This article is for all of the teenagers out ...

This article is for all of the teenagers out there. Even though ____ you are years from being fully grown, society regularly expects you to adult. Yes, you are ____ in many ways: many of you drive and do so quite safely, and you handle schedules that would ____ many adults. But you probably cannot process caffeine (咖啡因) as constantly as your parents can because of your still-growing bodies and brains.

I understand it feels grown-up to be drinking a cup of Starbucks. But all of this caffeine may worsen your anxiety, affect tonight’s sleep and tomorrow’s school performance, ____ nutrient absorption and even cause real trouble when mixed with alcohol. The following four aspects may well ____ the theme of this article.

The power of caffeine

Caffeine is widely considered a drug that is socially acceptable, universally used, even cool, but it still causes ____ symptoms such as headaches, fatigue and a lack of attention when removed from coffee-addicts’ diets.

How much is healthy?

Caffeine is by no means a nutrient; you do not need it to be healthy. ____, it is a substance that can leave you lacking nutrients because it has been shown to reduce calcium (钙). Caffeine probably causes the body to release water. And the more caffeinated drinks you consume, the less likely you are to drink water. So experts say that adolescents should consume ____ amounts of caffeine a day (≤100 mg).

Caffeine’s ____

According to the Centers for Disease Control and Prevention, about 65 percent of middle and higher schoolers are ____ to insufficient sleep on school nights. Some of their sleep problems can be mainly attributed to (归因于) caffeine, which can remain in the body for seven hours after ____, thus causing teens’ worse performance the next day. It is widely assumed that adequate sleep ____ proper growth and brain development. During childhood and adolescence, the brain goes through a period called synaptic pruning (突触修剪) when unnecessary connections are promoted.

Caffeine labelling

Caffeine is not listed on the Nutrition Facts column on food labels because it is not a ____. It may be listed as an ingredient, but the amount is not required. Caffeine is now added to foods such as gum, candy and water, along with makeup and beauty products that ____ to reduce swelling (肿块).

Taste preferences and eating habits are often cultivated in childhood and adolescence, so teens, when you consume sweet, caffeinated drinks every time you feel sluggish (无精打采的), you are creating a pattern that may be hard to break as an adult. It is advisable to come up with other ____ ways to boost energy so that you can master adulting better than many adults.

Shopping is not as simple as you may think! There are all sorts of tricks each time we reach out for that particular brand（品牌）of product on the shelf.

Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged（包装）in greens, yellows or browns because we think of these as healthy colours. Ice cream packets（包装） are often blue and expensive goods, like chocolates, are gold or silver.

When some kind of pain-killer （止痛药） was brought out recently, researchers found that the colours turned the customers off because they made the product look weak and ineffective. Eventually, it came on the market in a dark blue and white package — blue because we think of it as safe, and white as calm.

The size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to.

It is believed that the better-known companies spend, on average, 70 percent of the total cost of the product itself on packaging!

The most successful producers know that it’s not enough to have a good product. The founder of Pears Soap, who for 25 year has used pretty little girls to promote（促销）their goods, came to the conclusion: “Any fool can make soap, but it takes a genius（天才） to sell it.”

1.. Which of the following may trick a shopper into buying a product according to the text?

A. The cost of its package                          B. The price of the product

C. The colour of its package                    D. The brand name of the product

2.. The underlined part “the colours turned the customers off” (in Para.3) means that the colours ________ .

A. attracted the customers strongly                 B. had weak effects on the customers

C. tricked the customers into shopping              D. caused the customers to lose interest

3.. Which of the following is the key to the success in product sales?

A. The way to promote goods.                    B. The team to produce a good product

C. The discovery of a genius.                   D. The brand name used by successful producers.

4.. Which of the following would be the best title for this text?

A. Choice of Good Products.                     B. Disadvantages of Products.

C. Effect of Packaging on Shopping.             D. Brand Name and Shopping Tricks.

Is There Life on Earth?

There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20,000 light years ago).

Because of excellent weather conditions and extremely strong signals, Venusian

scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”

“How do you know this?” the science reporter of the Venus Evening Star asked.

