记牢　知识再梳理
(1)连接并列成分,如名词、形容词、动词、介词短语等,意为“又,和,也;不但……而且……,既……又……”,强调的是as well as 前的成分,谓语动词的数采用就远原则,即与as well as前面的主语的人称和数保持一致。
(2)意为 “除了……还”,相当于besides、in addition to、apart from。后面通常接名词或v.-ing形式,尤其是当其位于句首时。
(3)表示同级比较,意为 “和……一样好”,此时well是副词。

2....be said to have done sth
教材原文　Alexander the Great and Marco Polo were said to have visited such a tree in India.

感知　语言先输入
①The English short movie is said to be not only meaningful but also interesting.(影评)
②Many people were said to have witnessed the strange lights in the sky last night.(场景描写)
记牢　知识再梳理
本句使用了...be said to have done sth结构,意思是“据说……已经做了某事”,相当于“It was said that...”。该句可以改写成:It was said that Alexander the Great and Marco Polo had visited such a tree in India。
(1)在“sb/sth be said to do sth”结构中,其不定式根据需要有时态和语态的变化:
be said to be+adj./n.　据说(是)……
be said to do sth 据说要做某事
be said to be doing sth 据说正在做某事
be said to have been done 据说某事已经被完成
(2)类似句型还有:It is reported that...据报道……;It is supposed that...据猜测……;It is hoped that...希望……;It is well known that...众所周知……。
(3)在句型“It is suggested that...据建议……”中,that引导的从句中谓语使用“(should)+动词原形”。
运用　单句语法填空/同义句转换
①Though his heart is said ________________(be) weak,he seems perfectly healthy.
②He is said ____________________(write) a novel about China at present.
③It is suggested that we ________________(keep) a balanced diet in daily life.

⑦It is said that the early European playing-cards were designed for entertainment and education.
→The early European playing-cards ____________________________

3.句型公式:动词-ing形式(短语)作伴随状语
教材原文　Some trees make clicking noises when there is not enough water,indicating drought is arriving.　
当没有足够的水分时,一些树会发出咔嗒声,这表明干旱即将来临。
感知　语言先输入
①The students finally crossed the deep water safely,expressing their heartfelt gratitude to their teachers.(动作描写)
②Hearing what their mother said,so delighted were the twins that they gave kisses on their mother’s cheeks.(情感描写)
记牢　知识再梳理
本句中indicating是动词-ing形式作伴随状语,动词indicate和句中主语Some trees在逻辑上是主谓关系,且该动词和句中谓语动词make同时发生,即表示主动的、正在进行的动作。
动词-ing形式(短语)在句中作状语:
(1)动词-ing形式(短语)作状语可以表示时间、条件、原因、让步、结果、方式、伴随等,且动词-ing形式(短语)与句中主语有逻辑上的主谓关系。
(2)当动词-ing形式(短语)的动作发生在主句谓语动词之前时,要用动词
-ing形式的完成时having done。
(3)作状语的分词(短语)相当于一个状语从句。
运用　单句语法填空/完成句子
①When I came home,I found my father sitting in the armchair,____________ (read) a magazine.

Diego Carde osa has loved sharks ever since he was a child.The Colombia native was never afraid of them when he visited his beloved beach.Instead,he was fascinated with how sharks moved through water using their fins (鳍).It’s no surprise that he became a marine (海洋的) biologist.
Concern grew as Carde osa learned about the serious state of sharks worldwide.The International Union for the Conservation of Nature reports a shocking rise in the extinction threat to shark species,now affecting 35%,up nearly 50% in a decade.Overfishing stands as the main cause,driven by demand for shark meat and fins.
“They are being killed at a rate that cannot survive in the future,” said Carde osa.“As soon as I realized they were going through a conservation crisis,I wanted to help what I love the most.”
Scientists worry the sharks’ dropping numbers could bring ecological disaster as they play a number of key roles in the ocean.Unlike many fish,sharks take a long time to reproduce.Fisheries kill about 100 million sharks a year,according to the non-profit Save Our Seas.
Many sharks end up as bycatch when long lines and nets unintentionally catch them.Today,Carde osa fights against the illegal shark trade as a Distinguished Postdoctoral Scholar at Florida International University.His innovation—a portable DNA kit like a small red box—plays a key role in identifying shark species and their origins in major ports globally.This breakthrough has greatly improved law enforcement (实施) efforts in ports like Hong Kong,where the amount of seized shark fins has risen from five to a hundred tons annually since the kit’s introduction.
Carde osa’s efforts extend beyond sharks,aiding authorities in stopping trafficking of other endangered species like European eels and South America’s Matamata turtles.His commitment earned him recognition from international criminal police organization.
【语篇解读】　本文是一篇新闻报道。文章主要讲述了Diego Carde osa从小热爱鲨鱼,长大后成为海洋生物学家,致力于保护鲨鱼和其他濒危物种的故事。
4.What led to Diego Carde osa’s profession
A.His great interest in sharks.
B.His surprise at sharks’ value.
C.His concern for shark extinction.
D.His childhood love for oceans.

