Everybody is afraid of something. That’s what more than 1,700 kids told us when we asked them about scary(吓人的) things.

Last week, we gave kids a list of 14 scary things and asked which one they were the most afraid of. Here are the top 5 answers: terrible weather; scary movies; scary dreams; fights; the dark.

Not everyone is afraid of the same thing. And what makes one person scared can be no big deal for someone else. A lot of kids said their biggest fear wasn’t on our list.

Rachel, 11, was one of them. She’s most afraid of giant jellyfish(巨型水母) in Australia. “I am afraid of them because they’re bigger than people and they can kill someone in 3 seconds,” Rachel said.

Several kids said funerals(葬礼) scared them. Fireworks frightened(使惊吓) other kids. Even going alone to a big bathroom—like the kind in school or at the mall—can be scary, according to a few kids.

“Health problems can be scary,” some kids said. They said they were scared of throwing up(呕吐), wetting the bed, or getting fat.

Everyone will feel scared. That’s a good thing because fear is there to protect us. We’re born with a sense of fear so we can be careful of something dangerous. The best way to get over fear is to get more information about it.

1. Children may be most afraid of _______.
A.stormy daysB.dark rooms
C.scary moviesD.scary dreams
2. It is a good thing to feel scared because _______.
A.we’re born with a sense of fear
B.we can be careful of something dangerous

3. What does the writer mainly tell us?
A.Kids are always afraid of health problems.

文章大意:本文是一篇说明文。本文主要讲了用小苏打和醋发生化学反应产生的气体吹起气球的试验方法。
【推荐1】

Chemical reactions make for some great experiments. You can use the CO2 from a baking soda and vinegar reaction to blow up your balloon!

What you’ll need

★Balloon

★About 40 ml of water

★Soft drink bottle

★Vinegar

★Some baking soda

How to do it

★Before you begin, make sure that you pull the balloon long to make it easy to blow up.

★Put the 40 ml of water into the soft drink bottle.

★Add the baking soda and mix it with water.

★Put the vinegar in and quickly put the balloon over the mouth of the bottle.

What’s happening?

If all goes well, your balloon should inflate! Adding the vinegar to the baking soda lets CO2 come out. However, it doesn’t go out of the balloon, pushing it outwards and blowing it up.

文章大意:本文主要介绍了太空里有很多垃圾,有一些来自火箭,还介绍了有位美国宇航员在太空丢了只手套的状况,手套在太空以每小时两万八千千米的速度行驶,如果碰撞到其他的物体是非常危险的。

【推荐2】There is lots of junk (垃圾) in space. Some of it is from rockets. In 1996, a rocket broke into about 300,000 small pieces. So far scientists have found many man-made pieces flying around in space. Only a few of them are satellites and space probes (探测器). Astronauts also lose small things while working in space. In 1965, during the first American spacewalk, astronaut Edward H. White lost a glove. For a month, the glove stayed in space, travelling at a speed of 28,000 kilometres per hour. It became the most dangerous piece of clothing for the earth in history.

Things move very fast in space. If they hit one another it can be dangerous. A little piece of paint from a satellite once made a hole in a spacecraft window. Once American spacecraft dropped some bolts (螺栓), and scientists on the earth worried a lot. Luckily the bolts floated (漂浮) away into space. They could not hit the spacecraft.

1. Some junk in space is from ________.
A.spaceB.rocketsC.scientistsD.the earth
2. American astronaut Edward H. White once lost ________ in space in 1965.
A.a rocketB.some boltsC.a little piece of paintD.a glove
3. The glove in space may travel at a speed of ________ kilometres per hour.
A.300,000B.28,000C.10,000D.21,000
4. If the junk in space hits one another, it can be ________.

【推荐3】It’s hard to turn down a tasty banana. They taste good and you don’t have to wash them before eating them. However, British scientists say that the fruit may disappear by 2050.

One reason for this is climate (气候) change. Scientists at the University of Exeter collected data (数据) from 27 countries that produce 86 percent of the world’s bananas. They found that climate change has improved growing conditions in 21 of these countries. In the past 60 years, the average yield (平均产量) has reached 1.37 tons of bananas per hectare (公顷).

However, if temperatures keep rising, this advantage will disappear. Ten of the countries, including India, the world’s biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out.

Shouldn’t bananas grow more easily if it’s hotter outside? In fact, the perfect temperature range (范围) for growing bananas is between 24℃ and 32℃. If temperatures get too high, they will stop growing.

Diseases are another danger to bananas. Unlike other plants, the bananas we grow come from shoot cuttings (茎段) rather than seeds (种子). This means that all banana plants have the same genotype (基因型). In other words, if a disease is able to kill one plant, it could kill them all.

One serious disease is called Panama. Caused by fungus (真菌) in the soil, it spreads easily. It has spread across South Asia, Africa, the Middle East, and Australia. If one banana plantation suffers from the disease, it will take 30 years until it is able to grow bananas again. Scientists have yet to find a cure for this disease.


根据短文内容,选择最佳答案。
1. What does the underlined word “this” in Paragraph 2 refer to (指)?
A.A banana tastes great.
B.A banana will die out in 30 years.
C.A banana is convenient to be eaten.
2. From the passage, we can learn that __________.
A.in the last few years, the average yield of bananas has increased
B.panama has killed all the bananas in some areas like South Asia
C.the higher the temperature is, the better bananas will grow
3. What does the passage mainly talk about?
A.The difficulties of growing bananas.
B.The perfect conditions of growing bananas.
C.The reasons for the disappearance of bananas.
4. How is the passage organized?
A.B.C.