“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe the air and survive.”

“What does this mean as far as our flying saucer program is concerned?”

“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”

“Are there any other dangers that you discovered in your studies?”

“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We call this the Consolidated Edison Belt. We don’t know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”

“Over here you will notice what seems to be a river, but the satellite findings indicate it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”

“Sir, what are all those tiny black spots on the photographs?”

“We are not certain. They seem to be metal particles(粒子) that move along certain paths. They emit gases, make noise and keep crashing into each other. There are so many of these paths and so many metal particles that it is impossible to land a flying saucer without its being smashed by one”.

“What are those stalagmite(石笋) projections sticking up?”

“They are some of granite formations that give off light at night. Prof. Glom has named them skyscrapers since they seem to be scraping the skies. ”

“If all you say is true, won’t this set back the flying saucer program several years?”

“Yes, but we shall continue as soon as the Grubstart gives us the added funds.”

Prof. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?

“Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere.”

1.According to Prof. Zog, the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because ________.

A. they need it on their way to the planet of earth

B. the earth’s atmosphere is filled with deadly gases

C. oxygen is far from enough in the area of Manhattan

D. there is no air on the planet of Earth

2.The “dark black cloud” in the 10th paragraph indicates ________.

A. the polluted air hovering over the surface of Earth

B. the mass of tiny drops of water floating above Earth

C. the mass of small things moving through the air

D. the dark clouds gathering before a storm breaks

3.The author wishes to call our attention to the fact that ________.

A. modern man has polluted his environment to such an extent that he may destroy himself if he carries on like this

B. there is no point in spending billions and billions of zilches to land a flying saucer on Earth

C. pollution has become so serious a problem on Earth that even Venusians find life there unbearable

D. it is difficult, if not altogether impossible, to land a manned flying saucer on Earth

4.The tone of this essay is ________.

A. hopeless and objective

B. serious and critical (批评的)

C. humorous and satirical (讽刺的)

D. sensitive and subjective

Wow，ladies! That is all I can say, I write this article with mixed emotions. Having Aiko the　 female　 robot　 around　 the house to help out could be either a blessing or a nightmare. If you are a working mother like me, then the idea of having a helping hand around would be a good thing. We working mothers dream about going home to find dinner on the table, a clean house and everything ready for the next day，that would be the perfect world.

Yet as always we women worry about being replaced，me included. Aiko has been created with special sensors (感应器) underneath her immediate“skin”cover. I believe her creator, Le Trung，has other motives(动机). Of course, he says it's not true. She doesn't complain, argue or talk back. She can carry on a conversation and help you with your math homework. She can tell you the weather outside and can speak in English and Japanese. She doesn't require any sleep nor does she complain about a headache or being tired. She can serve tea and give back massages. I'm sure some men out there would view her as the perfect woman or even“superwoman”. So with good reason I say having Aiko around could prove to be bad. As a woman and a wife，I worry about being replaced or even being compared to Aiko. How can you compete with someone or something so perfect like that?

Scientists have been trying to invent robots for a long time. There are many movies and books out there about robots. It looks like those crazy scientists are closer than we thought. Ladies, I think we are fighting a losing battle. So instead of trying to fight it，I guess we have no choice but to join　 them.　 Now　 where　 is　 my　 male robot? Hmm...I want him to look exactly like my Ken Barbie doll. Okay?

1.Le Trung created Aiko mainly to ________.

A. keep people company

B. teach people foreign languages

C. help children with their homework

D. help working mothers do housework

2.What can we learn about Aiko from the second paragraph?

A. She is poorly designed.

B. She is perfectly made.

C. She works better than expectations.

D. She is especially made for housewives.

3.Why does the author think having Aiko around could prove to be bad?

A. The robot could replace her.

B. The robot can do more than she does.

C. The robot makes a mess in the house.

D. The robot can speak human language.

4.What could be the author's purpose in writing the text?

A. To introduce a robot.

B. To argue against robot­making.

C. To show her fights with robots.

D. To describe the daily life of a working mother.