A.Climate change. B.City construction.
C.Natural disasters. D.Business fishing.
解析　细节理解题。根据第二段中“Overfishing stands as the main cause,driven by demand for shark meat and fins.”可知,鲨鱼物种面临灭绝威胁的主要原因是商业捕鱼,故选D项。
√
6.What could happen if sharks continue to decrease in numbers
A.There will be fewer attacks on tourists.
B.More fish species might become endangered.
C.Marine ecological balance could be destroyed.
D.Fishing industries would face less competition.
解析　细节理解题。根据第四段中“Scientists worry the sharks’ dropping...number of key roles in the ocean.”可知,如果鲨鱼的数量继续减少,海洋生态平衡可能会被破坏,故选C项。
√
7.What is the function of Diego’s DNA kit
A.It reduces shark fin sales.
B.It aids in species identification.
C.It changes law enforcement.
D.It meets demand for shark products.
解析　细节理解题。根据第五段中“His innovation—a portable DNA kit...their origins in major ports globally.”可知,Diego的DNA试剂盒的功能是有助于物种鉴定,故选B项。

Animals and people have been living together for thousands of years,but the past 100 years have been extraordinary in the amount of change in those relationships.In the last 100 years,people have markedly changed their perceptions (认知),their relationships,and their uses of animals and animal products.Many of these changes have occurred in our lifetimes.
Some of us grew up on farms and had considerable contact with livestock and wildlife.We knew that dairy cows were kept to provide milk and meat.Beef cattle and pigs were slaughtered (屠宰) to provide food,and chickens provided eggs as well as meat.Wildlife,living on the farm or nearby,was often hunted by farm families to provide meat and skins.Even though we understood,or perhaps because we understood the primary role of animals in our lives,we were often in a close relationship that gave us a perspective of our interdependence and the
nature of life and death in our ecosystem.Today,less than 1% of families in the US are engaged in raising livestock;few children have seen or experienced the cycle of life and death of livestock or plants;few know first-hand where their milk,cheese,eggs,meat, vegetables and fruit actually come from.
One hundred years ago,nearly all dogs were kept for herding, pulling power,hunting,tracking,or protection and were seldom allowed in the house,almost never in the bedroom.Today most dogs in the US are kept in the house for companionship and only occasionally kept for work.Current studies also show that 60% to 80% of dogs sleep with their owners at night in the bedroom,either in or on the bed.This indicates the closeness of a relationship and it is a major change in our attitudes towards treating pets as family.Today the media and most people consider pets as part of their families.
Today we have multinational and multicultural recognition of the mutual benefits of the human-animal bond to health and spirit.Animals offer companionship—someone to talk to who will not criticize.They are living responding beings to touch or hug with emotion.Animals keep us alert and help fulfill our need to nurture and comfort others.
【语篇解读】　本文是一篇说明文。文章主要介绍了人类与动物之间关系的历史变迁,以及这些变化背后的一些社会和文化因素。
8.Which of the following is NOT a factor contributing to the changes in people’s attitude towards animals
A.The decline in the number of farming families.
B.The increased use of technology in animal breeding.
C.The lack of children’s exposure to animal life cycles.
D.The changes in the use of animals in daily lives.
解析　推理判断题。根据文章第二段内容可知,农业家庭数量的减少和儿童缺乏对动物生命周期的接触是导致人们对动物态度变化的因素。根据文章第三段内容可知,过去用来放牧等的狗现在被视为家庭的一部分。由此可知,动物在日常生活使用中的变化,也是导致人们对动物态度变化的因素。只有选项B未被提及,故选B项。
√
9.What can be learned about dogs according to paragraph 3
A.In the past,dogs can be kept as a companion.
B.Dogs are good helpers to hunt for small animals.
C.Dogs can be trained to work as a safety guard.
D.Nowadays dogs are not as helpful as before.
