Password (密碼) strength has been a topic about the Internet lately. I have seen lots of clever methods for generating and remembering strong passwords. Some are better than others, but in my opinion, none are adequate. Here's the problem: It doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked(侵入), like Gawker media, or even Sony did, and now your super­strong password has been stolen, and every site on which you used that password has been accessed.
So, the bottom line is that no matter how strong your passwords are, and no matter what clever tricks you use to help you remember them, if you surf internet often, the only truly secure password system is what you need.
Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database. The LastPass database is stored online, on LastPass's servers. LastPass recognizes the site you're on and automatically logs you in (after, optionally, asking you to re­enter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different, unique, very strong password for every site you log into, but you only have to remember one master password. It's the best of both worlds.
One argument against LastPass is that if their database is attacked, then all of your sites are in danger, and that's true, but given that their entire line of work is keeping that information safe, I'm willing to take that chance. The alternative is rolling dice(擲骰子) or picking phrases to create passwords, writing all of them down on a piece of paper or something, and then having to manually type them in when I go to a site. A terrible mess.
There is a free version of LastPass, with some additional features unlocked if you pay a $12 a year subscription.

Worried about how many calories you will get in that piece of pizza, chocolate cake or bag of chips? A new iPhone application (應(yīng)用程序) MealSnap may help. Users just need to take a picture of the meal with the phone, and it will give a calorie read-out almost immediately.
MealSnap was developed by DailyBurn, a health social network that focuses on helping its users lead healthier lifestyles. It has created several other health and diet-related iPhone applications. The application gives users a quick reply. To do that, it matches the taken picture to a databank (數(shù)據(jù)庫) with the calorie information of nearly 500,000 kinds of food. Users then get the range of calories for the meal that is photographed.
We started with something simple—an apple. A couple of minutes later, the application replied that it was an apple and between 64 and 96 calories. More impressive was the reply we received after sending a photo of a mixed salad bowl. MealSnap replied that the bowl contained “yellow rice with corn, boiled eggs and beans” and that the food was between 532 and 789 calories.
Mr. Smith, director of DailyBurn, said that usual calorie counting needed a long time, but that the application made it easier to know the calories in food. That is why it is so popular among those who are trying hard to lose weight.
In addition, MealSnap can act as a food diary. No need to write down what they’ve eaten, the photoes will be stored. The users can keep a visual log (視覺的記錄). Mr. Smith said, “it’s like a food journey, but easier. All you do is to take the picture. The simple act of recording something can cause a psychological (心理的) change that can help people on their health journey. Knowing the calorie range makes me think more about what I’m eating.”
小題1: The purpose of DailyBurn is to________.
A．help people find ways to lose weight
B．make iPhone more popular
C．persuade people to buy iPhone products
D．help people have a healthy life
小題2: What can be learned from the third paragraph?
A．MealSnap is only useful for simple things.
B．The result of MealSnap isn’t always right.
C．MealSnap can also tell what the food is.
D．MealSnap needs a long time to show the calorie range.
小題3: Which of the following statements about MealSnap is TRUE?
A．It has been put into the market.
B．People will have a physical change by using it.
C．It’s popular because it was developed by DailyBurn.
D．People have to link iPhone with the Internet to use it.

To most of us，school means classes，teachers，schedules，grades，and tests.But for the children at Sudbury Valley School in Massachusetts，school is very different.
Firstly，there are no lessons.All the children，aged between 4 and 19，do whatever they want.There are no teachers—only “staff members”．The idea behind this is that you do not need to make children learn，because children want to learn anyway.“You do not need to say to a three year­old，‘Go explore your environment.'You can't stop them！” says Daniel Greenberg，a founder of the school.“But if you make children do what you want all day，they will lose all taste for learning.”
At Sudbury Valley School，you will permit children to talk，read，paint，cook，work on computers，study French，play the piano，climb trees or just run around.Two boys spent three years just fishing!
The other way that Sudbury Valley School is different is that the children can decide the rules.Every week，there is a school meeting where both children and staff have one vote each—even the four­year­olds.They decide the school rules，how to spend the school budget，and even which staff they want and do not want any more.
When the school first opened in 1968，people said it would never work.But today，the school has 200 students，and 80%of its students go on to college. Even the two boys who went fishing all the time have successful careers today.One of them is a musician and the other is a computer scientist.
小題1:What is the main topic of the article?
A．An unusual school.B．Children's hobbies.
C．A school without rules.D．Education in the US.
小題2:What does the school believe?
A．Teachers cannot teach children Well.
B．Children learn best when they do what they want to do.
C．Learning is for adults—children should only play.
D．Children should only learn about one thing at a time.
小題3:What does Daniel Greenberg say about three­year­olds?
A．They love learning.
B．They are very naughty.
C．They want to be outside all the time.
D．They are too young to learn anything.
小題4:Who has the most power in the school meetings?
A．The older children have more power than the younger children.

