【题目】The Internet of Things (IoT) aims to get everything and everyone talking. Attaching sensors to “things”, such as cows, cars and refrigerator, and then assigning them unique IP addresses allow them to “talk” to the Internet. Of course, the IoT will involve much more than a handful of sensors. Networking company Cisco estimates that 50 billion Internet-connected devices and objects will

be sending over data by 2020.

Specific Benefits
The IoT will allow people to track things and processes like never before. Airplane manufacturers will be able to continuously track the condition of airplane parts, allowing them to do preventive maintenance and avoid costly downtime. Consumers could install smart meters in their homes to monitor energy usage and observe energy price changes in real time. That would allow people to adjust their habits and use electrical appliances during lower-priced hours.

Some Fears
Some critics fear that the IoT could end up being a fashion that people lose interest in over time. Having Twitter feeds on refrigerator doors may sound cool at first, but the attraction could fade as quickly as the excitement over last year’s smartphone! Other critics are doubtful that companies making Internet-connected appliances will provide long-term software updates. If that happens, a refrigerator or washing machine that should last 10 years or more could last two or three due to software that’s outdated.

A Positive Example
Early this year, owners of the Tesla Model S electric car received a recall notice alerting them to a charger plug needing to be fixed. Amazingly, owners of the Model S sat back while the company performed an “over the air” wireless update. Customers confirmed the update by tapping on the car’s touchscreen console to see that the Model S was running the latest software version. No trip to the dealer was required!
Perhaps Tesla’s remote fix is a sign of things to come. Someday soon, people’s lives might become a lot more efficient and convenient thanks to the IoT.

【1】How do researchers get everything and everyone talking?

A. By establishing the IoT and launching a handful of sensors.

B. By connecting sensors with them and appointing them unique IP addresses.

C. By communicating with them all the time through the IoT.

D. By sending people to track them day and night and collect useful data.

【2】According to the article, which of the following is NOT TRUE?

A. IoT can help people do preventive maintenance and save money.

B. IoT can help people monitor energy usage and observe price changes timely.

C. IoT can help people adjust their habits and use electrical appliances more smartly.

D. IoT can help people investigate things and update a lot of important data.

【3】What else do critics worry about the IoT besides its probably ending up being a fashion?

A. People will lose interest in it as quickly as the thrill over last year’s smartphone.

B. Refrigerators and washing machines will be replaced by other devices in a few years.

C. Whether related companies will provide long-term software updates or not.

D. The software provided by companies will be outdated easily and quickly.

【4】According to the passage, when owners of the Tesla Model S electric received a recall notice, they ______.

A. just waited in the car while the maintenance is being done through wireless update

B. were required to go to the nearest 4s store to make some adjustments or repairs

C. could definitely depend on the IoT to send them the charger plug to be fixed

D. had to confirm the update with the help of the equipment provided by the company

【题目】Liz had been bleeding for a long time! She was my closest professional colleague and good friend at the time when we worked in an IT company. It was her first day back at work after an operation and I thought she should have taken a few more days to recover.

Realizing that we couldn’t stop the bleeding, we headed to the emergency room and spent hours there waiting to be seen. After the treatment, I drove her to my apartment. I had to leave her in my apartment while I dashed off to take a final exam for a very important course I was taking. Upon my return, we decided Liz was in a good enough condition to sustain a trip back from my Northern Virginia apartment to her home in Maryland.

Although it was nearly midnight and we were both exhausted, we still decided to set off. Unfortunately, in a not particularly safe part of town, we heard my car make a strange noise, and then ti was shaking violently as we drove along. Quickly, I stopped the car in the road and found a tire had blown out. Not knowing how to change a tire and feeling scared, I was trying out to figure out what to do next. Liz, weak from losing all that blood all day and weighing only about eighty pounds to begin with, came out and tried to help me. I had to scream at her to get back in the car and relax.

Within seconds, a taxi pulled up behind us. A huge man appeared and began walking toward us. I felt that the blood drained out of my face and I nearly fainted in fear.

“Got a flat tire, girls?” he asked.

“Yes,” I answered in a trembling voice.

In no time at all, the man changed the tire for us and rushed off back to his taxi. He refused any payment and did not even tell me his name. He would never know how badly we needed his services that particular evening. And I, with a grateful heart, will never forget his kindness.

【题目】 “The U．S.Food and Drug Administration(FDA)is considering to put stricter limits over tanning salons(晒黑廊)and wants to ban anyone younger than 18 years of age from using a tanning bed，”an advisory panel(专家团)announced last week.

The panel is calling for tighter controls on the industry such as requiring teenagers to get the approval from their parents before using tanning beds or limiting the use of artificial tanning to a certain age.“Given the absence of any demonstrated benefits，I think it is an obligation for us to ban artificial tanning for those under 18，”said panelist Dr.Michael Olding.

Along with a possible ban for teenagers，the panel also recommended that visible warning labels should be placed either on the tanning machines or in the salons in order to caution tanners of the possible dangers.In addition，the committee decided that stricter regulations and classifications were critical to make the machines safer.At this time the machines are categorized as FDA Class 1 devices，the ones that are least likely to cause harm.In case the FDA decided to change their classification from Class 1 to Class 2，as advised by the panel，the FDA could limit the levels of radiation the machines emit.Class 2 devices include Xray machines and powered wheelchairs.

Getting a tan，whether from a tanning bed or the sun，increases the risk of developing skin cancer.Last year，the World Health Organization's International Agency for Research on Cancer (IARC)declared tanning beds as “carcinogenic(致癌的)to humans”．It was discovered that young individuals in their teens and 20s who use tanning beds on a regular basis have a 75per cent higher risk of suffering from melanoma(黑素瘤)，the deadliest form of skin cancer.According to the American Cancer Society，melanoma accounted for nearly 69,000 cases of skin cancer in 2009 and will account for most (about 8,650)of the 11,590 mortality cases due to skin cancer each year.

【1】According to the passage，what measures will U．S.FDA most probably take?

A．Banning tanning salons.

B．Posing heavier tax over tanning salons.

C．Having tighter controls over tanning salons.

D．Limiting the number of tanning salons in every state.

【2】Which of the following suggestions for making tanning salons safer is NOT mentioned?

D．Parental approval for teenagers.

【3】What does the writer want to express in the last paragraph?

A．Tanning in one's youth may mean death.

B．Tanning in the sun is safer than on the tanning bed.

C．People should get tanned without getting melanoma.

D．Getting tanned is only a good idea for those above thirty years old.

【4】What will most probably happen，if the advisory panel's suggestions are adopted and put into practice?

A．Fewer people will suffer from skin cancer.

B．Tanning salons will have more customers.

C．Getting a tan in a tanning salon will cost less.
