二、阅读理解
Coral reefs (珊瑚礁) are an integral part of sea life and sustain it by providing shelter and habitat to various organisms.They also supply and recycle nutrients as well as enable a growing fish population, along with other species, for a healthy and diverse ecosystem.However, the rise in average water temperatures due to climate change has resulted in more frequent and longtime coral bleaching (白化现象) events that damage their health, causing fish and other sea species to abandon them.
In order to restore this delicate ecosystem, scientists from the UK and Australia conducted a study that involved using loudspeakers underwater near damaged coral reefs to make them sound healthy and attract fish, potentially kick starting the natural recovery process of coral reefs and their dependent life forms.The location for this experiment was the Great Barrier Reef in the Coral Sea, found alongside the east coast of Queensland, Australia.The site is noted to have the largest coral reef system in the world.
“Healthy coral reefs are remarkably noisy places — the crackle of snapping shrimp and the whoops and grunts of fish.Young fish concentrate on these sounds when they're looking for a place to settle，” said Steve Simpson, study co author and a professor at the University of Exeter, UK.
By using loudspeakers to copy such sounds, parts of dead coral reefs were found to attract twice as many fish, compared to places where no sounds were played.“These returning fish, are crucial for coral reefs to function as healthy ecosystems.Boosting fish populations in this way could help to kick start natural recovery processes, preventing the damage we're seeing on many coral reefs around the world，” said lead author, Tim Gordon.
1．What causes the phenomenon of coral bleaching
A．Diverse species. B．Noise pollution.
C．Fishing industry. D．Climbing temperatures.
2．What approach is introduced to recover the coral reefs
A．Removing damaged coral reefs.
B．Using loudspeakers to keep fish away.
C．Building new homes for sea species.
D．Playing certain sounds to appeal to fish.
3．Why are Steve Simpson's words quoted
A．To provide some findings of the study.
B．To show the progress of the experiment.
C．To explain reasons for the new approach.
D．To give another solution to the problem.
4．What can we infer from the last paragraph
A．The attempts are in vain.
B．Natural recovery is impossible.
C．Initial success has been achieved.
D．The coral reefs have returned to normal.
三、语法填空
The great outdoors：it's the place to head for when you're in need of peace and quiet, open spaces, beautiful scenery and exercise. 1 a huge mountain range or a local country park, these natural areas are a perfect tonic (补药) for our stressed out lives, and their medical effect is being used more and more 2 (treat) mental health.“Therapy helps people who suffer from depression, 3 (anxious) and stress.It's true that connecting with the natural world 4 (definite) lifts our spirits.Eco therapy doesn't involve taking medicine.Instead, it just develops a person's relationship 5 nature.This natural therapy can take on many forms, such as doing yoga in a forest, gardening or even 6 (hug) a tree.
There are many 7 (benefit) of this “green” therapy, including improving social contact, social and work skills and coping abilities.If we 8 (expose) to the natural elements, then our negative feelings get almost immediately replaced with positive emotions.
Admittedly, eco therapy won't cure everything, but it is 9 option for therapists to use.And as we become 10 (aware) of the causes and effects of mental health, we will better know that help might lie outside our towns and cities, and that nature can give us a helping hand.
四、书面表达
结合课文主题使用本单元词汇与句型, 根据提示写一篇80词左右的短文
1. 近年来, 据研究表明, 雪豹(snow leopard)的数量有了显著的增加。
2. 但是之前, 它们的栖息地被严重破坏了。
3. 很多山坡由于冰雪融化而导致坍塌, 这对雪豹的生存产生了巨大威胁, 致使雪豹数量减少。
4. 保护区随之建立, 以保护这种珍稀的动物。
答案
一、完成句子
1.nor/neither will I
2.with a stick in his hand
3.not until his wife passed away
4.made it possible
5.staring at the mountains in the distance
二、阅读理解
1.D 细节理解题。根据第一段中However, the rise in average water temperatures due to climate change has resulted in more frequent and longtime coral bleaching (白化现象) events that damage their health, causing fish and other sea species to abandon them.可知，气温攀升是导致珊瑚白化现象的原因。
2.D 细节理解题。根据第二段第一句可知，为了恢复这一脆弱的生态系统，科学家们在受损的珊瑚礁附近使用水下扩音器，让它们听起来更健康，从而吸引鱼类。因此应当采用播放某些声音吸引鱼的方法来恢复珊瑚礁。
3.C 推理判断题。根据倒数第二段中Healthy coral reefs are remarkably noisy places — the crackle of snapping shrimp and the whoops and grunts of fish.可知，健康的珊瑚礁是非常嘈杂的地方——虾的噼啪声和鱼的呼噜呼噜声。由此可以推断出，引用Steve Simpson的话是为了解释采用这一新方法的原因。
4.C 推理判断题。根据最后一段第一句可知，通过使用扩音器来模仿这些声音，人们发现部分死去的珊瑚礁比没有声音的地方能吸引两倍多的鱼。由此可以推断出，这一新方法初步取得了成功。
三、语法填空
1．Whether Whether ...or ...意为“无论是……还是……”。
2．to treat 本空用动词不定式作目的状语。
3．anxiety 本空和名词depression和stress并列，都是介词from的宾语，故应用名词anxiety。
4．definitely 本空修饰动词lifts，故应用副词definitely。
5．with 根据句意可知，本空表示人与自然的关系，故应用介词with。
6．hugging 本空和动名词短语doing yoga in a forest及动名词gardening是并列关系，都是举例的一部分，故应用动名词hugging。
7．benefits 根据空前形容词many可知，本空应用名词复数形式。
8．are exposed be exposed to意为“与……接触；暴露于……”，故本空应用are exposed。
9．an 空后名词option是可数名词，在本句中表示泛指“一种选择”，且首字母是元音音素，故应用不定冠词an。
10．more aware 根据句意及下文we will better know that可知，本空应用形容词比较级more aware，表示与过去情况的对比。
四、书面表达
As we all know, the habitat of snow leopards, a first-class national protected animal, was seriously destroyed years ago. Many hillsides collapsed owing to the melting of snow, which threatened their survival and the number of snow leopards decreased sharply. In order to protect them, nature reserves have been set up, where they are well protected. Our efforts have finally paid off. In recent years, according to studies, the number of snow leopards has multiplied dramatically.
