    The festival started as a local West Indian event, but from a small procession (游行) through the streets of Notting Hill, it's a huge multi-cultural arts festival now. In fact, it is the largest street carnival (嘉年华会; 狂欢节) in Europe. Only the Rio Carnival in Brazil is bigger.

    At the heart of the festival is a spectacular (壮观的) parade (游行). The carnival route (路线) is three miles long and hundreds of groups move along it. There's music, decorated floats, elaborated costumes and dancing. There are also live stages where artists from all over the world perform, but there is a lot more to the festival than just music.

    Billions of locusts (蝗虫) are moving through farms and fields in the East African countries of Ethiopia, Kenya and Somalia.

    Locusts are grasshoppers. Normally grasshoppers don't travel in groups and so they do little harm. But when there are lots of them, their bodies and behavior change. That's when they become locusts. Locusts travel in huge groups, laying eggs along the way, which produce even more locusts. In a single day, a small swarm () of the insects can eat as much food as 35,000 people do.

    The locust swarms in Ethiopia and Somalia are the worst in 25 years. These locusts are desert locusts. They began swarming about six months ago. By moving with the winds, desert locusts can travel up to 90 miles a day or more.

    Locust swarms are more common when heavy rains follow a long dry period. The insects lay their eggs in the wet ground. This season, East Africa has had its heaviest rainy season in 40 years.

    When the insects swarm, one square kilometer of land can hold as many as 150 million locusts. There are 700 square kilometers of land covered by the insects in Kenya alone.

    The insects are a threat to lives in the region, where food is already in short supply. Already many farmers who keep animals are struggling because locusts have eaten out the plants the animals usually live on.

    In East Africa, farmers have been shooting into the air or making noises in the fields, but that doesn't work against so many insects. Experts say that spraying pesticides (杀虫剂) over large areas from airplanes is the only way to reduce the number of insects. The UN has released (释放) $10million to help deal with the locust problem. The UN says about $70 million is needed to truly control the locusts with pesticides.

    16. Which is TRUE about locusts?

    A. Normally they don't travel in groups.

    B. A small swarm of locusts eat a lot of food a day.

    C. They lay eggs in the wind.

    D. They do little harm to the plants.

    17. East Africa has got the locust problem because ________.

    A. the land is too dry to grow crops B. farmers pull out all the grass there

    C. poor people love to eat locusts as food D. it has too much rain after the dry season

    18. How many locusts are there in Kenya?

    A. About 150,000,000 B. About 700,000,000

    C. About 1, 850. 00,000 D. About 105,000,000,000

    19. According to the passage, a "threat" probably can ________.

    A. bring good luck to people B. make people live a happy life

    C. cause danger in the future D. help keep more animals

    20. We can infer from the last paragraph that ________.

    A. farmers are trying to scare the insects off

    B. spraying pesticides can't solve the locust problem

    C. the UN thinks the locust problem isn't serious

    D. East Africa has required no more help so far

    五、阅读表达

    阅读短文, 根据题目要求完成各小题。

    Electives (选修课) are always popular with students because they offer the chance to learn something exciting, and they're a welcome break from regular courses like maths and physics. Here are just a few of the exciting electives, lucky teenagers can take in some of China's middle schools.

    ●Self-defense skills

    A school from Chongqing

    The school offers a self - defense course - just for girls. Those who attend the lessons have the chance to study basic self- protection skills in a one - on – one practice. They learn how to get away when they need to and defend themselves against attacks. "I feel safer in myself now, "said Zhang Yi, 15, a girl student.

    ●Pottery

    A school from Tianjin

    Young artists at the school love to get their hands dirty creating beautiful pieces. Students learn how to design and make various clay projects. At the end, they have the skills to make their own clay bowls, cups, vases and pots.

    ●Horse riding

    A school from Beijing

    Equestrians (马术) can look pretty cool, can't they? Teenagers at this school can now choose a course in riding skills. They're taught to communicate with their horses and how to use reins. To ride a horse in the proper way, a student must hold the head forward and keep his back straight. Students come away from this elective not only knowing how to ride a horse gracefully but also physically fitter!

    ●Couplets (对联)

    A school from Nanjing

    How many of you can write a couplet? This old literary (文学的) form is slowly disappearing, but Chinese culture lovers at the school are trying to make it alive. For their elective, teenagers study old couplets and try to rhyme (押韵) their own lines. Many of this year's students can't wait for the Spring Festival, when they'll be able to show off their new skills.
