【題目】Early risers are most likely to be healthy, wealthy and wise, according to the old saying. But those who are early to bed and early to rise do not always have advantages, researchers say. They have found that night owls（夜貓子） are generally brighter and wealthier than those who are able to get up early in the morning.

Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late showed the kind of intelligence to find good jobs and earn much money. Larks or “morning people”, however, often get better exam results, possibly because lessons are held at the wrong time of day for night owls.

The researchers examined the habits and body clocks of the young people to determine whether they liked to stay up late and sleep later in the morning, or preferred to go to bed early and were at their best state in the morning. School performance and problem solving ability, were judged and test grades in the major subjects were also taken into consideration.

Jim Horne, professor of psychophysiology at Loughborough University, said: “Evening types tend（傾向） to be the more creative types, the poets, artists and inventors, while the morning types are considered to be civil servants and accountants（會(huì)計(jì)）. ”

A．morning people will probably find good jobs and earn a lot

A．they go to bed by 10p.m. regularly

【題目】Your teen is falling asleep in class

Teens have a busy morning schedule as they need to wake up and get moving very early in order to catch a bus and get to school by the required time. This means teens need to get their rest the night before or they will be too tired to learn anything at school. 【1】

When a teen falls asleep in class, two things happen: he/she misses what is being taught and he/she loses the respect of the teacher. He/She may also receive a consequence from the school, depending on the classroom discipline policy. 【2】

To prevent your teen from being sleepy in class, try these three tips:

* Set a time for “l(fā)ights out” on school nights. This is never be any later than 10 p. m. and preferably 9 p.m. 【3】 Soft music can be on and used to help calm your teen.

* Help your teen develop a nighttime routine that involves activities that slow them down for the end of the day. 【4】 Turning off the computer and disconnecting from friends and the excitement of the day an hour before bedtime will also help your teen relax.

* 【5】 This will reinforce （增強(qiáng)）what it feels like to be rested and capable of accomplishing what he/she wants.

A. What’s worse, they may even fall asleep in class.

B. Taking a bath and reading are two activities that work well.

C. Set a good example and show him/her your love for learning.

D. Point out the positives after your teen has had a good night’s rest.

E. All of these things affect your teen’s academic success and can be avoided.

F. “Lights out” means the computer, television, lights and cell phone should be off.

G. While your teen keeps his/her goals in line with your expectations, he/she may have his/her own goals.
