As data and identity theft becomes more and more common, the market is growing for biometric（生物测量）technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device（装置）that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence（节奏）with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to — regardless of whether someone gets the password right.
It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word ＂touch＂four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
28. Why do the researchers develop the smart keyboard
A. To reduce pressure on keys. B. To improve accuracy in typing
C. To replace the password system. D. To cut the cost of e-space protection.
29. What makes the invention of the smart keyboard possible
A. Computers are much easier to operate.
B. Fingerprint scanning techniques develop fast.
C. Typing patterns vary from person to person.
D. Data security measures are guaranteed.
30. What do the researchers expect of the smart keyboard
A. It’ll be environment-friendly. B. It’ll reach consumers soon.
C. It’ll be made of plastics. D. It’ll help speed up typing.
31. Where is this text most likely from
A. A diary. B. A guidebook C. A novel. D. A magazine.

Swap, Don’t Shop!
You keep hearing about recycling, right But it doesn’t end with bottles, cans, and paper. Clothing takes a huge amount of natural resources (资源) to make, and buying loads of new clothing (or throwing out old clothing) is not healthy for the environment. So what to do with all those perfectly-good-but-you’re-maybe-a-little-sick-of-them clothes piled on your bedroom floor
16 . It’s the best way to get rid of your used clothes, score clothes from your friends, and have a party all at the same time.
A successful swap depends on the selection of clothes, the organization of the event, and, obviously, how much fun is had. It’s really easy to do! Here are a few pointers.
Invite 5—10 people so you have a nice selection. 17 , and there may not be enough things to choose from; more than that, and it becomes uncontrollable.
18 . They should also prepare plenty of reusable bags to carry their “new” clothes home.
Put different types of clothing on different surfaces in the room. 19 . Place a few mirrors around your room so people can see how things look when they try them on. One of the ground rules of the swap should be that everyone must try on the clothes before they take them—things always look different when you put them on.
Set a starting time. Maybe you say “go,” or turn on a certain song, or whatever. 20 . And don’t forget to put out some cookies and fruits. Remember, it’s a party!
A. Less people than that
B. Hold a clothing swap
C. If two people are competing
D. Just keep music playing throughout
E. Donate whatever clothes are left over
F. Have everyone put their clothes in the right spots
G. Tell everyone to bring clean clothes in good condition

China has become the first country to land a spacecraft on the far side of the moon. The unmanned Chang’e-4 probe (探测器) -- the name was inspired by an ancient Chinese moon goddess -- 61 (touch) down last week in the South Pole-Aitken basin. Landing on the moon’s far side is 62 (extreme) challenging. Because the moon’s body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot 63 it could send signals to the spacecraft and to Earth. The far side of the moon is of particular 64 (interesting) to scientists because it has a lot of deep craters (环形山), more so 65 the familiar near side. Chinese researchers hope to use the instruments onboard Chang’e-4 66 (find) and study areas of the South Pole-Aitken basin. “This really excites scientists,” Carle Pieters, a scientist at Brown University, says, “because it 67 (mean) we have the chance to obtain information about how the moon 68 (construct).” Data about the moon’s composition, such as how 69 ice and other treasures it contains, could help China decide whether 70 (it) plans for a future lunar (月球的) base are practical.

Be smart online learners
Online learning is an important way to study recently. But being smart online learners has its advantages and disadvantages.
First of all, as smart online learners, we can make full use of the most extensive educational resources to broaden our horizons. Besides, We can take the initiative in our study by ourselves without time and space limit. Of course, its disadvantages are also obvious. Faced with all kinds of information on the internet, We can't tell the difference between the true and the false, which may be harmful to our study and life. On the other hand, online learning itself has some imperfections, making it difficult for us not to be affected.
In conclusion, we should have a good understanding of its advantages and disadvantages and find a proper way to make our study more efficient.
