【解析】

本文是說明文，告訴我們保護(hù)視力的重要性以及保護(hù)視力的方法。

【1】考查代詞。句意：所以我們的工作是照顧他們一輩子。they是人稱代詞的主格形式，短語take care of后接賓語，應(yīng)用人稱代詞的賓格形式，故填them。

【2】考查名詞單復(fù)數(shù)。句意：好消息是，如果我們每天做幾件簡單的事情，就可以保護(hù)我們的視力。a few意為“少數(shù)幾個(gè)”，后接可數(shù)名詞的復(fù)數(shù)形式，故填things。

【3】考查非謂語動(dòng)詞。句意：好消息是，如果我們每天做幾件簡單的事情，我們可以保護(hù)我們的視力（視力），減少傷害眼睛的風(fēng)險(xiǎn)。短語 the risk of doing …意為“…的風(fēng)險(xiǎn)”，在介詞of后接動(dòng)名詞作賓語。故填hurting。

【4】考查非謂語動(dòng)詞。句意：幾乎所有的醫(yī)生都告訴我們多吃新鮮的水果和蔬菜。短語tell sb. to do…“告訴某人做….”, 用不定式作賓語補(bǔ)足語。故填to eat。

【5】考查介詞。句意：當(dāng)我們長時(shí)間在明亮的陽光下時(shí)，我們需要保護(hù)自己的眼睛。短語in the sunlight “在陽光下”。故填in 。

【6】考查定語從句。句意：最好的方法是戴上100%紫外線防護(hù)的太陽鏡。分析句子結(jié)構(gòu)，空后是定語從句，修飾先行詞sunglasses，指物，在從句中作主語，用which/that引導(dǎo)定語從句。故填which/that。

【7】考查形容詞。句意：當(dāng)我們處理危險(xiǎn)化學(xué)品時(shí)，保護(hù)我們的眼睛是很重要的。修飾名詞chemicals，應(yīng)該用形容詞；danger 是名詞，形容詞是dangerous。故填dangerous。

【8】考查副詞。句意：最后，我們不應(yīng)該在電腦或電視屏幕前花太多的時(shí)間。此處用副詞finally表示次序，意為“最后”，是獨(dú)立成分。故填Finally。

【9】考查固定短語。句意：醫(yī)生建議我們每十五到三十分鐘休息一次。短語take a short break “短暫休息一會(huì)”。故填a 。

【10】考查主謂一致。句意：有良好的視力是很重要的。動(dòng)名詞短語Having good eyesight作主語謂語動(dòng)詞應(yīng)該用單數(shù)；根據(jù)語境，句子說的客觀事實(shí)，用一般現(xiàn)在時(shí)。故填is。

當(dāng)不定式動(dòng)名詞或者從句做主語時(shí)，謂語動(dòng)詞應(yīng)該用單數(shù)

To obey the law is everyone's duty. 遵守法律是每個(gè)人的職責(zé)。(不定式作主語)

Eating too many sweets has ruined your teeth. 吃太多的糖毀掉了你的牙齒。(動(dòng)名詞短語作主語)

Why he did it was very clear. 他為什么那樣做還不清楚。(從句作主語)

如本題第10處錯(cuò)誤，動(dòng)名詞短語Having good eyesight作主語，謂語動(dòng)詞應(yīng)該用單數(shù)，be動(dòng)詞用is。

【題目】 The cracked step four years ago was the start of it. That day, I awoke tired—the children were tiny and needing so much—and I had a golden afternoon of rest ahead, my mother stepping in to allow me to catch up on my sleep. I dropped them off and drove home—the sun shining and my bed signaling. As I was about to enter the house, I caught sight of a deep crack beneath my feet.

Without thinking, I turned around, walked back to the car and drove to a DIY store. Four hours later, I had all the tools, mixed my own cement, filled in the crack and repaired the foundation. Perfect. As I stood up to take a photo of my handiwork, I realized that I was trembling. I’d forgotten my shot at a nice long nap, and my children were already on their way home. That sleep... that promise to self was broken, because I had focused, instead, on the crack in the step.

Suddenly, everything started to hurt. My head, my throat, my back. I couldn’t stop shaking. What earned then is that when we break the promises we make to our bodies they will not be silenced. This is when we overwork and overthink to the point of breaking down. Ironically (諷刺地), for many of us, it is only when we have no choice— when we fall ill—that we learn to listen. For me, when that crack ended in a hospital stay which sent me to bed for two unmoving weeks when my body worked to clear two different infections, the lesson is ever present. I did it to myself—a whole twisted spin on DIY.

Sadly it took another two ridiculous DIY projects to finally get through. The cracks will never be fully filled. Focus, then, on your own inner core, the feeding of light, fire and strength.

【1】What made the author so sleepy in the first place?

A.Taking care of the kids.B.Asking her mother for help.

C.Driving to her mother’s houseD.Dealing with DIY projects.

【2】How did the author feel as soon as she finished her repair work?

A.RegretfulB.Upset

C.ProudD.Thankful

【3】What can be implied from Paragraph 3?

A.Our health is ignored deliberately.

B.Our body will respond to what we do.

C.The author took her mother’s advice.

D.The author was infected before the DIY.

【4】What is the author’s purpose in writing the text?

A.To describe an unfortunate event.

B.To show the danger of DIY.

C.To stress the importance of sleep.

D.To encourage focusing on oneself.

【題目】 When my husband and I moved back to the United States years ago, we had been living an adventurous life on a boat overseas. We moved to Maine and fell in love with a piece of land. It came with a huge farmhouse much larger than we needed. We went rapidly from living in an extremely small space on the water with only two bags to a life on land as a family of four in a big house jammed with stuff.