The first robot rover to land on the Moon in nearly 40 years, China's Jade Rabbit, has begun sending back photos, with shots of its lunar lander(登月飛行器). Jade Rabbit rolled down a ramp lowered by the lander and on to the volcanic plain known as Sinus Iridum at 04：35 Beijing time on Saturday (20：35 GMT)．It moved to a spot a few metres away, its historic short journey recorded by the lander. On Sunday evening the two machines began photographing each other. A Chinese flag is clearly visible on the Jade Rabbit as it stands deployed on the Moon's surface.

Ma Xingrui, chief mander of China's lunar programme, declared the mission (任務(wù))a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China's ambitious space programme, says BBC science reporter Paul Rincon.
The lander will operate there for a year, while the rover is expected to work for some three months. The Chang'e­3 mission landed some 12 days after being launched atop a Chinese­developed Long March 3B rocket from Xichang in the country's south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13：00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球車) in Shanghai a few years ago ­ it's a wonderful technological achievement to have landed，” Prof Andrew Coates, from UCL's Mullard Space Science Laboratory, told BBC News.
Chang'e­3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod­2, which was kept warm by polonium(釙)­210. But the six­wheeled Chinese vehicle carries a more sophisticated payload(復(fù)雜的有效負(fù)荷), including ground­penetrating radar which will gather measurements of the lunar soil and crust.
小題1:What does the text mainly talk about?
A．China's space and aeronautics industry develops quickly.
B．The importance of China's space and aeronautics industry.
C．China's Jade Rabbit Moon rover sends back first photos.
D．Chang'e­3 is the third unmanned rover mission to touch down on the lunar surface.
小題2:After ________ years' hard and scientific work, the first soft landing on the Moon has made such great progress.
A．nearly 40B．37
C．64D．more than 40
小題3:The purpose that the Chinese moon rover has visited the moon is to ________.
A．do some research about the moon
B．be the first settler on the moon
C．to plant the Chinese flag onto the moon
D．send a lovely jade rabbit onto the moon
小題4:From the text, we know that the lander began its descent on Saturday just after ________ Beijing time.

Have you seen a yellow-and-black salamander (火蜥蜴)? How about a scarlet frog? Scientists haven’t spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct?
Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads(蟾蜍), and salamanders are amphibians.
The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They’re also looking for species in Africa, Asia and Australia.
Scientists are hopeful that they’ll find the amphibians—and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live.
“If researchers can find the missing creatures, they might be able to figure out how to save them,” explains expert Robin Moore. He began searching for the amphibians earlier this month.
“This search will tell us a lot about how amphibians are doing,” Moore told WR News. “I don’t know what we will find, but that makes the search even more exciting.”
Lost in the Wild
Scientists’ hunt for missing amphibians is under way. Read about some of the species they hope to find.
Turkestanian salamander
This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since.
Gastric brooding frog
Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss.
Rio Pescado stubfoot toad
Last sighting: 1995, in South America
Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.
小題1: Which of the following animals hasn’t been seen for over a century?
A．Rio Pescado stubfoot toad.
B．Gastric brooding frog.
C．Turkestanian salamander.
D．Scarlet frog.

