However, it’ s never an easy one to perform especially for those with children. So when Ifound out I was going to be stationed in South Korea for a year, I was nervous about how my fivechildren, particu larly my eldest daughter Abigail, would take the news since it meant I wouldnhome to see her graduate from high school.Incredibly, Abigail told me not to worry and even suggested we live stream the event amongfamily members when I leaked the news.“ We’ ve been lucky you haven’ t had to be sent abroad yet.Anyway we can get connected through the Internet. See me on your phone on my spot.”Abigai said. She stepped into many of my roles when I was gone. I wanted to find a way to thank her andshow her how proud I was of her. I started planning the special surprise when my request to returnhome a few weeks early to attend Abigail’ s graduation ceremony was approved.When my time in South Korea finally came to an end, I flew home, rented a car, and stayed in ahotel. And on Abigail’ s graduation day, I hid in an office behind the stage waiting until I heard mydaughter ’ s name called. I just kept thinking“ Don’ t cry. Don’ t trip in your heels. Donlast! Abigail was up on stage. I slipped up behind her, whispered in her ear, and around she turned!“ I was just thinking, like,‘ You aren’ t supposed to be here. What? What? How?’ It was the shock... I ’ mpretty sure my dad made people he didn ’event know cry. Emotional for everyone,”Abigail cried.You know what followed: Embraces, kisses, tears, laughs, flowers, wishes... ; aren’ t they wh family have in store?24. What worried the author most?A.

But a new study published in Science Advances paints a more complex picture.While organic produce is likely slightly healthier to eat and, in some ways, more sustainable to grow,there are also downsides.Organic fruits and vegetables typically cost more than conventional ones. To get a certificate asorganic, farmers must meet specific criteria, including growing produce without the use of geneticengineering and chemical inputs. Without these methods, the growing process typically requires morelabor, time, and money, a cost that is passed down to consumers.It ’ s true that in many ways, organic is more sustainable than conventional farming. But when itcomes to environmental concerns such as greenhouse gas output and water loss, the comparison getscomplex. Organic farms produce less gas output per acreage. However, because they are barred fromusing genetic engineering, pesticides (杀虫剂), and other methods that increase efficiency (效率),organic farms also produce an estimated 19% to 25% less yield than conventional farms. Whilethere isn ’ t a whole lot research on the topic, the few studies that do exist suggest green gasoutput and water loss might actually be higher on organic farms, on a per unit basis, says studyauthor Verena Seurfert.In addition, while organic produce is likely more nutritious than conventional fruit and vegetables, there ’nots a lot of evidence to support the claim that these often slight differencesinfluence consumer health. The same is true for pesticide remainder. In developed countries, where pesticide use is tightly regulated, there ’nos scientific consensus on how these often slight differences influence human health.Still, Seurfert stresses that if you can afford to eat organic, you should do so. Organic farms provide safer work environments for workers, plus they support great biodiversity. The real takeaway from her study is not that organic is bad but that the practice needs more study to increase yield without lowering sustainability.But if you can ’affordt to buy organic produce, don ’stress too much, particularly from a nutritional perspective.28. What does the underlined word downsides“”in Paragraph 1 most probably mean?A. Dangers.B. Drawbacks.C. Benefits.D. Differences.29.Which key factor makes it hard to compare organic farming and conventional farming whenit comes to environmental concerns?A. The yield.B. The price.C. The water loss.D.

It isn’ t wise for consumers to buy organic products.D. Pesticide remainder does no harm to people’ s health.31. In the author, s opinion, why should we support organic produce?A. It’ s environmentally friendly.B. It’ s more nutritious.C. It helps keep the variety of plants.D. It’ s safer for consumers.DEvery ocean lover knows the dangers of getting caught in a rip current (离岸流). Experienced swimmers know it is relatively easy to escape the narrow channel of the fast moving water by floating and allowing it to drag you further into the ocean or by swimming alongside the shore. However, inexperienced beachgoers often panic, and try to swim to land, placing themselves at risk of drowning due to tiredness. According to the US National Ocean Service, the currents kill about100 Americans each year and account for 80% of all lifeguard rescues. These scary statistics may soon be a thing of the past, thanks to Clever Girl, a smart buoy ( 浮标 ) that warns swimmers of the presence of deadly rip currents.The smart device is the brainchild of Australian teenager Maddison King, who created Clever Girl as a project for her Grade 12 Design and Technology class. The 18-year-old, who works as a lifeguard during her spare time, came up with the brilliant idea after discovering that most children were unable to detect rip currents.The basketball-sized plastic buoy, which can be attached to a chain of similar devices or theocean floor, is fitted with a small propeller (螺旋桨). When the water travels at speeds of over 70centimeters per second, it spins the propeller fast enough to power the light atop the buoy,warning swimmers to stay clear of the area.Though it sounds simple enough, the youngster had to overcome numerous design challenges.For instance, she picked a red light since it is easy to see in the bright sunlight and also because thecolor serves as a universal warning sign for tourists that do not speak the local language. Thedevice ’ s smooth surface and highandlesh ensure swimmers do not get hurt, while the black, white,and red striped underside, keeps sharks and other animals at bay.Future versions might include something like a warning siren, which would provide soundwarnings of rip currents. Besides, the present model cost about $ 300 to make.“ That ’ s beyond my purse. ” she laughs,“ the cost has to be cut down.”32. Which of the following is the right way to escape the rip current?A. Waiting for rescues.B. Swimming to the shore.C. Moving fast in the water.D. Floating with the water.33. Why did Maddison decide to invent Clever Girl?A. She wanted to challenge her creativity.B. She was motivated by her working experience.C. She was supposed to complete it for her class.\D. She was scared by the statistics of the government.34. What do we know about the present version of Clever Girl?A. It ’ s not available on the market.B. It ’ s quite attractive for sea animals.C. It ’ s based on a complex theory.D. It can give warnings in different ways.35. What could the future version of Clever Girl be like?A. Safer and greener.B. Cheaper and safer.C. Greener and more effective.D. Cheaper and more effective.第二节（共 5 小题 ;每小题 2 分，满分10 分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
