I didnt check my schedule before I said yes. Id seen these insects light up the forests in

9、Tlaxcala once before, and I jumped at the chance to go back.While studying, I began exploring Mexico, crossing the country several times by bus. Now I work as a photojournalist in Mexico and along the border, documenting desperate situations that face everyday Mexicans. Though necessary and importan

10、t, news stories dont reflect the Mexico that I fell for and that is home to so many people I love. A task focused on the countrys natural beauty was a welcome reprieve for me.I had three nights to film the magical scene in the forest. According to our guides, visitors are usually not allowed to phot

11、ograph the fireflies because the presence of artificial light from electronics can affect their habits. As I started shooting, I adjusted my exposures constantly to account for the fading light. In order to get the composition that I wanted, I placed my tripod (三脚架) on a steep, rocky path and had to

12、 steady it during the long exposures. Normally this wouldnt be a big deal, but the fireflies were very interested in the camera and, by extension, in me. I stood completely still while they were all over me-my arms, my hair, my face. From what I observed, peak (高峰时期的) firefly presence lasts for only

13、 about 20 minutes each night, so I had time for just a few tries.On the last night everything came together. The weather cooperated. I had improved my method for focusing and composing photos in the dark with quick flashes from a powerful flashlightand Id grown accustomed to insects on my face.I was

14、 rewarded with the image you see here. Each dot of light is one of several bursts that a firefly makes as it travels within a 30- second exposure. You can track the insects paths: Some make small circles, like those in the bottom center of the frame, while others move steadily in one direction or an

17、thors working conditions.Many people, especially the elderly, suffer from abnormal sleep. In particular, the deep sleep phases become shorter and shallower with age.Researchers have shown that the brain waves characterizing deep sleep, so-called slow waves, can be improved by playing precisely timed

18、 sounds through earphones while sleeping. While this works well in the laboratory under controlled conditions, there has been no at-home solution that can be used for a time longer than just one night.As part of the SleepLoop project, researchers have developed a mobile system that can be used at ho

19、me and aims to promote deep sleep through auditory(听觉的) brain stimulation.The SleepLoop system consists of a headband that is put on at bedtime and worn throughout the night. This headband contains electrodes(电极) and a microchip that can constantly measure the brain activity of the sleeping person.

20、As soon as the sleeping person shows slow waves in the brain activity, the system will set off a short auditory signal. This helps synchronize(使同步) the neuronal cells and enhance the slow waves. What makes the solution unique is that the sleeping person is not consciously aware of this sound during

21、deep sleep.Its the first time that the researchers, led by Caroline Lustenberger, have conducted a clinical study with this device. The study involved equipping participants, between 60 and 80 years old, with the SleepLoop system, which they were required to operate in their own homes. The system is

22、 designed to function independently even for users with little technical experience. “This worked very well. We had surprisingly little data loss and the participants rated the device as user-friendly,” says Lustenberger.The participants wore the device every night for a total of four weeks. The res

23、ults showed it was indeed possible to enhance the slow waves through auditory signals during deep sleep in most participants. However, individual differences were considerable, which can be used to better predict how a given individual will respond to the auditory stimulus. The company ToSoo AG is c

24、urrently working on that so that it can be competitive once it comes onto the clinical market. Its already clear that itll not be freely available, but only via a doctors prescription. “Use of the device must be medically indicated,” a researcher says.8What did researchers of the SleepLoop project t

28、e.DGetting medical officials permission.Massive heat waves and droughts are already becoming a threat to farmers. Over the next three decades, Californias San Joaquin Valley alone could lose up to 535,000 acres of farmland as a result of the shortage of water supplies.Jennifer Brophy, an assistant p

29、rofessor of bioengineering at Stanford, is working on methods she hopes will be used to change commercial plant species so they can survive severe conditions. She is developing new genetic engineering techniques that can help plants grow in a variety of different conditions. By changing the genome (

30、基因组) of both commercial crops and soil bacteria, she thinks it may be possible to help plants survive droughts.To make plants respond to extreme climate, Brophy is building what she calls “genetic circuits (基因回路).” In addition to changing the genes within plant cells, this method also changes how an

31、d when those genes are activated (激活). If the plant senses a specific sugar, it can express one protein; if it senses another signal, itll express a different protein, kicking off an entirely separate chain of events. If both signals are there, the plant may be able to express something else entirel

32、y. “Using circuits, you can have plants respond in new ways to all these different inputs,” she says.Humans can learn from the weather forecast whether its going to be really hot or really dry in the next couple of weeks so that we can plan accordingly. “A plant doesnt necessarily know whats coming.

33、 It just knows if its hot or mild right now,” says Brophy. This can lead to problems when weather becomes unstable. A plant that usually flowers in spring may flower in winter if there are a few unseasonably warm days. When temperatures fall again, the flowers die and ruin a year of crops. “Itd be g

34、reat to be able to communicate with plants to tell them, hey, you should wait on that flowering,” she adds.Controlling plants growth at this level is an exciting prospect, but actually putting it into practice is along way off. At the moment, Brophy is testing the concept in the lab using a small we

38、hat walking among trees makes us relaxed. 16 Theres plenty of research showing the link between being in nature and being happy, but most of the research has focused on adults. 17 Explaining the motivation behind the study, researchers note that with environmental issues such as global warming, more

39、 studies are focusing on the relationships between humans and nature to find solutions to these problems, and the future of the planet lies in the hands of children and their actions. However, few studies focus on this aspect. For the study, researchers worked with 296 children between the ages of 9

40、 and 12. To measure how connected they were to nature, the kids were asked how much they enjoy activities like seeing wildflowers and wild animals, hearing sounds of nature and touching animals and plants. 18 They also found that the more concerned children were about the environment and nature, the

41、 more likely they were to be happy.So exposure to nature is related to active behaviors and happiness of children. What does that mean to adults? As we all know, children usually tend to follow adults, especially their parents behaviors. Thats to say, when adults are outside and appreciate nature, k

42、ids learn by example. 19 Researchers say that children need role models who can gently guide them to nature with excitement and an attitude of a lifelong learner. 20 Whats more important is that they spend time together with children by exploring a fun and safe environment.AIts so good going for a w

43、alk around trees.BEven just smelling the trees helps reduce anxiety.CAnd if parents enjoy being close to nature, so will their children.DParents dont have to be experts in environmental science or nature studies.EThey found that the kids connected to nature were more likely to behave actively.FIn a

44、new study researchers wanted to see if kids get the same benefits from being outdoors.GResearchers will study more about the connection between childrens happiness and nature.二、完形填空With the start of new school, most freshmen were excited to meet new classmates and teachers. 21 , 15-year-old Sergio P
