【题目】One day, Jack’s parents told him that his grandpa would retire (退休) after working for forty years. Jack said in surprise, “I’m only seven, so it means Grandpa has been … er… A really long time!”

His parents said, “Yes. That’s why we are going to have a surprise party for him.”

Jack loved his Grandpa and wanted to do something special for him. He remembered the business card his grandpa had given him two years before. He knew that his grandpa would no longer have the position (职位) on that card, so he decided to build a new one for his grandpa.

When the big day came, Jack was ready. But he didn’t want to put his gift together with others’. He carried it around with him the whole evening.

When all the other people left, he took his grandpa’s hand and brought him over to a chair and gave him the gift.

His grandpa smiled, “Well, it must be a beautiful gift. May I open it now?” “Sure!” Jack said excitedly.

As Grandpa opened the gift, tears (眼泪) came into his eyes. Jack gave him the greatest gift he had ever got! They were business cards with his new position: FULL-TIME GRANDPA! Jack said, “Now your full-time job is my grandpa!”

“Well, how much do I get paid?” his grandpa asked, smiling. “As many hugs (拥抱) as you want!” With these words, Jack gave Grandpa a hug. “Well, I guess that means I’m the richest man in the world!” said Grandpa.

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. __1___. It causes the evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms(生物) on the Earth.

Much of the energy that comes from the Sun never reaches the Earth’s surface.__ 2__. Of the energy that reaches the lower atmosphere,30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, _3___, is actually used by green plants to produce food.

Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. ___4__ in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.

When sunlight strikes an object, some of the energy is absorbed and some is reflected. _5__. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.

A.It is either reflected or absorbed by the gases in the upper atmosphere.

B.approximately 0.023%

C.These gases act like the glass of a greenhouse

D.greenhouse gases allow heat energy to escape from the Earth's surface

E.The amount reflected depends on the surface.

F.The Sun is the major source of energy for our planet

G. they reflect heat energy escaping from the earth back to the earth's surface.
