二、完形填空
Jellyfish are badly named. They are neither a fish nor made of jelly. Instead, their bodies are 11 95% water and 5% solid matter. They have been in existence for at least half a billion years. Yes, they are 12 than dinosaurs. Surprisingly, they don’t have a brain, a heart, or lungs（肺）. You may wonder how they can possibly survive without these vital organs, but 13 is for the best. They don’t have lungs because their skin is 14 thin that they can absorb（吸收）oxygen through it. They don’t need a heart to pump blood because they don’t have any. And they have a nerve net—which is sensitive to touch—below their outer skin. They respond to the changes in their environment using signals from the nerve net, so they don’t need a 15 to process complex thoughts.
Their variety is nearly endless. Most of them are umbrella—shaped and have tentacles（触角）. Some jellyfish have very long tentacles. 16 , they never get tangled up or sting themselves. That’s because the tentacles are very slippery（滑的）and will only sting other animals. Most jellyfish have 17 or no vision, but they can detect light and ocean currents, which helps them to navigate and move. A few species can also recognize colour and have a 360-degree view of their environment.
Jellyfish come in all 18 , from 0.5 millimeters to the giant Nomura’s jellyfish, which can measure up to two meters in diameter and weigh over 200 kilograms. While jellyfish are beautiful, they can also be 19 . Some jellyfish toxins can be deadly to humans, such as those from the box jellyfish and the Australian Irukandji, but deaths are relatively rare given the number of jellyfish-sting victims every year. In any case, it’s better to stay 20 the way of any jellyfish you may see! You can go swimming with dolphins, but you definitely want to think twice before swimming with jellyfish.
11．A．made in B．made of C．made from D．made up of
12．A．older B．bigger C．smaller D．younger
13．A．nothing B．anything C．something D．everything
14．A．so B．too C．such D．very
15．A．lung B．brain C．heart D．tentacle
16．A．But B．Anyway C．However D．Otherwise
17．A．good B．much C．little D．a little

三、阅读单选

The great white shark（鲨鱼）is one of the most dangerous animals in the world. It can grow up to 7 meters long and weigh 2,100 kg. It has five rows of up to 3,000 very white, very sharp teeth. It needs them because the great white shark is a carnivore. It will eat almost anything that swims in the sea, from fish to dolphins to other sharks. Oh, and people, too. So, imagine how Rob Howes felt when he faced one of these terrifying animals off the northern coast of New Zealand.
Rob was swimming with his 15-year-old daughter, Niccy and two of her friends. They were enjoying the crystal-clear water when they noticed some dolphins（海豚）swimming up to them. It is not surprising to see dolphins in the waters there, and they often swim near humans. But these dolphins were not there for fun. They were swimming around the four humans in smaller and smaller circles. It seemed like they were gathering up the swimmers. Also, the dolphins were hitting their tails on the water. Were they trying to tell them something That was when Rob saw the great white shark.
It was very close—only a few meters away. It wasn’t a big one, but at 3 meters long, it was big enough. It was swimming towards them, gliding through the water, but when it saw the dolphins, it turned and swam away. Rob realized that the dolphins had saved their lives. Had they known there was a shark nearby and decided to protect them The dolphins followed the swimmers until they got safely back to shore（岸）. Rob and the others were very lucky that day. Some people pay lots of money to swim with dolphins. Rob swam with dolphins for free, but he also had a great white shark with him!

Over time, the cuckoo (布谷鸟) has learned to get other birds to care for its babies. The cuckoo is an amazing bird. Most birds lay their eggs and look after them until their babies hatch out. Then they feed their babies until they are ready to leave the nest.
Some birds are not such good parents. Cuckoos lay their eggs in the nest of other birds and do not care for their own babies. They get other birds to act as the parents. The other birds raise the young cuckoos as well as their own babies!
If the cuckoo egg hatches first, the baby cuckoo will often push the other eggs out of the nest so that it can get all the attention of its new mother. The young cuckoo sometimes even push the other babies out of the nest. The young cuckoo has a loud cry and is often bigger than the other baby birds, it will take all the food and the space in the nest.
If the cuckoo lay around 25 eggs each year in the nests of other birds. This means that many other birds spend all their time looking after young cuckoos instead of their own babies. Some birds have learned to recognize the cuckoos’ eggs and they push them out of their nests. But the cuckoos have also found ways of fooling (欺骗) the other birds. They can change their eggs to make them look just like the other birds’ own eggs.

