閱讀下列短文,從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中,選出最佳選項(xiàng)。

Energy goes from one plant or animal to another.A food chain shows how this energy moves.Each time an animal gets eaten,its energy is passed onto the animal that eats it.The food chain is very important because it keeps the balance of nature.If one part of the food chain disappears,it can affect all the other plants and animals.Any threat to the food chain is a threat to the environment’s biodiversity(生物多樣性).The food chain helps keep animal populations in balance.However,if something happens to damage one of the links in the food chain,that balance is broken.If one animal becomes endangered,it puts all the animals above it at risk.

Some of the threats are natural,such as wildfires,hurricanes,tornados,floods and so on.But the biggest threats to the food chain come from you and me.These threats include overfishing,logging,farming,development,pollution,etc.The food chain is endangered anywhere humans have had an effect on the natural environment.

A recent study shows that the overfishing of large sharks is damaging the food chain along the US Atlantic coast.Canadian and American scientists say sharks are being killed in great numbers for their meat and fins(鰭).Now,not enough sharks are around to eat the cownose ray.The ray’s population has increased and they have eaten up the shellfish to the point where it has hurt commercial(商業(yè)的) fishing.

Many of us disturb the natural environment in our own backyards.It’s up to us to take care of the environment and try not to disrupt the natural food chain.If we don’t act responsibly,animals will start disappearing.

1.What can we learn from Paragraph 1?

A.The food chain is not easy to be broken.

B.The energy of an animal usually disappears when it dies.

C.Increasing the links will not break the balance of nature.

D.Breaking the food chain is bad for the biodiversity of the environment.

2.The study mentioned in Paragraph 3 proves that .

A.human activities can be a big threat to the food chain

B.we are all responsible for the breaking of the food chain

C.natural disasters are hard to break the food chain

D.hunting large sharks for meat is beneficial

3.We can infer that the writer wrote this passage mainly to .

A.explain what the food chain is

B.tell us something interesting about nature

C.suggest that we stop eating meat to save animals

D.suggest that we should not disrupt the natural food chain

Last Thursday, Michael and Linda stood behind large food trucks distributing meals to 4,000 homeless people for their wedding reception on the border town of Kilis. The couple had decided that instead of hosting their friends and family for a traditional feast reception, they would feed the victims from an earthquake-stricken area.

The idea came from the bridegroom's father, Ted, who volunteers for a Turkish relief organization. For the past few years, the organization has distributed daily meals to thousands of people who've suffered from natural disasters. He approached a representative of the organization and suggested that the family cover part of the costs of feeding them for the day.

Then he told his son, who was surprised by the suggestion, but soon won over. When he told that to the bride, she was really shocked but finally accepted because in southeastern Turkey there is a real culture of sharing with people in need. They love to share their food, their table and everything they have. And afterwards she was quite amazed about it. So, they arrived at the distribution center on Thursday to spend the day serving food and taking photographs with their grateful recipients (接受者)．

On Tuesday evening, the newly married couple were still pleased with their decision to quit a personal celebration for one with a greater good. “It's like sharing a dinner with your friends and family who have this kind of thing on a daily basis or sharing something with people who don't even have the most basic things,” Michael said. “Hopefully, this will also give the start for other wedding dinners to be held here with our brothers and sisters in need.”

1.Why did so many people crowd in Kilis?

A. To attend Michael and Linda's wedding.

B. To escape the damaging earthquake.

C. To support the organization.

D. To help distribute free daily meals.

2.How did the couple celebrate their wedding?

A. They treated their friends and relatives to a big dinner.

B. They afforded the entire cost of the day for feeding victims.

C. They shared their happiness with the homeless in Kilis.

D. They took photos with the grateful victims.

3.What does the underlined word “approached” in Paragraph 2 mean?

A. consulted with B. moved towards

C. came across D. took in

4.We can know from the text that __________________.

A. Michael doubted if more new couples would follow him

B. Ted was a representative of the organization

C. Linda adopted the suggestion immediately she heard it

D. Kilis is a place which lies in southeastern Turkey

When you’ve seen a couple fighting or having a pity argument,what is the first thing that comes into your mind?Probably you think that you will never allow arguments to set in your relationship,especially when you get married,or will never think to start one,but arguments seem to come naturally.

You argue about the brand of coffee,or what to eat at lunch,who will do the dishes,etc.Sometimes,more than that,but regardless of your reasons for the argument(or fight),fixing a troubled relationship and having a solution is very important.

Our partners are our most valuable fortunes.Companions provide a listening ear for our troubles,support for our dreams,and a safety net when we fall.They give us love,even when we are unlovable.They are and must be our friends.

Inevitably,though,sometimes we go through troubled periods and a solution should be sought through the following steps:

Address the situation.Admit to your partner that something is wrong and needs to be fixed.

Determine the problem.Together,discuss what problems we are facing.Be honest and let your honesty be in its proper place.Remember,you are talking to your partner,another half of yourself.

Apologize.We accept responsibility for our actions and seek forgiveness.

Refuse to blame.In addition,we must avoid defending ourselves.There could be a temptation to argue over who did what;however,the goal is not proving who is right but saving the relationship.

Begin repairs.Ask,“What can I do to rebuild our relationship?” The key here is to do willingly whatever is requested.

Commit to rebuilding.Immediately start investing your time,energy,and love in restoring the relationship.In order to have a good relationship with a partner who accepts and loves us,we must be willing to pay the high price of patching up the broken relationship.Walking away might seem easier,but in the long run,we would lose a valuable treasure.

Have you ever heard a news reporter talk about DNA?Reporters talk about DNA found at the scene of a crime.They talk about police finding DNA “fingerprints”.Police sometimes use DNA as a clue to find out who committed the crime.

DNA is a substance(物質(zhì))that makes up genes.Everything alive has genes.Plants have genes.Animals have genes.You have genes.

Genes are the basic units of heredity(遺傳).Heredity means all the characteristics you inherit from your parents.You get your genes from your parents.You inherit half of your genes from your mother.You inherit half of your genes from your father.

Genes are a kind of code.A tree’s genes tell what shape its leaves will be.A cat’s genes tell what color its fur will be.Your genes tell what color your eyes will be.Your genes tell what color your hair will be.Everything about you comes from the code in your genes.

Genes line up on strands(鏈)called chromosomes(染色體)in cells.Everything alive is made up of cells.Chromosomes are in the center,or nucleus of cells.

Different parts of you are made of different kinds of cells.Your muscles are made of muscle cells.Your skin is made of skin cells.The code in your genes tells your body to make different kinds of cells.The genes in each cell tell the cell how to work.They tell the cell when to make new copies of itself.

An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants.He experimented with pea plants in the 1860s.One of the things,or traits(特質(zhì)) Mendel studied was what makes some pea plants tall and some short.He said that the traits must come from units of heredity passed from the parent plants.These units were later called genes.

In the mid-1900s,scientists discovered that genes are made of DNA.In the 1970s,scientists learned how to change DNA with genetic engineering.Scientists also learned that problems with certain genes cause diseases.Muscular dystrophy,cystic fibrosis,and hemophilia are some genetic diseases—diseases caused by problems in genes.Today,scientists are looking for ways to cure genetic diseases by changing genes through a process called gene therapy.
