When you are on a long road trip or in a traffic jam during a daily-commute ， it may seem harmless to connect your phone to your car's USB port．But unless you really need to use your phone，charging(充电)your iphone during your commute could be a big mistake．

    Why? For starters，the USB port in our car probably provides less electricity than your phone really needs to charge．As a result，your phone might stop working while it charges.

    Many people may notice that on their way home from work their phone charged very little during their 30-60 minute commute，"says Brad Nichols，an engineer at Staymobile．"It is mostly because that the phone is using more power than the car charger isproviding it．"

    Nichols also says that your phone could receive too much power，especially if you are using a cigarette lighter port to charge up．Most cigarette lighters can provide more power than most chargers can afford．If a charger cannot keep providing the proper power, it may make the phone broken．

    Charging your phone could do harm to your car's battery(电池)，too．This usually isn't a big deal for those who own new cars with healthy batteries，Nichols says．But if your car is older，you might not want to charge your phone through its USB port．

    Most importantly，it's not safe to use your phone while driving．"Anytime a person's hands leave the wheel or eyes leave the road，it becomes dangerous for them and the other people around them," Nichols points out．Bottom line：Play it safe，and wait until you get home to charge your phone．

People often think of the North Pole and the South Pole as similar frozen wastelands. They are both places with very cold temperatures and few people live there. However, the North and South Poles are not much alike as people may imagine.

The North Pole has no land, only thick ice. Temperatures seldom go above 32°F, at which water turns into ice. Most of the time, it stays below zero. In winter temperatures are usually as low as-30 F.

Although conditions were very poor, people tried for many centuries to reach the North Pole. More than 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on March 8th, 1909. It was really a hard trip for them.

There are few things more dangerous than crossing the Arctic on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, and even hunger. Most of the area is uninhabited. Few people can live in such a difficult place.

People might think that with such low temperatures for most of the year, the ice would be thick and hard. However, this is not true in the Arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice breaks into two opening lanes of water called "leads". Anyone who falls into a lead can be frozen to death in a few minutes.

 How many times have we told ourselves"I'm going to study from now on." or"I'm going to do more English exercises to improve myself next week."? And soon, all our decisions are gone.

 Being lazy is the most common thing in the world. It has become the biggest enemy(敌人) in front of us and"giving up" usually happens to us. {#blank#}1{#/blank#} The following ways are very useful.

 First, set a goal(目标) that you can get to. {#blank#}2{#/blank#} That's because you are used to the way that things are going, and even if you want to change, it's difficult. So don't try to conquer(征服) laziness in the beginning, just conquer some small things which you can achieve. As the saying goes, "Well begun is half done."

 Second, take action at once and then you will make progress little by little. Please remember"{#blank#}3{#/blank#}"

 Third, be responsible(有责任心的). To beat laziness, we need a bit of pressure. Pressure can encourage people, especially when it's good.

 At last, be confident (自信的) and keep doing it no matter what happens. You' ll meet difficulties and fall down. Just get up and keep going. You' ll make mistakes and get disappointed(失望的). It doesn't matter. {#blank#}4{#/blank#}

 In fact, being lazy is not terrible. Follow the advice above, keep your own promises and get started right now.
