【題目】________the rapid progress in high technology, 5G can help doctors treat patients ________are hundreds of kilometers away. It’s reallyamazing.

A.With; whoB.Under; thatC.In; which

【答案】A

【解析】

句意：隨著高科技的快速發(fā)展，5G可以幫助醫(yī)生治療幾百公里以外的病人。真的很神奇。

考查定語從句和介詞辨析。with隨著，表伴隨；under在……下面，表地點(diǎn)；in在，表地點(diǎn)或時(shí)間。who用于先行詞是人時(shí)，which用于先行詞是物時(shí)；that可指人指物，無實(shí)義。本句是“with +名詞+介詞短語”復(fù)合賓語結(jié)構(gòu)，根據(jù)“the rapid progress in high technology高科技的快速發(fā)展”，可知用with。patients（病人）是人，關(guān)系詞需用who，故選A。

【題目】 An elderly carpenter (木匠) was ready to retire (退休).He told his boss of his plans to leave the house business and live a more comfortable life with his wife enjoying his big family, looking after their grandchildren. He would miss the paycheck (薪金), but he really needed to retire. The boss was sorry to see his good worker go and asked if he could build just one more house as a personal favor. The carpenter agreed, but this time it was easy to see that his heart was not in his work. He used bad materials and worked carelessly. It was an unlucky way to end his career. When the man finished his work and the boss came to check the house, he handed the front door key to the carpenter. "This is your house," he said. "My gift to you." What a shame! If he had only known he was building his own house, he would have done it all so differently. Now he has to live in the home he had built sadly.

So it is with us. We build our lives in an absent-minded way, willing to do less than the best. At important points we do not give the job our best effort. Then with a shame, we fall into the situation we have created and find we are now living in the "house" we have built.

【1】The elderly carpenter planned to live a more comfortable life alone.

【2】The boss asked the man to build just one more house as a personal favor.

【3】The man agreed with the boss, he used the good materials and worked carefully.

【4】After checking the house, the boss didn't give it to the man as a gift.

【5】From the story, we learn your life today is the result of your attitudes and choices in the past.

【題目】 Can we give a hand to those endangered animals? Yes, we may only do a little bit, but together our small actions add up to a lot.

1 Protect wildlife habitat (棲息地).

Perhaps the greatest threat that faces many species (物種) is the widespread destruction (破壞) of habitat. Cutting down forests, farming, and development all result in loss of wildlife habitat. In areas where rare (稀有的) species live, habitat destruction can quickly force a species to extinction (滅絕). By protecting habitat, entire communities of animals can be protected together naturally.

2Reduce the threat (威脅) of invasive (入侵的) species.

The spread of non-native species has greatly reduced native populations around the world. Invasive species compete with native species for resources (資源) and habitat. They can even prey (捕食) on native species directly, forcing native species towards extinction.

3 Place decals (貼花紙) on windows.

It is reported that as many as one billion birds in the United States die each year because of collisions (碰撞) with windows. You can help reduce the number of collisions simply by placing decals on the windows in your home and office.

4 Slow down when driving.

Many native animals have to live in developed areas and this means they must move in human-living areas. One of the biggest obstacles (障礙) to them is that created by roads. Roads divide habitat and present a constant (不斷的) risk to any animal attempting to cross from one side to the other. So when you’re out and about, slow down and keep an eye out for wildlife.

【1】Is the greatest threat that endangered animals faces created by roads?

__________________________________________________________________________

【2】How many ways to protect the endangered animals is mentioned in the passage?

__________________________________________________________________________

【3】Why are people advised to put decals on windows?

____________________________________________________________________________________________________________________________________________________

【4】Do you think it necessary for people to protect the endangered animals? Why or why not? ____________________________________________________________________________________________________________________________________________________
