We have some practically secret national parks on our lists that you'll want to visit this spring.
Guadalupe Mountains National Park
The most visually striking point here is El Capitan. The massive cliff (悬崖), 2.5 times as tall as the Empire State Building, towers over the rest of the park, which offers you a perfect spot for taking impressive pictures. You can also wander the Salt Basin Dunes, 2,000 acres of shockingly white sands. If you're taking very long hikes, bring plenty of water and some protein-rich snacks.
Katahdin Woods and Waters National Monument
The Katahdin Woods and Waters National Monument preserves more than 87,500 acres of wild rivers and thick forests. In addition to hiking and camping, Katahdin is a great spot for hunting and fishing. Bring some hiking boots and perhaps trekking poles (登山杖)to cross these rocky forest trails. The park has a day use fee of $5, and the first-come, first-serve campsites cost $8 per night.
North Cascades National Park
Though the snowy peaks of the North Cascades are dangerous in the winter, it turns into a thick and green park in the warmer months, filled with beautiful mountain valleys and clear lakes. You can take a guided nature hike or go fishing. Winter driving conditions in the North Cascades can be dangerous, due to water, frost, snow, or ice on the roads.
Organ Mountains.—Desert Peaks National Monument
This is not a national park，but is a national monument. It is home to several rare species of plants and animals，and lava (炫岩)flow. There are excellent chances for hiking, mountain biking, rock climbing, and nature photography, as well as overnight hiking. You can also go primitive camping anywhere in the monument for free. It's highly recommended that you should bring plenty of water and sunscreen, and know your fitness level ahead of time.

On the morning of July 4, a magnitude 6.4 earthquake rocked Southern California, destroying roads and sending people fleeing to safety. But that wasn't all the Earth had in store: Less than a day and a half later, a powerful magnitude7. I earthquake shook again. While earthquakes are not unexpected, the two most recent earthquakes are the largest that have struck this area in at least two decades. And a series of large and small aftershocks are expected on the way.
The two earthquakes struck in what's known as the Eastern California shear zone, where the Pacific Plate crushed against the North American Plate. The recent events occurred when two blocks of Earth moved side by side.
They seemed to have occurred along the same set of faults (断层)lying in an area known as the Little Lake fault zone-in most circumstances, earthquakes hit in a familiar order: There's a large earthquake followed by a series of smaller events. That's because the movement that occurs during a large earthquake causes increased force in the surrounding area.
But things are quite different in some circumstances, such as the recent pair of earthquakes in California, a relatively large earthquake just being the forerunner for an even bigger event. While the difference between 7.1 and 6.4 may seem minor，magnitude is a logarithmic (对数的) scale. An increase of a unit of magnitude is about 32 times more energy, which means that the energy the second earthquake released is roughly 11 times that of the first one.
''Fortunately, no deaths or major injuries were reported, '' says Bohon, an earthquake geologist. ''It was in a fairly unpopulated area, although a lot of people felt it'' She suggests people who live in earthquake-prone (地震频发的)areas check how prepared they are for the next event. And she also hopes that the earthquake early warning system can play a good role in saving tens of thousands of lives and schools will popularize the knowledge of geological (地质的) disasters among students.
1.What can be learned from the first two paragraphs?
A.The first earthquake was predicted before its occurrence.
B.The two big earthquakes hit the same area within one day.
C.The aftershocks are even more dangerous than the first two earthquakes.
D.The second earthquake is the largest one in Southern California since 2000.
2.What does the third paragraph mainly talk about?
A.The introduction of Eastern California shear zone.
B.The forming process of the Little Lake fault zone.
C.The geological facts about the two big earthquakes.
D.The potential disasters caused by plate movement.
3.The recent two earthquakes represent an unusual circumstance in the way that.
A.a major earthquake is followed by a larger one
B.there is a minor difference in their magnitude
C.the two earthquakes release a similar amount of energy
D.a series of smaller earthquakes occur in the surrounding areas
4.What contributes to the good point of the two Southern California earthquakes?
A.The popularization of earthquake knowledge in schools.
B.Peopled good preparation made in advance.
C.Small populations in the earthquake-hit area.
D.The earthquake early warning system.

