It must have taken a great prehistoric thinker to imagine two thin slices of log connected, at their centers by a string stick. This would roll along just 【9】 the logs did, yet be much lighter and easier 【10】 (handle). Thus the wheel and axle came into being and with them the first carts.

【題目】When I was 5, my father worked the night shift as a nurse in a hospital. He was always carrying his stethoscope (聽(tīng)診器) so naturally, so I called him “Dr. Saldivar” while I pressed his stethoscope against his chest. But my father, as a humble man, was always correcting me: “I am not a doctor, son, but you can be one.” I grew up feeling like I had no limits because of moments like this, which has helped me take risks personally and professionally in spite of the hardships I had to endure.

Being born to Mexican immigrants meant that my parents had to work very hard to provide for my family and I had to learn to struggle through school paperwork on my own, because my parents’ English was limited and they couldn’t always be there motivating us through the process. If I wanted to succeed academically, my perseverance, and strength would be tested.

Perseverance, strength and good education are the gateway to success. And this is especially true when you look at the obstacles that Latinos have to overcome to succeed in public schools. For instance, while the national high school dropout (輟學(xué)) rate has decreased significantly, we still have the highest dropout rate in the country. We are more likely to live in poverty and attend racially separated schools. These issues create many other problems for Latinos.

To help relieve my family burden, I found my first job when I was 14 at a local hotel. Despite the long hours on my new job, I worked hard. Meanwhile, I continually stressed the importance of getting a respectable education and did everything possible to get one step closer to making my dream a reality.

Nearly a decade later, I became the first in my family to graduate from the University of Southern California. Knowing the social, economic, and political struggles that a community faces, I began to pursue journalism to give the disadvantaged minorities a voice.

【1】What inspired the author when he was a child?

A. The encouraging words from his father.

B. A nurse in his father’s hospital.

C. His curiosity about the stethoscope.

D. The hardships he suffered.

【2】The example in the third paragraph given by the author suggests .

A. more Latinos are receiving higher education in America

B. Latino immigrants are still facing many problems

C. American education system is better constructed

D. racial separation has long been forbidden in America

【3】The author chose to become a journalist, hoping to .

A. show his success as a Latino

B. enjoy a different life

C. speak for the disadvantaged Latinos

D. repay the sacrifice his parents made

【4】What does the author try to tell us with his own experience?

A. Immigration is an approach to personal success.

B. Good education is a way to successful life.

C. Disadvantaged Latinos are facing fewer challenges.

D. American Dream is inaccessible to the Latinos.

【題目】If you’re dreaming of visiting one of those picture-perfect European towns filled with old-world attractiveness and scenic beauty, here is a look at the most beautiful small towns in Europe.

Manarola

Portmagee, Ireland

In a country filled with beautiful towns, Portmagee, is a standout, sitting on the southwest coast of Ireland.This postcard-perfect seaside fishing town has a row of brightly colored buildings along with a rich and colorful history.

【題目】任務(wù)型閱讀
A conflict at work is common. If you can avoid conflict, it means you will win what you want regardless of what the other person wants. Since the potential problem has not been removed, it will simply reappear later
Be aware of the fact that some conflicts are unavoidable at work. On many occasions(場(chǎng)合), conflict and disagreement are likely to happen. But when a conflict happens it is not the end of the world.Conflicts mean that people care enough to disagree strongly. The trick is not to allow the conflict to go on forever.
Solve a conflict when it starts, as it only gets worse with time going by. Everyone is waiting for the other to admit he or she is wrong and gets more unpleasant after the conflict has lasted a while. It is necessary to interrupt the "waiting game" before it gets to that point.
Ask nicely. If somebody has done something that makes you angry, or if you don't understand their viewpoints or actions, simply asking nicely about them can make a world of difference. Never assume that people do what they do to annoy or hurt you. Sometimes there is a good reason why that person does what he or she does, and a potential conflict disappears right there.
Appreciate.Tell them why it is worth it to you to solve the conflict. This can be difficult as few people find it easy to appreciate a person they disagree strongly with, but it is a great way to move forward.
A. Praise the other part in the conflict
B. Deal with conflicts sooner rather than later.
C. Invite the other person to talk about the situation.
D. Do remember to make an enquiry, not an accusation of any sort.
E. Here are the necessary steps to effectively get rid of conflicts at work
F. On the contrary, it can be the beginning of an interesting learning process.
G. Clear thinking is unlikely to happen while an argument continues to boil over.
