One of the problems with passwords is that users forget them. In order to remember them, people use simple things like their dog’s name, their birth date, or the name of the current month-anything that will give them a clue to remember what their password is.
For the curious hacker (黑客) who has gained access to your online account, this is the same as locking your door and leaving the key under the doormat (门垫).
To create a safe password that is easy to remember, follow these simple steps:
● You should never use personal information as part of your password. It is very easy for someone to guess things like your last name, pet’s name, child’s birth date and other similar details.
● There are tools available to help attackers guess your password. With today’s computing power, it doesn’t take long to try every word in the dictionary and find your password, so it is best if you do not use real words for your password.
● You can make a password much safer by mixing different types of characters. Use some uppercase letters (大写字母) along with lowercase letters (小写字母), numbers and even special characters such as “&” or “%”.
● Rather than trying to remember a password that is created using various character types and is not a word from the dictionary, you can use a “passphrase”. Think of a sentence or a line from a song or poem that you like and create a password using the first letter from each word.
For example, rather than just having a password like “yr $ 1 Hes”, you could take a sentence such as “I like to read the About. Com Internet network security website” and convert it to a password like “il2rtA! nsws” by using the number “2” for the word “to” and using an exclamation point (感叹号) in place of the “I” for “Internet”. You can use a variety of character types and create a safe password that is hard to figure out, but much easier for you to remember.
● You should use a different username and password for each login you’re trying to protect. That way, if someone figures out one of your passwords, the others are still safe. Another approach, which is less safe, but provides a fair balance between security and convenience, is to use one username and password for sites and applications that don’t need the extra security, but use unique usernames and more safe passwords on sites that require more security, such as your bank’s website.
1.How is a password made up of one’s dog’s name or birthdate?
A. It is safe and easy to remember.
B. It can get hacked easily by attackers.
C. It suits those who have a poor memory.
D. It is the most commonly used type of password.
2.According to the article, what is a passphrase made up of?
A. Different character types.
B. A long dictionary word.
C. The title of a song or a poem.
D. The first letter from each word of a sentence.
3.Which of these passwords might be the safest according to the article?
A. jessica208. B. yr $ 1 Hes.
C. HERO&37. D. il2rtA!nsws.
4.What’s the article mainly about?
A. How to make your passwords safer.
B. How hackers get access to computers.

Blame(责备) is one of the biggest problems that we meet in everyday life. 1. And when that doesn't happen, we blame other people, places or events that we think are the causes of our unhappiness.
Everything we feel comes from within us. 2.
If we create unhappiness for ourselves, the world will show us that unhappiness, but if we create joy, peace, and love for ourselves, this is what we will get back.
Can blame solve any problems? 3. When people did something hat makes us angry, afraid or hurt, we are doing nothing more than showing them the anger we feel inside.
We have choices about things that make us unhappy. We sometimes prefer to take the easier choices, the ones that keep us in our comfort zone(地带). 4. Sometimes we just have to go beyond our comfort zone, which may mean facing something we don't like. Perhaps we feel like a victim(受害者) and don't stand up for ourselves or speak up when we feel that people don't respect us. Maybe we are afraid of a situation, so we run away from it, instead of facing it with inner strength.
Whatever the problem is, we have a choice every day to face it with blame, fear, anger, guilt(内疚), or with love, kindness, peace. 5. Don't blame. Enjoy your day.
根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺，内容完整，并将答题卡相应选项涂黑。
A.Simply, it can't.
B. We create it and we live through it
C. How will you walk into your day?
D.We seem to know that the world is there to make us happy.
E. But how comfortable is it really when we are annoyed by someone else?

There are different ways in which people try to deal with the problem of energy. One way is the
greater production of common energy sources(能源)， such as coal， oil and gas. The trouble with these sources， however， is that they are not renewable.
Another way is energy conservation(节能)， which means using energy more efficiently(有效地).
In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights， the body heat of the people and the other equipment in it.
Finally， renewable energy sources are used even though they are often expensive to develop.
One form of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometre down. At six kilometres， therefore， it rises to nearly two hundred degrees. To get the heat， water is pumped(压；抽)down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.
1.The writer tells about the "special houses" because they __________
A. show the excellent skills of the builders
B. serve as an example of energy conservation
C. are heated by different sources of energy
D. are warmer than other types of houses
2.The underlined words geothermal energy in the third paragraph mean________
A. renewable source B. underground source
C. heat inside the earth D. temperature of the earth
3.At a place where the surface temperature is 15℃， how deep do you have to dig so as to get a temperature of 75℃?
A. One km. B. Two km.
C. Three km. D. Four km.

A sign is another kind of language. Here are some of them that you see on the roads.
Number One is a sign with the number thirty on it. When drivers see this sign, they must not go at more than thirty kilometers an hour. We see this sign when we are getting near a town. Number Two is a sign that we’re near a crossing. We must drive carefully. Number Three is a sign that there is a bend (拐弯) in the road. Again, we must drive slowly and carefully. It is not safe to go around a bend very fast. Number Four is a sign that there is another road coming in from the right. There is a junction (交叉) at this place. Number Five is a sign that there is a hill and Number Six is a sign that the road gets narrow. Drivers must go slowly and carefully. Number Seven has the word “SCHOOL” on it. This is a sign that there is a school at the side of the street or the road. Perhaps there are children going to or leaving school. So drivers must look carefully and go slowly. Number Eight is a sign with the letter “P” on it. The letter “P” means “Parking”. At some places, there are the signs “No parking” or “No waiting”. If a driver leaves his car near one of these signs, a policeman may come and write down the number of his car.
