Ⅴ.阅读理解
What subject do you worry about the most at school Many students worry about maths. Some students can't sleep well the day before a maths exam. Others may feel very nervous during the exam itself. But there might be a way to make the subject less stressful(压力大的)．
“For people who are worried about maths, posture (姿势) makes a big difference，” Erik Peper from San Francisco State University told the Daily Mail. That's right—sitting up straight can help you do better on maths exams.
Scientists tested 125 college students. They asked them to do a simple maths exam while sitting in a slumped over(趴倒的) posture, or sitting up straight. After the test, 56 percent of students said the exam was easier to do if they were sitting up straight.
“Slumping over is a defensive(戒备的) posture. It can bring about bad memories in the body and brain. This can stop you from thinking clearly”， Peper said.
Students who were not nervous about taking the maths exam did not necessarily benefit(受益) from better posture. But they did find that doing maths while slumped over was more difficult, Science Daily reported.
Good posture isn't just helpful for taking maths exams. Sportspeople, musicians and public speakers can all benefit from better posture. When you feel stressed out, you can also try to sit up straight or stand tall. It can help you feel more certain and focus better.
(　　)24.What posture can make people feel less stressed during maths exams
A．Sitting up straight.
B．Hanging your head.
C．Lying on your back.
D．Raising one hand.
(　　)25.What did the scientists ask the college students to do during the test
A．To do sit ups.
B．To count numbers.
C．To think carefully.
D．To sit in different postures.
(　　)26.How many students in the test benefited from better posture
A．All the 125 students.
B．Less than half of them.
C．56 percent of them.
D．None of the students.
(　　)27.The fourth paragraph is written to explain ________．
A．why slumping over makes exams harder to do
B．why slumping over is bad for one's health
C．why some people slump over during exams
D．why people are nervous during maths exams
(　　)28.Which of the following is the best title for the passage
A．Slump Over to Take Exams
B．Sit Up to Do Maths
C．Better Posture for Nervous Students
D．Good Advice for Better Exams
Ⅵ. 阅读短文，根据短文内容回答问题
Tanghulu is fruit covered with sugar on a stick, a traditional snack from northern China. It's also a necessary snack during the Chinese New Year. Recently, in northern China, people welcome the return of spring by holding the Tanghulu Fair(庙会)．
Many Chinese still remember eating tanghulu when they were young. It is said that the fair has a 500 year history. Nowadays, tanghulu is not only a kind of snack, but also a sweet memory of our childhood. Every year, a large number of tanghulu sellers get together to start the delicious tanghulu competition during the Spring Festival holiday. In the past, this traditional snack only used hawthorns(山楂), but now it also uses grapes, oranges, strawberries and so on. But people like hawthorn tanghulu best. It is rich in vitamin(维生素) C and E. Do you know how to make hawthorn tanghulu First, wash the large hawthorns clean, dig the seeds(籽) out, and pierce(串) ten hawthorns on a stick. Then heat the sugar, put the sticks of hawthorns into heated sugar and quickly pull them out. When the sugar on the hawthorns cools down and becomes a candy coat, tanghulu is done. Tanghulu is very popular in China, especially in Beijing. It also makes many foreigners want to taste it.
