How to get teenagers to read

Getting teenagers to read sounds like a hard task. 【1】Here is some advice on how to get your teenagers to read.

【2】

You could look at their school homework timetable and work out which evening they have the least amount of work to do. Make sure that your teenager is not going to an out-of-school club that evening.

Buy your teenagers a new set of books.

Research the book lists for teenagers. The Chaos Walking Trilogy and The Hitchhikers Guide to the Galaxy are suited for both boys and girls. If your teenager will never sit down to read a book, consider buying them an electronic reader like an Amazon Kindle Paperwhite to encourage them to read. Make sure that the electronic（电子的）reader you buy can only be used to read. 【3】

Seize opportunities.

If they seem unimpressed then whenever you see them not doing anything constructive, encourage them to pick up one of the books you bought. If they say they don’t want the book then take them out to buy some in a bookstore. 【4】

Consider punishments.

【5】 This doesn’t work for everyone but some people find that when your teenager messes（脏乱）up, you can tell them to go to their room and read. They might start to really enjoy the book.

A. Don’t be afraid of wasting money.

B. Electronic readers are harmful to teenagers’ eyesight.

C. Figure out what time is best for your teenager to read.

D. If they still refuse then you could use reading /span>as a punishment.

E. But getting them to pick up a book is a lot easier than it sounds.

F. You’re sure to pick out a book that they really want to read there.

G. You know they could pretend to read and actually play video games.

【题目】Passage 3（2017·新课标卷III）

Lots of people find it hard to get up in the morning, and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock. 1 Here’s how to make one.

● 2 In order to make a change, you need to decide why it’s important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reasons, tell your family or roommates about the change you want to make.

● Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags. 3 That’s a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.

● Keep your sleep/wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found. 4

● Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record. 5 If not, take another look at other methods you could try.

A. Get a sleep specialist.

B. Find the right motivation.

C. A better plan for sleep can help.

E. If the steps you take are working, keep it up.

F. Stick to your set bedtime and wake-up time, no matter the day.

G. Reconsider the 15 minutes you spend in line at the cafe to get coffee.
