The Beagle Brigade

When returning to the United States from a trip abroad, passengers will have their baggage inspected at U.S. airports by the U.S. Department of Agriculture’s Beagle Brigade, a team of beagles and their human partners. Working with their human partners, the beagles search for agricultural products carrying diseases and pests which are likely to infect American agriculture.

An orange or apple, for example, might harbor a Mediterranean fruit fly. Ham could carry a disease such as cholera. These and other pests could do harm to farmers’ crops. “Once we introduce something that is not part of the environment, there may not be any controls for it in the environment,” notes USDA’s Lisa Davis at the National Dog Detector Training Center in Orlando, Florida. “The best thing for us to do is to prevent it from coming across the border and spreading.”

When a beagle smells food smells, it signals its partner by sitting there. The human partners then investigate. When the dog is right--which happens 90 percent of the time—it gets something to eat.

“The dog is not out there working,” explains Davis. “It’s out there playing. It’s a game to the dog.” The partners give the beagles plenty of food and loving. They make sure they get first-class medical attention, too. When the dogs finally retire after 9 to 11 years, the USDA finds caring homes for them. It’s a dog’s life indeed!

Their people partners work and study somewhat harder. As specialized quarantine(檢疫) officers, most hold degrees in the biological sciences or related sciences.

How well does the Beagle Brigade do its job? “On the average,” notes Davis, “each year our 54 teams prevent around 75,000, restricted(限制的) items.” Since even one infected item could cause widespread destruction, that’s a great result for America’s agricultural environment.

You use her as a shoulder to cry on. She texts you back with casual jokes. But she, Xiaoice, is only a virtual chatbot.

Xiaoice, Microsoft's latest artificial intelligence robot, was briefly released in 2014, and returnen to WeChat in 2015, where she became a big hit. Millions of young Chinese now exchange messages with her daily, The New York Times reported. On WeChat, Xiaoice is an official account. After following it, users can start text-based conversations with Xiaoice.

"Her incredible learning ability was why people loved to talk with Xiaoice," Liu Jinchang, a researcher at High-tech Research and Development Center under the Ministry of Science and Technology, told China Daily. Apart from her ability to identify photos and send emojis(表情符號(hào))m conversations, Xiaoice gains 45 percent of her knowledge from interacting with users, China Daily reported.

Chatbot programs first appeared in the mid-1960s in the US. Driven by top tech companies, they are becoming smarter and more common. For instance, IBM's latest artificial intelligence program served as an academic consultant at Australia's Deakin University, answering students' questions about course schedules and financial aid. Apple's Siri and Amazon's Alexa have been used as voice assistants who can read news, play music and even make jokes for their users.

These programs are expected to move beyond smartphones, into televisions, cars and living rooms, The New York Times pointed out. However, it may take decades before scientists develop a "Samantha", the advanced chatbot seen in the fiction film Her. In the film, Samantha sparks a romantic relationship with her user played by US actor Joaquin Phoenix. Many viewers were enthusiastic about this fan tasy of virtual soul mates.

1.What does the underlined part in paragraph two mean?

A. She became a best seller.

B. She became very powerful.

C. She became a money maker.

D. She became very popular.

2.Which of the following can Xiaoice do?

A. Do housework.

B. Spread messages.

C. Identify various photos.

D. Read news to its users.

3.Which company's chatbot program can act as an academic consultant?

A. Microsoft. B. IBM. C. Apple. D. Amazon.

4.What can be learned from the last paragraph?

A. Chatbots mainly run on smartphones now.

B. It'll take decades to apply chatbots to cars.

C. Samantha is played by a US actor in the film.

D. The film Her doesn't interest many audience.

Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of diet plan.

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(難為情)when they’ re in poorly lit places----and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.

Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it’s time to repaint, go blue.

Don’ t forget the clock----or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’ re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one ,total intake (攝入) jumps by 14 percent. And we’ ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

1.The text is especially helpful for those who care about_______.

A. healthy diets B. house buying

C. their body shape D. their home comforts

2.A home environment in blue can help people_________.

A. reduce food intake B. digest food better

C. regain their appetites D. burn more calories

3.What are people advised to do at mealtimes?

A. Use smaller spoons. B. Turn down the lights.

C. Eat quickly. D. Play fast music.

4.What can be a suitable title for the text?

A. Is Your Home Environment Relaxing?

B. Is Your House Making You Fat?

C. Ways of Serving Dinner

D. Effects of Self-Consciousness
