On May 9, James Givens was sitting in the car when he heard what 【小题1】 (sound) like a knock. He turned around only 【小题2】 (find) a goose pecking at the car door, which was highly unusual seen. He knew that the birds 【小题3】 (normal) preferred to observe humans from a distance.

But on this day, the goose appeared to be determined to get his attention and did not stop pecking 【小题4】 Givens opened the car door and stepped out. Although 【小题5】 (force) to walk away a little out of fear, the bird kept turning around to make sure that he was following. When they finally stopped, Givens realized 【小题6】 the mother goose did so — she needed help to free her baby goose that had got 【小题7】 (trap) in some balloon string.

Worried that the mother goose would attack him if he got close 【小题8】 the baby, Civens called the local chapter of Society for the Prevention of Cruelty to Animals. Unfortunately, they were unable to help right away. Mainly 【小题9】 (take) into consideration that the baby goose would not survive the delay, Givens decided to take on the task himself.

The mother goose watched patiently as Givens saved the little bird. As soon as the little goose was free, it ran to its mom. Givens said this was the most 【小题10】 (forget) incident in his life!

The truth 【小题1】 trees are vital to our life is not a secret. They provide us with food, wood and most 【小题2】(importance), oxygen. Now there is one more thing we can add to this list — blocking out harmful bacteria from water.

The discovery 【小题3】(make) by a team consisting of scientists from the Massachusetts Institute of Technology (MIT) and high school students who were seeking a 【小题4】(nature) water filter (过滤器) — one that would help communities in developing countries that do not have access to modern water filter systems.

The 【小题5】(research), led by Professor Rohit Karnik, decided to turn to trees for help because they could allow liquid to flow through, while 【小题6】(block) out air bubbles.

They began by cutting 1.5-inch-wide sections of tree bark from the branches of a white pine tree. The people related then tested the wood’s filtering ability by pouring water containing red dye particles of different sizes through. 【小题7】 their amazement, they found that it was effective in trapping all the particles. 【小题8】(encourage), the team conducted 【小题9】 experiment, this time with water 【小题10】 contained bacteria. Sure enough, the sapwood held back 99% of the bacteria, allowing only 1% to flow through.

I rolled over and turned off my alarm clock. It was still dark outside, so I felt my way to the wall switch and turned 【小题1】the light. I got 【小题2】(dress) quickly because I knew both of my dogs would be eager【小题3】(get) outside for their morning walk. I reached over to take a coat. However, I failed to check the weather report for today, so I wasn't sure what kind of coat I should wear.

I pulled on my light jacket, and【小题4】(lead) my bigger dog, Fluffy, to walk first. I opened the door and stepped outside.【小题5】(instant) I knew I had made the wrong choice. The grass was covered with frost and I tried to keep 【小题6】(I) balance.

I trembled with cold. Then I looked up at 【小题7】sky and saw it was full of stars. It was so beautiful and 【小题8】(peace). Suddenly, I felt warmth inside and stopped trembling. In all of its sweet seasons it had never failed to touch my soul. It had heated my heart on the 【小题9】(cold) days and lighted my spirit on the darkest nights. I thanked God for the love【小题10】created the moon, the stars and me.

Our lives here are full of sweet seasons as well. Make each day of them a creation of your love.
