2017秋英语（人教）优生巩固题：必修4Unit1含解析
Task 1：阅读下列短文，从每小题后所给的A、B、C、D四个选项中，选出最佳选项。
(2015·陕西，C)The production of coffee beans is a huge，profitable business，but，unfortunately，full-sun production is taking over the industry and bringing about a lot of damage.The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of certain animals and birds，and even disturbs the world's ecological balance.
On a local level，the damage of the forest required by full-sun fields affects the area's birds and animals.The shade of the forest trees provides a home for birds and other species(物种) that depend on the trees' flowers and fruits.Full-sun coffee growers destroy this forest home.As a result，many species are quickly dying out.21cnjy.com
On a more global level，the destruction of the rainforest for full-sun coffee fields also threatens(威胁) human life.Medical research often makes use of the forests' plant and animal life，and the destruction of such species could prevent researchers from finding cures for certain diseases.In addition，new coffee-growing techniques are poisoning the water locally，and eventually the world's groundwater.【来源：21·世纪·教育·网】
Both locally and globally，the continued spread of full-sun coffee plantations(种植园) could mean the destruction of the rainforest ecology.The loss of shade trees is already causing a slight change in the world's climate，and studies show that the loss of oxygen-giving trees also leads to air pollution and global warming.Moreover，the new growing techniques are contributing to acidic(酸性的) soil conditions.
It is obvious that the way much coffee is grown affects many aspects of life，from the local environment to the global ecology.But consumers do have a choice.They can purchase shade-grown coffee whenever possible，although at a higher cost.The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.

Without a second thought，the woman joined the Welty party.When her dinner partner showed up，she also pulled up a chair.【出处：21教育名师】
“They began telling me all the news of Mississippi，” Welty said.“I didn't know what my New York friends were thinking.”
Taxis on a rainy New York night are rarer than sunshine.By the time the group got up to leave，it was pouring outside.Welty's new friends immediately sent a waiter to find a cab.Heading back downtown toward her hotel，her big-city friends were amazed at the turn of events that had changed their Big Apple dinner into a Mississippi state reunion(团聚)．
“My friends said：‘Now we believe your stories，’” Welty added.“And I said：‘Now you know.These are the people that make me write them．’”
Sitting on a sofa in her room，Welty，a slim figure in a simple gray dress，looked pleased with this explanation.
“I don't make them up，” she said of the characters in her fiction these last 50 or so years.“I don't have to.”
Beauticians，bartenders，piano players and people with purple hats，Welty's people come from afternoons spent visiting with old friends，from walks through the streets of her native Jackson，Miss.，from conversations overheard on a bus.It annoys Welty that，at 78，her left ear has now given out.Sometimes，sitting on a bus or a train，she hears only a fragment(片段) of a particularly interesting story.

译文：在返回市区宾馆的途中，韦尔蒂的大都市的朋友们惊讶于他们活动的转变，他们的聚会早已由纽约式的宴会变成了密西西比人的地方性团聚。
2．Beauticians，bartenders，piano players and people with purple hats，Welty's people come from afternoons spent visiting with old friends，from walks through the streets of her native Jackson，Miss.，from conversations overheard on a bus.
分析：句中的“Beauticians，bartenders，piano players and people with purple hats”与“Welty's people”构成同位关系，三个from介词短语与come连用，表明小说中人物角色来源的多面性。
译文：Welty小说中的角色——美容师、酒吧招待、钢琴演奏者及那些戴着紫色帽子的人——源自于她与老朋友共度的下午，源自于她在土生土长的密西西比州杰克逊城的大街小巷散步的过程中，还源自于她在公交车上无意间听到的闲谈。
Task 6：经典句式背诵
1．By the time the group got up to leave，it was pouring outside.当他们起身离开的时候，外面下着倾盆大雨。
2．Sitting on a sofa in her room，Welty，a slim figure in a simple gray dress，looked pleased with this explanation.
