One of my favourite things to do is hiking in mountains. Because nobody likes the idea of getting lost, I always prepare before every trip. But what’s the best navigation tool, a Global Positioning System (GPS) or a good old map and compass? Five of my friends and I hiked through the mountains on a trail I marked. One team of three carried a GPS, and the other team used a map and compass.
It took the GPS team 3 hours and 11 minutes to get through the whole hike, however, it took the map and compass team only 2 hours and 49 minutes. The biggest problem the GPS team met was that they lost the satellite signal (衛(wèi)星信號) in some places. With no map or compass, they had to walk around until they were in a place where the signal was good. The map and compass team was able to spot (認出) different landmarks, compare them to their maps and then use the compass to point them in the right direction.
When I head out on my future hikes, I’m bringing a map, a compass and a GPS to show me the way.
小題1:The writer prepares before every trip because he doesn’t _________.
A．like the old map or compass
B．know how to use the GPS
C．want to get lost in mountains
D．want to get into the mountains alone
小題2:The two teams _________.
A．had the same navigation tool
B．went along the same trail
C．had the same problem
D．finished the whole hike at the same time
小題3:In the end, the writer found out _________.
A．the map and the compass were too old navigation tools to use any more
B．it wasn’t necessary to bring a map and a compass together with a GPS
C．the GPS had some bad points in hiking in mountains
D．he wouldn’t use a GPS any more

小題1:C
小題2:B
小題3:C

Qi Haoran, a Junior 1 student at High School Attached to Harbin Institute of Technology, was quite busy over the past winter vacation—and not just with homework. Qi, together with 10 other classmates made a volunteer group to call on people to join the Clean Your Plate Campaign (光盤行動).
The 11 students went to many restaurants and told people the importance of saving food.“Excuse me, do you know that 950 million people around the world still haven’t got enough to eat? Could you please not waste food?”They would say this kind of thing hundreds of times every day.
China in recent years has experienced serious problems with wasted food. CCTV reported in January that the food Chinese people waste every year is enough to feed 200 million people for a year. It’s a tradition that Chinese people offer lots of food when they invite others to dinner. Many even feel that they will lose face if their guests have eaten all their food.
Luckily the campaign has got the support of many. In a restaurant in Xinjiang, the owner gives the guests who have eaten up all that they ordered a sticker. People can enjoy a free meal when they have 10 stickers. More than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their guests to take leftovers(剩飯剩菜) home.
Wasting food is a serious problem around the world, not only in China. It’s said that 2 billion tons(噸) of food ends up as waste every year in our country. This is as much as half of all the food in the world. The UN Environment Program and the Food and Agriculture Organization held a“Think, Eat, Save” program on January 24 to help reduce food waste.
To reduce food waste is a big task, and it needs time. It’s important that everyone does their bit, just like Qi. Did you finish your meals today?
小題1:The Clean Your Plate Campaign calls on people to __________.
A．do volunteer workB．work part time in restaurants
C．stop wasting foodD．wash their plates after dinner
小題2:What did the restaurant in Xinjiang do to support the campaign?
A．The owner would have dinner with those who had eaten up their food.
B．It offered a free meal to the guests who had finished all their food ten times.
C．It gave stickers to the guests who ordered small dishes.
D．It encouraged customers to take leftovers home.
小題3:From the passage , we can know that __________.
A．wasting food is a serious problem in China
B．Chinese people waste the most food in January
C．200 million Chinese people invite others to dinner every day
D．Chinese people usually don’t offer enough food to their guests
小題4:You can probably read this passage _________.
A．in a science book B．in a newspaper
C．in a tourist guide D．in an advertisement

The tradition of birthday parties started a long time ago. There are some traditions that you can find almost anywhere, anytime, such as sending birthday cards, blowing out the candles(吹熄蠟燭) on a birthday cake and singing the ‘Happy Birthday’ song. Others are only found for certain ages and in certain countries.
In China, on a child’s second birthday, family members put many things on the floor around the child. According to Chinese tradition, the first thing that the child picks up tells you what job the child will choose later in life.
For Japanese children, the third, fifth and seventh birthdays are especially important. At this age, there is a special celebration(慶祝) Shichi-Go-San (seven, five, three in Japanese) when children go to the temple wearing a new kimono (和服). The priest (僧侶) gives them special sweets, and the parents usually organize a party for their friends in their home.
In Argentina, Mexico and several other Latin American countries, girls have a special birthday celebration when they reach the age of fifteen. After a special ceremony (儀式), the girls dance a waltz with their father and other boys.
Eighteen is the traditional ‘coming of age’— the age when (in many countries) you have the right to vote (選舉權(quán)), join the army （參軍）and (in Britain) drink alcohol （酒）or buy a house.
In many English-speaking countries, a twenty-first birthday cake often has a key on top, or the cake itself is sometimes in the shape of a key. The key means that the young person is now old enough to leave and enter the family home at any time they want to! 
小題1:Which of the following birthday traditions can you find almost anywhere, anytime?
A. Putting many things on the floor.
