Interactive Home-security Systems
Tarik Celebi, who lives in San Francisco suburb, takes his home-security system with him to work, to dinner, just about anywhere．By his cell phone, he "arms" his home-security alarm from his car before he leaves for work．During his workday, he gets e-mail alerts every time his front door opens, even though he's miles away．If the door opens at an unusual time -say midday when no one should be coming or going - he can order a 30-second video clip（片段） from the camera that watches the door．If it's just his  mother-in-law getting a package delivery, no worries．
Celebi is one of the first users of the latest interactive home-security systems．In addition to sounding alarms when the house is broken into and notifying homeowners or police, as traditional systems do, the interactive systems give users new ways to remotely control their systems and their home environment．Different from traditional home-security alarms, which homeowners typically have to press buttons on a keypad to turn on before they leave their homes, the interactive systems enable consumers to arm and disarm systems from smart phones, iPads and PCs, no matter where they are．
Most traditional systems are set up to sound an alarm if doors or windows are opened． The interactive systems give homeowners more options．For example, users can elect when they want to be notified．They might want an e-mail or a text every time a door is opened, or only during the hours of 3 to 4 p．m．, when kids come home from school．Like Celebi, they can add cameras and get video clips when doors open．That could be helpful in making sure kids aren't bringing friends home when they're not supposed to．
Nationwide, about 20% of homes have．traditional home-security systems．About half stop using them because they tire of the trouble．Being able to arm systems even while dashing to the subway or while at work will increase their usage of the new interactive systems．Although the new functions add costs to home security, the interactive-systems are believed to push home-security systems' usage rates closer to 30%, which would be a big movement for an industry that's been largely stuck at 20% for the past decade．"We all know it's going to get bigger, though we don't know how long it's going to take," Eric Taylor, an officer from San Francisco Security Department says．
小題1:What may Celebi first do if his front door opens at a wrong time when he is away?
A．Inform the police．B．Call his mother-in-law．
C．Arm the security alarm．D．Observe through video．
小題2:The interactive systems enable the user to ______．
A．improve his home environment remotely
B．lock his house's door while he is miles away
C．operate the home-security systems at any place
D．sound the alarm and inform the police at the same time
小題3:What's the advantage of the interactive systems over the traditional ones?
A．They are cheaper．
B．They are easier to set up．
C．They can give quicker reaction．
D．They have more ways to inform the users．
小題4:What is the last paragraph mainly about?
A．The importance of security industry．
B．The functions of the interactive alarms．
C．The popularity of home-security systems．
D．The market potential of the interactive systems．

小題1:D

Many people believe the glare from snow causes snow-blindness. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of “snow light”. The United States Army has now determined that glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren (少植被的) snow-covered terrain (地形). So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature eases this irritation by producing more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs (模糊), then is obscured (遮蔽), and the result is total, even though temporary, snow-blindness.
Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop scouring the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white terrain is overcome.
小題1:To prevent headaches, watering eyes and blindness caused by the glare from snow, dark
glasses are _________.
A．indispensable and essentialB．usefulC．ineffectiveD．a(chǎn)vailable
小題2:When the eyes are sore tears are produced to _________.
A．balance the pain B．treat snow-blindness
C．clear the visionD．loosen the muscles
小題3:Snow-blindness may be avoided by _________.
A．concentrating on the solid white terrain
B．searching for something to look at in snow-covered terrain
C．providing the eyes with something to focus on
D．covering the eyeballs with more fluid
小題4:The scouts shake snow from evergreen bushes in order to _________.
A．prevent the men behind losing their way
B．beautify the landscape of the terrain
C．warm themselves in the severe cold
D．give the men behind something to see
小題5:A suitable title for this passage would be _________.
A．nature's cure for snow-blindness
B．snow-blindness and how to overcome it
C．soldiers marching in the snow
D．snow vision and its effect on eyesight

A brand is a name, word, sign, symbol, design, or a combination of these, intended to identify the goods or services of a company or a group of companies. Another purpose of a brand is to contrast one company from another. The most important skill of professional marketers is the ability to create, maintain, protect, and enhance the brands of their products and services. Branding has become so important that today hardly any company or product is without one. Therefore, brand management is an increasingly important element in marketing.
Brand power refers to the relative strength of a company’s brand in the minds of consumers, and can influence consumers’ choice of products. Brands are powerful to the extent that they give high brand loyalty and strong brand associations, name recognition, perceived quality and other assets to a company. A strong brand can be one of a company’s most important assets.
High brand power provides a company with many competitive advantages. A powerful brand enjoys a high level of consumer brand awareness and loyalty. Because consumers expect stores to carry the brand, the company has more bargaining power when negotiating with retailers (零售商). And because the brand name brings high credibility, a company with a strong brand can more easily launch new products with the same brand name.
Many companies use the advantage of a strong brand power strategically to expand their business. When a company introduces an additional item with a new flavour, form, colour or package size in a given product category and under the same brand name, it is called a line extension. Another strategy is called brand extension. This involves the use of a successful brand name to launch new or modified products in a new category, thereby employing brand recognition in order to increase sales of new products.
Brand recognition is certainly important. Because consumers often hold long-standing perceptions about brands, high brand power ensure a company continued sales of its products.
小題1:What does the word “assets” in the 2nd paragraph mean?
A．points B．a(chǎn)dvantagesC．a(chǎn)spectsD．elements
小題2:All of the following statements are the advantages of a high brand power EXCEPT that______.
A．a(chǎn) high brand wins the loyalty of consumers
B．a(chǎn) high brand usually sets a much higher price
C．it’s easy for a high brand company to launch new products
D．a(chǎn) high brand company is more competitive when doing business with retailers
小題3:A brand extension ______.
A．happens when the company is developing a new product
B．means the expansion of a company’s business in its established field
C．takes place when the company introduces a similar item but with a new colour
D．refers to the use of an established brand name to promote a new product in a new category
小題4:What might be the best title of this passage?
A．Brand PowerB．Famous Brands
C．Company BrandsD．Brand Products

