二、阅读理解
“Shine in the dark” dolphins may seem like something straight out of a science fiction movie.However，that is precisely what Newport Coastal Adventures' Captain Ryan Lawler and professional videographer Patrick Coyne witnessed，when they set out to explore the spectacular blue tides that have been lighting up the waters off Southern California's coast since mid April.
The partner scanned the ocean for hours and was returning to shore when they spotted the “electric” dolphins swimming through the bloom of shining plankton(浮游生物)．The videographer，who had seen the phenomenon only once before in a Netflix show，says catching the scenes proved to be a lot harder than he had expected.“For starters，the shining plankton has sweet spots to where it shows up and then fades away，so while on the water，it's impossible to just find it，” Coyne says.“Also，conditions have to be absolutely perfect for the shining plankton to show and for animals to swim through it so we can film it.”
Though witnessing shining sea life is rare，the electrifying blue ocean scenery is a fairly common sight around Southern California between February and September.The phenomenon can be attributed to the presence of millions of plankton，which tend to gather and reproduce in large quantities in the warm coastal waters during this time.
Though a majority of California's red tides are caused by plankton species that do not produce deadly poison，some algal blooms(藻花) can be dangerous for sea animals，especially when they stay for long periods of time.In 2018，an almost year long “red tide” along Florida's Gulf coast caused by the excessive growth of microalgae Karenia Brevis，killed hundreds of fish and other sea animals.
1．What does the underlined phrase “sweet spots” in Paragraph 2 mean
A．A sea plant. B．A lost world.
C．A perfect moment. D．A missing camera.
2．What is the main reason for the sea life shining
A．They absorb the light in the ocean and then reflect it.
B．They are surrounded by millions of shining plankton.
C．They swim through the ocean with electricity in large quantities.
D．They benefit from the warm water to power themselves.
3．What caused the death of some sea animals according to the text
A．Red tides.
B．Human exploration.
C．Warm water.
D．Algal blooms.
4．In which section of a newspaper may this text appear
A．Science. B．Health.
C．Entertainment. D．Education.
三、阅读七选五
As long as we have been on earth，we have used the sea around us.We take from the ocean，and we give to it.
We take fishes from the ocean—millions of kilograms of fish，every year，to feed millions of people. 1 We take minerals from the ocean.One way to get salt is to place seawater in a shallow basin and leave it until it evaporates(蒸发)． 2 Much gold and silver drift dissolved in the waters of the sea，too.But the sea does not give them up by simple evaporation.Other gifts from the sea are pearls，sponges(海绵) and seaweed.Pearls become jewelry. 3 Seaweed becomes food of many kinds—even candy，and ice cream—as well as medicine.Believe it or not，fresh water is another gift from the sea.We cannot drink ocean water. 4 But ocean water becomes fresh water when the salts are removed.In the future，we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food，fertilizer，minerals，water，and other gifts.What do we give the sea？Garbage. 5 Huge as it is，the ocean cannot hold all the water that we pour into it.Dumping garbage into the ocean is killing off sea life.Yet as the world population grows，we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our seas，we might also destroy ourselves.Hopefully，it is not too late.
A．We even use their bones for fertilizer.
B．Some of its contents may cause illness.
C．Natural sponges become cleaning aids.
D．The area of the sea is becoming smaller and smaller.
E．Along with salt，other minerals are left after evaporation.
F．We pollute the ocean when we use it as a garbage dump.
G．We take a lot from the ocean and give little to the sea.
四、概要写作
阅读下面短文，根据其内容写一篇60词左右的内容概要。
Public speaking is the act of speaking to a large group of people in a highly organized manner.Knowing the art of public speaking is very important.The ability to speak confidently and convincingly in public not only will make you stand out while in college，but also will enable you to play an active role in your workplace and community in the future.There are many occasions where you will likely be asked to give a speech，such as in a classroom presentation，at school meetings，graduation ceremonies，awards ceremonies，receptions，or wedding parties.
Public speaking often involves two major stages of work：preparation and delivering.As for the preparation，you should start with an audience analysis and decide on a speech topic and purpose.The more you know and understand about your audience，the better you will choose a topic and prepare the speech.After you analyze your audience and set a speech objective，you need to gather materials to support your idea.Examples，stories，statistics，and testimonies(证明) are four major types of supporting materials.You can gather these materials from the Internet，journals，magazines，books，newspapers，or your personal experience.After you gather enough materials about the topic，you then need to organize them clearly and logically.
The language of a speech tends to be different from that of writing.In a speech，shorter and simpler words and sentences are preferred to long and complex ones so that the listening audience will understand well.Besides，in order to bring emotional responses in the audience，various kinds of rhetorical devices(修辞手法) are often employed to add power to the speech language.
To successfully deliver a speech，you need to do a lot of work as well.For example，you need to make effective use of your voice and body so as to convey your message clearly and vividly.Maybe you also need to prepare some visual aids such as PowerPoint to help your audience understand you well.

二、阅读理解
1.C [词义猜测题。由第二段中的“For starters，the shining plankton...it's impossible to just find it”可知，发光的浮游生物在它们出现和消失的地方都有自己的闪光点，“sweet spots”指的是浮游生物出现和消失的地方，是一个完美的时刻。故选C项。]
2.B [细节理解题。由第三段中的“Though witnessing shining sea life is rare...during this time.”可知，海洋生物发光的主要原因是它们被数百万闪亮的浮游生物包围着。故选B项。]
3.D [细节理解题。由第四段中的“Though a majority of California's red tides...killed hundreds of fish and other sea animals.”可知，造成海洋生物死亡的原因是藻类的繁殖。故选D项。]
4.A [推理判断题。根据文章内容可知，文章介绍了发光的浮游生物，以及说明了浮游生物过度生长会导致海洋生物的死亡。可以推断，这篇说明文可能出现在报纸的科学版面。故选A项。]
三、阅读七选五
1．A [根据上文“We take fishes from the ocean—millions of kilograms of fish，every year，to feed millions of people.”提到我们从海洋里获取许多鱼，当然包括鱼的骨头，这一段在讲鱼对于人类的好处，A项与上文形成递进关系。]
2．E [根据上文“We take minerals from the ocean.One way to get salt is to place seawater in a shallow basin and leave it until it evaporate.”可知蒸发海水可以得到盐，当然也可以得到除盐之外的其他矿物质。E项承接上文，符合题意。]
3．C [根据空前 “Other gifts from the sea are pearls，sponges and seaweed.Pearls become jewelry.”以及空后“Seaweed becomes food of many kinds—even candy，and ice cream—as well as medicine。”故设空处应讲海绵的用途。结合选项，C项承上启下，符合题意。]
4．B [根据上文“We cannot drink ocean water.”我们不能喝海水，由此可知，海水有坏的影响。B项承接上文，符合题意。]
5．F [根据上文“What do we give the sea？Garbage.”我们给了海洋什么？垃圾！由此可知，我们一直在污染着海洋，F项当我们把海洋当作垃圾堆时，我们会污染海洋，承上启下，符合题意。]
四、概要写作
Speaking well in public，which you're often required to do，benefits you greatly.Followings are some tips.Before speech，analyze the audience and fix the theme and target with rich supporting details in an organized way.Besides，simpler expressions and rhetorical devices are preferred to make the speech comprehensible，powerful and emotional evoking.While you're delivering，other aspects like voice variations，body language and visual aids should be considered.
