Bob Baffert, American Pharoah’s trainer said, “He did great yesterday.It was a beautiful moment.” The Triple Crown races last for five weeks on circular tracks of different lengths.The races are short, but the horses use a great amount of energy dashing to the finish line.The Belmont Stakes is the last one of the races, and the longest.American Pharoah led the entire race and won the race. Taking home the Triple Crown is no easy matter.The horses require many hours of training to prepare for the intense demands of racing.The raw talent and genetics of the horses also play an important role in developing winners.“Nobody__can__make__a__slow__horse__a__fast__horse,” American Pharoah owner Ahmaed Zayat said. Victor Espinoza is the jockey who rode American Pharoah.He lost his last two Triple Crown tries with different horses, but was able to bring home the prize after Saturday’s race.“I looked at that prize and I was very excited and kind of angry because two times before I couldn’t get it,” Espinoza said. Before leaving Belmont Park, American Pharoah joined photographers and fans on the grass.He posed for pictures and let people from the crowd pet him. It will be up to American Pharoah’s trainer to map out his next racing steps.“He’s an athlete.We have to keep him moving,” said Baffert.“He’s so happy when he’s on that track.” 【语篇解读】 本文是记叙文。一匹马在赛马比赛中获胜,夺得三重冠。 1.What can we infer about the Triple Crown races from Paragraph 1? A.They are really tough. B.They are world-famous. C.They are well organized. D.They are very interesting. 答案 A [推理判断题。由第一段开头的American Pharoah proved it’s not impossible to win the Triple Crown及段末的The 3-year-old horse is the first horse...the history of horse racing可推断,这是一项很艰苦的比赛。] 2.What does the underlined part in Paragraph 4 stress? A.The importance of a horse’s trainer. B.The importance of a horse’s jockey. C.The importance of a horse’s mental ability. D.The importance of a horse’s natural ability. 答案 D [句意理解题。由上文的The raw talent and genetics of the horses also play an important role in developing winners可推断,要想在赛马比赛中获胜,马的天赋很重要。] 3.Victor Espinoza was kind of angry because________. A.he was disappointed in his horse B.he thought the races were not fair C.he didn’t win the Triple Crown races D.he failed twice before winning the prize 答案 D [细节理解题。由第五段中的because two times before I couldn’t get it可知。] 4.In the future, American Pharoah will________. A.go on racing B.be a pet horse C.be kept in a park D.live a happy life alone 答案 A [细节理解题。由最后一段中的map out his next racing steps及He’s an athlete.We have to keep him moving可知,这匹马将来会继续参加比赛。] B Palm oil (棕榈油) is the most widely consumed vegetable oil in the world. The oil is popular because it has a high melting point and contains healthy fats.The former makes it easy to spread, while the latter makes it beneficial to our body. But__the__oil’s__popularity__comes__at__a__high__price.Palm trees need lots of land to grow.As a result, thousands of rainforests in Indonesia, the world’s biggest palm oil producer, are being destroyed to make room for them. With half of palm oil coming from Indonesia, one of the victims is the orangutans (猩猩).In the last 20 years, over 80% of their habitat has been destroyed.What was worse, in 2015, wildfires endangered one-third of the remaining orangutans.Some palm plantations (种植园) have also threatened tigers and elephants and caused water and air pollution. Though the easiest way of dealing with the problem is to stop using palm oil so widely, it’s not easy given that no other natural vegetable oil has both the qualities.Now scientists are creating an alternative using food waste and M.pulcherrima, a yeast (发酵物) that grows on leaves, fruits and flowers.It takes in the sugars from the waste and turns it into thick oil that has similar qualities to palm oil.Besides, the best part is that the alternative can be widely produced regardless of any kind of weather. Scientists say their biggest challenge is to find a cheap way to change the sugars in the food waste to a form the yeast can consume easily.After some experiments, they are able to copy the process by using a microwave.The team is now trying to test if they can produce the oil in larger quantities and at a lower cost. Though optimistic, experts are still struggling.After all, it’s not the first time that an alternative has been tried.However, scientists didn’t get good results from past efforts.Meanwhile, things are not looking promising for orangutans.Scientists think that if the rainforest destruction is not banned, orangutans will die out. 【语篇解读】 本文是说明文,题材为环保科普类。人们为了棕榈油而大肆砍伐雨林,结果威胁到了猩猩的处境。人们不得不想出办法来制造棕榈油的替代品,然而这种办法前景也不容乐观。 5.What does the underlined sentence mean? A.It is not easy to get palm oil. B.Palm oil brings great benefits to people. C.People need to pay a lot of money for palm oil. D.The popularity of palm oil causes some problems. 答案 D [句意理解题。根据画线句子下文语境可知,棕榈油的广泛使用引起了一些问题。在印度尼西亚,人们为了种植棕榈树,大肆砍伐雨林,从而破坏了猩猩的栖息地;棕榈种植园还引起了水污染和空气污染。] 6.What do we know about the new alternative? A.It tastes like sugar. B.It is made from leaves and fruits. C.It can be produced in any weather. D.It has better qualities than palm oil. 答案 C [细节理解题。根据文章第四段Besides,the best part is that the alternative can be widely produced regardless of any kind of weather可知,这种棕榈油的替代品可以在任何天气下培育。] 7.The biggest problem scientists are faced with is how to________. A.change the sugars in the food waste B.reduce the cost of producing the oil C.produce the oil without a microwave D.easily change the form of the yeast 答案 B [细节理解题。根据文章第五段Scientists say their biggest challenge is to find a cheap way to change the sugars和本段最后The team is now trying to test if they can produce the oil in larger quantities and at a lower cost可知,科学家面临的最大问题就是如何降低生产这种油的成本。] 8.What attitude do scientists hold towards orangutans’ future? A.Optimistic. B.Doubtful. C.Indifferent. D.Worried. 答案 D [观点态度题。根据文章最后一段Meanwhile,things are not looking promising for orangutans.Scientists think that if the rainforest destruction is not banned,orangutans will die out可知,科学家认为如果不禁止滥伐雨林,猩猩可能就灭绝了。] Ⅱ.阅读七选五 Summer survival guide Finally...the season of sun, fun, and freedom!__1__Follow these steps to keep yourself healthy and safe. Don’t rely on sunscreen.Yes, you need to slather (大量地涂抹) sunscreen on exposed skin, but other precautions are just as important.Seek shade between 10 am.and 4 pm., and protect your skin and face with clothing, a hat, and shades. __2__If you feel thirsty, you’re already dehydrated (脱水的)—that puts you at an increased risk of hot weather-related illnesses like heat exhaustion and heat stroke (中暑).

Learn these lifesaving swim moves. Drowning is the second-most-common cause of accidental injury or death in adolescents.__5__Stick to zones with a lifeguard present, never swim alone, and learn these simple swimming skills—even if you never plan on getting wet.1.Turn yourself around in a full circle while in the water.2.Float on your back.3.Tread (踩) water.4.Swim 25 yards (the length of a standard swimming pool). A.Try to reduce the risk of brain injury. B.Float on your back if your arms get tired. C.Don’t wait until you’re thirsty to drink up. D.Luckily, there are easy ways to cut this risk. E.Try and aim to be back at your usual activity level by day 14. F.Don’t waste a minute of it feeling anything less than awesome.