Starting a new school term is always exciting. It is a chance to see all of your friends again. But most exciting of all, the new term is an opportunity to take up new hobbies. As you know, it is common in Britain for students to take up new hobbies after the Christmas holidays. Promising to begin something new is a common New Year resolution for many school teenagers.
Most schools offer different kinds of hobby classes. Students take them in their free periods or after school. Some classes you have to pay for and others are free of charge. For example, I once took a free Wednesday evening gymnastics class that my school offered. But when I learnt how to play the drum my parents had to pay for the lesson, and they did so, like most parents, without any complaint.
The most popular extra classes at my school were piano lessons and drama club:  Both classes offered exams students could take. Because the extra classes may take up much time of the students, students with many hobbies sometimes felt more stressed than those without any. But they could enjoy their life better than those who didn't foster (培養(yǎng)) any hobbies at school. For example, they could build up good friendship with the persons who shared the common interest with them. Most important of all, the students with hobbies left school with many extra skills.
Frankly speaking, I haven't continued any of the hobbies I began at school. But I have never regretted taking them. After all, my best friend today is someone whom I met in my gymnastics class. The reason why we are still keeping in close touch with each other is that we have much in common.
小題1:The first paragraph suggests that it's children's nature          .
A．to value friendship
B．to make a promise easily
C．to copy others' behavior
D．to be curious about the new
小題2:The author's parents' attitude to hobby classes might be that of         .
A．a(chǎn)pprovalB．doubtC．unconcernD．disapproval
小題3:What is the biggest benefit children can get from taking up a new hobby?
A．They can enjoy a good time.
B．They can learn extra skills.
C．They can make more friends.
D．They will have things to share.
小題4:From the author's experience, we can learn that          .
A．free hobby classes are very popular
B．hobbies are a way of making friends
C．we must be careful when choosing a hobby
D．hobby classes may not last a long time
小題5:What is the purpose of the passage?
A．To introduce some hobby classes at school.
B．To tell readers how to choose hobby classes.

Speaking from my past experience, it is very difficult to find good friends that you can trust but once you have found them, they are worth keeping forever! Therefore, I think friendship is the most important relationship that anybody could have.
The qualities I look for in a friend are a good sense of humor but sensitivity when it matters. Also that friend would have to be strong-minded and highly spirited. I think that these qualities are the key qualities to look for in a good friend.
Even the strongest friends can still have arguments, although usually about more serious topics, rather than the usual teenage childish arguments. Some matters can seriously affect a friendship. If one of your friends started experimenting with harmful and dangerous drugs, what would you do ? A good friend would try to help as much as possible, whereas a bad example of a friend would simply shrug(聳肩) and turn a blind eye.
Not only the bad things affect friendship ---- good activities do too. Such as bonding with one another, not just by going out on a night with them but by spending quality time with them and talking to each other, which indicates a good ability to communicate. This is a key aspect of a good friendship.   
Good friends do not always have to be in the same age group as you. I have a good friend and she is 47 years old and I am 16.
Unfortunately, some people lose contact with their friends as they grow older, which is a sad way to lose a good friend.
I think friendship is one of the most important things in life because if you have no friends you will have no happiness.
小題1:According to the author, true friendship _______.
A．is easy to getB．deepens with time
C．needs managementD．a(chǎn)ffects one’s happiness
小題2:Paragraph 3 is mainly about______.
A．why drugs are bad for teenagers
B．problems that will test friendship
C．ways that help avoid arguments
D．whether a friend is trustworthy
小題3:According to the author, which matters least in friendship?
A．Age.B．Sensitivity.
C．Sense of humor.D．Communication ability.
小題4:Which of the following saying can match the author’s view on friendship?
A．Old friends and old wines are best.
B．A friend without faults will never be found.
C．A life without a friend is a life without the sun.
D．a(chǎn) friend to everybody is a friend to nobody.
