When I was growing up, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never yelled at us for playing in his yard. I remember him as someone who was a lot nicer than most of the adults in our community.

When Dr. Gibbs wasn’t saving lives, he was planting trees. His house sat on ten acres, and his life’s goal was to make it a forest.

The good doctor had some interesting theories concerning plant care and growth. He never watered his new trees, which flew in the face of conventional wisdom. Once I asked why. He said that watering plants spoiled them so that each successive tree generation would grow weaker and weaker. So you have to make things rough for them and weed out(淘汰) the weaker trees early on. He talked about how watering trees made for shallow roots, and how trees that weren’t watered had to grow deep roots in search of moisture. I took him to mean that deep roots were to be treasured.

So he never watered his trees. He planted an oak and, instead of watering it every morning, he beat it with a rolled-up newspaper. Smack! Slap! Pow! I asked him why he did that, and he said it was to get the tree’s attention.

Dr. Gibbs passed away a couple of years after I left home. Every now and again, I walked by his house and looked at the trees that I’d watched him plant some twenty-five years ago. They’re extremely tall, big and robust since they have deep roots now. However, the trees in my garden trembled in a cold wind although I had watered them for several years.

It seems that adversity(逆境) and suffering benefit these trees in ways comfort and ease never could. I stood there deep in thought.

Every night before I go to bed, I check on my two sons. I stand over them and watch their little bodies, the rising and falling of life within. I often pray for them. Mostly I pray that their lives will be easy. But I think that it’s time to change my prayer(祷词) because now I know my children are going to encounter hardship.

According to Dr. Gibbs’ theories, trees will become weaker if they _________.

A. are lack of care　　　　　B. are watered      C. are weeded out　　　　　D. are beaten

According to Para.3 and Para.4, we can infer that Dr. Gibbs’ motto(座右铭) may be       .

A. “Seeing is believing”                                    B. “Put everything in proper use”

C. “Practice makes perfect”                               D. “No pain, no gain”

A. strong　　                      B. strange　　       C. deep　　                        D. old

Which of the following may be the author’s best prayer for his two sons now?

Thousands of villages in the developing world have no telephones. They have no money to build telephone systems. A new kind of technology may help change this situation. I t reduces the cost of building and using telephone systems.

Traditional systems use wires to carry electrical signals from one telephone to another. The wires often cost much more than telephones. The new system is based on radio communication. Each telephone sends and receives signals through the air, but not through the wires. This reduces the cost greatly. The radio telephone gets their power from the sun.

Each is connected to a solar equipment that changes the sun’s energy into electricity. A battery stores the electricity until someone needs to make or receive a call. The telephone turns off by itself if the level of power in the battery falls too low. This prevents damage to the system. Each radio telephone is connected to a computer microprocessor. It rewards how many calls are sent and received. It controls the power supply.

The technology needs more study, but its new use of radio equipment sun power and computers may help start telephone ringing in the other parts of the world.

68. The radio telephone gets their power from_____.

A. the sun 　　　B. electricity 　　　C. battery 　　　D. a special equipment

69. Each telephone is connected to_____.

A. a solar equipment 　　　　　　　B. a radio machine

C. a computer microprocessor 　　　D. Both A and C

70. From the passage we can infer that_____.

A. the new telephone system costs less than before

B. we can not use the radio as before

C. the new telephone system will take the place of the old one

D. it will be much easier to radio from now on

71. The main idea of the passage is_____.

A. a simple telephone system has been invented and costs less money

B. thousands of villages will use the new telephone system very soon

C. traditional telephone system will become useless

D. the new system will be too good to use

The human body is a living machine ,and, like all machines, it needs fuel to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?

The energy value of food is usually measured in calories. A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃.The number of calories people need per day is different, as the chart below shows. Also, the number of calories you use at any moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.

The energy in food is mainly in the form of three kinds of chemical materials—carbohydrate（糖类）,protein and fat. Carbohydrate provides 3.8 Cal/gm（calories per gram） of energy, protein 4.0 Cal/gm and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the second chart shows.

Chart Ⅰ

Chart Ⅱ

1.____ calories are required to raise the temperature of 5 kg of water from 35 ℃ to 90 ℃?

A.55　　　　　　　　 B.175　　　　　　 C.325　　　　　　 D.275

2.If you lack for calories to support your running activities you’d better take more ____.

A. milk　　　　　　 B. peanuts C. rice　　　　　　 D. milk and rice

3.We may learn from the charts that ____.

A. a child aged eight requires more than 3 times the amount of calories that a baby does

B. a boy aged sixteen requires nearly twice the amount of calories that a boy aged eight does

C. a mother with a baby to feed uses up more calories than a hard-working farmer each day

D. an old man needs less calories than an 8-year-old boy on account of his less movement

4.Which of the following statements agrees with the passage and the charts above?

A. You need more calories for swimming that for mountain climbing.

B. If you take an equal amount of Vitamin containing the calories you need, you don’t need to eat any food at all.

C. Different people need different amounts of energy depending on their age, sex and the activities they are in.

D.3 grams of milk provides 16.6 calories because carbohydrate provides 3.8 Cal/gm, protein 4.0 Cal/gm, and fat 8.8 Cal/gm.

“Any time! Any where! Decades ago there was no such thing” – “Communication”.

Then, September 7th 1987, the global system for mobile communication or GSM was born. And international agreements that laid out the standards, regulations and practices gave rise to a global mobile phone industry.

To be honest, the world’s first mobiles were not so attractive and the range of effectiveness wasn’t very good. But they became a must-have among those wealthy people who could afford that. However, by advantage of GSM which has many different elements to it, we can all enjoy the ability to go around the world in 217 countries, land in that country and know that a phone would work.

There are other cell phone systems using different technology in the world. The majority of the United States and parts of South America have been using something called CDMA which is very rare in Europe. In some Asian countries like China, GSM and CDMA both exist at the same time. But the GSM Association claims 85% of the global mobile phone market. They estimated there are now about 2.5 billion different users who make more than 7 trillion minutes of calls everyday, and that’s not all.

20 years later, the mobile phone is so much more than just a phone. You can use it to send text messages, take pictures, show video, even surf the internet.

“The phone itself is involved from just being a communication tool, to be a tool for round-the-clock connectivity, you can not live without it even in a minute.” Mobile consultant Nick Lane also points out with so many customized styles and features, your mobile phone will become a symbol of you.

Where will the global mobile phone industry be in another 20 years? Certainly, there will be more connections than better coverage. As for where else technology will take us, one can only imagine.
