【題目】We are more dependent on technology now than ever before-and for good reason. Our cell phones have more capabilities than laptops did 5 years ago. Technology is quickly becoming faster, more reliable, and yes, more portable.

Because of this, now is a great time to look into purchasing a laptop. Laptops now have the same computing power as desktops and are the least expensive they’ve ever been. If you’ re constantly on the go, it makes sense to have one.

We feature a lot of hot tech deals here at MakeUseOf, but if you’re in the market for a laptop, I've collected the top two laptop computers for you. I only looked at laptops priced under $1,000 that had at least 4GB of RAM, a dual-core processor, and came with Windows 7. Let’s see what we camp up with!

1. Sony Vaio FW 560F/T

Processor: Intel Core 2 Duo P7450/2. 13GHz

Memory: 6 GB（8GB Max）

Hard Drive: 500GB

This Sony Vaio laptop has a lot of features that make it very attractive. With a 16-inch screen, it is very slim. It has Blu-ray playback and decent gaming performance, although it doesn’t support 1080p. It makes for a very good multimedia notebook.

2. Samsung NP-R580-JSB1US

Processor: Intel Core i5 15-430M/2. 26GHz

Memory: 4 GB

Hard Drive: 500GB

This laptop comes with a Core i5 processor, NVIDIA graphics, and Blu-ray support. I’ve read that the touch-pad is uncomfortable at times, but the processing power and graphics make it a great laptop with decent battery life.

【1】What is the normal memory of Sony Vaio FW560F/T?

A. 8G B. 5GB C. 4GB D. 6GB

【2】What’s the similarity of Sony Vaio FW560F/T and Samsung NP-R580-JSB1US?

A. Processor B. Memory

C. Hard drive D. Features

【3】The underlined phrase “ makes sense” in Paragraph 2 can be replaced by____.

A. is dependent B. is meaningful

C. is reliable D. is portable

【4】Which of the following is true?

A. Our cell phones have more capabilities than laptops did 3 years ago.

B. Laptops now are the most expensive they’ve ever been.

C. Sony Vaio laptop is very attractive with a 16-inch screen.

I am more than glad to tell you about my trip in Xi’an, a capital city of Shaanxi Province.

What impresses me deep is its natural scenery and long history. First, as it is known to the world, Xi’an has a long history and is the birthplace of Chinese civilization. Its cultural and historical significance of the area, as well as many historical sites, help Xi’an enjoy the title of “Natural History Museum”. The Terracotta Warriors, as example, are praised as “the eight wonder of the world”. Second, it is in a favorable geographical location surrounding by the Wei River and Qinling.

One day when I was at four, I played outside in the courtyard. I caught sight my dad’s truck and thought he shouldn’t have to drive such a ugly truck. Then I spot a tin of white paint. I picked up a brush and started painting white dot all over the truck. I was on the roof busy doing the job while my dad walked up, looked at me in surprise. Before I explained anything, he said cheerful, “Angela, that’s the pretty truck I’ve ever seen!” He could have blamed me. But he didn’t. Therefore, he lifted my little soul with those encouraging words.

Pilates, yoga and the running machine get all the attention when it comes to popular ways to stay healthy.

There is, however, a more humble exercise that might not be so attractive, but has all the benefits — walking.

Certified fitness professional Jolynn Jaekel explains, “What I love about walking is that anyone can do it at any age and any fitness level. Plus, it is good for your heart, your head and your wallet.”

A recent report details the health benefits of walking. The report found that walking regularly to fulfill the 150 minutes of moderate physical exercise every week, recommended by the UK's chief medical officer, could save 37,000 lives each year. Scientists at the Lawrence Berkeley National Laboratory in California found that quick walking reduces the risk of heart disease more effectively than running. They observed participants aged between 18 and 80 over a sixyear period and found that walking reduced the risk of heart disease by 9.3%, while running reduced it by 4.5%. And there is even more good news: 30 minutes of quick walking over five days could help you sleep easily, according to research by Oregon State University. The study by the university showed that walking helped participants sleep better and feel more alert during the day.

The sooner you get started, the sooner you'll notice the differences in your mind and body. So, go out for your 30minute walk in a nearby park or green space.

【題目】A mechanical bicycle lock, like a U-lock, should be attached to a solid and immobile object like a rack（架子）to ensure safety. However, these racks are quite rare and popular, thus often occupied and although a bicycle lock prevents the bike from being carried away, as it fixes single parts like the frame or the wheels, other parts can be dismounted. Therefore an electronic system, consisting of several sensors, can extend the range of protection with only few components and less effort.

The ‘RFID Bikealarm’ is a motion sensitive electronic alarm system that is attached to the rails of a bike saddle（座椅）. Featuring omnidirectional（全方位）movement sensing to detect tiny movements or speeding-up and a small whistle emitting >120dB alarm sound to scare off potential thieves by arousing attention.

The internal microcontroller uses a complex computer program to distinguish between a serious theft and harmless shaking movement as it senses and adapts to the environment. The usage is quite simple: identify yourself by holding the RFID tag close to the case to lock or unlock the alarm system signaled by feedback sounds. The RFID-technology is predestined for achieving this simple and secure interaction because it doesn’t require any complex system, interaction or other devices—just a small tag.

The ‘RFID Bikcalarm’ is meant to be a useful add-on to mechanical bicycle locks as it massively extends the range of protection with few components. It is low-cost, durable and easy to use. The internal battery can be charged by USB.

【1】What does the underlined word “dismounted” in Paragraph 1 most probably mean?

A. fixed up B. found out

C. taken away D. locked up

【2】Which of the following shows the right position of the RFID Bikealarm on a bicycle?

A. B.

C. D.

【3】What will happen when someone steals a bike with the RFID Bikealarm?

A. Noises will be made. B. The bike will be locked.

C. The thief will be identified. D. Messages will be sent to the owner.

【4】Which of the following is a feature of the RFID Bikealarm?

A. It uses complex parts. B. It needs a rack to prevent bike theft.

C. Its high price scares away its buyers. D. It works together with a mechanical lock.
