4、e lions, elephants and rhinos on safari. The highlight of the trip is the opportunity to see gorillas in the mountain forests. However, you must be in good healthif a gorilla caught a cold, it would be extremely harmful to its whole family. How this vacation helps There are only about 600 mountain g
5、orillas left in the world as human activity has reduced the area where they can live. When you buy a permit, this will pay for the protection of the national park.Polar Bear Watching Country: Canada Departures: sixty trips between Oct. 1 Nov. 19 Every October and November, groups of polar bears gath
6、er in Hudson Bay. As they are normally lonely creatures, this is unusual. The bears wait for the ocean to freeze so they can hunt seals, so this is the perfect opportunity to see them. How this vacation helps If the Arctic ice cap melts due to global warming, polar bears will be in danger. We give a

Recent studies have found positive effects. A study
10、 conducted in Youngstown, Ohio, for example, discovered that greener areas of the city experienced less crime. In another, employees were shown to be 15% more productive when their workplaces were decorated with houseplants. The engineers at the Massachusetts Institute of Technology (MIT) have taken
11、 it a step further changing the actual composition of plants in order to get them to perform diverse, even unusual functions. These include plants that have sensors printed onto their leaves to show when theyre short of water and a plant that can detect harmful chemicals in groundwater. Were thinkin
12、g about how we can engineer plants to replace functions of the things that we use every day, explained Michael Strano, a professor of chemical engineering at MIT. One of his latest projects has been to make plants glow (发光) in experiments using some common vegetables. Stranos team found that they co
13、uld create a faint light for three-and-a-half hours. The light, about one-thousandth of the amount needed to read by, is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps. In the future, the team hopes to develop
14、a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plants lifetime. The engineers are also trying to develop an on and off switch where the glow would fade when exposed to daylight. Lighting accounts for about 7% of the total electricity cons
15、umed in the US. Since lighting is often far removed from the power source (电源)一such as the distance from a power plant to street lamps on a remote highway a lot of energy is lost during transmission(传输). Glowing plants could reduce this distance and therefore help save energy.1.What is the first par

18、e following can be the best title for the text?A.Can we grow more glowing plants?B.How do we live with glowing plants?C.Could glowing plants replace lamps?D.How are glowing plants made pollution-free?C Artemis is NASAs new lunar exploration program. Through the Artemis program, NASA will use new tec
19、hnology to study the Moon in new and better ways, and prepare for human missions to Mars. NASAs new rocket will carry the Orion spacecraft to lunar orbit. Then, astronauts will dock(对接) Orion at a small spaceship called Gateway, from where the crew will take trips to the lunar surface in a new human
20、 landing system, and then return to Gateway. The crew will return to the Earth aboard Orion. NASA will test the rocket and spacecraft in flight, and then send a crew for a test flight: Artemis 1 will be a test flight of the SLS rocket with the Orion spacecraft and with no crew. Artemis 2 will launch
21、 the SLS rocket and Orion with a crew, which will fly past the Moon, then circle it and return to the Earth. This trip will be the farthest one any human has experienced in space. Artemis 3 will send a crew, including the first woman astronaut and a black astronaut, to the Moon by 2024. The Artemis
22、3 crew will visit the Moons South Pole. No one has ever been there. At the Moon, astronauts will: Search for the Moons water and use it. Learn how to live and work on the surface of another celestial body (天体) where astronauts are just three days flight from home. Test the technologies we need befor
23、e sending astronauts on missions to Mars, which can take an up-to-three-year round trip. The Moon is a good place to learn new science. NASA will learn more about the Moon, the Earth and even the Sun. The Moon is a test bed for Mars. The Moon is a place to show that astronauts will one day be able t

27、Antarctica for over a century, but details as basic as what it looks like beneath all that ice have largely remained a mystery. Now, Earther reports that a team of scientists from Denmark, Norway, the Netherlands, and the UK has published the most detailed data yet on the continents subglacial topog
28、raphy (冰川下的地形) near the South Pole. As they report in the journal Geophysical Research Letters, central Antarctica is home to three large canyons (峡谷), one of which is deeper than the Grand Canyon and nearly as wide at some points. The researchers made the discovery by flying a plane with radar over
29、 the South Pole, a spot that isnt covered by satellites. They expected to find mountains beneath the ice sheet, but the wide canyons they found between the mountains came as a surprise. Of the three canyons, two hadnt been documented previously. The largest, the Foundation Trough(基础槽), measures 218
30、miles long, up to 22 miles wide, and 6,260 feet deep, putting it up there with the planets most impressive canyons. The discoveries are significant on their own, but the real purpose behind the research is to better understand how the West and East Antarctic ice sheets will react to rising temperatu
31、res. Human-caused climate change has made some of the continents ice not firm, and the West Antarctic ice sheet especially has been slowly melting to the sea. If patterns continue, the coastal glaciers supporting the large ice sheets could fall down, causing sea levels to rise a minimum of 10 feet.
32、If this happens, the canyons could be a major factor in the speed and direction of ice flow from central Antarctica to the coast. The event isnt likely to happen in the near future, but further study of Antarcticas topography will allow scientists to better predict when it might.1.Which of the follo
33、wing have scientists known little?A.The shape of Antarctica ice.B.The condition of Antarctica ice.C.The Grand Canyon.D.The beneath of Antarctica ice.2.Which of the following was found by a plane with radar?A.The Grand Canyon.B.The mountains.C.Three large canyons.D.Ice sheets.3.How do the scientists
34、feel about finding the wide canyons?A.Unexpected.B.Interesting.C.Ridiculous.D.Common.4.Whats the aim of the study?A.To document the three canyons.B.To find out how large the three canyons are.C.To know how ice sheets react to rising temperatures.D.To show the importance of the three canyons.第二节 (共5小

36、what you need to know to help keep yourself healthy. Stock up on food, water and household supplies. If there is a bird flu pandemic, youll want to minimize your chance of catching it by staying indoors; you might even be required to stay home if the government asks that people remain in quarantine(
37、隔离期). Youd better stock up today on at least 2-week worth of essentials such as water, food, emergency and medical supplies. _ Have an outbreak plan. It may feel odd or uncomfortable to talk to family members and loved ones about the worst-case pandemic scenario(预测). But if that scenario strikes, yo

39、egularly and getting sufficient rest can help keep you healthy in an outbreak and also keep you from catching the common cold. Particularly in a flu outbreak situation, it will be important to wash your hands with soap and water for at least 20 seconds. Be diligent about covering coughs and sneezes
40、with tissues. Moreover, know your essential health information such as your blood type, allergies, and past or current medical conditions. Make a list of that essential information for all the members of your family. _ And do make sure everyone in your household knows where to find it.A.Work out reg
