We’ve certainly seen a dog nursing a wound, or a deer calling out in pain. But many animals suffer in silence. The most silent sufferers in the animal world may be fish.

Do fish feel pain? A new study from the University of Liverpool has found that fish feel pain in a way that’s “strikingly similar” to humans. For the study, Lynne Sneddon, from the university’s Institute of Integrative Biology, reviewed the existing body of research-98 studies in all-and concluded that they feel pain just as sharply as we do.

“When subject to a potentially painful event, fish show changes in behavior such as stopping feeding and reduced activity, which are prevented when a pain-relieving drug is provided. In fact, like us, they breathe heavily and stop eating when they’re hurting. They will even rub the part of their body that aches.” Sneddon notes in a university release.

To understand pain in other species, scientists look at nociceptors, which send signals to the brain when the body is being damaged. Humans have them throughout their skin, bones and muscles. Nociceptors have also been found in many other species, including even those tiny fruit flies. Fish have the same means to detect pain signals and the equipment to receive them.

Besides, the fishermen’s opinion that fish feel no pain just doesn’t add up from an evolutionary view. Pain is an efficient messenger that tells us that we’ve got a problem. An animal that can’t feel it won’t get that memo(备忘录), even if it hurts itself.

“If we accept fish experience pain, then this has great significance for how we treat them,” Sneddon says. “Care should be taken when handling fish to avoid damaging their sensitive skin and they should be humanely caught and killed.”

1.What will a fish do when its lips get hurt?

A.It might rub its lips. B.It will keep its mouth open.

C.It will swim around like crazy. D.It will keep eating to forget pain.

2.What is the significance of the study according to Sneddon?

A.People will treat fish in a kinder way.

B.People can understand evolution better.

C.People can develop more drugs to save fish.

D.People will think of more ways to catch fish.

3.What does the underlined part “add up” probably mean?

A.disappear B.put forward C.make sense D.happen

That “Monday morning feeling” could be a crushing pain in the chest which leaves you sweating and gasping for breath. Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break.

The risk of having a heart attack on any given day should be one in seven, but a six-year study helped by researchers at the Free University of Berlin of more than 2,600 Germans showed that the average person had a 20 percent higher chance of having a heart attack on a Monday than on any other day.

Working Germans are particularly not protected against attack, with a 33 percent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day.

A study of 11,000 Italians proved 8 am on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewer heart attacks in both countries.

The findings could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr Stefan Willich of the Free University. “We know a lot about long-term risk factors such as smoking and cholesterol（胆固醇）but we don’t know what actually causes heart attacks, so we can’t give clear advice on how to prevent them,” he said.

Monday mornings have a double helping of stress for the working body as it makes a rapid change from sleep to activity, and from the relaxing weekend to the pressures of work.

“When people get up, their blood pressure and heart rate go up and there are hormonal（内分泌）changes in their bodies,” Willich explained. “All these things can have an unfavourable effect in the blood system and increase the risk of a clot（血凝块）in the arteries（动脉）which will cause a heart attack.”

“When people return to work after a weekend off, the pace of their life changes. They have a higher workload, more stress, more anger and more physical activity,” said Willich.

1.．Monday morning feeling, as this passage shows,         .

A. is not so serious as people thought

B. is harmful to working people in Germany and Italy

C. is the first killer in Germany and Italy.

D. is created by researchers in Germany and Italy

2.．To protect people from suffering from heart attack, doctors have paid much attention to     .

A. people’s working time          B. people’s living place

C. people’s diet and lifestyle    D. people’s nationalities

3.．It can be learned from this passage that heart attack has nothing to do with      .

A. blood pressure     B. heart rate    C. hormonal changes     D. blood group

4.．If the researchers give us some advice to avoid Monday morning feeling, what might it be?

A. Stop working on Monday             B. Create a pleasant working environment

C. Get up late on Monday morning     D. Go to work with a doctor

5..Which of the following is true according to the passage?

A. The risk of having heart attacks on Monday mornings is the same as on any other day of the week to non-workers

B.33% of the Germans have heart diseases, therefore heart attacks are more common in Germany than in any other country.

C.20%of the Italians appear to have higher possibility of having heart attacks.

D. Non-smokers are more likely to have heart attacks on Sundays.

This year’s flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn’t yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫 苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.

The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms　 have　 less　 to　 do　 with　 the　 virus　 itself　 than　 with　 your　 immune( 免 疫 的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.

The virus usually enters through your mouth, typically by way of your hands . But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.

The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader , the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates a serious inflammation( 炎 症 ) throughout the body. But the worst is still to come.

Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

1.What can we infer from Paragraph 1?

A.All the vaccine is not effective.

B.No one can avoid catching this year's flu.

C.This year's flu is the most serious one in recent years.

D.Public health officials have to use a gun when necessary.

2.Why many parts of your body suffer while you're recovering from a flu?

A.Because recovery from illness is painful.

B.Because your immune system is working against your defense system.

C.Because your body is fighting hard against the flu.

D.Because the influenza virus attacks your nose, throat and other parts.

3.The underlined word “fun” in Paragraph 4 can be replaced by　 　　 .

A.joy B.battle

C.action D.program

4.What's the main idea of Paragraph 4?

A.The fight between innate immune system and the adaptive.

B.The categories of immune system.

C.The way immune system works.

D.The process of the development of immune system.

Scott Ward didn't have any risk factors that he knew of for cancer so he ignored the lump on his neck until he couldn't ignore it anymore. Dr. Donald Doll, the doctor who treated Ward for his cancer, said, “We’re seeing more and more younger and healthier patients. They're not smokers or drinkers. It's HPV-related.” “Normally, you think of HPV (乳头瘤病毒), you think of women,” Doll added, “while it's a misconception that only women have to be concerned with cancers caused by this virus.”

Luckily, there's a vaccine (疫苗) that's been around for more than a decade that can protect against the HPV virus. If all boys and girls received it, no one would get HPV-related cancers. The HPV vaccine is best when given to children between 9 and 12 years old, before they are sexually active. But teenagers and young adults can still benefit from the vaccine.

Not everyone who gets the HPV virus develops cancer. But it is a risk factor. The agency says about 14 million people in the U.S. alone become infected with HPV each year. Yet, about half of all U.S. adolescents have not been fully vaccinated against HPV, which requires a series of three shots. The CDC says the side effects are generally short term and not serious. They can include dizziness, headache, fever, pain and etc.

Ward’s recovery was difficult. But he’s now cancer-free. Ward wishes the HPV vaccine existed when he was a teen. He says if he had kids, he would get them vaccinated. “HPV-related cancers are cancers no one needs to get.” Ward said.

1.Who should be worried about HPV-related cancers?

A.Only women. B.Everyone.

C.Younger people. D.Smokers and drinkers.

2.Which of the following statements is TRUE according to the passage?

A.The HPV vaccine is best when given to teenagers and young adults.

B.About 50% of all adults in America have not been fully vaccinated against HPV.

C.One gets cancer if he or she gets the HPV virus.

D.HPV vaccines have some side effects including dizziness, headache, and etc.

3.Why did Ward say HPV-related cancers were cancers no one needed to get in the last paragraph?

A.It is easy to recover from HPV-related cancers.

B.HPV-related cancers are not that common.

C.HPV-related cancers can be prevented by vaccination.

D.HPV vaccine existed when he was a teen.
