【題目】Does a 16-year-old have the ability to change the world, benefiting hundreds of thousands of people?

Olivia Hallisey should believe so. With her invention of new Ebloa test, the girl from US has become the winner of the 2015 Google Science Fair, a yearly competition for creative teenagers who want to make a difference in the world.

Hallisey’s method asks patients to put a sample of their saliva (唾液)onto a testing card. The card changes color if the person is infected with Ebloa. Present Ebloa tests can take up to 12 hours and cost $1,000. Hallisey’s method, by contrast, can be done just in 30 minutes for about $25. Moreover, the test needn’t be put in a refrigerator thanks to the silk material Olivia used to produce the testing cards.

Hallisey started working on the test one year ago when she saw Ebloa spreading across African countries. Her research was based on looking at and using previous research and her own creative ideas.

“She deserves all the praise she’s getting for her hard work, dedication, and intelligence,” said her science teacher Andrew. “Her project is very helpful for the medical diagnosis that we need in parts of the world where Ebola is most common.”

“What affects one country affects everyone,” Hallisey told CNBC. “We have to work together to find answers to the challenges that threaten global health, our environment and our world.”

A. use a person’s saliva, which is sorted at a low temperature

B. are less time-consuming and less expensive than current tests

C. are less time-consuming but more expensive than current tests

D. show changes in the color of blood if the person is infected

【2】Which of the fo llowing statements is TRUE?

B. Olivia’s research was based on her own creative ideas.

C. Olivia set her mind on winning the 2015 Google Science Fair.

D. Olivia’s research began before the outbreak of Ebloa in Africa.

【3】What quality makes the test more convenient?

A. The material used can easily be produced in Africa.

B. The material used is easier to store in a refrigerator.

C. The material used needn’t be put in a special device.

D. The material used is common in the places where Ebloa is most comm on.

【題目】Our room was on the second floor but you could still hear the roar of the ocean and see the stars at night. I used to take long walks along the water. The food in town was wonderful and the people were very friendly. The area was very quiet and peaceful, and fairly deserted.

The last evening of our vacation, however, we all heard strange footsteps following closely behind us as we were walking up to our room in the holiday centre. We turned around and noticed a fairly young man moving very rapidly across the beach and getting closer to us. He was tall and wore a baseball cap. We couldn’t see his face and he was approaching us very rapidly. The man’s actions made my dad very nervous. Dad warned us that we’d better try to make it to our hotel room as quickly as possible. I didn’t like my dad’s voice; I could hear fear in it. It was late and we were all alone. We didn’t have any cell phones on us. I never saw Dad as worried as he was then and I knew that something was terribly wrong. The sense of fear started to overwhelm Mom and me. We had had such a good time in town. Now, the night was rapidly turning into a dangerous situation.

We could hear the man’s footsteps getting closer. Dad’s face was almost pale. The so-called intruder (侵入者) had moved nearer and nearer when all of a sudden, the nearby vending (自動(dòng)販賣) machine started going crazy and spitting out cans of soda! The noise actually scared the intruder and he ran out of sight. My parents were shaking, but we all turned around to see who had put money into the vending machine downstairs, and actually saved us, but no one was around at all. Not a soul.

It’s one vacation I will never forget.

【1】Where did the author spend her vacation?

A. Near a lake.B. At the seaside.

C. In a village.D. In a mountain.

【3】What helped them get out of the trouble?

A. Their quick action.

B. Other people’s kind help.

【題目】Flight cancellations(取消) and loss of luggage can ruin even the best-planned holiday. The key to a stress-free trip is having a backup plan.

Fly non-stop. The worst problems involve connections, so it is important to take non-stop flights whenever possible. If you do have to make a connection, try to route through a southern city, where snowstorms and de-icing delays will be less likely. Always allow at least two to three hours for flight connections.

Check the weather. Check the weather in your connecting city, not just the arrival and departure city. If your departure flight is cancelled because of weather, you can go home or back to your hotel. Airlines promise to get you on the next available flight, not the next flight. That could be several days later on a sold-out holiday weekend.

Go early. The earlier in the day you fly, the better your chance of getting rebooked the same day after a missed connection. It will also put you ahead of stranded(滯留的) passengers who arrive later.

Rebook immediately. As soon as your flight is delayed or cancelled, get on the phone and rebook your flight instead of waiting at the ticket counter. If your rebooking is delayed, call or ask your travel agent to find a seat on another carrier, and then ask your original carrier to endorse your ticket to the new airline. Airlines are not required to do this but often do. Learn more at www. dot. gov/ airconsumer/ fly-rights.

Ship bags. A few days before your flight, ship suitcases or holiday gifts to your destination by a documented express service. It’s preferable to losing bags because of re-routed flights and sometimes cheaper than paying airline overweight bag fees.

Know your rights. Airlines are not required to compensate passengers for delayed or cancelled flights, but it never hurts to ask for goodwill vouchers(折扣) for meals, taxis or a room.

【1】When making a flight connection, it’s common that you’ll___________.

A. stop in the south B. choose a good city without snowstorm

C. be trapped in the storm D. wait for two or three hours

【2】The suggested way for you to rebook your flight is___________.

