The Mona Lisa effect describes the phenomenon where the eyes in a portrait seem to follow the person looking at it, no matter where the person stands in the room. The effect was obviously named after Leonardo da Vinci s famous painting featuring the woman with the mysterious smile and the steady stare. But ironically (讽刺地), a new study/ finds that Mona Lisa may not be all that interested in tracking her observers. Two researchers from Bielefeld University in Germany found that the famous subject of the painting, also known, as "La Gioconda"，is actually looking just over your right shoulder.

For the experiment , Horstmann and his research assistant Sebastian Loth gathered two dozen participants to take a look at the eyes of the painting. But they didn't just ask them if they thought Mona Lisa was looking their way.Instead they displayed part of her face on a computer screen, then asked volunteers to measure her stare using a carpenter's ruler that was held horizontally between them and the screen.

Although the computer screen and the participants stayed in the same spot, the ruler was moved closer and farther from the screen during the trial. In addition, the researchers modified the size of Mona Lisa 's face and how much of her features were visible to see if that changed the perception of her stare. I he images showed varying degrees of rise一from 30 to70 percent with some showing her entire face and others showing just her eyes and nose.

The researchers also moved the images several centimeters to the left and to the right, so the Participants wouldn’t just pick the same measurement on the ruler each time.

Horstmann and Loth published their results in the journal i-perception where they were very clear in their conclusion.“We conclude from the measurements that the; lack of evidences due to the declaration being objectively false: Mona Lisa does not stare at the viewer ,” they wrote.“There is no doubt about the existence of the Mona Lisa effect---it just does not occurwith Mona Lisa herself.

28. What does the new study find?

A. The Mona Lisa effect does exist.

B. The reason for Mona Lisa smile.

C. What is the origin of the real Mona Lisa.

D. Mona Lisa is not Straightly looking at the viewer.

29. What were the participants required to do during the experiment?

A. To operate a computer as they moved.

B. To measure the direction of the stare with a ruler.

C. To count the direction of the stare with a computer.

D. To evaluate the distance between each participant.

30. Which can best replace the underlined word“"modified” in paragraph 3?

A. Estimated.   B. Changed.

C. Enlarged.    D. Described.

31. What do Horstmann and Loth think of the new finding?

A. It's reasonable and clear.

B. It's beyond expectation.

C. It's short of solid evidence.

D. It's consistent with previous studies.

D

We have all been there. In a rush to leave the house we grab ou phone6 a head out of the door, realizing all too late that the battery is dead because we forgot 1oprog it into the table cloth. Or perhaps we have not. But this could be be future that scientists hope to explore with eletr6nic sheets that charge our Mobile phones, laptops and other equipment by harvesting energy from the world around us.

In a step in that direction, scientists at Massachusetts Institute of Technology ( MIT)have created super- thin，bendy materials that absorb wireless Internet and other electromagnetic waves in the air and turn them into electricity. The lead researcher, Tomas Palacios, said the breakthrough smoothed the way for energy- harvesting covers ranging from table cloths to giant packing for buildings that catch energy from the environment to power sensors and other electronics.

Palacios and his colleagues connected a bendy antenna(天线)to a flexible semiconductor(半导体)layer only three atoms thick. The antenna picks up wifi and other radio frequency signals and turns them into a current. This flows into a special semiconductor, where it is changed into a direct electrical current. Researchers have made energy-harvesting“rectennas ( rectifying antenna )”before,but existing equipment is made from conventional semiconductors which are inflexible, fragile and practically impossible to make in large sheets.

The wi-fi signals can fill an office with more than 100 microwatts of power that is ripe to be collected by energy-harvesting equipment. The MIT system has an efficiency (效率) of between 30% and 40%，producing about 40 microwatts when exposed to signals bearing 150microwatts of power in laboratory tests.“It doesn't. sound like much compared with the 60watts that a computer needs, but you can still do a lot with it,” Palacios said. “ You can design a wide range of sensors, for environmental monitoring or chemical and biological sensing, which operate at the single microwatt level.”

Medical equipment is another potential application. Because wi-fi and similar radio-frequency signals pass through people, energy-harvesting covers could be applied to implanted sensors to provide them with enough power to send out health data to an outside receiver.

32. What does the underlined word “it” in paragraph 1 refer to?

A. The phone   B. The door.

C. The sheet    .D. The table.

33. What is special about the new breakthrough?

A. It can harvest wi-fi energy.

B. It is super thin and flexible.

C It can power all the electronics

D. It smooths the way of receiving signals

34. What can be inferred from paragraph 4?

A The team will focus on improving efficiency of the new equipment.

B. A single device can harvest half of the energy in an office.

C. Palacios is pleased with the fie of the new。equipment.

D. Palacios will step into the field of chemistry.

35. What is the main idea of the last paragraph?

A. Another energy harvesting equipment.

B. The function of the health data receiver

C. Another potential application of the new equipment.

D. The way to implant the new equipment into the patient.

第二节(共5小题:每小题2分，满分10分)

相据短文内疼，必演文后的选项中选出能填人空白处的最佳选项，选现中有两项为多余选项。

While it may be difficult t0 find the time in a busy workday to try and eat healthily and stay on top of fitness goals, there are several simple ways you can help fight off belly(腹部)fat while at work:

●Avoid free food at work: A study found that 23 percent of working Americans eat food a work gt least once a week, which leads to an increase of 1,292 calories on average per Week.36______.That way you know exactly what you are eating and what ingredients (材料) you used to prepare the meal. You can better control your calorie intake, too.

●37_____ : Burst training at the office, defined as 30 to 60 seconds of all-out high-intensity exercise followed by one to two minutes of lower-intensity recovery, is one of the best ways to fight belly fat on the job. Try simple short burst exercises like a 60-second round of jumping jacks or running in place._ 38 ， they are great places to perform burst training and get some fresh air, which is vital for mental health,

●Never skip breakfast: Eating breakfast is a characteristic common to successful weight-loss people and may be a factor in their success.39_____  ，chances are solid that no weight-loss professional would ever encourage someone to skip breakfast.

●Drink water throughout the day: A study concluded that drinking water may promote weight loss in overweight dieting women. In addition to helping ward off belly fat, staying hydrated may prevent energy crashes and loss of mental focus.

Perhaps one of the most critical pieces of belly-fat fighting advice: Don't go more thanfour hours without eating._ 40_____ . That's no good.

A. Keep doing regular exercise

B. If you work near parks or hills

C. Do several rounds of“burst exercise" each day

D. When you eat something between lunch and dinner

E. Though here is some debate about eating breakfast

F. The best solution is to bring your own homemade lunch

G. Some people go six or more hours during the day without eating
