Just finishing loading his car, my husband Jerry went back to the kitchen. “I guess filling my thermos (保温瓶) is all I have left to do,and then I’m off.” Down the drain (下水道) went the hot water that had been warming his thermos.

With a nostalgic (怀旧的) look on his face, he softly said: “Anytime I fill my thermos I think of your mom.” The tone in his voice was so tender as he spoke of my mother, who is sadly no longer with us.

“Oh, honey, I know she’s watching and listening right now with a big smile on her face,” I responded, tears in my eyes.

One morning years ago when we were leaving, mother watched as Jerry was to fill his thermos. Mom then casually said, “Jerry, if you filled your thermos with hot water and let it sit a while, your coffee would stay hot for longer then.” With her simple suggestion, his face showed that he was shocked by his own lack of common sense, well, of course it would! He poured out the small amount of coffee already in the thermos and refilled it with boiling hot water. Then he poured the water and refilled it with hot coffee. Mom smiled as Jerry did so.

Words of wisdom from a loving mother-in-law made an impact that will never be forgotten. She never dreamed her words would be a treasured and everlasting memory in the heart of her son-in-law.

The lasting memories don’t necessarily come from major moments in life. Memories are often made during those small, ordinary moments. Life is about small moments we share with friends and loved ones!

C．certainly and absolutely.	D．out of the question.

7. The message that the story intends to convey is ______.

D．why we should respect our parents and listen to them.

They already guide blind and disabled people; now dogs are to be trained to help people with dementia (痴呆) or Alzheimer’s. Alzheimer’s can make people confuse night and day or forget basic things such as washing or drinking enough water.

The dogs will be trained to respond to sound triggers (触发器) in the home that cause them to perform tasks. The duties will include reminding their owners to take medicine, as well as encouraging them to eat, drink and sleep regularly.

The idea was developed by design students at the Glasgow School of Art and will now be put into practice by Alzheimer’s Scotland and Dogs for the Disabled. The first dogs will be distributed to four Scottish couples, where one of the partners is in the early stages of dementia. Some 670,000 people in Britain have dementia and one in three over 65 will develop the condition. By 2021 this is expected to rise to one million.

Joyce Gray of Alzheime’s Scotland said, “People in the early stages of dementia are still able to live a relatively normal life, and dogs help to maintain routine.” Another advantage of using the pets as companions is that dogs can give them a sense of silent support and companionship. Ms Gray said, “The evidence is that people may forget familiar faces but not pets. It’s such a strong bond that people often remember them longest. People don’t need to communicate verbally (言语地) but they can still interact. You can have a speechless bond.

Helen McCain, director of Dogs for the Disabled, said, “People with dementia often forget to take the medicine. If a dog presents them with a bag with pills in it there’s a greater chance of them taking it. The dog would also encourage the owner to take them out for walks, ensuring they keep exercising and interacting with other people.”

8. In Britain people with dementia ______.

A．are likely to increase in number.

B．are mostly over 65 years old.

C．will be trained to respond to sound triggers.

D．will be able to live a relatively normal life.

9. The dogs are taught to perform tasks by ______.

A．making some sound signals.	B．communicating with the patients.
C．reminding the patients by barking.	D．reacting to some sound triggers.

10. What does the underlined word “them” in Paragraph 4 refer to?

A．Faces.

B．Triggers.

C．Pets.

D．Companion.

11. What is mainly talked about in the passage?

A．The idea of dementia dogs was developed by students.

B．Dogs are trained to assist Alzheimer’s patients.

C．British people with Alzheimer’s are in poor condition.

D．The dementia dogs perform most duties of a doctor.

While astronauts in space get to do many exciting things，they miss out on ordinary things that we all take for granted—being able to walk on firm ground，hanging out with family and digging into a slice of hot steaming pizza． Though not much can be done about the first two things，there may soon be a solution to the third one，thanks to this cool 3-D pizza printer！
About a year ago，NASA offered $125 ,000 to Anjan Contractor， a 3-D technology expert，to build a device（设备）that would allow astronauts to make pizza on demand． The mechanical engineer promised that his invention would produce pies in large quantities that looked， tasted and even smelled like pizza made in common ovens．
Late last year， the engineer presented a video of his first prototype（原型）that begins by creating a single slice of dough（面团）that is cooked and printed at the same time．Then comes the tomato “sauce” — a mix of tomato powder，oil and water and finally，a protein slice that resembles cheese．While the video doesn’t show the baking process，the inventor says that once the pizza is printed，it can be ready to be consumed in 7 seconds．
While the pie in the video looks delicious enough to attract any pizza lover，Anjan Contractor is far from ready for astronauts．That’s because he still has to find a solution to make the food container in the printer last for 30 years．Though that may sound unrealistic，actually it is not．
Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients（配料）and then they are reduced to the powder form．This，as you can imagine，will not be so easy．But，while the printer may not be ready for space，it certainly looks ready enough for people on earth．Hopefully，NASA and Contractor will consider selling it to those not fortunate enough to go to Mars！
12. Why does the author mention the things that astronauts in space cannot do？

A．To ask us not to take common things for granted．

B．To show they live a difficult life there．

C．To show their life is boring in space．

D．To introduce the topic of the text．

13. NASA offered $ 125，000 to Anjan Contractor mainly to _______．

A．create some new type of 3-D printer

B．attract more companies to work for NASA

C．help astronauts in space enjoy fresh pizza one day

D．produce pizza in large quantities to earn great profits

14. The biggest challenge that Anjan Contractor is faced with now is probably that _______．

A．he has no money left to go on with his research

B．the pizza doesn’t seem appetizing to pizza lovers

C．he has no way to make pizza that can last for thirty years

D．he cannot make the food container last for decades

15. What’s the best title of the passage？

A．NASA is trying its best to help astronauts eat better

B．Astronauts may soon be able to enjoy steaming hot pizza

C．NASA is working on making pizza for common people

D．A 3-D pizza printer has been used to make pizza