How did we end up with so much stuff? We just didn't see things piling up so quickly. It's an embarrassment of riches. It's an overabundance. And it's burying us.

A couple of weeks ago, going through a pile of books I’d organized, I found my late mother's now-twenty-year-old copy of “Simplify Your Life" by Elaine St. James. I’d read it a number of times, adding my own penciled notes and folding down more pages.

Wondering if St. James wrote other books on the topic, I began an Internet search that led me deeper and deeper into simplicity, and a concept that was new to me, zero waste. I sensed that what was missing from our life, from our home, was emptiness. My house can't breathe, it's no wonder I feel like I can't either.

Now, my husband and I have undertaken an experiment that we hope will lead to a major lifestyle shift for our whole family. I first started to declutter and downsize by cleaning my kitchen. I emptied out my cupboards and drawers. I put everything needed on our dining-room table. Everything else went into a huge bin for sale. My drawers are beautiful now and I’m content to take this step.

Like any new beginning, there are hesitations. But in a few months, we will move into a new house less than half the size of the one we have. Can my two kids adjust to the idea of reducing their two separate rooms to one small shared bedroom with just a few toys? I can see I'm still thinking about what I will lose. But what I hope becomes clearer is what we will gain by letting go.

【1】How did the author feel about the life back to the United States?

A.She enjoyed the new spacious house.

B.She loved the abundance of materials.

C.She complained about owning too much.

D.She desired a much richer life.

【2】Why did the author mention Elaine St. James and her book?

A.To show what a great influence James had on her.

B.To advise more people to read James's book.

C.To indicate how her late mother liked reading.

D.To explain why a simple life counts to everyone.

【3】What does the underlined word “declutter" mean in Para 5?

A.recoverB.remove

C.prepareD.escape

【4】What is the author doing according to the last paragraph?

A.Persuading her kids to live simply.

B.Reflecting her hesitations about letting go.

C.Questioning her sudden change on life.

D.Missing her life on the boat.

Last year, a report by a committee of education experts said that a lot of American students cannot write well. The report noted the concerns of business leaders and teachers. The experts said that more students should have to pass a writing test 【1】 they can finish high school. They pointed out major college entrance tests are changing now 【2】 (include) a writing part.

Educators know that teaching students to write well is not easy. One problem is the amount of time needed to read through large amounts of work. So some companies 【3】 (develop) computer programs that can grade students writing more quickly than a person can. Writing tests can also cost 【4】 (little) to carry out by computer than paper-and-pencil. These computer systems, known as e-readers, use artificial intelligence to think in a way 【5】 teachers. For two years, both a computer and humans graded the student writing. Officials say there was almost no difference between the computer grades and 【6】 given by the human readers.

The entrance test commonly 【7】(use) by business schools, the GMAT, already uses e-readers. The GRE and TOEFL tests might start; officials are deciding.

Systems 【8】(use) to grade writing in college classes as well. The computers read a few hundred examples of student writing already graded by humans. Then the systems compare new writing against those already examined.

Some teachers say machines can never do the job as well as people can. A computer can find spelling and grammar mistakes, but it can never really understand 【9】 a writer is trying to say. Critics say a program cannot follow a thought or judge humor or understand a beautifully expressed idea.

But inventors of the programs say computer grading guarantees that each piece of writing is graded in the same way. They also say the systems 【10】(mean) to judge knowledge more than creativity.

【題目】 Dr. Faisal Zawawi, an Otolaryngologist and member of the McGill Auditory Sciences Laboratory, notes that when a person is exposed to loud noises it can cause short-term hearing loss but that under normal circumstances the body typically is able to repair the loss of hearing within 72 hours. However, Zawawi warns that if symptoms are not reversed (倒轉(zhuǎn)) in the first 72 hours the damage could become permanent. Due to findings in previous studies about it, Zawawi says that the team of researchers has suspected that something may stop this repair process; therefore, the team set out to determine if caffeine could be a contributing cause to hearing loss. According to the Medical Daily, the researchers tested what they suspected on female guinea pigs(FGP) (豚鼠).

To perform the test, 24 female guinea pigs were split into three equal groups with each group exposed in different levels to caffeine, and loud noises. The researchers found that the guinea pigs subjected to only sound had their full hearing recovered by day eight. However, the guinea pigs that were subjected to both caffeine and loud noise never fully regained their hearing. Therefore，the researchers concluded that caffeine is a likely contributing cause to permanent hearing loss.

“This research confirms that while a cup of coffee may seem appealing after a long night at a loud concert, drinking caffeine produces more of a risk than benefit when it comes to a person's hearing. Although further research is required to understand the effect on humans, the results are promising," says Zawawi. If the research proves successful, the removal of caffeine from your diet following noise exposure could prevent permanent hearing loss as the body will be more able to repair itself naturally.

【1】What caused the team to do the research?

A.Caffeine loving people suffering hearing loss.

B.The results about hearing loss found before.

C.The finding that FGPs are sensitive to noise.

D.The fact that many people drink coffee.

【2】What is Zawawi's view about temporary hearing loss?

A.Drinking coffee daily results in it.

B.Drink less coffee while suffering it.

C.Generally people can recover from it in 3 days.

D.The continuous noise exposure surely causes it.

【3】What can we learn about hearing from the text?

A.Coffee can stop it from recovering.

B.Coffee Can lead to quick hearing loss.

C.Hearing loss after noise exposure is normal.

D.Loud noise causes people to lose it forever.

【4】How does Zawawi assess the research?

A.It's controversial.B.It's unnecessary to carry it on.

C.It's not predictable.D.It's almost successful.