Whether you’ve noticed it or not, fewer and fewer bees are around us now. About one quarter of the world’s 20,000 bee species (品种) have disappeared since 1990.
There are many reasons for that, including too much use of pesticides (杀虫剂), loss of plants and human activities that damage (破坏) their living places. But the main reason is the climate change, which is changing the bees’ environments in a faster way than they are able to get used to.
A map of where bees live across the world was just made by scientists from China and the US. To help people know about bees and protect them better, they tried to find out different species of bees in different areas. According to the map, there are more species of bees in the north half than in the south half of the earth, and more in dry warm areas than in wet forest areas.
In fact, bees are important contributors to humans and the whole world. When bees are flying from one place to another, they are helping many plants to pollinate (授粉). In other words, without bees, fresh fruit and vegetables would be fewer and fewer around the world. Therefore, we human should make our efforts to protect bees.
As for what to do to help, plant some plants to attract bees to your garden. If you see bees around you, take some photos and post them on the Internet so scientists can help find out where bees live and how bees move. We can come up with more ideas to save bee populations around the world.
30．How many bee species have disappeared since 1990
A．About 5,000. B．About 10,000. C．About 20,000. D．Over 20,000 .
31．Which is NOT a reason for the drop of bee population
A．Wide use of pesticides. B．Worse living places.
C．The fast climate change. D．Fewer fresh fruit and vegetables.
32．Which does the bee map tell us
A．Bees like living in wet places. B．Bees are protected better than before.
C．Where different bee species live. D．The south half of the earth has more bee species.
33．What does the underlined word “contributors” in paragraph 4 mean
A．Makers B．Helpers C．Finders D．Carriers
34．What is the last paragraph about
A．Ways of bee protection. B．Changes of bees’ living environment.
C．Bee populations around the world. D．The importance of protecting bee species.
D
A desert(沙漠) is a difficult place for animals to live, and some have unusual ways of making a living. The Texas lizard has a strange way to keep itself safe. When a predator(掠食动物) gets too close, blood goes out from the lizard’s eyes. Then it breathes in much air to make its body look bigger. Another interesting desert animal is the javelina. To make a predator afraid and run away, the javelina bravely faces the animal. It makes a big noise with its teeth. It raises the hard hairs on its back to make itself look bigger. The javelina also gives off a strong smell as a warning when it is afraid. This smell is so strong that javelinas are also called “smelly pigs”. Javelinas keep safe by staying close to their family, so there’s a good chance they can make a predator change its mind!
You might think a rain forest would be easier to live in than a desert. After all, there's plenty of food and water in a rain forest. But that also means a lot of animals live there. Being able to climb trees is a useful skill in the rain forest. It allows an animal to keep away from predators. The sloth spends most of its life in the treetops. Its strong, curved claws(爪子) help it climb and hang upside down from branches. The sloth also moves very slowly. It does this so it’s not noticed. The aye-aye lives only in the rain forest of Madagascar, near Africa. The aye-aye is a night animal. This helps it to stay safe from daytime predators. However, the number of the aye-aye keeps going down and they may die out. People have hunted it because they think it brings bad luck. Also, much of the rain forest in Madagascar has been cut down, which has destroyed the aye-aye’s home. Today there are laws(法律) to keep people from killing it.
35．What is the passage mainly about
A．What the animals in the desert look like.
B．How the animals in the rain forest find their food.
C．How the animals in the desert and in the rain forest stay safe.
D．What animals are in danger of losing their living environment.
36．How does a lizard protect itself when a predator gets too close
A．It climbs trees. B．It makes a big noise.
C．It gives off a strong smell. D．Blood goes out from its eyes.
37．What can we learn from the passage
A．The aye-aye is a welcome animal in Africa.
B．There is no food, no water and no danger in the desert.
C．The lizard and the javelina can make their bodies look bigger to keep safe.
D．It is really dangerous for the sloth to live in the forest no matter where it is.

