Everyone has done experiments in high school laboratories，but have you ever thought about designing a satellite to explore space？

On Nov．19，a team of students from Thomas Jefferson High School for Science and Technology in the US awed peers and even scientists by successfully launching a satellite．

The first satellite designed and built by high school students was sent up into space along with a record setting．28 other small ones on a rocket were sent from a NASA center in Virginia，CNN reported．It took the students seven years to build．

The students call their tiny satellite TJ3Sat，which is named after their school．It is just 10x10x12 centimeters and weighs only 0．89 kilograms，according to Orbital Sciences，a company which developed the rocket and supported the students’ project．It can be controlled with a smartphone．

Like most satellites，TJ3Sat can send and receive data．The small spacecraft is equipped with a voice synthesizer (合成器)，which can switch text to voice and transmit those sounds back to Earth over radio waves，said Orbital officials．In this case，anyone can give it a try via the project’s website (school website) by submitting (提交) a text．The texts that get approved will be sent to the satellite，changed to voice and then broadcast back to Earth via radio waves．

“I can say ‘Go Colonials’on our ground station and when it is on the other side of the world，in India，someone can hear‘Go Colonials’over the radio，”the team explains on the website．

The satellite will stay in space for at least three months．

School principal Evan Glazer told The Washington Post that the project started in 2006 as an activity in the spare time．Later it became a research project for a select group of seniors．

At a time when American students are busy with SATs，the launch of the satellite shows what diligent teenagers can achieve when allowed to pursue their own curiosities，Glazer said．

“It used to be that kids growing up wanted to be an astronaut,” Andrew Petro，program executive (主管) for small spacecraft technology at NASA，said in a statement．“I think we might be seeing kids saying what they want to do is build a spacecraft．The idea here is that they really can do that．”

1.The underlined word “awed” in the second paragraph is closest in meaning to _____．

A．influenced

B．a(chǎn)mazed

C．delighted

D．inspired

2.Which of the following statements about TJ3Sat is TRUE according to the article？

A．It took a group of students about a decade to build the satellite．

B．Besides TJ3Sat，28 other small satellites were built by the students．

C．TJ3Sat can receive text messages that the students send into space，which can be changed to voice messages and broadcast back to Earth．

D．TJ3Sat is expected to stay in orbit for the next year，sending out messages together with information about its position in space．

3.According to the article，the launch of the satellite _______．

A．is evidence of the advance of spacecraft technology

B．proves that hard working teenagers can achieve a lot

C．shows the importance of extracurricular activities at school

D．has inspired many people to take an interest in space travel

Culture and Cuisine

The United States is known for jazz and blue jeans．But travel to Paris and ask your average French citizen about American cuisine (烹飪) and he’s likely to answer，“ McDonalds．” Ask the same thing of any American citizen on any American street and I’m afraid you’d get the same answer，or something close to it．

Hamburgers and hotdogs and fries are all fine，but with American malls and other outlets standardizing everything from clothing to food，the sad truth is that American cuisine is becoming more homogeneous―all the same―no matter where you live．True，many Americans are eating more varied foods these days，but these are largely the cuisines of immigrant groups，and they are quite likely to be affected by homogenization of American cuisine．

So what exactly is American cuisine？ Well，to some extent it is a reflection of our melting pot culture，meaning that Europeans made huge contributions in the form of wheat，dairy products，pork，beef and poultry．But American cuisine also includes products that once were known only to the New World，including potatoes，corn，pumpkin，sweet potatoes，and peanuts．

The one region of the country where you still find all these things in daily use is the Deep South．The South lost the Civil War，but children of the southerners are winning the battle to preserve and advance their cooking traditions—and in this case one of the few cuisines can truly be called American，which is why we’re pleased to have Low Country cuisine in this issue of food creation．That’s right，grits and gravy are back in a big way in cities like Charleston and Savannah．Truth is，they never really left，but up until a decade ago Low Country cuisine was more common at home than in restaurants．

In fact，a large number of tourists now go to the lower Atlantic region in order to experience this extraordinary cuisine for themselves．Time will tell whether Low Country cuisine becomes popular in other regions of the country in the way that，say，Italian cuisine has，but it’s amazing and heartening to see one of our true cultural treasures enjoying renewed popularity in these increasingly homogeneous times．

1.According to the passage，American cuisine impresses people as being _______．

A．dull and changeless

B．rich and various

C．popular and delicious

D．disagreeable and unpleasant

2.It can be seen that the writer feels regretful that _______．

A．cuisines of other countries play a more important role in America

B．American cuisine has become increasingly lacking in variety

C．American cuisine tends to vary because of immigration

D．American cuisine is being changed by foreign cuisines

3.From the passage，we know that grits and gravy _______．

A．were cooked with new materials after the Civil War

B．a(chǎn)re gaining popularity in the south of America

C．were more popular over ten years ago

D．a(chǎn)re seldom served in restaurants

4.What’s the writer’s attitude towards the renewal of Low Country cuisine in America？

A．Concerned and cautious．

B．Hopeless and doubtful．

C．Positive and supportive．

D．Critical and disapproving．

閱讀下面短文，然后按要求寫一篇150詞左右的英語短文。

“When should I begin to acquire good habits?”a young boy asked his teacher.

“How old are you?” asked the teacher.

“Eight years old, sir.”answered the boy.

“Then you have just lost eight years,”the teacher replied.

There is no doubt that habits are formed at a very early age．When one is young, it is easy to acquire good habits.

Good habits are practices that help us in our daily life．The habit of brushing one’s teeth in the morning, for instance, keeps one’s teeth clean and prevents a bad smell which is unpleasant to others．Bad habits such as sticking one’s tongue out, biting one’s fingernails and picking one’s nose, are undesirable ways of behaving in front of others．If we want people to enjoy being with us, we should try to develop habits that are pleasant.

It is said, “We sow an act; we reap a habit．We sow a habit and we reap a character.” The habits we formed at an early age shape our character．Habits are like tributaries(支流) which flow into a river．The river is made up of all its tributaries; a person’s character is made up of all the habits that he or she has acquired over the years.

Barack Obama has really gone wild. The US president has taken part in the survival television show Running Wild With Bear Grylls, which will air on NBC later this year. In the show, Obama goes on an adventure with host Bear Grylls, learning how to survive in the Alaskan wilderness.

Edward Michael “Bear” Grylls, 41, has become known around the world as one of the most famous outdoor adventurers. The Briton has appeared on a number of wilderness survival shows in which he has climbed, sailed, and eaten bugs or cow tongue.

Obama doesn’t have to eat bugs or cow tongue on his adventure with Grylls. But he does have to eat leftovers - a bloody salmon (三文魚). It was partly enjoyed by a bear that left some meat behind.

Although he is far from the White House kitchen, Obama seems to enjoy the outdoors. “As president, I am in what’s called the bubble（保護(hù)膜）, and the Secret Service makes sure that I’m always out of danger ... but I sometimes want to get out,” he said in a video.

However, Obama’s appearance on the show isn’t just for fun. He took part to raise awareness of the effect global warming has had on the US’s largest state, Alaska.

C. takes in some unusual food

D. never has any difficulty

2.It can be inferred from the passage that _____.

A. Obama has been tired of the life in the White House

B. US presidents have never been in danger because of the Secret Service

C. the food prepared in the White House is not as good as the food outdoors

D. The life outside the White House is sometimes attractive to the president

3.The purpose of Obama’s appearance on the show is _____.

A. to have some fun

B. to promote environmental protection

C. to enjoy the wilderness in Alaska

D. to get out of the White House for a change
