Today,kids have more worries and face more pressures than ever before. Here are a few tips to help your child focus on and do well in school.

●Create a personal schedule

Recording everything that must be done on a calendar or “to do” list will help him to keep track of important dates and deadlines. If he keeps it in a visible place he will have no problem acknowledging upcoming events and will be better able to plan how and where to spend his time.

●Watch the clock

 2  I also recommend setting his clock or watch five minutes ahead since it's always easy to run late. When it comes to something like catching a bus,just five minutes can make a significant difference.

●Focus

He should train himself to be able to concentrate alone on one specific task. This is much easier in a noise­free environment. No TV or radio should be on to distract him.

 3 

Lack of sleep is proven to harm us physically. The more sleep we get,the more alert we are. We thus have more energy to handle life's daily tasks. The average adult needs at least six hours of sleep a night and the average child needs at least eight.

●Stay in shape

Through spending time outdoors or playing sports with friends,he can “blow off some steam” so to speak,as well as re­energize. 4 

●Talk through your problems

Be able to share his concerns with you.  5  If you make it clear that you understand him and are willing to help,not only will you contribute to his emotional health but you'll help build an open and honest relationship as well.

A.Sharing feelings often makes them easier to deal with.

B.Help your child work better to realize his aim.

C.Setting an alarm for the morning is a must.

D.Get enough sleep.

E.Help your child do better in school.

F.Encourage your child to be positive.

G.Encourage him to get outside.

阅读下面短文,并根据短文后的要求答题(请注意问题后的字数要求)。

[1]Global difference in intelligence is a sensitive topic, long filled with a large number of different opinions. But recent data has indeed shown cognitive (认知的) ability to be higher in some countries than in others. What's more, IQ scores have risen as nations develop—a phenomenon known as the "Flynn effect". Many causes have been put forward for both the intelligence difference and the Flynn effect, including education, income, and even non-agricultural labor. Now, a new study from researchers at the University of New Mexico offers another interesting theory: intelligence may be linked to infectious-disease rates.

  [2]The brain, say author Christopher Eppig and his colleagues, is the "most costly organ in the human body". Brainpower consumes almost up to 90 percent of a newborn's energy. It's clear that if something affects energy intake while the brain is growing, the impact could be long and serious. And for vast parts of the globe, the biggest threat to a child's body—and therefore brain—is parasitic (由寄生虫引起的) infection. These illnesses threaten brain development________________. They can directly attack live tissue, which the body must then try every means to replace. They can invade the digestive pipe and block nutritional intake. They can rob the body's cells for their own reproduction. And then there's the energy channeled (输送) to the immune system to fight the infection.

  [3]Using data on national "disease burdens" (life years lost due to infectious diseases) and average intelligence scores, the authors found they are closely associated. The countries with the lowest average IQ scores have the highest disease burdens without exception. On the contrary, nations with low disease burdens top the IQ list.

  [4]If the study holds water, it could be revolutionary for our understanding of the still-confusing variation in national intelligence scores.

1.What is the main idea of the text?(no more than 10 words)________________________

2.Complete the following statement with proper words.(no more than 4 words)

  Those countries that have the ________________ are always at the bottom of the  IQ list.

3.Fill in the blank in Paragraph 2 with proper words.(no more than 5 words)

___________                                                                

4.What can cause intelligence difference?(no more than 8 words)

  ________________________________________________________________________

5.What does the word "they" (Line 2, Paragraph 3) probably refer to?(no more than 8 words)

________________________________________________________________________
