If you have your own Acme Rocket Launcher, you can create and send up rockets that show off your personality and creativity.

All you need is your Acme Rocket Launcher and a few simple household materials:

★a 500ml plastic cola bottle

★scissors

★colored markers

★poster board

★glue

What to do:

Step 1 Clean the cola bottle completely and allow it to dry.

Step 2 Use markers to draw three small triangles(三角形) and one large triangle on the poster board. Cut out the triangles.

Step 3 Roll(卷起) the large triangle so that two of its sides touch and it forms a rocket’s nose cone. Glue the sides of the cone so that it holds its shape.

Step 4 Glue the nose cone to the bottom of the bottle to make the top of the rocket.

Step 5 Glue the smaller triangles to the other end of the cola bottle, around its opening. The triangles will be the tail fins.

Follow the launching instructions included with your Acme Rocket Launcher and have a blast!

【推荐2】In order to know a foreign language thoroughly(完全地), four things are necessary. Firstly, we must be able to understand the language when we hear it. Secondly, we must be able to speak it correctly with confidence and without hesitation(犹豫). Thirdly, we must be able to compose(创作) sentences that are grammatically(语法地) correct. Fourthly, we must know how to put sentences into paragraphs, so as to write a good letter or composition.

There is no easy way to success in language learning. A good memory(记忆力) is of great help but it is not simply enough to memorize rules from a grammar book. It is not much use learning long lists of words and their meanings by heart. We must learn words not by themselves but in sentences. We must learn by using the language. “Learn through use.” is a good piece of advice for those who are studying a new language. Practice is very important. We must practice speaking and writing the language whenever we can.

【推荐1】Most people have a place to call home on Earth. What about in outer space? The International Space Station(ISS) became our first “home” in space in 2000. It welcomed its first crew that year, paving the way for 20 years of future research.

“You just have this impression that we’re all citizens of not a particular country, but of the planet,” former NASA astronaut Scott Kelly told National Geographic about working in ISS. “We’re all in this thing called humanity together.”

Over the past 20 years, the ISS has mainly been used as a science lab, hosting 241 people from 19 countries, according to NASA. They have gone on spacewalks, done research on how space affects the human body, and even grown plants in space.

The station’s development has also benefited people on Earth. For example, the station’s water purification(净化) technology has been used in poor areas to provide clean drinking water. The station also helps to warn us of natural disasters, such as earthquakes.

However, after being our home in space for over 7000 days, the station is starting to get old. It has leaked(泄露) air a few times. Scientists think that the station can keep working until 2024. After that, scientists will bring it down to Earth. It is believed that Earth’s atmosphere will burn up most of the station. Other debris(残骸) will fall into the Pacific Ocean.

In the future, space will be home to more stations like the ISS. NASA is building a space station that is smaller than the ISS near the moon. Also, China will have its own space station up and running in 2022.

【推荐3】TV is good. You want to watch it all day and all night. But too much TV is not a good thing. When children watch too much TV, they usually have many problems. They may go to bed late at night and sleep in class the next day. It is usually difficult for them to remember what teachers say in class, so they can’t do well in tests.

“Children learn best by reading, talking and playing with others. When they watch too much TV, they don’t have much time for those things,” a scientist says.

Watching too much TV is not good for children’s health. They sit for a long time when they watch TV. What’s more, they may eat a lot of food. This can make them fat.

Fighting on TV is also a big problem for children. Children always think the fighting looks cool, so they always practice a lot to look like those fighting men. Those people who watch a lot of fighting shows are more likely to fight.

At last, scientists say, “Watch TV for two hours a day at most! There are lots of other fun things to do.”

Do you sleep well at night? I know many people have trouble going to sleep. Sleeping problems are bad for our health. How can we improve our sleep quality?     1    

Have regular sleep habits

Go to bed early every night. Try not to break this habit on weekends when you have to stay up late.     2     If you get enough sleep, you will wake up on time.

    3    

Don’t play on the computer for half an hour before going to bed. Studies show that it is bad for the quality of your sleep. Read a book or listen to some light music to prepare your body for sleeping.

Have a nice bedroom

It’s necessary to keep your bedroom clean and tidy.     4    . Make sure that you have turned off all lights. Also make sure that temperature is suitable.

Exercise as often as possible

Exercise will help you to fall asleep more easily. You’d better do some sports during the day, such as running, playing basketball and so on. Walk out for about an hour and you will sleep better at night.     5     If you do so , you won’t fall asleep quickly.

Eat in a proper way

Eat less for dinner. A full stomach may make it much harder for you to sleep. Remember all above. It can not only help you get to sleep faster but also help you get better night sleeps.

【推荐2】Most people follow others blindly just under the effect(影响) of peer pressure(同辈压力) or because they feel it safe to follow a large number of people. Some rare cases it might be right to follow the crowd, but in most cases this o be a big mistake. Actually there are reasons why we shouldn’t follow the crowd blindly.

According to a study, people often follow the crowd when they aren’t sure about the direction they should take. This means a large number of people could be following others without understanding what’s right and what’s wrong! That makes more people follow and as a result most people move in a certain direction even if it isn’t right.

A man who wants to be successful always hopes for others’ guidance and usually follows the same path of most people, but the question this man never asks himself is: Are all of those people successful? Of course not! If you want to follow a crowd, then follow a successful one. However, in real life you’ll on find one successful person among hundreds of people, and that’s why following the crowd makes no sense at all.

Most people act emotionally without thinking wisely. If you always follow others because they’re greater than you in number, then sooner or later you’ll discover that you’re taking emotional decisions you might regret later.

However, should we never follow the crowd? No. I’m not trying to say you should never follow the crowd, but instead I’m just asking you to think wisely before you take a decision. If you find others are right, there is no problem in following them, but if you have doubts about the direction they’re moving in, don’t follow them blindly.

【推荐3】National Volunteer Week started in 1974 and is held every April.     1     It is also a perfect chance to encourage others to take their first step towards becoming a volunteer. Making the decision to take the first step can be the biggest problem, because they often wonder if they will be able to meet the expectations(期望) of the organization(组织) . Some people fear that they don’t know anyone else in the group. Some people worry they don’t have enough time to volunteer.

    4     “Volunteering makes you look at the world differently. You see how little things can change a person’s life for the better, which makes everyone a better person.” Mason, a volunteer said. “Little things can change a person’s life.”
