And they have a nerve net—which is sensitive to touch—below their outer skin.

三、阅读单选
I’d planned to spend my weekend in the sun, planting flowers outdoors. But that was before the pair of crows (乌鸦). Out of nowhere, they had set up their base camp in our garden.
We first discovered the crows on Friday morning. It was early, and the sound the birds made traveled through our neighborhood. I thought they’d go away soon. But, no. They were getting louder and probably made my neighbors angry nearly as much as us with the noise. I felt a little disappointed.
Then, on Sunday afternoon, I looked out of the kitchen window to see our dog Quatchi watching something on the ground. I found a small coal-black bird in the grass. Its eyes were milky, and it stayed perfectly still as my dog walked towards it. When Quatchi touched his nose to its head, it walked away. I grabbed the dog, locked him inside and came back with my camera.
I never thought that the young would be hanging out on the ground, growing and gaining strength as its parents guarded it from above. The second I saw this little bird I forgave (原谅) the crows.
To be honest, I’ve never been much of a bird person. I also have a healthy respect for birds. They’re basically living dinosaurs (恐龙).
I wish they’d chosen another garden. There are only so many sunny days in Seattle, and I still can’t do any gardening out there. But I’m also thankful that I got to see this little bit of nature. It’s pretty amazing.
The experience has also strengthened my wish to create a beautiful garden that attracts lots of bees, butterflies, and yes, birds. They are welcome here.
26．The arrival of the two crows __________.
A．made the writer’s neighbors thankful B．made the writer’s dog mad
C．was harmful to the writer’s garden D．broke the order of the writer’s life
27．The underlined word “grabbed” in paragraph three probably means __________.
A．hit B．caught C．raised D．protected
28．The writer changed her thoughts on the crows when __________.
A．she planted flowers in her garden B．she locked her dog inside
C．she saw the little bird in her garden D．she thought of living dinosaurs
29．After seeing the little crow, the writer __________.
A．was interested to know its growing progress B．fell in love with the pair of crows
C．could plant flowers outdoors D．decided to help look after it
30．The passage is mainly to __________.
A．show an unpleasant situation B．share a personal experience
C．advise readers to protect birds D．ask advice on dealing with crows
四、阅读判断
阅读短文，根据短文内容判断句子正误。正确的涂A，错误的涂B。
Many countries around the world can be proud of (以……感到骄傲) having the most of something. Canada has the most lakes—around 879, 000 while Russia has the most trees. Forty-five percent of the land there is forest.
When it comes to islands, which country tops the list
Canada is much bigger in size, but it has fewer islands than Sweden, Finland or Norway in Northern Europe. Among them, Sweden gets the first place. Although it is not a big country, it has lots of lakes and islands. Most of the islands there have no people living. Some islands are just 25 square meters. That’s about the size of a one-car garage (车库). Some islands are out of repair. People even can’t remember their names clearly. It’s interesting that if you travel to Sweden, it’s hard to notice you’ve come to a country of thousands of islands. However, there are two main islands which are large enough to provide nice living environment for most Sweden people.
31．The passage mainly talks about the most of something in every country around the world.
32．The number of islands in Australia is eight times more than that in Thailand.
33．According to the list, the top three countries for islands are all in Northern Europe.
34．The writer describes how small some islands are in Sweden by numbering and comparing.
35．We can get the reason why these Sweden islands are out of repair from the passage.
五、阅读回答问题
Once upon a time, in the forest there lived a baby elephant who had no friends. None of the animals wanted to be his friend because he was too large.
One day, a wild fire happened in the forest. The animals ran to safer places. The dry trees caught fire and the fire was sure to go all around the forest. The baby elephant ran to the nearest river, collected much water in his trunk（象鼻）and rushed to the burning trees. He sprayed（喷）the water on the fire. Finally, he put out the fire.
Later, while he was resting after the hard job, all the animals came to him and expressed their thanks for his kind help in time. They were now ready to regard him as their good friend and their hero. They said, “A friend in need is a friend indeed.”
