It turned out that it was my dad that had made the mistake when he booked the   (14)  . The flight was flying to San José, Costa Rica, not San Jose, California. I got close to the flight stewardess (女乘务员), who   (15)   her leader that they got a young man on the wrong plane. Luckily, a   (16)   Costa Rican lady lent me her iPad with Wi-Fi. I sent a quick email to my parents and teachers. "I just boarded (登上) the   (17)  plane and Iˈm flying to Costa Rica. Yeah, me! Iˈm not joking," I wrote. "Please   (18)  as soon as possible.

As there was nowhere to go, I   (23)   spending the night on a bench in the airport. I   (24)  arrived in the right San Jose 28 hours after I had left New York.

This is surprising since bees have very small brains. Studies have shown that only humans and a few animals such as monkeys and some birds understand zero. And humans usually donˈt understand it until theyˈre around four years old. But bees are smarter than they look. Scientists already knew that bees could count up to four. They also knew that bees could “talk to” each other. By dancing in some ways, bees could tell other bees how far away the food was and in what direction. Scientists at RMIT University in Australia came up with a smart way to test whether bees understood the concept (概念) of zero. They prepared some cards with different numbers of shapes on them. First, they had to train the bees by giving them sugar water to make them choose the cards with fewer shapes on them. They put something sour (酸的) under the cards with more shapes on them. Soon the bees knew there was sugar water under the cards with fewer shapes. After about 40 tests, the bees learned to choose the cards with different numbers of shapes. Then came the interesting part. The scientists put a card with nothing on it. Even though they had never seen it, the trained bees chose the blank (空白的) card. This showed that they knew that “zero” or “none” meant less than “some”. Beesˈ brains are about 1/86,000 the size of human brains. How are they able to do so much with such a small brain? Scientists want to study more bees to find out more. Many are now trying to create machines that can “think” like bees. By learning how the beesˈ brains work, they may be able to use some of those ideas to teach computers and robots some new tricks. 26.What can we learn from Paragraph 1? A. Bees are smarter than monkeys. B. Most animals can count up to four. C. Humans can understand zero since birth. D. Dancing is a form of bees’ communication. 27.Why did the scientists use sugar water? A. To train the bees to choose the cards with more shapes. B. To check if bees could tell sweetness from sourness. C. To test if bees understood the meaning of numbers. D. To encourage the bees to choose the cards with fewer shapes. 28.The interesting result of the test was that ________. A. the bees chose the blank card B. the bees landed on the sugar water C. the bees flew towards the sour water D. the bees chose the cards with some shapes 29.The underlined word “tricks” in the last paragraph is closest in meaning to “________”. A. numbers B. skills C. ideas D. goals 30.Which is the best title for the passage? A. Bees Are in Need of Protection. B. Bees Are Important to Humans. C. Bees Know the Meaning of Zero. D. Bees Have Funny Social Activities. 四、阅读七选五：本大题共5小题，共10分。 For many Chinese parents, itˈs very difficult to get kids to study for tests. Here are some suggestions.   (31)   Set a timetable(时间表) to keep doing the same activities every day. This will help the children to plan their daily activities better. Day after day, theyˈll have good study habits. Parents should allow their kids to have a rest.   (32)   Kids shouldnˈt be allowed to watch TV while doing homework. If they have a chance to watch TV while studying, they may pay more attention to interesting TV programmes rather than textbooks. Books are studentsˈ best friends. But students hardly ever have a proper place for reading.   (33)   Make sure there is a clean desk and a comfortable chair in this room. If possible, a computer is a good choice. Knowledge comes from not only books but also the Internet.   (34)    (35)   Parents cannot help their kids do homework all the time. They can help kids to understand why they must do homework before the test. If kids can finish all the homework at home, theyˈll do better in the test at school! A．After the rest, they can study better. B．All of the students like doing homework. C．So parents should provide a room for kids. D．First of all, learn to plan their time properly. E．Teenagers have plenty of energy to deal with pressure. F．Finally, itˈs necessary for kids to finish homework on time. G．Kids should be allowed to surf the Internet to look up more useful information. 五、单词拼写-单句：本大题共10小题，共10分。 36.Zhang Guimei devoted(把······奉献给) her l           to helping girls from poor areas. 37.We want a s           room and a double room for the three of us. 38.My sister g           the old woman across the busy street safely. 39.Her strong d           to study every day helped her become the best in her class. 40.The volunteers f           the stray dogs every weekend and gave them warm shelters during the winter. 41.She became a s           writer by practicing daily and never giving up on her dreams. 42.His strong d           to win the competition made him train harder than anyone else on the team. 43.Good l           always ask questions in class and take notes to improve their understanding. 44.Even a            (单个的) small act of kindness can brighten someoneˈs day and spread positivity. 45.A            (一生) of learning keeps your mind active and helps you discover new passions every day. 六、首字母短文填空：本大题共10小题，共10分。 How can you become a good learner?
