A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again.
Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim that the receivers can be shrunk(缩小) to fit inside a regular cell phone. Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico.
“This is one of the most important technology developments for the future of the positioning industry,” says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.
As for the Locata’s correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis(轴). Morin said it should be possible to get the exactitude down to 5cm.
The tests were performed in an open desert where GPS also worked beautifully, but its signal was weak—like a car headlight from 20,000 kilometers away—and easily cut off by solid objects(实心的物体). Locata’s signal was far stronger, though not guaranteed to work in a complex urban environment, said David, speaker of the UK’ s General Lighthouse Authorities.
Locata’s technology will face competition in the race to transform indoor navigation. But it could shine in specific areas, Gambale said. Robots with Locata could easily navigate inside buildings without the complex optical(视觉的) systems they need at the moment. And the process that handles correct location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. It would be small and cheap enough for smart phones and it should be available within five years—a similar path to the one GPS took on its way towards the world, he said.

In the fall of 1985, I was a bright-eyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.
My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to withdraw from college to care for her. It meant that school and my personal dream would have to wait.
Then I got married with another dream: building my family with a combination of adopted and biological children. In 1999, we adopted our first son. To lay eyes on him was fantastic---and very emotional. A year later came our second adopted boy. Then followed son No. 3. In 2003, I gave birth to another boy.
You can imagine how fully occupied I became, raising four boys under the age of 8. Our home was a complete zoo---a joyous zoo. Not surprising, I never did make it back to college full-time. But I never gave up on the dream either. I had only one choice: to find a way. That meant taking as few as one class each semester.
The hardest part was feeling guilty about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to quit, but I knew I should set an example for them to follow through the rest of their lives.
In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree!
I am not special, just single-minded. It always struck me that when you’re looking at a big challenge from the outside it looks huge, but when you’re in the midst of it, it just seems normal. Everything you want won’t arrive in your life on one day. It’s a process. Remember: little steps add up to big dreams.
1.When the author went to Howard University, her dream was to be __________.
A. a writer B. a teacher
C. a judge D. a doctor
2.Why did the author quit school in her second year of college?
A. She wanted to study by herself.
B. She fell in love and got married.
C. She suffered from a serious illness.
D. She decided to look after her grandma.
3.What can we learn about the author from Paragraphs 4 and 5?
A. She was busy yet happy with her family life.
B. She ignored her guilty feeling for her sons.
C. She wanted to remain a full-time housewife.
D. She was too confused to make a correct choice.
4.What does the author mostly want to tell us in the last paragraph?
A. Failure is the mother of success.
B. Little by little, one goes far.
C. Every coin has two sides.
D. Well begun, half done.
5.Which of the following can best describe the author?
A. Caring and determined.
B. Honest and responsible.

Patience is of great important in our daily life. Once I waited a bus to come at a stop. 30 minutes past, but no bus came. Both upset and annoyed, I decided to walk on feet. But no sooner had I left when the bus arrived. I thought if I had waited for one more minute, I would have caught it. If I chose to take a next bus, I would have to wait for other 30 minutes. Only then do I realize my problem. Being impatient will possibly waste all the effort that we have put it in. Now whenever I am close to lose my patience, I’ll think of this experience

Because I will be away for a few days after Spring Break, I am writing this during the actual holiday, when I can use time to catch up on a number of purely administrative (管理的) items.
First of all, you should have received the letter I sent out on April 2 advising of the transition (过渡) arrangements to new leadership at ISM (International School of Moscow). In that letter I pointed out that Dr. Paul Malone will be arriving in Moscow on Monday, May 4th, and that I will work with him during that week to ensure smooth transition. My last day at ISM will be Friday, May 8th.
Several people have asked me why I required Dr. Malone to come early. There are many problems facing ISM at the moment which have major implications (影响) for the future, and it makes sense for the new director to come aboard before the end of the school year. This will give him the chance to play a major role in the planning process for 2014—2015 and beyond. The fact that Paul Malone is able to arrive in early May is good for the school. I have been working closely with him, and will do everything possible to see that he can move in easily when I leave. From here I will go to Hong Kong for a couple of weeks to spend time in my new situation, and then I will return to the United States for a few weeks’ vacation.
In the most recent edition of the Compass(a kind of paper of ISM), I wrote briefly what I consider to be the major challenge for ISM in the future. I am sure that the new leadership of the school will be able to face those challenges in an active manner, which will ensure a strong future for the school. I shall certainly watch the progress of the school with interest. The results of the school for the past few years have been quite outstanding, and I fully expect that level of performance to continue.
1. We can infer from the text that the writer was the ________ of ISM.
A. director B. employee
C. teacher D. student
2. Why should Dr. Malone come to ISM early?
A. To work closely with the author.
B. To do everything possible for the school.
C. To move in easily when the author returns.
D. To work with the author for a few days and make a future plan.
3. From the text, we learn that ________.
A. Paul Malone is a capable man
B. the writer is a best friend of Paul Malone’s
C. Paul Malone will work with the writer for several years
D. the writer will do his best to help Paul Malone to work well at ISM