The biggest danger facing airlines nowadays may not be a terrorist with a gun, but the man with portable computer in business class. In the last 16 years, pilots have reported well  over 100 incidents that could have been caused by electromagnetic interference  (電磁干擾).  The source of this interference remains not proved, but increasingly, experts are pointing the  blame at portable electronic devices such as portable computers, radio and cassette players  and mobile telephones.
RTC.A. an organization which advises the aviation  (航空 )industry, has suggested that all  airlines ban such devices from being used during "critical" stages of flight  particularly take-  off and landing. Some experts have gone further, calling for a total ban during all flights .Cur- rently , rules on using these devices are left up to individual airlines. And although some air- lines prevent passengers from using such equipment during take-off and landing, most are un- willing to carry out a total ban, given that many passengers want to work during flight.
The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices send out radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory. they have no way of knowing whether the interference might be. dangerous or not.
The fact that aircraft may be fragile to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can 't hear the instructions to turn off his radio because the music's too loud.
小題1:What is said about the over 100 aircraft incidents in the past 16 years?
A．They may have been caused by the damage to-the radio systems.
B．They may have taken place during take-off and landing.
C．They were proved to have been caused by the passengers portable computers.
D．They were suspected to have resulted from electromagnetic interference.
小題2:Why is it difficult to predict the possible effects of electromagnetic fields on an airplane 's computers?
A．Because it is extremely dangerous to conduct such research on an airplane.
B．Because it remains a mystery what wavelengths are liable to be interfered with.
C．Because research scientists have not been able to produce the same effects in labs.
D．Because experts lack adequate equipment to do such research.
小題3:Few airlines want to perform a total ban on their passengers using electronic devices because_______
A．they don't believe there is such a danger as radio interference
B．the harmful effect of electromagnetic interference is yet to be proved
C．most passengers refused to take a plane ,which bans the use of radio and cassette players
D．they have other effective safety measures to fall back on
小題4:The passage is mainly about_________.
A．a(chǎn) new rule for all airlines
B．the disadvantages of electronic devices
C．a(chǎn) possible cause of aircraft incidents
D．effective safety measures for air flight

My six-year-old came home from school this week with two envelopes. One was for a donation to help people in the Philippines. The other was to help hungry families have a Thanksgiving meal.
“I’ll put a check in each of these. Then you can add your own money from your piggy bank, okay?” I said, thinking he’d be so excited to put his own stamp on things.
“That’s okay, mom. You put money in. I don’t want to waste mine,” he sweetly sang as he colored. “I want to fill my bank all the way up.”
Ack! I guess I know what our dinnertime discussion will be about tonight, I thought.
I had figured that through watching his parents donate items, helping us take toys from time to time to needy kids and putting money in the basket at church, he would just understand why it was important to help people in need — and even want to do it himself.
But of course he doesn’t really understand yet. “There’s a big disconnect between the people ‘over there’ and my piggy bank,” said parenting educator Vicki Hoefle.
“There’s nothing wrong with the child. There’s just no connection.”
As for having that conversation immediately, or forcing my son to put money into the envelopes: “Try not to do it now,” Hoefle said. Teaching a child about donating their own money or toys or time to people in need “should be a gentle introduction into what we hope will be a way of life for our kids.”
She suggested these things to help children understand the importance of giving:
* Just talk about it. Then explore the issue from a perspective he can understand.
* Use the course of a year to introduce kids to opportunities. That way, they won’t be shocked when you ask them to stuff their own money into an envelope （like this writer just did）.
* Pick a family charity for the year and have a conversation about how you all can help throughout the year.
* Think of this not as something you must teach, but as something to expose them to.
At her house, Hoefle said, “When you got something new, you gave something up.” Each birthday, her children would pick what toys they had outgrown and give them away. “There was a comfort in it. It just became a natural part of the kids’ lives.”
So I will fill those envelopes alone this time. But I’ll make sure he understands why they should be filled—gradually.
小題1:When the writer asked her son to give money to help the poor, he __________.
A．declined to donate
B．sang a sweet song
C．put all his money in a bank
D．seemed very surprised
小題2:Hoefle’s attitude towards children’s unwillingness to donate money can be best described as “_______”.
A．criticalB．tolerantC．positiveD．worried
小題3:Which of the following is Hoefle’s approach to educating kids about charity?
A．Giving courses about charity.
B．Setting a rule for children to give.
C．Inviting a lot of poor people home.
D．Giving children enough real life chances.
小題4:What can we learn about the writer from the passage?
A．She often makes donations for people in need.
B．She taught her son a lesson over dinner that evening.
C．She is at a loss as for what she should do next.
D．She invited a parenting educator home for advice.
小題5:What is the best title of the passage?
A．Kids, please help those in need.
B．Why are kids unwilling to donate?
C．Kindness is lost in the young generation.
D．How can we help kids learn generosity?
