The home humidity (湿度) is a measurement of the amount of vaporized (汽化了的) water in the air of the home. Humidity levels are naturally higher in warmer climates and lower in cooler climates. 1.Older and less energy efficient homes tend to have lower indoor humidity levels, while modern homes with higher energy efficiency tend to have higher humidity levels.

Both high and low home humidity levels can cause problems. Humidity levels that are too high can affect paint and cause mold (霉菌) . Humidity levels that are too low can cause cracks in your drywall and affect furniture. 2.

You may wonder what exact level of humidity you should have. Generally, people are most comfortable when home humidity is between 20 and 60 percent. 3. It can balance your need for comfort with the conditions that are less likely to damage your house.

4. It doesn't require expensive equipment. Just drop three ice cubes into a glass, add water, shake it and wait for three minutes ;　 if moisture(水汽) does not form on the outside of the glass, you may need to increase humidity. On the other hand, if you notice frequent fogging of your windows, you may have too much humidity in your home.

Daily activities like cooking can add water to the air in your home. If the home humidity level is top high, you can start cooking with pans covered. 5. If these basic changes don't help correct the problem, use a dehumidifier.

A. This is the ideal humidity level.

B. You must add water on a regular basis.

C. High humidity levels can damage furniture.

D. So do avoid too high and also too low humidity levels.

E. Taking shorter showers may also control the humidity.

F. Home humidity levels can be measured in simple ways.

G. The type of home can also affect the humidity measurements.

The place of exposure to the greatest amount of allergen（过敏原）for the longest time is in the bedroom. Up to 60% of the dust mites（螨虫）found in the home are actually living in your bed and you spend about one-third of your life in the bedroom! And, bedrooms are the easiest area to control as an allergen free zone. Your cleaning professional will first vacuum the mattress（垫子）, carpeting and furniture using a vacuum cleaner.

The mattress is then thoroughly cleaned on all surfaces using the Responsible Care cleaning agents and a special low moisture cleaning tool designed to leave the mattress as dry as possible. Following cleaning, Allergy Relief Treatment is applied to all mattress surfaces using a fine mist application. The mattress is then placed in a drying position and a special air mover used to speed the drying process, which, depending upon temperature and humidity, normally takes about an hour.

The same safe cleaning agents are used to clean the bedroom carpeting and if desired, any furniture or rugs. This is also followed by an application of Allergy Relief Treatment. Once again, a speed drying system is set up to dry the cleaned items as quickly as possible and bring the humidity down to normal levels. Baseboards and windowsills are cleaned as well. While the cleaning and treatment service is being performed it is highly recommended that the bedding and pillows be washed in hot water and that two cups of Allergy Relief Treatment be added to the washing cycle.

While servicing the bedroom is the highest priority（优先）, significant benefits may also result from cleaning and treating other areas where allergy sufferers spend lots of time. These areas include the furniture and carpeting in rooms where time is spent watching television, reading and so on. Also, carpeted areas that pets have access to should be cleaned and treated.

A test for the presence of dust mites in quantities requiring treatment is also available from our company. But we will only test dust mites and will not provide information on pet allergen.

1.Which place has the most dust mites in your room?

A.Bed. B.Carpet.

C.Furniture. D.Floor.

2.What is mainly talked about in paragraph 2?

A.The use of cleaning agents.

B.The surfaces of mattress.

C.Cleaning the mattress.

D.Drying the mattress.

3.What do we know about Allergy Relief Treatment mentioned in this passage?

A.It is a cure to allergy.

B.It is a tool to kill mites.

C.It is the name of a company.

D.It is a chemical to prevent allergy.

4.Where might this passage come from?

A.A magazine about furniture.

B.The website of a cleaning company.

C.The website of a hospital.

D.A newspaper on public health.

2.　 　　 .

If there’s any big truth about life, it's that it usually lives up to your expectations. Therefore, when you rise from bed, make your first thought: “Something wonderful is going to happen today.” Guess what? You're probably right.

Take time to plan and prioritize(优先处理)

The most common source of stress is the thought that you've got too much work to do. Rather than worry about it, pick one thing that will move you closer to your highest goal and purpose in life. Then do that first.

Eat high quality food slowly

3.　 　　 . Even so, at least once a day try to eat something really delicious, like a small chunk of fine cheese or an imported chocolate. Taste it, focus on it and enjoy it.

Let go of your results

The big enemy of happiness is worry, which comes from focusing on events that are outside your control. Once you've taken action, there's usually nothing more you can do. 4.　 　　 .

End each day with gratitude

Just before you go to bed, write down at least one wonderful thing that happened. It might be something as small as making a child laugh or something as huge as a million dollar deal. 5.　 　　 　 .

