Have you ever felt sick to your stomach during a test? Have you ever been so worried about something that you ended up with a terrible headache?

If so, then you know what it’s like to feel stress. You’ve probably heard people say, “Wow, I’m really stressed out.” 1. But children have lots of things going on in their lives that can cause stress, too.

What is stress?

Stress is what you feel when you are worried or uncomfortable about something. This worry in your mind can make your body feel bad. You may feel angry, frustrated, scared, or afraid --- which can give you a stomachache or a headache.

What causes stress?

Plenty of things can cause stress in a child’s life. 2. Good or normal stress might show up when you’re called on in class or when you have to give a report. Have you ever gotten butterflies in your stomach or sweaty hands? Those can be signs of good stress. 3. For example, you may do a better job on your book report if the anxiety inspires you to prepare well before you get up and read it to the class.

But bad stress can happen if the stressful feelings keep going over time. You may not feel well if your parents are fighting, if a family member is sick, if you’re having problems at school, or if you’re going through anything else that makes you upset every day. 4.

Once you recognize that you’re feeling stressed, there are several things you can do. You can try talking about what’s bothering you with an adult you trust, like a parent or teacher. 5. An adult may have ideas about how to solve whatever is worrying you or making you uncomfortable.

A. This kind of stress can help you to get things done.

B. Maybe you hear adults say those kinds of things all the time.

C. Bring up what’s been on your mind and how it makes you feel.

D. Everyone experiences stress at times --- adults, teens, and even kids.

E. There are ways to reduce stress and manage the stress that’s unavoidable.

F. That kind of stress isn’t going to help you, and it can actually make you sick.

G. The trick is to remember that some types of stress are good and others are bad.

When we hear of dangerous diseases, cancer and heart disease are often what first comes to mind. Recently, a virus (病毒) called Ebola has reappeared in Guinea (a country in West Africa), killing 62 people so far. It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc, Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa.
Ebola is named after the Ebola River, where it was first discovered in 1976.There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Restoon, Bundibugyo, and Zaire.The deadliest of the five, Zaire, was responsible for the 2012 outbreak, and is believed to be attacking Guinea.
Ebola is naturally found in fruit bats (果蝠), which pass on the virus to other animals by biting or sucking on (吮吸) their blood.Humans who are suffering from the Ebola infection might have touched the bodily fluids (液体) of the infected animals.Once infected, a human becomes a carrier of the deadly virus.
Since we live in an interconnected world, where the situation in one country can affect us all, the influences of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries.Already the Guinea virus is spreading fast with a few cases spotted in Conakry — the capital of Guinea, far away from the origin of the virus.It is feared that the disease may have already reached neighboring Liberia and Sierra Leone, too.
Unfortunately, there are no disease-specific treatments for Ebola.Healthcare workers only supply the infected people with water to keep them in good condition.Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the affected.The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.
1.The news of Ebola in Guinea is mentioned to ________.
A. make a brief summary
B. introduce the topic of the text
C. compare Ebola with cancer
D. show the latest study of viruses
2.What can we learn about Ebola?
A. It is a newly discovered virus.
B. It is the most dangerous virus in the world.
C. It was named after where it first happened.
D. It could cause immediate death for anyone infected.
3.What is mainly described in Paragraph 3?
A. What the Ebola virus is.
B. The influences of Ebola.
C. The treatments for Ebola.
D. How the Ebola virus spreads.
4.Which of the following does the author probably agree with?
A. Ebola is a highly infectious virus.
B. Ebola is now very common in Guinea.
C. Those with a fever must be infected by Ebola.
D. Females are more easily to be infected by Ebola.

Lights Out at Bedtime

There are plenty of good reasons to power up a personal desktop or laptop computer in the evening — writing e-mails, chatting on social networks or making purchases over the Internet, for instance. But various studies indicate that people who stare at a PC’s bright monitor shortly before going to bed probably sleep less soundly than they would otherwise because the light seriously affects their natural wake-sleep cycle."They haven't proved it though," says Dieter Kunz, the team's director at Charite's Psychiatric Clinic in St. Hedwig's Hospital in Berlin.

Similarly, exposure to just 10 minutes of normal bathroom lighting is enough to free the sleep hormone melatonin, which regulates people's natural wake-sleep cycle and makes them sleepy at nightfall.

Ten years ago, a team of British and American researchers detected a photo-pigment(光敏色素) in the human eye that signals to the body whether it is day or night, summer or winter. The photo-pigment is especially sensitive to blue light.

"The blue light more or less tells the body, It's daytime, be awake,'" Kunz says. Monitors have a mostly cold white light content and scientists suspect the photo-pigment may react similarly to it. So the longer people look into the bright light, the more awake they become - and then sleep poorly.

A lot of people have difficulty "switching off" in the evening. About half of the women in Germany and a quarter of the men sleep poorly.

Environmental factors are only one of the possible causes. Job stress as well as personal and health concerns are also the main reasons for their sleep problems.

In addition, electronic objects' standby lights and indicator lamps can be annoying in the dark and affect sleep."Sound scientific evidence is still lacking on this matter," Kunz notes.

According to Kunz, those who cannot go without their computer in the evening should turn down the blue content if possible and lower the brightness somewhat."But nobody does that because, after all, you want to concentrate while working at the computer and the light helps the brain."
