这是一篇说明文。本文介绍了位于澳大利亚东海岸的弗雷泽岛的美丽景观。它因其独特的自然环境而成为世界遗产；岛上有超过120公里的干净海滩，还有雨林、珍稀鸟类和动物；这里还有美丽的驾车路线。
【1】下一句提到“这里的沙比撒哈拉沙漠还多。”联系下文，A选项“它是世界上最大的沙岛。”切题。该选项中的it和下一句中的it都是指的Fraser Island。故选A项。
【2】上一句提到“在沙丘之间的山谷里有淡水湖。”承接上文，F选项“岛上有100多个这样干净的小湖泊。”符合语境。故选F项。
【3】下一句提到“你需要这种车，因为你必须在沙地上开车。”联系下文，G选项“要想看到岛上所有的美景，你可以租一辆四轮驱动的汽车。”符合上下文语境。下一句中的“this type of vehicle”指代的就是G选项中的“a four-wheel-drive vehicle”。故选G项。
【4】上一句提到“弗雷泽岛上没有公路。”，承接上文，B选项“你不得不沿着海边开车。”符合逻辑，两句是因果关系。故选B项。
【5】上一句提到“如果你打算过夜，你必须在帐篷里露营，因为岛上几乎没有地方可以住”，承接上文，E选项“只有360人住在那里，并且只有几家旅馆”用来进一步说明岛上几乎没有地方可以住的原因。故选E项。
七选五的解题技巧之一是根据上下文词汇来锁定线索。即：要关注空白前后的名词和动词，然后在选项中查找它们的近义词、反义词、同义词、同类词等。其次是一些专有名词，比如说数词、代词、时间、年代、地点/名称等。如第1小题，所填A选项中的“it”和下一句中的it都是指的Fraser Island。

【题目】阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
I looked forward to a visit with my mom, who lived 2,000 miles from my home in California. Since Mom was 80 and suffered from Alzheimer’s (阿兹海默症), I realized how important it was to see her again soon.
Mom received loving care from the Sister Servants of Christ the King at a 40-bed, basic-care facility (场所) in Edgeley, North Dakota. She lived in a simple room, spent most of her day doing simple things, and seemed to be “all right, “considering that dementia (痴呆) had set in.
When Mom came in, I smiled, hugged and kissed her, and said, “Nice to see you, Mom.” She didn’t recognize who I was! I was shocked.
Stressed out, I spent several hours trying to connect with my mother—talking with her, walking around the grounds, looking at family pictures in her room, chatting with the nuns (修女) —doing whatever I could think of to help Mom recognize her son. I hoped for a recognition “wonder”. But nothing I said or did worked, I was very annoyed.
The next morning, I suddenly had an idea. I thought of something that might stir her memory (记忆).I thought of strawberry milkshake (草莓奶昔). Yes, strawberry milkshake in Edgeley, North Dakota. So I took Mom to the Edgeley Coffee Shop. I wanted to treat her here. While Mom was looking at the menu, I took Sandy, the waitress, aside, quietly told her of Mom’s dementia condition and my plan to recall her long-term memory, and ordered two strawberry milkshakes.
The first paragraph: When Sandy delivered the milkshakes, I was too nervous to say a word.
The second paragraph: There’s a simple explanation for Mom’s memory.
注意：1. 所续写短文的词数应为150左右；
2. 续写部分分为两段,每段的开头语已为你写好。

【题目】 A few weeks ago, scientists at Ukraine's Vernadsky Research Base in Antarctica found their usually white surrounds were covered in a shocking blood-red. For such a mess, the culprits behind this horrible scene are tiny.
“Our scientists have identified them under a microscope as Chlamydomonasnivalis(雪地衣藻),” said the National Antarctic Scientific Centre of Ukraine in a Facebook post.
These green algae, a type of seaweed, are common in all icy and snowy regions of Earth, from the Arctic to high mountain regions. They lie still during the freezing winter, but once the sunlight warms enough to soften their world, the algae awake, making use of the melt water and sunlight to rapidly bloom.
“The algae need liquid water in order to bloom,” University of Leeds microbiologist Steffi Lutz told Gizmodo in 2016. “The algal blooms contribute to climate change,” the center stated.
A study in 2016 showed that snow algal blooms can decrease the amount of light reflected from the snow by up to 13 percent across one melt season in the Arctic. “This will surely result in higher melt rates,” the researchers wrote.
In 2017 environmental scientists calculated that microbial communities contributed to over a sixth of the snowmelt where they were present in Alaskan ice fields. Their experiments showed that areas with more melt water led to the growth of 50 percent more algae and places with more algae melted further.
This Antarctic summer has certainly seen a lot more melt water than usual. Temperature records keep changing, leading to rapid melting previously only seen in the Northern Hemisphere.
【1】What does the underlined word “culprits” in Paragraph 1 mean?
A.Risks.B.Chances.
C.Effects.D.Criminals.
【2】What can we know about Chlamydomonasnivalis?
A.They can be found anywhere.B.They are sensitive to temperature.
C.They grow slower than before.D.They survive only one melt season.
【3】What can be inferred from the last two paragraphs?
A.Ice and snow will soon disappear in the Antarctic.
B.Microbial communities bring about extreme weathers.
C.The Southern Hemisphere is warmer than the other parts.
D.Climate change and algae growth interact with each other.
【4】Which can be a suitable title for the text?
A.Why Snow Turned Blood-red.B.How Algae Began in the Arctic.
C.Why Climate Changes Greatly.D.How the Snow Reflects Sunlight.

【题目】 It doesn't take decades of life experience to have a great idea, as many of these young inventors have proved.
The Electronic Television
The electronic television was first designed by a 14-year-old kid in 1920. Philo Taylor Farnsworth shared his concept of an image transmitting (影像传送) device, an early design of the electronic television, with his science teacher, drawing diagrams on several blackboards in class.
By the age of 21 Farnsworth had a working model which served as a basis to all later development and versions of electronic televisions, After discovering a collection of technology magazines in the attic (阁楼) of his family's new home, he developed a passion and interest in electronics, which led him to explore inventions in the field of, specifically, the image transmission.
In 1927, a few years out of high school, Farnsworth was the first inventor to transmit a television image of a dollar sign, composed of 60 horizontal lines.
Braille Language
Louis Braille suffered a serious eye injury when he was just 3 years old. Not only did the accident cause him blindness on that side, but the infection spread and blinded the other eye as well. After more than a decade of struggling with the slow system of tracing his finger over raised letters, Braille was 12 when he learned of a method of silent communication originally created for the French military. He simplified it, and in 1824 the Braille language was born.
Popsicles (冰棍)
A lot of kids are easily distracted (分散注意力)—and thanks to the short attention span of 11-year-old Frank Epperson we now have popsicles. In 1905, Epperson, a San Francisco native, was stirring powdered drink mix into a cup of water when something else caught his attention. The mixture was forgotten outside the door, and when Epperson rediscovered the drink in the morning, it was a deliciously portable frozen popsicle. After years of making the frozen treats for friends, and eventually his own. children, Epperson filed for a patent in 1924.
【1】Who contributed his intelligence to the invention of TV?
A.Philo Taylor Farnsworth
B.Farnsworth's science teacher.
C.Louis Braille.
D.Epperson.
【2】Which invention was accidentally made because of poor concentration?
A.The Electronic Television.
B.The Braille Language.
C.Dollar Sign.
D.Popsicles.
【3】What do the three inventions have in common?
A.They were all designed for the sake of kids.
