              Thousands of years ago, it was common to see many stars in the sky.   (1)   , this changed with the invention of   (2)   . Cities have gone brighter, using more lights. And that means most people in urban areas will never see beautiful groups of stars. They will never see a   (3)   night sky and never be inspired by it.

              Today, people are   (4)   by light — even at night time. Much of this light   (5)  where it shouldnˈt be — it creates light   (6)   . For example, a person can put a light outside to shine on his own house. But the light could be so strong that it may   (7)   shine on his neighborˈs house. The   (8)   light shining on the neighborˈs house is one kind of light pollution.

              But is all this light really a big   (9)   ? People need light to see, work and drive safely at night, and for many other things! But scientists say that this extra light has proven   (10)   on living creatures — animals and humans.

              One kind of animal   (11)   by light pollution is the bird. Many birds travel to a different area of the world to lay eggs,   (12)  at night. But lights from tall buildings can   (13)   the birds off their natural path. They may also crash into brightly lighted buildings, in danger of losing their   (14)  .

              Human beings experience problems   (15)   light pollution too. Light affects some chemicals in peopleˈs bodies. And people who are continually   (16)  to light at night have higher rates of health problems.

              People and animals need light,   (17)   they also need darkness. Experts say that people must use light   (18)   . Only use the amount of light that you   (19)   . Donˈt think that more light is better light. People also can greatly   (20)   light pollution by using well-designed lights, which only shine light where it should be. Using less light and better lighting decisions reduces the energy people use.

              Most people are poor listeners. Even when we think we are listening carefully, we usually   (1)   only half of what we hear, and we remember even less. Improving your listening skills can be   (2)   in every part of your life.

              The most important   (3)   of poor listening is giving in to distractions (分心的事物) and letting our thoughts   (4)   . Sometimes, however, we listen too   (5)   . We try to remember every word a speaker says, and we lose the   (6)   message by concentrating on details. In other situations, we may jump to conclusions and   (7)   a speaker without hearing out the message. Finally, we often judge people by their   (8)   or speaking manner   (9)   listening to what they say.

              You can   (10)   these poor listening habits by taking several steps. First, take listening   (11)  and commit yourself to becoming a better listener. Second, work at being a(n)   (12)  listener. Give your undivided attention to the speaker in a genuine effort to   (13)  her or his ideas. Third,   (14)   distractions. Make a conscious effort to keep your mind on what the speaker is saying. Fourth, try not to be   (15)   by appearance or delivery.   (16)  preconceived (事先形成的) judgments based on a personˈs looks or manner of speech. Fifth, suspend (延缓) judgment   (17)  you have heard the speakerˈs entire message. Sixth,   (18)  your listening by paying attention to main points, to evidence, and to the speakerˈs techniques. Finally, develop your note-taking skills. When done  (19)   , note taking is an

              excellent way to improve your concentration and to keep track of a speakerˈs   (20)  . It almost forces you to become a more attentive and creative listener.

              The desert tortoise is found in the Mojave and Sonoran Deserts in North America.It is listed as an endangered species under the United States federal Endangered Species Act and is considered "vulnerable" by the International Union for Conservation of Nature(IUCN).Despite the laws that protect them,their numbers are still in the decline.

                  The desert tortoise in the areas has lived for thousands of years.This animal is able to survive ground temperature over 140 degrees F and is known to live as long as 60 to 80 years.However,ninety-five percent of the life、of a desert tortoise is spent in the ground escaping the heat in a hole or passage in the ground Holes can he easily destroyed by off-highway vehicles that do not say on built roads.Disasters also occur when they seek shade under parked cars.

                  Desert tortoises are also harmed by several diseases such as the upper respiratory tract disease often found in adopted tortoises.Pet owners releasing sick tortoises into the wild has resulted in diseases being spread to wild tortoises.

                  The desert tortoise feeds on a dune (沙丘) primrose during spring.Non-native Sahara mustard (芥菜) seen in the background is a weed that competes with the native plants for water and nutrients.In some areas,mustard grows so densely that it is nearly impossible for desert tortoises to pass through.Vehicles,which do not stay on built roads and do not get washed frequently,contribute to spreading weeds.

                  Rubbish,such as burst balloon,is a danger to desert tortoises.The balloon can be mistaken for food by desert tortoises and,once consumed,may remain in the stomachs and intestines (肠) giving them a false sense of fullness that may cause them to starve.

              In a wheat field in France, a cat meets a black-bellied hamster (仓鼠). Too far from her burrow (洞穴) to run for shelter, the wild hamster rises on her back legs to face her enemy. The cat backs away. “Theyˈre afraid of nothing,” says Alexandre Lehmann, a biologist who has worked with these wild hamsters for the past 12 years.“They fight against cats and dogs and even farmers. They try to fight against tractors.”Itˈs a good thing that the black-bellied hamster wonˈt go down without a fight. Because in France, where only 500 to 1,000 remain in the wild, they are in a fight for their lives.

                  At the Stork and Otter Reintroduction Centre in Alsace, Lehmann and his colleagues breed captive hamsters and set the young hamsters free into the wild. But raising black-bellied hamsters isnˈt exactly easy. Remember, they have attitude. Forget humans — they donˈt even like each other.“You have to make sure the male and female donˈt kill each other,”Lehmann says.

                  Black-bellied hamsters might think of themselves as tough guys. But to a fox or an eagle, theyˈre just a four-legged snack. To survive, hamsters need to be set into a field with lots of leafy hiding places. Thatˈs a problem in Alsace, where most farmers plant corn. The corn hasnˈt sprouted (发芽) in early spring, when hamsters come out of their burrows from winter hibernation (冬眠). In the bare fields the hamsters are easy targets for their enemies.

                  Some older farmers donˈt want hamsters in their fields because of their reputation as crop-chewing pests. But most are willing to help, especially since the French government will pay farmers to grow early-sprouting crops such as alfalfa and winter wheat and allow hamsters to be set free on their lands. Itˈs a way to protect not just the hamsters, but also other small animals in leafy fields.

              We could say that any animal that knows how to find food,avoid being eaten, and raise babies is pretty smart. But cananimals learn and remember or can they solve problems?

              Many animals have good memories for where food is — auseful skill! Scrub jays (灌丛鸦) may be the champions. In oneexperiment, scientists put them in pre-made holes. After the jayshad hidden some food, they were taken out. Scientists mappedwhere the food was hidden and then removed it, which meant thejays couldnˈt find the holes by smell. But when the jays cameback again, they went right to the hiding places they had used. Inthe wild, they remember where thousands of holes are. Could youdo that?

              Another important smart skill is being able to spot shapesand generalize. This kind of test works best with animals that seewell and are interested in pictures. Call in the pigeons (鸽子)! Inthis test, pigeons had to learn to pick out photos with trees inthem, and to ignore photos that didnˈt include any trees. Oncethey had learned the rules, they were very adept at it.

              Scientists have to be careful when they test animals forsmarts, and the person giving the test has to know the animalreally well. In one experiment, a few bananas were hung out ofreach over a pile of sticks on the ground. Monkeys figured outright away how to get the bananas: pick up a stick and knockthem down. But clever elephants kept failing this test. Finallyscientists figured out why. An elephantˈs trunk works as both itshand and its nose. When it got the stick, it couldnˈt smell thebananas. When the elephants were given a couple of boxesinstead, they quickly used them to make a step and got thebananas.

              As weˈre learning, the world is full of smart animals, eachthinking in its own special way.
