— I got ______ okay grade, but Mr．Jones gave Sarah top marks．She’s ______ teacher’s pet, you know.
A． 不填; a B． an; 不填

C． 不填; the D． an; a

【答案】D

【解析】第一個(gè)空格中后的okay grade是泛指，故用不定冠詞an;而第二個(gè)空后的teacher’s pet也同樣是在這個(gè)語(yǔ)境中第一次出現(xiàn)，也是泛指同樣是用不定冠詞a。故選D。句意：--你的作文怎么樣？ -- 我得了一個(gè)不錯(cuò)的分?jǐn)?shù)，但瓊斯先生給了薩拉最高分。她是老師的愛(ài)徒。

FIVE WAYS TO KILL YOUR DREAMS

I dedicated the past two years to understanding how people achieve their dreams. When we think about the dreams we have, and the footprint we want to leave in the universe, it is striking to see how big of an overlap there is between the dreams that we have and projects that never happen. So I'm here to talk to you today about five ways how not to follow your dreams.

【1】______

You know the story, right? The tech guy built a mobile app and sold it very fast for a lot of money. You know, the story may seem real, but I bet it's incomplete. If you go investigate further, the guy has done 30 apps before and he has done a master's on the topic, a Ph.D. He has been working on the topic for 20 years. This is really interesting. I myself have a story in Brazil that people think is an overnight success. I come from a humble family, and two weeks before the deadline to apply to MIT, I started the application process. And, voila! I got in. People may think it's an overnight success, but that only worked because for the 17 years prior to that, I took life and education seriously. Your overnight success story is always a result of everything you've done in your life through that moment.

【2】______

Constantly, people want to help out, right? All sorts of people: your family, your friends, your business partners, they all have opinions on which path you should take: "And let me tell you, go through this pipe." But whenever you go inside, there are other ways you have to pick as well. And you need to make those decisions yourself. No one else has the perfect answers for your life. And you need to keep picking those decisions, right? The pipes are infinite and you're going to bump your head, and it's a part of the process.

【3】_____

So when your life is going great, you have put together a great team, and you have growing revenue, and everything is set — time to settle. When I launched my first book, I worked really, really hard to distribute it everywhere in Brazil. With that, over three million people downloaded it, over 50,000 people bought physical copies. When I wrote a sequel, some impact was guaranteed. Even if I did little, sales would be okay. But okay is never okay. When you're growing towards a peak, you need to work harder than ever and find yourself another peak. Maybe if I did little, a couple hundred thousand people would read it, and that's great already. But if I work harder than ever, I can bring this number up to millions. That's why I decided, with my new book, to go to every single state of Brazil. And I can already see a higher peak. There's no time to settle down.

【4】______

I constantly see people saying, "Yes, I had this great idea, but no investor had the vision to invest." "Oh, I created this great product, but the market is so bad, the sales didn't go well." Or, "I can't find good talent; my team is so below expectations." If you have dreams, it's your responsibility to make them happen. Yes, it may be hard to find talent. Yes, the market may be bad. But if no one invested in your idea, if no one bought your product, for sure, there is something there that is your fault. Definitely. You need to get your dreams and make them happen. And no one achieved their goals alone. But if you didn't make them happen, it's your fault and no one else's. Be responsible for your dreams.

【5】_____

Once I saw an ad, and it was a lot of friends, they were going up a mountain, it was a very high mountain, and it was a lot of work. You could see that they were sweating and this was tough. And they were going up, and they finally made it to the peak. Of course, they decided to celebrate, right? I'm going to celebrate, so, "Yes! We made it, we're at the top!" Two seconds later, one looks at the other and says, "Okay, let's go down." Life is never about the goals themselves. Life is about the journey. Yes, you should enjoy the goals themselves, but people think that you have dreams, and whenever you get to reaching one of those dreams, it's a magical place where happiness will be all around. But achieving a dream is a momentary sensation, and your life is not. The only way to really achieve all of your dreams is to fully enjoy every step of your journey. That's the best way.

