Sometimes there doesn’t seem to be enough rain. Other times there is too much. Maybe thereisn’t a lot we can do to control the rain, but there is a lot we can do to reduce problems caused bydifferent rainfall patterns.
A new development at the London Wetland Centre in Barnes solves the problems of managingwater with a “Rain Garden”. We are likely to be hearing about it a lot more often over the next fewyears. The idea is that the garden owner can store rainwater and use it in dry periods. They canreduce the problems caused by extra rain this way.
One of the key problems that the rain garden tries to deal with is the problem caused by toomuch water in the street. In a natural environment, a lot of rainwater is sent back into the air byplants. Much is also absorbed deep into the ground, and flows into streams and rivers. What happensin city environments can be completely different —— a large amount of rainwater flows straight offthe hard surfaces of roofs and roads. The harder the rain, the less likely it will be absorbed into theground —— floods are the result. Rainwater running off roads is often polluted.
The rain garden deals with living plants rather than hard surfaces. Plants are designed to holdwater and release it slowly, either into the ground, to be absorbed by plant roots (and so eventuallyback up into the atmosphere) or to go down into the water table. Not only does the rain gardenreduce the amount of water that flows onto the street, but it helps to clean it because plants are very goodat breaking down pollutants(污染物).
What’s the main idea of the first paragraph?

A.Explaining why there is a lack of rain at times.
B.Introducing several different patterns of rainfall.
C.Telling us how to avoid problems caused by rain.
D.Giving the idea that there are ways to manage rain water.

According to the second paragraph, “Rain Gardens" are likely to _____.

A.harm the environment in the short run
B.become popular over the next few years
C.be turned down by most new developments
D.be too expensive for common people to accept

We can learn from the third paragraph that _____.

A.floods are often the results of small rains
B.a heavy rain is less difficult for plants to absorb
C.the rain garden helps send rainwater back into the air
D.larger amounts of rainwater flow straight off in city environments

According to the last paragraph, what does the rain garden help to clean?

A.The plants B.The ground. C.The water. D.The street.

Every morning, kids from a local high school are working hard. They are making and selling special coffee at a coffee cafe. They are also making a lot of money. These students can make up to twelve hundred dollars a day. They are selling their special coffee to airplane passengers. After the students get paid, the rest of the money goes to helping a local youth project.
These high school students use a space in the Oakland airport. It is usually very crowded. Many people who fly on the planes like to drink the special coffee. One customer thinks that the coffee costs a lot but it is good and worth it. Most customers are pleasant but some are unhappy. They do not like it if the coffee cafe is not open for business.
The students earn ﹩6.10 an hour plus tips. They also get school credit(学分) while they learn how to run a business. Many of the students enjoy the work although it took some time to learn how to do it. They have to learn how to steam milk, load the pots, and add flavor. It takes some skill and sometimes mistakes are made. The most common mistake is forgetting to add the coffee. But many students enjoy the job, because they learn a lot experience by serving people.

When Lucy and Maria Aylmer tell people they are twins, disbelief is the response. The 18-year-olds from Gloucester, U.K. are two of the five children born to their Caucasian (白种人的) father and "half-Jamaican" mother. While their other siblings (brothers and sisters) have a blend (混合) of features from their parents who have different skin colours, Lucy and Maria are unique: Lucy has fair skin and red hair, while Maria has brown skin and dark hair.
"No one ever believes we are twins because I am white and Maria is black," Lucy said. "Even when we dress alike, we still don't look like sisters, let alone twins. When we meet friends for the first time they all refuse to believe we are twins and some have even made us produce our birth certificates to prove that we are really twins."
Unlike identical (同卵的) twins, fraternal twins are bom from two separate eggs. The BBC reports that for a biracial (双人种的) couple expecting twins, there is about a 1 in 500 chance those twins will have different skin colors.
The Aylmers are proud of their uniqueness.
"Now we have grown older, even though we still look so different, the bond between us is much stronger," Lucy said. "Now we are proud of the fact that we are each other's twin sister. Maria loves telling people at college that she has a white twin sister — and I'm very proud of having a black twin sister, too."
Lucy and Maria are unique because _______.

A.they are fraternal twins
B.their siblings are all black
C.they are hybrids of multi-racial parents
D.they are twins with different skin colours

How do people usually react to the twins' physical appearances?

A.They think it possible.
B.They joke about them.
C.They find it unbelievable.
D.They regard them as lucky dogs.

What can we learn about Maria from the text?

A.She comes from Jamaica.
B.She was born of biracial parents.
C.She bears mainly features other father.
D.She shares a birth certificate with her twin sister.

If your job requires a lot of sitting, you could be putting your health at danger.
The American Journal of Epidemiology (流行病学) did a study in 2010 on the correlation (相互联系) between sitting and an individual's physical health. In the study, 53,440 working men and 69,776 working women were surveyed on their time spent sitting. The subjects were all disease free when employed. The researchers identified 11,307 deaths in men and 7,923 deaths in women during the 14-year follow-up.
The findings: Women who reported sitting for more than six hours per day had an approximately 40 higher all-cause death rate than those who reported less than three hours a day, and men had an approximately 20 higher death rate.
Well, now's a fine time to get this information. But why didn't they tell me this years ago? I would have planned on taking a more active job instead of the sedentary (坐着的) job of an editor.
So what can you do if you have to work for a living at a job that requires a lot of sitting? Here are some ideas:
Take frequent breaks. It is recommended that workers vary activities, change their position, and take short breaks every 20 minutes to rest muscles and increase blood circulation. Get a standing desk. Some studies have shown that working from an upright position may be better for health. The serious fitness people can even purchase a treadmill (跑步机) desk. It only goes about one mile per hour. Have a walking meeting. If your group is kind of small, going for a walk while discussing topics is a good alternative.
According to the text, the study in 2010 ______.

A.found men reporting shorter sitting time than women
B.surveyed more men than women on their daily sitting time
C.identified fewer deaths in men than in women during the 14-year follow-up
D.discovered correlation between sitting and physical health in men and in women

We can infer from the text that the author did not recommend ______.

A.using a standing desk B.resting one's muscles
C.quitting sedentary jobs D.taking a walk while discussing

What does the underlined word "subjects" in Paragraph 2 mean?

A.Things being discussed. B.People being studied.
