Once upon a time, the Greens lived in a village. They sent for some workers to build a house with a garden. But after the house was completed, the workers left a rock outside the garden. What’s worse, it caused a lot of trouble.
The son, Jack Green, once asked the father, “Dad, why not move the rock away Many cars and trucks passing by the garden broke down from hitting on the rock by accident.”
“Oh, you mean that large rock It’s 1.4 meters wide and it must be very heavy. You know it’s lots of work if you want to do that. As long as I pay attention to driving, the rock won’t be a problem,” answered the father.
Time went quickly. Jack got married and became a father. One day, his wife shouted at him, “Jack, I can’t stand the rock out there any longer! My truck hit on the rock again. We must move it away!”
Jack replied to his wife, “Forget it! If we could move the rock away at my young age, how can it remain here now ”
Jack’s answer is just like adding oil to a fire. His wife got angrier and thought to herself, “My truck will never hit on the rock another time. I will do that on my own.” The next morning, Jack’s wife carried a hoe (锄头) and a large bucket (桶) of water towards the big rock. She really wanted to dig the whole rock out so she could look at it carefully to find out how large it was. First, she watered the earth around the rock. Then, she stuck her hoe into the earth and began to dig. She had expected that it would take at least half a week to dig it out, but it only took her one day. In front of the whole rock, she felt surprised. The part that Jack and his father had seen was most of the rock. The part under the earth was not as big as they thought. They had been fooled by its look for such a long time.
Sometimes what’s in our way is not the rock in the eyes but the rock in the heart.
根据短文内容判断正、误。 (注意：正确的涂“√”，错误的涂“×”)
26．Jack’s father thought moving the rock was a lot of work because it was very heavy.
27．Jack and his father had moved the rock a little bit before but failed.
28．Jack’s wife hit the rock with her car more than once.
29．It took Jack’s wife half a week to dig out the rock.
30．The story tells us that we should not be afraid of difficulties just because they seem big from the outside.
“You are just like your mother.” This is often said by many. As we grow older, we may notice that we’re getting more like our mother. Yet surprisingly, new research has found that most people are more similar to their father.
A team of scientists from the University of North Carolina School of Medicine in the US found that we inherit (继承) the same number of genes (基因) from mother and father. But we use more of the DNA we inherit from our father.
The study helps us to partly explain who we are. And more importantly, it helps us to find out whether we are likely to develop diseases (疾病). For example, if we inherit the gene for a disease from our mother, it may not be as strong as if we had inherited it from our father.
We know that there are 95 genes influenced by our parents, said lead researcher Professor Fernando Pardo-Manuel de Villena. These are called imprinted genes (印记基因). But now, the study has found that there are thousands of other genes that have come from our parents.
For the study, the scientists chose three different kinds of mice with different genes. The mice then gave birth to nine babies each. When they all reached adulthood (成年), the team then measured (测量) every single gene of their DNA．
They found an imbalance (不平衡) that headed toward their father. Villena also said that the recent study was the first to show that mammals (哺乳动物) are more similar to their fathers than mothers. “This is an exceptional new research finding that opens the door to a complete new area of exploration in human genetics,” he said.
根据短文内容选择最佳答案。
31．What is the new finding
A．We are born to look more like our father.
B．We use more of the DNA that we inherit from our father.
C．We have the same chances to be more like our mother or father.
32．What’s the main idea of Paragraph 3
A．We are supposed to be stronger than our parents.
B．We don’t inherit the gene of a disease from our mother.
C．The finding helps us find out possible diseases.
33．In the fifth paragraph (段落), the word “they” refers to (指的是) ________.
A．the three mother mice B．the nine baby mice C．the scientists
34．The underlined (划线的) word “exceptional” in the passage means “________” in English.
A．unusual and excellent B．small and unlucky C．hopeless and simple
35．Where would you most probably find this article

六、任务型阅读（本大题共2小题）
What’s the fastest and most effective (有效的) way to learn What’s the secret to remembering what you learn
The “learning pyramid (金字塔)” suggests that most students only remember 5% from lectures (讲授). They remember 10% of what they read from textbooks, but get nearly 90% of what they learn by teaching others.
The most common form of teaching others is Peer Tutoring (同伴辅导). It is a really fun and helpful way to learn. It means that we teach each other and help each other. To do peer tutoring, we can take turns being the teacher. The teacher explains a subject, and the student tries to understand it. If the student doesn’t get it right away, the teacher helps them understand it. It’s important to ask questions and give positive feedback (积极反馈) to each other.
Peer tutoring is really good for our memory by making us think deeply. When we teach others, we have to think about it really hard to make sure we explain it right. And when others teach us, we need to think carefully and try to understand what they’re saying. This helps us learn better.
So if you’re looking for a way to make learning more fun and effective, try peer tutoring! You’ll be surprised at how much you can learn from each other.

Dear Mike,
I’m glad to hear from you. You asked about my English homework, so I’d like to share some details with you.
Our English homework usually includes reading, writing, and grammar exercises. For example, we often read short stories and answer questions to improve our understanding. Writing tasks are also common, such as writing essays or letters. As well as this, we practice grammar to avoid mistakes in our sentences.
I find these tasks very helpful. Not only do they help me improve my skills, but they also make me more confident in using English. I hope this gives you a clear idea of my homework.
Yours,
Li Hua
