1 . They ____________ on their ideas at the last minute. (放弃) (根据汉语提示完成句子)

3 . In a world where nearly 6 million fingerprint records of government employees are stolen in one computer hack, and where millions of people are victims of identity theft every year, the next step in cyber-security may well be mapping your brain.

Researchers at Binghamton University are working on a biometric (生物特征的) system that records how your brain reacts to certain images. With a little more polishing, the scientists’ brainchild could become the way you get into a safe deposit box, your office or past scanners at the airport. It could replace the password for your online banking, your e-mail or your social media accounts.

They started their project by measuring the brain waves of 30 subjects. The subjects were fitted with a cap that had 30 electrodes attached to it, and then shown various images and symbols — celebrity faces, words, pictures of food — on a computer screen in 200-millisecond bursts. The brain’s reaction was recorded.

The idea is that every time a person needs to use a “password”, he or she goes through the same procedure, and the results are matched to their first-time reaction. If the “brainprint” is cracked — like what happened to the fingerprint records — then the system is merely reset by running another set of images and collecting a different set of brain waves.“Even if that was stolen, you could just cancel it and record one to something else”, says professor Laszlo.

Laszlo and her team have shown that their system can be 100 per cent accurate. So one of the most difficult parts of making the system practical already has been overcome. Now, they’re spending much time recording accurate brainprints with as few as three electrodes, which could make recording in the future as easy as wearing a pair of special glasses. They’re also working with cheaper materials and different methods to see if they can bring the cost down.

9 .     1     You probably think you will never be a top student. This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here’s how:

Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying.     2     A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.

Find a good place to study. Look around the house for an area suitable for study. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject.

Make good use of your time in class.     3     Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.

Study regularly. When you get home from school, go over your notes, review the important points that your teacher is going to discuss the next day, and read that material.     4     If you do these things regularly, the material will become more meaningful, and you’ll remember it longer.

Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. This helps you remember your new knowledge. The world won’t end if you don’t pass a test, so don’t be over worried.

    5     You will probably discover many others after you have tried these.

A．Take advantage of class time to listen to what the teacher says.

B．Don’t forget to set aside enough time for entertainment.

C．There are other methods that might help you with your studying.

D．Maybe you are an average student.

E．No one can become a top student unless he or she works hard.

F．Make full use of class time to take notes of everything the teacher says in class.

G．This will help you understand the next class.

10 . Twelve-year-old Catherine has a lot of friends—632, actually, if you count up her online friends. And she spends a lot of time with them.

But is it possible that Catherine’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.

Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not words with friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.

Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platform.

In fact, in many ways, online communication can make friendships stronger. “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.

Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual world, we will have little time for our real-world friendships,” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need anyone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.
