【題目】 (共5小題；每小題2分，滿分10分)

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

As warming continues, scientists warn the oxygen content of oceans across the planet could be more and more reduced, with serious consequences for the future of fish and other sea life.

1 One is the simple fact that as water gets warmer, it can hold less dissolved (溶解的) oxygen. The other reason is less obvious. The entire ocean gets its oxygen from the surface — either from the atmosphere, or from photosynthesizing algae floating at the top of the sea. 2

Global warming is expected to reduce the mixing of the ocean by making surface seawater lighter. That’s because in a warmer world we can expect more rainfall and more melting(融化) of glaciers, icebergs, and ice sheets. 3 The extra heat from the warming atmosphere will also make surface water expand and thus make it lighter still. 4 Instead, more of the oxygen will remain near the surface, where it will be used up by oxygen-breathing organisms.

A low-oxygen ocean may become an inescapable feature of our planet. A team of Danish researchers wondered how long oxygen levels would drop if we could somehow reduce our carbon dioxide emissions to zero by 2100. They determined that over the next few thousand years oxygen levels would continue to fall, until they declined by 30 percent. The oxygen would slowly return to the oceans, but even 100,000 years from now they will not have fully recovered. 5

A. It’s not known why the oxygen level of oceans has reduced.

B. Scientists point to two reasons to expect a drop in ocean oxygen.

C. Fresh water’s inpouring will make the water at the ocean’s surface lighter.

D. The oxygen then spreads to the deep ocean as the surface water slowly sinks.

E. Global warming has caused the reduction of the oxygen content of oceans worldwide.

F. The light surface water will be less likely to sink so the deep ocean will get less oxygen.

G. If they are right, we have every reason to worry about the major effect it has on sea life.

【3】C

【4】F

【5】G

【解析】

【文章大意】本文是說(shuō)明文。文章簡(jiǎn)要介紹了海水中氧氣含量降低的主要原因及其可能對(duì)海洋生物帶來(lái)的長(zhǎng)期的影響。

【1】從文章篇章結(jié)構(gòu)分析，本空為段落主旨句。本段介紹了全球變暖使海洋含氧量降低的原因，并且"One" "The other reason"與B項(xiàng)中的"two reasons"相呼應(yīng)，故選B。

【2】根據(jù)段落主旨和空前的"The entire ocean gets its oxygen from the surface...at the top of the sea"可知，此處是通過(guò)說(shuō)明海洋中氧氣的來(lái)源與循環(huán)來(lái)解釋海洋含氧量下降的原因的，故D項(xiàng)"然后，隨著表層海水的慢慢下沉，氧氣擴(kuò)散至海洋深處"符合語(yǔ)境。

【3】根據(jù)空前的內(nèi)容和常識(shí)可知，雨水和冰川、冰山及冰原融水都屬于淡水，海洋中的水是咸水，而淡水的密度比咸水的小，因此淡水的注入會(huì)使海洋表面的水變得更輕。故C項(xiàng)符合語(yǔ)境。C項(xiàng)中的"make the water... lighter"與下文中的"make it lighter"的對(duì)應(yīng)關(guān)系亦是提示。

【4】根據(jù)空前的"The extra heat from the warming atmosphere will..."和空后的"Instead, more of the oxygen will remain..."可知，F(xiàn)項(xiàng)與空前的句子的句式相同，且與空后的句子的內(nèi)容存在語(yǔ)意上的轉(zhuǎn)折關(guān)系，故F項(xiàng)符合語(yǔ)境。

【5】G項(xiàng)中的"they"與上文中的"A team of Danish researchers"相呼應(yīng)，且上文講到即使我們把二氧化碳的排放降低到零，海洋含氧量也需要很長(zhǎng)時(shí)間才能恢復(fù)，其對(duì)海洋生物造成的影響將是長(zhǎng)期的，故G項(xiàng)"如果他們是對(duì)的，那么我們完全有理由對(duì)它對(duì)海洋生物的重大影響感到擔(dān)憂"符合語(yǔ)境。

【2】Accept this and move on.Give yourself some time to have sweaty palms or a shaky voice,since it will get better with practice.

Ask people open-ended questions.To begin practicing opening up,you need to engage in honest,open conversation.Try a question like,"How are things going at work?"instead of "How's it going?"to get an open answer. Then,in turn answer open-ended questions with honest answers,instead of "Fine" or "OK".【3】However,in most cases people are flattered that you are listening to them and interested in their life.

Try emulating（效仿）someone who is very open.Observe them in a social situation.Then,try to act as if you are them occasionally.Many open behaviors are learned,and not a natural part of personality.【4】

Avoid being a "know it all".Some people think advice is opening up,but it is unlikely to help you more open. When you want to give advice,listen and try to learn something new from the situation.

【5】Schedule at least one long conversation per week.In the conversation you tell someone about the emotional and difficult part of your life.Get into the practice of opening up about what's good and bad in your life.

【題目】Knowing your neighbors can make you feel safer and can make your life a little more enjoyable. 【1】

Start a Facebook group. Many online groups already exist for local communities, but they may just focus on swapping and selling objects, or simply for exploring the local area. 【2】 For example, starting a Facebook group.

Get volunteering. Volunteering is a great way to meet like-minded neighbors and make a difference to your community. 【3】 Charities are the most obvious place to start. Charities, large or small, are always looking for help in regions across the UK. A simple Google search can help you discover local charities and volunteer opportunities.

Practice everyday kindness. Kindness is the start to possible long-lasting friendships. Everyday acts of kindness can be as simple as saying hello when you see your neighbors in the street or the supermarket. It may be seeing someone struggle with the gardening and offering your help. 【4】

Start an exercise group. There are a rare few of us that are motivated to start exercising, and even fewer that enjoy going it alone. 【5】 Plan big walks of your area and ask neighbors to come along. You could sign up together to attempt a marathon or half marathon. Or perhaps you can arrange a Zumba, yoga, or aerobics (有氧運(yùn)動(dòng)) class in the community centre.

A. However, you are often too busy to realize this.

B. There are many ways to volunteer in your local community.

【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.