12．句意：是的，它们比恐龙出现的还早。
older更久的；bigger更大的；smaller更小的；younger更年轻的。根据前文“They have been in existence for at least half a billion years.”可知，水母在地球上存在至少有5亿年了。而恐龙在地球上生存时间约1.65亿年。所以水母比恐龙存在的时间更久。故选A。
13．句意：你可能想知道没有这些关键的器官，它们怎么能生存的，但一切都是最好的安排。
nothing没什么；anything任何东西；something一些东西；everything每件事，一切。根据后文解释“They don’t have lungs because their skin is … thin that they can absorb（吸收）oxygen through it. They don’t need a heart to pump blood because they don’t have any. And they have a nerve net—which is sensitive to touch—below their outer skin. They respond to the changes in their environment using signals from the nerve net, so they don’t need a … to process complex thoughts.”可知，由于水母自身生长的特征，它们的皮肤可以呼吸，它们没有血液所以没有心脏，它们有神经网可以感知外面的环境。因此这里表达的是“一切的安排都是最好的”。故选D。

lung肺；brain大脑；heart心脏；tentacle触角。根据“Surprisingly, they don’t have a brain, a heart, or lungs（肺）”可知，水母是没有大脑，心脏和肺的，前面已经介绍为什么没有肺和心脏。这里是介绍没有大脑是怎么感知外界的。故选B。
16．句意：然而，触角永不缠绕在一起或刺到自己。
But但是；Anyway不管怎样；However然而；Otherwise否则。根据前文“Some jellyfish have very long tentacles”可知，一些水母有很长触角，“但是”触角是不会缠绕在一起或者刺到他们自己，这里表示转折，横线后有逗号。故选C。
17．句意：大部分水母几乎没有或者就是没有视力，但它们可以察觉到光和洋流，这能帮助它们行进和移动。
good好的；much许多；little少，几乎没有；a little一点点。根据后面的“… or no vision, but they can detect light and ocean currents,”可知，它们不是通过视力感知光和洋流的。因此视力是“几乎没有”。故选C。
18．句意：水母大小不一，从0.5毫米到直径2米多，体重重达200公斤多的巨型越前水母。
types类型；sizes尺寸，大小；looks面貌；colours颜色。根据后文“from 0.5 millimeters to the giant Nomura’s jellyfish, which can measure up to two meters in diameter and weigh over 200 kilograms.”可知，这里说的是水母的“大小”。故选B。
19．句意：尽管水母很漂亮，但是它们也很危险。
pleasant令人愉快的；dangerous危险的；surprising令人惊讶的；interesting有趣的。根据文“Some jellyfish toxins can be deadly to humans”可知，水母有毒且对人类是致命的。所以水母应该是“危险的”。故选B。
20．句意：在任何情况下，最好要远离任何你看到的水母。
in the way阻挡，妨碍；on the way在路上；away远离，后加from；out of the way远离。
根据前文“Some jellyfish toxins can be deadly to humans, such as those from the box jellyfish and …”可知，水母毒素对人类是致命的，因此要“远离”它们。故选D。

Adoption or Purchase
Animal rescue volunteers suggest that people who plan to keep pets should choose to adopt stray pets instead of buying them. People hold different views towards this issue.
Some people strongly agree with the volunteers, thinking that adoption is better. On one hand, some hidden danger caused by those homeless animals can be reduced. If stray pets are adopted, they will be less likely to hurt people. On the other hand, it is often free to adopt stray pets so money can be saved.
On the contrary, there are also some people against adopting stray pets. Because the health condition of homeless pets is unclear, there are risks to take them home. In addition, people can have much more choices to pick the breeds they like if they choose purchase rather than adoption.
From my point of view, adoption is a better choice. If we worry about whether the stray animals are healthy, we can take them to have a physical examination before we make the decision.
