Airships can fly because they are lighter than air, like balloons (气球).

But they also have engines (发动机), so they can fly long ways. In the 1920s and 1930s, airships carried passengers (乘客). They could fly from Europe to the U. S. in two days. That was much faster than the same trip by ship. The biggest airships had restaurants and bedrooms and carried up to 100 passengers.

The airships of that time were kind of dangerous, and many of them broke down. In 1937, a famous airship called the Hindenburg fell down near New York, and thirty-six people died. After that, passenger airships stopped flying. Planes became the most important way of carrying things and passengers because they were faster and safer.

Now a number of companies around the world are making airships again. They are much safer than the airships of the 1920s and 1930s. They are not for passengers, and they only carry things.

There are four main good points of airships:

(1)They don’t need airports. They can land in places where planes can’t.

(2)They can carry much more things than helicopters (直升飞机) can.

(3)They use much less fuel than planes and helicopter, so they are better for the environment.

(4)They can stay in the air for a long time, so they are good for the scientific work.

Today most things still travel on planes, ships, trains and trucks. But in the future, a lot more things could travel by airship because it is cheaper and better for the environment. Maybe there will be airships for passengers again too.

文章大意:本文主要介绍了自我意识是什么,它的重要性以及如何培养自我意识。

【推荐2】What are you like? It can be difficult to answer. If you see yourself from the outside, but being self-aware(自知的) can help.

Self-awareness is an ability(能力) to see ourselves clearly, to understand who we are, how others see us and how we get into the world. For example, if you’re self-aware, you may know that you love playing some kind of sports because you’re good at it, or you love watching cartoons because they help you relax.

Being self-aware lets you make better decisions about friendship, schoolwork and even which films to watch. You learn to trust your feelings more. It’s important because it helps to have a happier and healthier life. But being self-aware doesn’t mean you are selfish and only thinking of yourself. By understanding your feelings, you can understand others’ feelings, too.

A good way to be self-aware is by asking questions. Ask “what”, but not “why”. For example, if you don’t know why you keep fighting with your parents, ask yourself what you disagree on, but not why you are fighting. Another way is to try out new things, like playing a new sport or listening to different music. Finding out what you like and dislike, and what you are good or poor at is a part of learning more about yourself.

1. The writer explains self-awareness by ________.
A.telling a storyB.giving some examples
C.using old sayingsD.asking some questions
2. What does the underlined word “selfish” mean in Chinese?
A.友善的B.刻薄的C.无私的D.自私的
3. Paragraph 4 mainly talks about ________.
A.how to become self-awareB.how to ask “what” questions
C.why self-awareness is importantD.why it’s necessary to try new things
4. What would be the best title for the text?
A.Get to know yourselfB.It’s never too late to learn

文章大意:本文介绍了性格测试——MBTI。

【推荐3】

MBTI is a personality (性格) test. Many people in China are interested in it now. “Am I an ‘I’ person or an ‘E’ person?”     1    

Many people find the test helpful. It groups people into 16 types. So they can make decisions more quickly. “I’m an ‘E’ person. I should go to the party and make more friends.” “    2     I’d like to work by myself. I could be a writer in the future.” They may think like this.

    3     Some people take the test for a second time and get different results. Some people find it hard to answer some questions. “I like watching TV by myself. But I also enjoy playing with my friends. Am I an ‘I’ or an ‘E’ ”?

Personalities can change with time, and they are not black-or-white. You may be introverted now but become extroverted when you get older.     4     Don’t label (标签) yourself!

When you take a personality test, you may think, “Oh, that’s me.” That’s because the descriptions (描述) are generic (通用的).     5     So, don’t take it too seriously.

A.I’m an ‘I’ person.
B.But there are also problems.
C.Or, you can be both an “I” and an “E”.
D.They take the test to find out the answer.
E.They can be used to describe many people.