【題目】閱讀理解。

There are many older people in the world and there will be many more. A littleknown fact is that over 60 percent of the older people live in developing countries. According to the World Health Organization，by 2020 there will be 1 billion，with over 700 million living in developing countries.

It is a surprising fact that the population ageing is particularly rapid in developing countries. For example，it took France 115 years for the proportion of older people to double from 7 percent to 14 percent. It is estimated(估計(jì)) to take China a mere 27 years to achieve this same increase.

What are the implications(暗指) of these increased numbers of older folk？One of the biggest worries for governments is that the longer people live，the more likelihood there is for diseases and for disability. Attention is being paid to the need to keep people as healthy as possible，including during old age，to lessen the financial burden on the state.

Another significant problem is the need for the younger generations to understand and value the older people in their society. In some African countries，certainly in Asia，older people are respected and regarded as the ones with special knowledge. Yet traditions are fading away daily，which does not ensure the continued high regard of older people. As society changes, attitudes will change.

Much needs to be done to get rid of age discrimination (歧視) in employment. Lifelong learning programs need to be provided to enable older people to be active members in a country’s development.

Social security policies need t be established to provide adequate income protection for older people. Both public and private schemes are vital in order to build a suitable safety net.

To achieve equality in such matters will take considerable time and effort. One thing is sure：there is no time to be lost.

【1】The proportion(比例)of older people________.

A. is bigger in developed countries than in developing countries

B. is one seventh of the population in developing countries

C. will increase much faster in China than in France

D. will be sixty percent in developing countries by 2020

【2】According to the passage，which of the following are governments most worried about?

A. The diseases and disability of older people.

B. The longer life and good health of people.

C. The loss of taxes on older people.

D. The increasing respect for older people.

【3】Which of the following measures is NOT mentioned to solve the population ageing problem?

A. Getting rid of age discrimination in employment.

B. Ensuring adequate income protection for older people.

C. Providing free health care for sick older people.

D. Supplying lifelong learning programs to older people.

【4】The author concludes in the last paragraph that________.

A. governments have spent lots of time in solving the ageing problem

B. population ageing is a hard problem，but it needs to be solved urgently

C. people are too busy to solve the population ageing problem

D. much time and effort will be lost in solving the ageing problem

How smartphones could be ruining your relationship

We carry our smartphones with us wherever we go. We didn’t have the time to set any boundaries for smartphone usage, and now we find ourselves unable to save our relationships. Smartphones are very useful in many circumstances. 【1】

Lack of mindfulness

We become totally lost in our digital lives. Smartphones get in the way of our relationships, making it impossible for us to wholeheartedly devote our attention to the present moment. 【2】

Loss of communication

In fact, some people talk more about their relationships on Facebook than they do face-to-face with the person they’re actually in a relationship with! 【3】 Why not do something together, other than sitting side by side staring at the displays on your individual phones? Excessive (過(guò)度的) smartphone use makes it impossible for us to build any new, sincere relationships.

Prioritizing (優(yōu)先) the wrong models of communication

【4】 We damage our happiness and harm our relationships, failing to see which is more important in our life. Small, precious moments are slipping away because we’re focused on reading all of our emails, and we get unreasonably anxious if we put our phones away even for 30 minutes.

【5】

Unless you put boundaries to your phone usage, you will become addicted to it. We shouldn’t feel stressed and anxious when we’re in phone-free areas. We should be happy that we can value special moments happening each day and make good use of our time and our relationships.

A. Breakdown of elationships

B. Stress and smartphone separation anxiety

C. However, they can harm our relationships in indirect ways.

D. As a result, we lose many moments that are special and never to be lived again.

E. You don’t even have to take a smartphone addiction test to see if you’re addicted to it.

F. Why choose to communicate through social media, rather than enjoy a friend’s company?

G. We’ve become addicted to digital communication, regarding real-life communication as secondary.
