Brook wanted a dollhouse and some sugar cookies. So the 6-year-old asked Alexa to get them. Alex, a vice-activated home assistant powered "by artificial intelligence"(Al), made Brooke's wishes come true. A few days later, much to her parents' surprise, four pounds of cookies and a $170 dollhouse showed up. And that's not the end of the story. When a news anchor told Book's story on TV, Alexa devices in many listeners' homes woke up and tried to order dollhouses!
Alexa isn't the only Al willing to order. Apple HomePod has Siri, Google Home has its Assistant, and the upcoming Galaxy Home device will have Bixby. People who own these devices use them mainly for listening to music, checking the weather and setting timers. But many experts predict a boom in voice shopping in the near future. Is that a good thing?
Convenience is the main benefit of voice shopping. You can shout out an order as soon as you think of it, even if you're cooking, cleaning, or driving. In addition, people with disabilities who are unable to use a keyboard or mouse can shop without assistance.
But voice shopping has its downsides. Unwanted dollhouses aren't the biggest problem. It's usually very easy to cancel an order or return items. The thing that creeps some people out is that these assistants are always listening. They have to be able to respond when you want them. So they listen for "Alexa" or "OK Google" or another command. When they hear it, they start recording the conversation. Some have worried about what happens to these recordings. Should companies be allowed to use them to learn about people's shopping habits? Should police access them to solve a crime? And what if someone hacks the device? The CIA found a way to hack smart TVs to turn them into spies that listen all the time. Others could do the same with any smart device.
1.The writer mentions Brook and Alex in the first paragraph to __________.
A.share an interesting experience B.show Brook's eagerness for cookies
C.introduce the topic of voice shopping D.show the functions of a new smart device
2.What does the underlined phrase "creeps... out" in the last paragraph most probably mean?
A.Terrifies. B.Affects.
C.Impresses. D.Excites.
3.According to the passage, what's the major disadvantage of voice shopping?
A.The return policy is complicated.
B.There are safety and privacy concerns.
C.Quality of the goods can't be guaranteed.
D.The device is not smart and reliable enough to process orders.

A cookie can give one person a sugar rush while barely affecting another person, a new study finds, indicating that a food’s glycemic index（血糖指数）is in the eater.
People’s blood sugar rises or falls differently even when they eat the exact same fruit, bread, deserts, pizza and many other foods, researchers report. That suggests that diets should be tailored to individuals’ personal characteristics.
The researchers made t
he discovery after fitting 800 people with blood glucose （血糖）monitors for a week. The people ate standard breakfasts supplied by the researchers. Although the volunteers all ate the same food, their blood glucose levels after eating those foods varied dramatically. Characteristics and behaviors such as body mass index, sleep, exercise, blood pressure, cholesterol levels and the kinds of microbes（微生物） living in people’s intestines are associated with blood glucose responses to food, the researchers conclude.Those findings indicate that blood sugar spikes （血糖尖峰）after eating depend not only on what you eat, but how your system processes that food.
A team led by a biologist created a computer algorithm(计算程序) that predicted how much a person’s blood sugar would rise or fall after eating a certain food. When testing on a new group of 100 people, the algorithm correctly predicted the response about 70 percent of the time.
A third group of 26 participants were then given personalized meals. The computer algorithm analyzed each person and then picked diets for 12 of them. A nutritionist chose a “good” and “bad” diet for the remaining participants. Good diets were ones that minimized blood sugar spikes after eating. Bad diets sent blood sugar skyrocketing. The diets contained the same amount of calories. It turned out that foods on the “good” diet for one person were sometimes on another participant’s “bad” list.
1.A food’s glycemic index depends on ______.
A. diets B. sleep
C. health D. eaters
2.Which of the following can best replace the underlined word “tailored” in Paragraph 2?
A. limited B. adjusted
C. applied D. compared
3.The good diets chosen by a nutritionist were the ones that _______ after eating.
A. made blood sugar unchanged
B. sent blood sugar rising sharply
C. reduced blood sugar spikes to the lowest
D. provided body with lots of calories
4.What can be a suitable title for the text?
A. People’s Blood Sugar Rises Or Falls
B. A Good Diet for You May be Bad for Me
C. Diets And Blood Sugar
D. Can a Cookie Give One Person a Sugar Rush?

Rich as a King
William 1, who conquered England some 930 years ago, had wealth, power and an army. Yet although William was very rich by the standard of his time, he had nothing like a flush toilet (抽水马桶), paper towels, or riding lawn mower (除草机). How did he get by?
History books are filled with wealthy people who were poor compared to me. I have storm windows, Croesus did not. Entire nations trembled before Alexander the Great, but he couldn’t buy cat food. Czar Nicholas lacked an electric saw.
Given how much better off I am than so many famous dead people, you’d think I’d be content. The trouble is that, like most people, I compare my wealth with that of living person: neighbors, school classmates, famous TV people. The greed I feel toward my friend Howard’s new kitchen is not reduced by the fact that no kings ever had a refrigerator with glass doors,
There is really no rising or falling standard of living. Over the centuries people simply find different things to feel sad about. You’d think that simply not having disease would put us in a good mood, but no we want a hot bath too.
Of course, one way to achieve happiness would be to realize that even by today’s standards the things I own are pretty nice. My house is smaller than the houses of many investment bankers, but even so it has a lot more rooms than my wife and I can keep clean.
Besides, to people looking back at our era from a century or two in the future, these bankers’ fancy counter tops and my awn worn Formica will seem equally shabby, I can’t keep up with my neighbors right now. But just wait.
1.What docs the underlined phrase “get by” in the first paragraph mean?
A. Succeed as a king.
B. Deal with complains.
C. Get some extra money.
D. Live in a satisfactory way.
2.How many historical figures are mentioned to compare lives in the past and present?
A. 3. B. 4.
C. 5. D. 6.
3.According to the passage, the author intends to .
A. tell us to be content with life
B. warn us to live in a simple way
C. leach us to learn lessons from life
D. encourage us lo struggle for wealth
4.What’s the author’s attitude towards life?
A. Doubtful. B. Optimistic.
C. Uncaring. D. Cautions.