解析　推理判断题。根据文章第三段内容可知,现在,狗可以被当作伙伴养着;过去狗可以被训练成安全警卫,但没有说狗可以帮助打猎小动物,故选C项。
√
10.What benefits do animals provide to humans nowadays
A.Animals provide food and clothing for human beings.
B.Animals offer companionship and emotional support.
C.Animals are primarily used for entertainment purposes.
D.Animals help fulfill human desires for power and control.
解析　推理判断题。根据文章第三段“Today most dogs in the US...consider pets as part of their families.”和最后一段“Animals offer companionship...and comfort others”可知,动物给人类提供的是陪伴和情感支持,故选B项。
√
11.Which of the following is the best title for this passage
A.The changing status of human-animal bond
B.Hunting for food:the nature of life and death
C.The process of domesticating dogs as pets
D.Livestock farming:a thing of the past
解析　标题归纳题。通读全文,尤其是由文章第一段可知,整篇文章讨论了人与动物关系的变化,特别是在过去100年间的变化,包括人们对动物的态度、动物在人们生活中的角色以及动物为人类提供的福利等方面。因此,最合适的标题是选项A “人与动物关系的变化状况”,故选A项。
√
Ⅱ.七选五(每小题2.5分,共12.5分)
Even when you have a garden,you can still take a break from time to time!Here are some tips to help make sure your garden crops survive when you go away in summer for a little while.
__1__ Automated watering systems might be the first thing that crowds into your mind.They usually work at set times to keep your plants from thirst.But in smaller spaces you might consider different solutions like adding watering globes and water bottles placed upside down in beds or planters.__2__ Work out rough water needs for specific plants and add cloth,if necessary,to absorb water from a container into the soil at the base of plants.With calculation and enough watering solutions,most of your plants will survive.
In dry areas,it can be beneficial to reduce the amount of water your crops will require while you are away.__3__ This could potentially help you gain a little more time.Think about how you can still ensure enough daylight for crops while also providing some shade for them during the hottest part of the day.
Pests could also be an issue if you are not there.Taking an integrated pest management approach is the best policy.__4__ Remember,biodiversity is key and you need some pests to be present in order to attract the things that eat them and keep their numbers down.__5__ Covering crops with netting or row covers could prevent a major crop disaster,so adding additional protection could be a good idea.
A.Work with nature,rather than fight it.
B.You might also water the plants more before you leave.
C.Water will often be the biggest concern in your absence.
D.Shade specific parts of your garden to reduce wetness loss.
E.Combine plants and add companion plants for beneficial interactions.
F.These allow water to be released slowly to provide water for your plants.
G.Sometimes,however,barriers may be required to keep crops safe from pests.
【语篇解读】　本文是一篇说明文。文章主要就夏日不在家时人们如何保住菜园里的植物给出了几条建议。
1.C　 [根据下文“Automated watering systems might...upside down in beds or planters.”可知,自动浇水系统可以帮助你在固定时间浇水,防止植物干枯,而在较小的空间你可以考虑安装倒置的洒水球和水瓶来解决浇水的问题。由此可知,C项“你不在的时候,水通常是最大的问题。”引出下文对浇水措施的介绍,故选C项。]
2.F　 [根据上文“But in smaller spaces you might...down in beds or planters.”可知,在较小的空间里,可能会考虑不同的解决方案,F项“这些方法可以让水慢慢流出来,给你的植物提供水分。”承接上文,说明这些措施的好处,选项中的These指代上文中提到的different solutions,故选F。]
3.D　 [根据上文“In dry areas,it can be beneficial...require while you are away.”可知,在干燥区域,在你离开期间减少作物所需的水量是有益的。D项“遮蔽菜园的特定区域,以减少湿度损失。”承接上文,提出具体的解决办法,并引出下文这样做的好处“这可能会帮助你赢得更多的时间。”,故选D项。]
4.A　 [根据上文“Pests could also be an issue...approach is the best policy.”可知,要采取措施应对虫害。A项“与大自然合作,而不是与之抗争。”衔接恰当,说明应对虫害的方法是与大自然合作,并引出下文具体的解释“记住,生物多样性是关键,你需要一些害虫来吸引吃它们的生物,以降低它们的数量。”,故选A项。]
5.G　 [根据上文“Remember,biodiversity is key and...and keep their numbers down.”可知,利用与自然协作的方式来抵抗虫害。并结合下文“Covering crops with netting or...protection could be a good idea.”可知,G项“然而有时,需要设置屏障物来确保作物不受病虫害。”引出下文,与上文构成递进关系,故选G项。]
