题目内容

For a year and half, kids sent hurtful messages like “You are ugly.” or “Why are you still alive?” to Rebecca Sedwick. In 2013, Rebecca, then 12, couldn’t stand it anymore. She took her own life near her home in Florida. Soon afterward, Trisha Prabhu read about the story. “I was surprised and heart-broken,” said Trisha, now 15, who is from Naperville, Illinois, “I know that I had to do something to stop this from ever happening again.”

Trisha did some research. Studies show that one fourth to half of all teens in the US have been cyberbullied (网络欺凌). Experts say that if you are ever bullied online, you should tell a trusted adult. Tell the cyberbully to stop, and prevent him or her from contacting you again. Print and save messages to share with the police. This is good advice, agrees Trisha. But these methods all take place after the bullying has already happened. Trisha had a different idea. Why not teach cyberbullies to stop before they post these messages?

Trisha’s research won awards, including a prize in the Google Science Fair. Then, Tresah built the ReThink app (应用软件). It is programmed to recognize words or phrases that could be hurtful. When that happens, different warning messages come out. “Don’t say things that you may regret later!” says one message. Others ask, “Are you sure you want to say this?” and “Are these words really yours?”

Now Trisha is working on a version(版本) of ReThink for computers. “I am a big dreamer,” she says. “I want to stop cyberbullying before the hurt is done.”

1.What do we know about Rebecca Sedwick?

A. She was one of Trisha's best friends.

B. She sent hurtful messages to others.

C. She ended her life at the age of 12.

D. She went to Florida to study further.

2.What is Trisha’s suggestion for stopping cyberbullying?

A. Stop talking with the cyberbully.

B. Stop the messages before they are sent.

C. Turn to your parents or close friends

D. Show the messages to the police at once.

3.What is the third paragraph mainly about?

A. People's attitudes to the ReThink app.

B. Trisha's research on cyberbullying.

C. How the ReThink app works.

D. The Google Science Fair.

4.Which of the following can best describe Trisha?

A. Honest and careful. B. Helpful and clever.

C. Proud and impolite. D. Strange and impatient.

Scientists announced that they had found the gravitational waves（引力波）that confirmed a prediction made by Albert Einstein a century ago.The discovery,made with the Laser Interferometer Gravitational—Wave Observatory, known as LIGO,is the milestone（里程碑）in a decades—long search for signs of this phenomenon."The discovery will open a new window onto the universe,"said David Reitze,executive director of LIGO.

Since humans first watched skyward,we have relied on light of all wavelengths to describe the universe.The light that could be seen first showed the starry heavens,while infrared（红外线的）waves allowed us to see older and more distant stars.

But now,researchers will be able to sense the universe in a whole new way: with their "ears"."We can hear gravitational waves.We can hear the universe,"Gabriela Gonzalez,LIGO's spokeswoman at Louisiana State University,said."That's one of the beautiful things about this: We are not only going to be seeing the universe,we are going to be listening to it."

Gravitational waves,which Einstein predicted as part of his general theory of relativity,occur as objects accelerate or decelerate through space,much the way a boat moving on a lake sends waves across the water's surface. But they're so tiny that until now it's been nearly impossible to find them,even those caused by something as large as a planet moving around the sun.

To pick up this signal,scientists have to look for violent events in the universe.This particular signal appears to have been caused by a collision.That occurred about 1.3 billion years ago between two black holes,holding 29 and 36 solar masses（太阳质量）.

Fiona Harrison,chair of Caltesh's division of physics,mathematics and astronomy,guessed that hundreds of new events would be found over the next few years,allowing scientists to perform a range of different types of studies. "There are probably many events we haven't dreamed of and this is just the beginning,"she said.

1.Why did Gabriela Gonzalez think LIGO's discovery important?

A. It confirmed Einstein's scientific prediction.

B. It allowed scientists to see more distant stars.

C. It changed traditional ideas about the universe.

D. It offered different way to study the universe.

2.It's hard to find gravitational waves because they .

A. are too far to be felt

B. are too weak to be observed

C. are disturbed bu other planets

D. disappear soon after they happen

3.Which of the following would scientists consider to be a violent event?

A. Hearing the universe.

B. Searching for infrared waves.

C. A collision between black waves.

D. A planet moving around the sun.

4.It can be concluded that .

A. gravitational waves also exist in objects at rest

B. there's a long way to go in studying the universe.

C. gravitational waves show the beginning of the universe.

D. scientists began studying gravitational waves in recent years.

The current Ebola (埃博拉病毒)outbreak in western and central Africa has infected at least 3,069 people, including 1,552 dead, making it the largest outbreak in history. Ebola is a deadly virus-about 60 percent of people infected with it have died.

How is Ebola doing its harm?

When a person becomes infected with Ebola, the virus damages the body’s immune (免疫的)cells, which defend against infection, said a researcher at Lancaster University. But if a person’s immune system can stand up to this attack, then he is more likely to survive the disease.

The patients that survive it best are those who don’t get such a bad disadvantage in immune system. But if the body isn’t able to get rid of this attack, then the immune system becomes less able to regulate(调节) itself. This means the immune system is more likely to run out of control, leading to a drop in blood pressure, multi-organ failure and eventually death.

What are the common symptoms of the disease?

Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body.

How to prevent the spread of Ebola?

Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient.

We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates(灵长类). If you’re in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side.

Wear protective medical clothing if you’re around infected patients. Extreme caution is necessary. Hospital workers must use masks, gloves, goggles, and gowns, which needed to be worn at all times if you’re around infected patients.

How Do People Survive Ebola?

Doctors don’t know for certain who will survive Ebola, and there is no specific treatment or cure for the disease. Although in the minority, some people do recover from infection.

Our suggestions include:

Maintain your electrolytes(电解质) and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you’re feeling pain.

1.Ebola causes the death of a human being by .

A. attacking him with high fever B. regulating his immune system

C. damaging his immune cells D. harming all his organs directly

2.What is NOT mentioned as the symptom of Ebola?

A. Fever and chills B. Swallowing difficulty

C. Lack of appetite D. High blood pressure

3.In order not to be infected by Ebola, we should .

A. have the clothing of the infected cleaned

B. avoid eating wild animals like monkeys

C. not travel to Africa, America or Europe

D. stay at home without going anywhere

4.It is true that .

A. a certain number of people survive Ebola

B. human has found a special cure for Ebola

C. oxygen can save infected people’s lives

D. low blood pressure is surely caused by Ebola

A safari park is a park in which wild animals are kept. They are mainly located in east or central Africa. They often occupy a very wild area, with mountains and rivers. To visit the park and look at the animals, people have to drive around — in a car for a few of hours because the park is huge.In south Africa there is a safari park, which contains all sorts of wild animals like lions, elephants, rhinoceroses(犀牛), zebras, wild pigs, deer and giraffes.

There is a wild road leading through the park, but nobody is permitted to walk on the road. Anyone traveling in the park has to go in a car because wild animals may fiercely attack people. From the car he may see almost every types of African wildlife. Some of these are getting scarce(稀有的) because people kill them for various reasons. For example, rhinoceroses are killed for their horns(角), which are used in traditional Chinese medicines for colds and headaches. Perhaps they will be seen only in museums and books one day.

Travelers may purchase food for the animals. They can feed them when they tour the park. Of course, they should not feed them in a close distance because the wild animals may attack people. In addition, they should only give proper food to the animals.

A traveler may carry a gun with him in his journey. The gun is given to him by the government. However, it is not used for hunting. In fact, a seal is fixed to it.