However, 3. . They can include details, and a person with a special interest can take the time to read them. Others can stick to the headlines.

When I was a boy, I used to love walking in the woods around my home.My mom warned me several times never to travel so far that I would lose sight of the house.Being a typical boy, however, I soon found myself hiking further and further away, testing just how far I could go into the woods without getting lost.After losing my way once for two hours, though, I decided that I had better leave a trail the next time I went for a walk.
The very next day I decided to try it.I walked into the woods until the house was out of sight.Then I broke a small branch on a young tree to mark my place.I wandered further in and broke another limb and then another.In a few spots where there were no limbs small enough, I snapped the heads off the low plants that were growing where the sunlight broke through the trees.After a while I finally got tired and decided to head back.Turning around I easily found my tracks, but instead of being proud I felt sad.I could see the trail of destruction I had left in the woods going on and on.Looking at the broken limbs and dead flowers I wondered if God was disappointed in me and I vowed never to do that again.Instead, I started to cherish my times alone in the woods with nature.I’d sit by the streams and listen to them sing.I’d watch the birds and squirrels.I’d bend down to smell the flowers.And I even buried an acorn or two hoping that one day an Oak might grow.
There is an old Native American Saying that goes “We will be known forever by the tracks we leave.” As I have grown older and wiser, I have done my best to never leave a trail of destruction in my life as I did in the woods that day.I have instead tried to leave tracks of love, kindness, goodness, and compassion and I have strived to show others that they can do the same.May you always leave tracks of joy as you follow your own trail of love.
1.When the boy headed back from the woods, he felt sad because ______
A.he lost his way in the woods
B.he could find his tracks so easily
C.he left many trails of destruction
D.God was very disappointed in him
2.The boy took off some branches to ______.
A.protect himself
B.make his way out
C.see the sun clearly
D.leave some marks
3.The author wrote the passage to ______.
A.call on us to leave tracks of virtues in life
B.inform us that we shouldn’t destroy trees
C.tell us how to avoid getting lost in the woods
D.show us ways to get back home in the forest

There are all sorts of good sensible reasons to avoid getting angry. Not only does it make us feel bad, it also makes us do stupid things without noticing the risks and it can be self-destructive( 毁坏性的). 1. But like all emotions, anger has its purposes, which can be used for good effects.
Anger is a motivating force.
In fact anger itself is a kind of positive energy and a powerful motivating force. 2. When we see something as beneficial, we want it more when we are angry. So, when used right, constructive anger can make us feel strong and powerful and help push us on to get what we want.
3.
It may sound like a strange thing to say, but angry people have something in common with happy people. That's because both tend to expect favorable results. By comparison those experiencing more fear are more pessimistic(悲观的) about the future and expect further terrors.
Anger can benefit relationships.
Society tells us anger is dangerous and we should hide it .The problem is that when we hide our anger, our partner doesn't know he's done something wrong. And so he keeps doing it. 4. The expression of anger, if reasonable and aimed at finding a solution, can actually benefit and strengthen relationships.
Anger provides self-understanding.
Anger can also provide understanding into ourselves, if we allow it. Getting angry leads to a positive outcome. Anger help discover our own faults. If we can notice when we get angry and why, then we can learn what to do to improve our lives. 5.

C.Anger reduces violence.
D.Angry people are more optimistic.
E.Most of us treat our anger as though it's unreasonable, unshowable and unmentionable.
