Humans may not have landed on Mars (火星) just yet, but that isn’t stopping a European company from devising a plan to send four people to the Red Planet within the next few years．This project, called Mars One, aims to send a small group of people to Mars in 2022 and eventually establish a permanent colony on the planet.

“Everything we need to go to Mars exists,” said Mars One co-founder Bas Lansdorp in March 2014．“We have the rockets to send people to Mars, the equipment to land on Mars, the robots to prepare the settlement for humans．For a one-way mission, all the technology exists.” Yet the four astronauts chosen for the trip will be stuck on Mars—forever．And despite Mars One’s thorough planning, there are a number of challenges that may prevent the mission from ever taking place．The biggest road block could be the mission's huge cost ($6 billion)．However, Lansdorp is confident that Mars One will be able to fund the project by selling the broadcast rights for the mission and subsequent experiences living on the planet.

Those broadcast rights will also play a part in helping to select the people who will be sent to Mars．Lansdorp said the company will hold a selection process similar to a reality show．Lansdorp is expecting at least 1 million applications from people around the world．In addition to the cost, several other potential problems could inhibit (阻止) the mission to Mars.

“It’s even more challenging to send people there with life support, with food, with air, with all the other things like books, entertainment, means of communication and of providing for their own resources for a long stay on Mars,” said Adam Baker, senior lecturer in space engineering at Kingston University in London．“The size of the rockets you’d need to do this would be absolutely colossal.”

1.According to Project Mars One, humans could send four people to Mars within the next ________years.

A． seven B． eight C． ten D． six

2.According to Bas Lansdorp, which of the following is NOT TRUE?

A． Robots are prepared for the settlement for humans.

B． He could not come up with the fund for Mars One.

C． We humans have the rockets to send people to Mars.

D． The equipment is ready for humans to land on Mars.

3.The word “colossal” in the last paragraph is closest in meaning to ___________.

A． very large

B． very small

C． medium

D． average

4.Which of the following is an appropriate title for this passage?

A． Ready for a Round Trip to Mars

B． Ready for a Short Visit to Mars

D． Ready for a Walk on Mars

Speaking from my past experience, it is very difficult to find good friends that you can trust but once you have found them, they are worth keeping forever! Therefore, I think friendship is the most important relationship that anybody could have.

The qualities I look for in a friend are a good sense of humor but sensitivity when it matters. Also that friend would have to be strong-minded and highly spirited. I think that these qualities are the key qualities to look for in a good friend.

Even the strongest friends can still have arguments, although usually about more serious topics, rather than the usual teenage childish arguments. Some matters can seriously affect a friendship. If one of your friends started experimenting with harmful and dangerous drugs, what would you do ? A good friend would try to help as much as possible, whereas a bad example of a friend would simply shrug(聳肩) and turn a blind eye.

Not only the bad things affect friendship ---- good activities do too. Such as bonding with one another, not just by going out on a night with them but by spending quality time with them and talking to each other, which indicates a good ability to communicate. This is a key aspect of a good friendship.

Good friends do not always have to be in the same age group as you. I have a good friend and she is 47 years old and I am 16.

Unfortunately, some people lose contact with their friends as they grow older, which is a sad way to lose a good friend.

I think friendship is one of the most important things in life because if you have no friends you will have no happiness.

1.According to the author, true friendship _______.

A. is easy to get

B. deepens with time

C. needs management

D. affects one’s happiness

2.Paragraph 3 is mainly about______.

A. why drugs are bad for teenagers

B. problems that will test friendship

C. ways that help avoid arguments

D. whether a friend is trustworthy

3.According to the author, which matters least in friendship?

A. Age. B. Sensitivity.

C. Sense of humor. D. Communication ability.

4.Which of the following saying can match the author’s view on friendship?

A. Old friends and old wines are best.

B. A friend without faults will never be found.

C. A life without a friend is a life without the sun.

D. a friend to everybody is a friend to nobody.

If tests can make students nervous, anxious and even scared, shouldn’t schools just get rid of them? 1. Teachers and schools give students tests for very important reasons:

2. Giving a test is a way for a teacher to see which students are learning the skills and knowledge they should be learning, and which ones are having trouble. Depending on how kids do on the test, the teacher will know if he or she must go back over some things, or if it’s okay to keep moving forward。

To see how well your school is teaching you. All parents want their kids to finally graduate with the ability to earn a living. 3. And one way to do this is to have them take test.

To assign (指定) grades. 4. Besides your homework, tests are one of the best ways for you to show the teacher that you’ve really learned what’s being taught, and for the teacher to figure out what grade you should get. Grades are also a way to show your parents how you’re doing in school.

To keep you motivated(有積極性的). Admit it: you work harder if you know someone is checking up on your work. For example, if your mom tells you to clean your room but you know she will never go in and check, then you might not do it, right? 5. Because you know that you’ll eventually have to take a test on the material and you might be more likely to give it that extra effort and make sure you know everything you’re supposed to know.

A. To see if you’re learning.

B. To see if you are totally prepared.

C. Students must work hard to get good grades.

D. Well, believe it or not, tests don’t just exist to trouble you.

E. Grades are important in most schools, and tests play a big role.

F. So schools have to prove they’re trying their best to educate students.

G. Well, tests help make sure that you don’t leave your homework behind.