A. through the phone B. by waiting at the ticket counter

C. by changing another airline D. by surfing the Internet

【3】The underlined word “compensate” in the last paragraph can be replaced by “___________”.

A. pay B. ask C. host D. treat

【4】What’s the best title of the passage?

A. The Worst Problem in the Trip.

B. The Preparation Before the Flight Trip.

C. How to Book the Plane Ticket.

D. How to Plan the Holiday.

They Just Can't Help It

My theory is that the female brain is mainly built for empathy — the ability to understand other people — and that the male brain is mainly built for building systems. __【1】_ For example, women are more likely to read magazines on fashion and parenting, while men will choose magazines that feature computers and sport.

You may think that these preferences are influenced by the way people are taught to behave when they are growing up. However, this is not the case. A new study carried out at Cambridge University shows that newborn girls look longer at a face, and newborn boys look longer at a mobile. __【2】_ It has also been observed (that girls are better at noticing signs of changes in other people's feelings. Boys, however, seem to enjoy building toy towers and playing with toys which have clear functions. __【3】_ People whose jobs are in the construction industries are almost male. Math and engineering, which require high levels of systems-thinking, are also male-chosen disciplines. Why do men and women have the difference? Actually women have four times as many brain neurons (神經(jīng)) that connect the right and left part of their brains. Because of it, women have a better ability to multitask than men. __【4】_ Men tend to focus on a limited number of problems at a time. They will separate themselves from problems and view tasks as independent from one another.

Some people may worry that I am suggesting one gender (性別) is better than the other, but this is not the case. My theory says that males and females differ in the kinds of things that they find easy, but that both genders have their strengths and weaknesses. __【5】_ It is not true. The study simply looks at males and females as two groups, and asks what differences exist, and why they are there.

A. Generally speaking, there are clear differences.

B. Their preference for building systems may change over time.

C. You can see the same kind of pattern in the adult workplace.

D. They will consider many sources of information at the same time.

E. It is important to stress that the female brain may be built more for empathy.

F. That suggests certain differences between male and female brains are biological.

G. Others may think the theory creates a belief of what a particular type of person is like.

Being a veterinarian(獸醫(yī)), I had to examine a ten-year-old Irish Wolfhound named Belker. The dog’s owners, Ron, his wife Lisa, and their boy Shane, loved Belker very much.

I examined Belker and found him 【1】 (die) of cancer. I told the family we couldn’t do 【2】 for Belker, and offered to perform the euthanasia(安樂死) procedure in their home.

As we made arrangements, Ron and Lisa told me they thought 【3】 would be good for six-year-old Shane to watch. They felt Shane might learn something.

The next day, Belker’s family surrounded him. Shane seemed so calm, petting(拍) the old dog for the last time, that I wondered if he understood 【4】 was happening. Within a few minutes, Belker slipped 【5】 (peaceful) away.

The little boy seemed to accept it without any difficulty. We sat together after Belker’s death, 【6】 (wonder) why animal lives are shorter than human lives. Shane, having listened quietly, said, “I know 【7】 .”

【8】 (surprise), we all turned to him. What he said next amazed me. It has changed my life.

He said, “People are born so that they can learn how to live 【9】 good life—like loving everybody all the time and being nice, right?”

The six-year-old boy continued, “Well, dogs already know how to do that, 【10】 they don’t have to stay as long.”

【題目】The other day I heard a few local musicians talking:

“I hate all the terrible pianos in this town. I hate that rubbish they play on the radio. They can’t even understand a bit of music.”

“I’m never playing in that club again. Too many drunks and nobody listens to us.”

But, one younger musician said, “There are a few clubs that book my band a few nights a month, and I’m trying to find other places to play. I’m also looking to book a few summer festivals this year.”

I’ve heard that you are the average of the five people whom you spend the most time with, or to put it another way, you are who your friends are.

Attitudes are important. Whether they’re positive or negative, they’re rubbing off on you. If you’re around people who complain about lack of work and about other musicians, or blame others, and you play the role of victim, chances are you will start to as well. So it’s time to take a look at the people you call “friends”.

This is an easy exercise: Make a list of the people who you hang out with, and simply stop spending time with the negative people on your list. Set a new standard for yourself and don’t become friends with people who fall below that standard.

Keep successful people around you and your own chances for success will be much better. Ask them how they do it. Ask if they will help you get the work you’re looking for, or maybe give you some advice to help you on your career path.

【1】Which of the following would be the best title for this passage?

A. A friend in need is a friend indeed

B. How to make friendship last for ever

C. You are who your friends are

D. Friends are the most important in one’s success

【2】The musicians’ words at the beginning are written mainly to show ________.

A. the musicians’ living conditions are quite poor

B. people have poor taste in music

C. people have different attitudes towards the same thing

D. young people have greater chances of succeeding

【3】By taking the exercise mentioned in Paragraph 7(underlined), you can ________.

A. improve a lot in making more friends

B. come to the right way of making friends

C. develop a better relationship with your friends

D. arrange the time with your friends properly

【4】The passage is mainly written for ________.

A. musicians B. managers

C. negative people D. people wanting to succeed
