Homework

Do maths problems 15 through 25. State the different forms of the verbs on page 50 of your French workbook. Read pages 12 through 20 of the Shakespeare play, and don’t forget to fill in the missing chemical symbols on the worksheet.

Sound like a list of your homework for the next few nights — or maybe even just for tonight? 1.It’s your teachers’ way of evaluating how much you understand what’s going on in class. And it helps strengthen important concepts. Here are some tips on how to do your homework.

2.It’s inviting to start with the easy things to get them out of the way. However, you’ll have the most energy and focus when you begin, so it’s best to use this mental power on the subjects that are most challenging. Later, when you’re more tired, you can focus on the simpler things. If you get stuck on a problem, try to figure it out as well as you can — but don’t spend too much time on it because this can mess up your homework schedule for the rest of the night. 3.But don’t pick someone whom you’ll be up all night chatting with, or you’ll never get it done!

Most people’s attention spans aren’t very long, so take some breaks while doing your homework. Sitting for too long without relaxing will make you less productive than if you stop every so often. Taking a 15-minute break every hour is a good idea for most people.4.

Once your homework is done, you can check over it if you have extra time. Be sure to put it safely away in your backpack—there’s nothing worse than having a completed assignment that you can’t find the next morning or that gets ruined by a careless brother or sister. 5.Now you’re free to hang out.A. Luckily, you can do a few things to do less homework.

B. Homework is a major part of going to school.C. No one is expected to stay long, and people have very different learning styles.

D. If you need to, ask an adult for help or call or email a classmate for advice.

E. But if you’re really concentrating, wait until it's a good time to stop.F. And no teacher still believes that “chewed by the dog” line—even when it's true!

G. When you start your homework, deal with the hardest tasks first.

You're rushing to get out of the door for a meeting, but you just can't seem to find your car keys. Or you've got tickets booked for a Caribbean cruise(坐船旅行) , but your passport disappeared. Or maybe you've just come back from a grocery store tour and realized…Hey, did I leave my baby in the checkout line?

Ok, you've probably never gone to the extremes of our last example (we hope), but most of us experience slip - ups like these on a daily basis. No matter how smart you may be, it doesn't mean your brain won't turn to Swiss cheese every so often, and no amount of e-mail reminders can help you remember where you left your TV remote or lucky penny.

But now, there is a new pair of eyeglasses that can help to find all those little things you know must be around somewhere :  Let's call it Vision 2.0.

The new glasses, which are being developed in a Japanese lab under the code name Smart Goggles,are similar to a Google search engine for your eyes. The high - tech glasses come with a camera that records everything you see on a daily basis, and boast built - in object recognition software that allows them to keep track of whatever comes across their field of vision. If you've got a collection of art sculptures that the camera can't recognize immediately, no problem :  Just say the name of each item,  and the glasses will memorize them right away.

The Smart Goggles' superb tracking abilities mean that whenever you're looking for your keys, your overdue library book, or yes, even your baby, all you have to do is to say the word and the Goggles' camera will show you the last time your desired object appeared on screen, telling exactly where you'll be able to find it.

Though the glasses are still too big for general use, the research team in Japan believes that they'll be able to make the modem glasses smaller to the size of normal glasses in the near future, making them the perfect new accessory for yourself or any other absent - minded Professor you know.

With these intelligent designs, you'll never lose anything again. Except maybe your glasses.
