's life much easier.

C. To reduce the cost of the human workforce.　　 D. To introduce new technology to people.

2.According to the Paragraph 5, the robot cannot be used to ________.

A. report a crime　　 B. pay fines

C. ask for directions　　 D. chat with people freely

3.What can be inferred from the text?

WHEN you buy cooking oil in the supermarket, you may notice that some brands are labeled as “GM (genetically modified)-free”. So, what is genetic modification? Are GM foods safe?

These questions have been put back into the spotlight recently. On Nov 19, the Food and Drug Administration (FDA) in the US announced that it had approved the AquAdvantage salmon (三文鱼) to go on the market, making it the first genetically modified animal to be approved as food anywhere in the world.

GM foods are plants or animals that have been given a gene from another plant or animal to make them stronger in some way. The AquAdvantage salmon contains a gene from another type of salmon that makes it grow faster.

Although the FDA has said “food from the fish is safe to eat”, some believe that scientists can’t completely understand the potential health risks of GM foods, simply because they’re so new. Others worry that the fish could escape into the wild and cause ecological (生态的) problems.

GM crops have experienced the same controversy, even though GM technology cuts down on the use of pesticides (杀虫剂) on crops and increases yields.

While GM animals are new, GM crops have already appeared on our plates. A total of 28 countries in the world including the US, Brazil and India planted 181.5 million hectares (1.815 million km2) of GM crops in 2014, according to the International Service for the Acquisition of Agri-biotech Applications. In China, we grow GM cotton and papaya (木瓜) and import GM soybeans, corn, rape (油菜), cotton and beets (甜菜) from abroad.

Due to safety worries, many countries have regulations for producing and selling GM food.

In European Union countries, each GM food must be approved before it can be used. This process can take up to 17 months. The origin of all GM foods must also be traceable (可追溯的) , and all food with a GM content of more than 0.9 percent must also be labeled, according to EU website europa.eu.

The US is less strict about GM foods. According to FDA regulations, companies introducing new GM foods to the market should report them at least 120 days before release. The labeling is voluntary (自愿的), except that a product cannot be labeled as “GM-free” if genetically modified materials are used.

In China, GM foods can only be produced after strict tests by the Ministry of Agriculture say that they are safe. All food that is made from GM crops or contains GM ingredients must be clearly labeled on the wrapper (包装).

1.According to the text, the AquAdvantage salmon ______.

A. tastes better than normal salmon

B. is a product that mixes several types of fish

C. has a gene from a different type of salmon

D. remains to be approved in several countries

2.One of the reasons for many people to worry about the AquAdvantage salmon is that ______.

A. the gene that makes them grow faster can work on humans too

B. there are possible health risks that even scientists might not have figured out yet

C. they could possibly become threats to other wild species

D. they are not nutritious enough or might taste strange

3.From the text, it can be concluded that GM crops _____.

A. no longer cause any controversy

B. have already been planted in some countries

C. are popular because they don’t need pesticides

D. can increase yields, making them welcome in countries like Japan

4.Which of the following is TRUE about regulations for producing and selling GM food?

A. All food with GM content must be labeled in European countries.

B. In the US, the AquAdvantage salmon will have to be labeled as GM food.

C. In France, every GM food that is about to go on the market must be reported at least 120 days before release.

D. In China, all food that is made from GM crops or contains GM ingredients must be clearly labeled on the package.

Are you preparing for a big test? If so, you may want to go to play some basketball in between hitting the books. Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels (血管), including those in the brain, stronger and more fully developed. Dr. Cameron is sure that this allows people who exercise to think better. As she says, “While we already know that exercise is good for the heart, exercise can actually cause physical changes in the brain.”

The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement show greater brain development than babies who are less physically active. Even a little movement can show big results. Margaret Barnes, a scientist, also believes in the importance of exercise. She thinks that many learning disabilities that children have in primary school or high school can result from a lack of movement as babies. Babies need movement that encourages and excites their five senses. They need to set up a connection between motion and memory. In this way, as they get older, children will begin to connect physical activity with higher learning,” says Margaret.

Older people can develop their brains as well. Cornell University studied a group of seniors who have a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for babies, exercise for older people should not be too simple. Learning some new skills or actions, such as with yoga or tat- chi helps to open up memory paths in the brain that may not have been used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main aim is to increase the brain’s flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.

1.What is the main idea of this passage?

A. How exercise makes people strong.

B. How to get good scores in a test.

C. How exercise helps the brain develop.

D. How the brain can change one’s memory.

2.According to the passage, what is the connection between exercise and brain development?

A. Exercise helps soften our blood vessels.

B. Physical exercise helps us think better.

C. The brain needs special mental exercise.

D. The more exercise, the bigger the brain.

3.For ordinary people, the smallest amount of exercise required to gain any benefit is ______.

A. two hours per week　　 B. 40 hours per week

C. three hours per day　　 D. 40 hours per month

4.Why is yoga suggested for seniors?

A. It does good to the joints of old people.

B. It does not increase the heart rate.

C. It includes learning new actions.

D. It can be done in groups.