A. Start each day with expectations.

B. Give a gift to everyone you meet.

The idea that computers have some amount of “intelligence” is not new, says Ralph Haupter, the president of Microsoft Asia, pointing as far back as 1950 when computer pioneer Alan Turing asked whether machines can think. “So it has taken nearly 70 years for the right combination of factors to come together to move AI from concept to reality,” says Haupter.

It is predicted that the development of artificial intelligence will be the story of the coming generations, not just the coming year, but as 2019 gets underway, you’ll find AI will begin to touch your life in many ways according to some researchers.

“Personal assistant AIs will keep getting smarter. As our personal assistants learn more about our daily routines, I can imagine the day I need not to worry about preparing dinner. My AI knows what I like to eat, which days of the week I like to cook at home, and makes sure that when I get back from work all my groceries are waiting at my doorstep, ready for me to prepare that delicious meal I had been longing for.” ---Alecjandro Troccoli, senior research scientist, NVIDIA.

“Thanks to AI, the face will be the new credit card, the new driver’s license and the new barcode (条形码). Facial recognition is already completely transforming security with biometric capabilities being adopted, and seeing how technology and business are connected, like Amazon is with Whole Foods, I can see a near future where people will no longer need to stand in line at the store.” ---Georges Nahon, president, Orange Institute, a global research laboratory.

“2019 will be the year AI becomes real for medicine. By the end of the year we’re seeing solutions for population health, hospital operations and a broad set of clinical specialties quickly follow behind.” ---Mark Michalski, executive director, Massachusetts General Hospital.

1.What can we know about AI from the first two paragraphs?

A.People didn't expect AI to develop so rapidly.

B.The idea of AI just came up recently.

C.The concept of AI was put forward by Ralph Haupter.

D.It took more than 70 years to turn the concept into reality.

2.Who sees the future of AI doing housework instead of human being?

A.Alan Turing. B.Georges Nahon. C.Mark Michalski. D.Alejandro Troccoli.

3.What is Georges Nahon’s job?

A.Executive director of a hospital. B.President of a research laboratory.

C.Chairman of an energy corporation. D.Chief operating officer of a newspaper.

4.How is the passage developed?

A.By explaining cause and effect. B.By presenting research results.

C.By listing some predictions. D.By describing personal experiences.

Success is often measured by the ability to overcome adversity. But, it is often the belief of others that gives us the courage to try.

J. K. Rowling, author of the Harry Potter book series, began writing at age 6. In her biography, she remembers with great fondness when her good friend, Sean, whom she met in secondary school, became the first person to encourage her and help build the confidence that one day she would be a very good writer.

“He was the first person with whom I really discussed my serious ambition to be a writer. He was also the only person who thought I was bound to be a success at it, which meant much more to me than I ever told him at the time.”

Despite many setbacks Rowling persevered in her writing, particularly fantasy stories. But it wasn't until l990 that she first conceived the idea about Harry Potter. As she recalls, it was on a long train journey from London to Manchester that “the idea of Harry Potter simply fell into my head. To my immense frustration(沮丧), I didn't have a functioning pen with me, and I was too shy to ask anybody if I could borrow one. I think, now, that this was probably a good thing, because I simply sat and thought, for four(delayed train) hours, and all the details bubbled up in my brain, and this scrawny, black-haired, bespectacled boy who didn't know he was a wizard became more and more real to me.”

That same year, her mother passed away after a ten-year battle with multiple sclerosis, which deeply affected her writing. She went on to marry and had a daughter, but separated from her husband shortly afterwards.

During this time, Rowling was diagnosed with clinical depression. Unemployed, she completed her first novel in area cafes, where she could get her daughter to fall asleep. After being rejected by l2 publishing houses, the first Harry Potter novel was sold to a small British publishing house.

Now with seven books that have sold nearly 400 million copies in 64 languages, J. K. Rowling is the highest earning novelist in history. And it all began with her commitment to writing that was fostered by the confidence of a friend !

1.Who believed J. K. Rowling was to be a good writer?

A．Her friend Sean.    B．Her mother.        C．Her daughter.      D．Her husband.

2.Rowling first came up with the idea about Harry Potter ________.

A．at the age of 6                          B．on a train journey

C．after her mother's death                  D．in her secondary school

3.She felt frustrated on the train because ________.

A．her train was delayed for four hours

B．she didn't have a pen with her

C．her mind suddenly went blank

D．no one would offer her help

4.It can be concluded from Paragraph 5 and 6 that Rowling is ________.

A．open-minded      B．warm-hearted      C．good-natured      D．strong-willed

5.The text mainly tells us ________.

A．hardship makes a good novelist