As technology in the security field advances, so does the intelligence of the burglars in prevailing over this technology. Gone are the days when a simple alarm system, connected to your phone line, was enough to protect you from potential security risks.
Cellular alarm systems (蜂窝报警系统)are a replacement of the traditional wired phone line security networks. These systems work just like your cell phone. A cellular module is placed in the main control panel and it sends signals, without the use of wires, to the monitoring station. The cellular signal is sent via the data part of a cellular signal, much like a text message.
Sensors can be placed anywhere in your house. Whenever there is an emergency, the relevant sensor picks up the unusual activity and sends a cellular signal to the main control panel. The control panel serves more than one purpose, which sends a cellular signal at the same time to the monitoring service at the back end. The monitoring service later informs the relevant authorities in the form of high-pitched sirens (高音警笛声). Typically it takes a few minutes for emergency services to arrive at the scene. Depending on the efficiency of your monitoring service and the local authorities, help should arrive soon and deal with the potential threats.
It allows you to monitor your house remotely. All you have to do is simply access the cameras from your phone and keep a check for any unusual activities while you are not around. With cellular technology securing your house, you don’t have to worry about the power failure or even burglars cutting your phone lines.
Since these systems operate on batteries, you should be careful about when the batteries die out. There might be other appliances including microwave ovens and WiFi in the house that can cause disruption (干扰). Ensure that your cellular alarm system's range is not affected by the presence of these appliances. Many homeowners tend to go for wireless systems due to the ease of installation (安装）factor. However，keep in mind that a non-professional installation might actually leave the system easy to damage.
1.What do the underlined words ''prevailing over'' mean in Paragraph 1?
A.Improving. B.Defeating.
C.Worrying about. D.Looking into.
2.How can the authorities know an emergency is happening?
A.They hear high-pitched sirens.
B.They read the cellular signal.
C.They check the control panel online.
D.They notice the unusual activity via sensors.
3.What can we know about the cellular alarm system?
A.It looks like a phone. B.It is energy-saving.
C.It needs to be improved. D.It is wireless.
4.What's the purpose of the last paragraph?
A.To give cautions about the system.
B.To introduce the benefits of the system.
C.To call on people to watch out for security risks.
D.To teach people to install the system correctly.

Look on almost any street comer in America and you will see a fast food shop, the McDonald’s. Did you ever wonder why the McDonald's is so successful everywhere you go?
It certainly doesn't lie in the price of the food or the customer service there. If you stop for lunch at an airport McDonald's，half the continent away, the meal will be almost the same as the lunch you could order at the McDonald's that's closest to your home. What's more, anytime you eat at a McDonald's, you may feel nostalgia (怀旧之情)because the tastes are so similar to your first Happy Meal when you were a child.
The success of the McDonald's, which truly set the stage for other franchise (特许经销权) businesses all over the world, is owed to Ray Kroc. Ray，in 1954, partnered with Dick and Maurice McDonald, the founding brothers behind the first McDonald’s restaurant，to make this small restaurant a nationwide sensation (轰动). Ray's pushing the McDonald's farther than the founders proves an important concept in leadership: the Law of the Lid (盖子法则). The higher the person's ability to lead, the higher the lid on his or her potential.
The McDonald brothers understood how to run a business. They were excellent managers, but when they tried marketing the McDonald's concept, they failed. Their thinking patterns in leadership limited the lid of their potential on the level of what they can do or become. In contrast, the lid of potential in Ray's life was sky high due to his leadership. Between 1955 and 1959, he succeeded in opening 100 McDonald's restaurants. Today the company has more than 35,000 locations in over 120 countries around the world!
If you can get a handle on this law, you will see the unbelievable effect of leadership on every aspect of your life or your company. Wherever you look, you can find smart people who are only able to go so far because of the limitations of their leadership. That's why in times of trouble, organizations naturally look for new leadership. To lift the lid on your potential, continue your study of leadership.
1.What is most probably the key to the McDonald's success?
A.Its fair price. B.Its consistency in food.
C.Its Happy Meal for children. D.Its warm and friendly service.
2.What can we know about Ray Kroc?
A.He opened the first McDonald's.
B.He made the most popular food in the McDonald's.
C.He set up various stages for guests in the McDonald's.
D.He expanded the McDonald's into a worldwide business.
3.Which of the following statements will the author agree with?
A.Ray Kroc lacked a strong sense of effectiveness and leadership.
B.A person's leadership determines the potential of his business.
C.The lid on the McDonald brothers' potential is fairly high.
D.An excellent manager is also good at marketing.
4.What's the best title of the text?
A.Leadership counts B.Ways to realize our potential
C.Popularity of the McDonald's D.Secrets of running a business

Having roommates can sometimes be challenging. 1. It can be said, though, that nearly all issues are based on one roommate's lack of consideration for another.
Considerate people usually have consideration for others simply because it seems like the best thing to do. On the contrary, inconsiderate people usually don't think of themselves as such. 2. This can consequently cause major upset in the atmosphere of a room.
Not all roommates have the same daily schedule, so a common problem that roommates have to deal with is noise. It can be hard to coordinate a time for noise and a time for quiet. One may want to study and the other may want to play music. 3.
In the shared areas of the room, problems can arise in terms of how much space one or another roommate claims for himself. 4. This kind of space issue is often repeated in the refrigerator and other areas where each roommate needs an equal amount of space.
5. Although not all problems can be overcome easily, having discussions can sometimes prevent an issue from becoming a major point of tension in the room. For example, sometimes the solution to a problem with space is as simple as a verbal (言语的) exchange of views the problem.
A.There are certain things that roommates may decide not to share.
B.For example, one may take all the shared space for his or her own.
C.This can greatly contribute to the pleasure of living with roommates.
D.And it's hard to explain to these people that they are acting in inconsiderate manners.
E.So it's common that many people experience tough problems when living with others.
F.And one may have friends come over for a talk when the other is sick and trying to rest,
G.Open communication is the best way to come up with a solution to the above problems.
