【題目】Two brothers decided to dig a deep hole behind their house. As they were working, a couple of older boys stopped by to watch.

“What are you doing?” asked one of the visitors.

“We plan to dig a hole all the way through the earth!” one of the brothers said excitedly.

The older boys began to laugh, telling the younger ones that digging a hole all the way through the earth was impossible. After a long silence, one of the diggers picked up a jar full of spiders, worms and all kinds of other insects. He removed the lid and showed the wonderful contents to the scoffing(嘲笑)visitors. Then he said quietly and confidently, “Even if we don’t dig all the way through the earth, look what we found along the way!”

Their goal was far too ambitious（有野心的）, but it did cause them to dig. And that is what a goal is for — to cause us to move in the direction we have chosen; in other words, to set us to digging!

But not every goal will be fully achieved. Not every job will end successfully. Not every relationship will endure(長久持續(xù)). Not every dream will be realized. But when you fall short of your aim, perhaps you can say, “Yes, but look at what I found along the way! Look at the wonderful things which have come into my life because I tried to do something!”

It is in the digging that life is lived. And I believe it is joy in the journey, in the end, that truly matters.

【1】Which of the following is NOT the reason why the older boys laughed at the two brothers?

A. The two brothers only dug out a lot of insects

B. The two brothers lacked knowledge of the earth.

C. The two brothers were foolish.

D. The two brothers had a far too ambitious goal.

【2】What does the underlined part “when you fall short of your aim” probably mean?

A. When you are shorter than you expected

B. When you have less than the amount than you wanted

C. When you fail to obtain（得到）what you expected

D. When you miss the target you are aiming at

【3】The passage is written to _____.

A. tell readers a story

B. teach readers how to set a goal

C. praise the two brothers

D. teach readers a lesson

【4】Which would be the best title for the passage?

A. Dig a Hole Through the Earth

B. Joy in the Journey

C. Realize Your Goal

D. Don’t Laugh at Others

【題目】2014 saw that the Ebola virus reappeared in Guinea and soon spread into neighbouring Liberia and Sierra Leone, killing over 7,800 people by the new year of 2015. It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc.

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, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 out- break, and is believed to be attacking Guinea.

Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids of the infected animals. Once infected, a human becomes a carrier of the deadly virus.

Unfortunately, there are no disease - specific treatments for Ebola. Health - care workers only supply the infected people with physiological saline（生理鹽水）to keep them in good condition. Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa. 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 infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.

What’s worse, 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. It is feared that the disease may spread throughout west African countries. For every country, a strong health system can decrease the risk of health attack and lessen the impact of Ebola.

【1】What is the function of the first paragraph in the whole passage?

A. To arouse the reader’s concern.

B. To summarize the whole passage.

C. To give a detailed description of Ebola.

D. To introduce the theme of the whole passage.

【2】What can we infer about the Ebola virus?

A. It has caused a panic in many countries.

B. It is the most dangerous virus in the world.

C. A strong health system is important to fight against Ebola.

D. Anyone who was infected Ebola will die.

【3】Paragraph 3 mainly tells us _________.

A. What the Ebola virus is

B. How the Ebola virus spreads

C. How the Ebola virus is treated

D. How the Ebola virus affects the life

【4】Which of the following is true?

A. There are no effective drugs to treat Ebola by far.

B. Ebola is now very common in Guinea.

C. Those with a fever must be infected by Ebola.

D. Females are easier to be infected by Ebola.

【題目】Mozart was a great man born with a given talent. He was writing songs at the age of five and performing before the queen by the time he was six years old. Early on, Mozart realized what his talents were, practiced or honed what he was born to do and used his natural abilities to create amazing pieces of music.

Mozart was not the first to be born with natural talents and he wasn't the last. We all have them. We only need to discover what they are and use them to the best of our abilities. You have been given amazing gifts that are meant to be shared with the world. Your job is to find out what those talents are and master them.

Finding your natural talents may not be an easy task. Perhaps your parents except fewer wouldn't approve of （贊成）your artistic ability to paint or sing, because they want you to be a successful doctor or lawyer. Maybe your gift wouldn't seem to have the ability to bring the kind of wealth you hope. These may be excuses; it's up to you. Have you ever noticed that when you engage in an activity in which you are naturally talented, you feel active and excited? That's a sign that these are the things you should do. Discover your brilliance （才華）in life and practice, practice, practice.

Look at the world's greatest athletes. They practice what they're naturally good at, and what they love. You don't see Jordan sitting trying to study DNA. If that was something he was talented at, that's what he would be doing. But it's not. He's a brilliant athlete. He sticks to what he does best and he realizes his dream.

There are only two steps to success-discover your brilliance and perfect it.

【1】In the writer's opinion Mozart's success lies in __________.

A. his great given talent

B. making good use of his natural talent

C. learning from others

D. his favorable conditions

A. To do something repeatedly to improve one's skill.

B. To find out what one is always good at doing.

【3】In Paragraph 4 the writer advises us to __________.
