【題目】I don't know whether the books __________ to the homeless children next month are really useful.

A. given B. to be given

C. giving D. which were given

【答案】B

【解析】句意：我不知道將于下月送給無家可歸的孩子們的書是否真的有用。根據(jù)next month可知名詞the books后作定語的非謂語動詞在謂語動詞之后發(fā)生，故用動詞不定式，因為books和give有被動關系，故用動詞不定式一般式的被動式，所以B項正確。

【題目】 "When I was 16 years old, I was diving in Greece, but I was disappointed because I saw more plastic bags than fish.” These are the words of Boyan Slat, an engineer who designed the world's first ocean plastic cleanup system.

Every year, more than 8 million tons of plastics end up in our oceans, according to the UN Environment Programme. It is predicted that the weight of ocean plastics will match the weight of all the fish in our oceans by 2050. To prevent this from happening, in 2013 Slat created the Ocean Cleanup, an environmental nongovernmental organization, and put his plan for an ocean cleanup device into action.

After years of research and development in the Netherlands, a device called System 001/B successfully started gathering plastics on October 2, 2019. The device uses a 600-meter-long C-shaped tube to gather all the floating rubbish. Unlike other cleanup methods, the system floats freely according to the direction of the waves, which allows waste to flow into and stay within the device. A sea anchor is attached to either end. This slows down the system as it floats through the water and allows the faster-moving rubbish, carried by the waves, to flow into its mouth. System 001/B can also collect waste below the surface using a 3-meter-deep skirt（擋板）attached to the end. After being gathered, the trash will be dragged back to shore by boat and recycled.

Right now, the system operates in the Great Pacific Garbage Patch, an area that is 3 times the size of France. Once operational, the Ocean Cleanup expects a full fleet to be able to clear 50% of the Great Pacific Garbage Patch in 5 years.

"It remains to be seen whether this dream will become a reality, but it is undeniable that humanity must work together to reduce our plastic use and repair the damage our waste has caused," Slat said. "We are starting to see a young generation that gets it and is excited about a sustainable （可持續(xù)的）future, but the question still comes down to: Are we going fast enough, and how much damage will have been done before we get there?"

【1】The underlined word “match” in Paragraph 2 probably means “_________”.

A.compareB.equal

C.measureD.cover

【2】Why did Boyan Slat create the Ocean Cleanup?

A.To collect ocean plastic waste.

B.To help to invent System 001/B.

C.To protect the living environment of fish.

D.To do research on the ocean environment.

【3】What can we know about System 001/B?

A.It can collect and recycle garbage at the same time.

B.It can only gather ocean waste which floats on the water.

C.It aims to clear up the Great Pacific Garbage Patch in five years.

D.It is an ocean-cleaning device which has already been put to use.

【4】What does Slat want to tell us according to the last paragraph?

A.Young generations care less about the environment.

B.The future ecology of the oceans is deeply worrying.

C.People should work hard to decrease plastic pollution.

D.It's quite difficult to repair the damage to the environment.

【題目】閱讀理解
D
A buld-it-yourself solar still（蒸餾器） is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it's an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it's all but impossible to find natural substitutes. The only components required, though, are a 5' 5' sheet of clear or slightly milky plastic, six feet of plastic tube, and a container— perhaps just a drinking cup — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.
To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher's productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole.
Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet's center down with a rock. The plastic should now form a cone(圓錐體) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.
The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸發(fā)) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won't have to break down the still every time you need a drink.
（1）What do we know about the solar still equipment from the first paragraph?
A.It's delicate.
B.It's expensive.
C.It's complex.
D.It's portable
（2）What does the underlined phrase “the water catcher” in paragraph 2 refer to?
A.The tube
B.The still
C.The hole
D.The cup
（3）What's the last step of constructing a working solar still?
A.Dig a hole of a certain size
B.Put the cup in place
C.Weight the sheet's center down
D.Cover the hole with the plastic sheet
（4）When a solar still works, drops of water come into the cup form.
A.the plastic tube
B.outside the hole
C.the open air
D.beneath the sheet

To me, the concept of home changes continually along with my age.

In my childhood, home was a string of calls. It seemed that I am provided with less freedom than today’s children. I didn’t have to show up in front of my parents right after school. Instead of, I would go to play with my classmate who lived in the neighborhood. Days passed by as I grew up in a company of those calls. Even now the ringing voices are still echoed in my ears.

With I read more and more, my world has opened up, presenting a broader picture before me. The bed I used sleep in becomes too small, and words of care from my parents begin to sound endlessly. How I wish I could have a space of me own someday!

【題目】 Recently, a new study suggests that staying positive through the cold season could be the best defense(抵御) against getting sick.

In an experiment that exposed（暴露）healthy volunteers to a cold of flu virus, researchers found that people with a generally sunny emotion were less likely to fall ill. The findings, published in the journal “Psychosomatic Medicine”, build on evidence that a “positive emotional style” can help defend the common cold and other illnesses.

“People with a positive emotional style may have different immune responses to the virus,” explained Dr Sheldom Cohen of Carnegie Mellon University in Pittsburgh. And when they do get a cold, they may experience their illness as less serious.

Cohen and his colleagues had found in a previous study that happier people seemed less susceptible(易受影響的) to catching a cold, but some questions remained as to whether the emotional quality itself had the effect.

For the new study, the researchers had 193 healthy adults complete standard measures of personality qualities, physical health and “emotional style”.

Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy and tense had a negative style.

Afterwards, the researchers gave them nose drops containing either a cold virus or a particular flu virus that causes flu-like symptoms. Over the next six days the volunteers reported on any aches, pains, sneeze they had. Cohen and his colleagues found that positive emotions really have the big effect of fighting virus.

【1】The results of the experiments by researchers suggest that _______.

A.people in excellent spirits are less likely to fall ill.

B.the emotional quality itself has the greatest effect of fighting virus

C.people with a positive emotional style seemed more likely to get ill

D.positive emotional people and negative people response similarly to the virus

【2】Dr Sheldom Cohen made studies and reached his conclusion by _______.

A.comparing the experimental results of different groups

B.looking into the forms completed by the volunteers

C.collecting data among people with a cold

D.observing the volunteers’ symptoms

【3】According to the passage, what quality should we develop to fight virus?

A.Clever.B.Hard-working.

C.Optimistic.D.Friendly.

【4】We can conclude from the passage that _______.

A.positive life can lead to success in one’s career

B.physical health is more important than mental health

C.the happier we are, the less likely we will be to fall ill

D.the more we are together, the happier we will be
