More surprising，perhaps，than the current difficulties of traditional marriage is the fact that marriage itself is alive and thriving (兴盛)．As Skolnick notes，Americans are marrying people—relative to Europeans，more of us marry and we marry at a younger age．Moreover，after a decline in the early 1970s，the rate of marriage in the United States is now increasing．Even the divorce rate needs to be taken in this pro-marriage context: some 80 percent of divorced individuals remarry．Thus，marriage remains，by far，the preferred way of life for the vast majority of people in our society．

What has changed more than marriage is the nuclear family．Twenty-five years ago，the typical American family consisted of a husband，a wife and two or three children．Now，there are many marriages in which couples have decided not to have any children．And there are many marriages where at least some of the children are from the wife’s previous marriage，or the husband’s，or both．Sometimes these children spend all of their time with one parent from the former marriage;sometimes they are shared between the two former spouses．

Thus，one can find the very type of family arrangement．There are marriages without children;marriages with children from only the present marriage;marriages with “full time”children from the present marriage and “part-time” children from former marriages．There are stepfathers，stepmothers，half-brothers，and half-sisters．It is not all the unusual for a child to have four parents and eight grandparents！ There are enormous changes from the traditional nuclear family．But even so，even in the midst of all this，one thing remains constant: most Americans spend most of their adult lives married．

1.By calling Americans marrying people the author means that ______．

A．more of Americans，as compared with Europeans，prefer marriage and they accept it at a younger age

B．Americans expect more out of marriage than Europeans

C．there are more married couples in USA than in Europe

D．Americans are more traditional than Europeans

2.Which of the following can be presented as the picture of today’s American families？

A．A typical American family consists of only a husband and a wife．

B．Many types of family arrangements have become socially acceptable．

C．Americans prefer to have more kids than before．

D．There are no nuclear families any more．

3.Even though great changes have taken place in the structure of American families ______．

A．the functions of marriage remain unchanged

B．most Americans prefer a second marriage

C．the vast majority of Americans still have faith in marriage

D．marriage is still enjoyed by all Americans

Swimming across the English Channel is no easy feat. In addition to the strong ocean currents, swimmers also have to endure extremely cold temperatures. However, don't tell that to Sarah Thomas. The 37-year-oki American recently became the first person ever to swim across it not once, hut four times non-stop!

"I just can't believe I did it/' Thomas told the BBC after the swim. "I'm really just pretty numb. There was a lot of people on the beach to meet me and wish me well, and it was really nice of them, but I feel just mostly stunned."

What makes Thomas's achievement even more remarkable is that just a year ago, in 2018, she was undergoing treatment for breast cancer. She said that fighting the strong currents was hard. But even worse was “dealing with the saltwater... it really hurts your throat your mouth and your tongue”, she said. “I got stung(蛰)in the face by a jellyfish. The water wasn't as cold as I thought it might be, but it was still very cold."

Thomas’s record-breaking journey began just past midnight on Sunday, September 15, 2019, when she dove into the waters off the shore of Dover, England. Though the swim was initially meant to be about 80 miles, strong currents forced the athlete to change course several times, lengthening the total distance by about 50 miles. By the time she appeared from the water at 6:30 a.m. local time on Tuesday, September 17, 2019, she had been in the water for 54 hours and 13 minutes and swum a total of 133 miles! Even more impressive, Thomas achieved the astonishing feat in a regular swimsuit. Her only aids were swim goggles, one cap, a nose clip, and earplugs。.

This is not the first time Thomas has swum across the English Channel. She has done it twice before, in 2012 and 2016. She told filmmaker Jon Washer, who is making a documentary about her swim, “As I was doing 20 mile swims, it occurred to me that I could do more and I wanted to see what that more was." The swimmer, who is being praised “an absolute legend" by the CS&PF, has indeed shown the world what she is capable of However, we have a feeling she is not done yet!

1.By mentioning “Swimming across the English Channel is no easy feat", the writer aims to

A.warn people not to swim across it

B.arouse people' interest in swimming

C.set off Sa rah Thomas's achievements

D.stress the difficulties swimmers have to conquer

2.What does the underlined word “stunned" mean in Paragraph 2?

A.Surprised. B.Satisfied. C.Doubtful. D.Regretful.

3.What troubled Thomas most during swimming?

A.Strong currents. B.Sea water.

C.Jellyfish. D.Water temperature.

4.What does Paragraph 4 mainly focus on?

A.The long distance she covered.

B.The ordinary equipment she possessed.

C.The record-breaking time she stayed in water.

D.The impressive determination she displayed.

5.What can we infer from the last Paragraph?

A.A documentary is being made about her achievements.

B.She has swum across the Channel more than once.

C.She will probably plan to swim the Channel in the future.

D.She is capable of doing everything she wants to achieve.

The most important use of drifting (漂流) bottles is to find ocean currents. When the position and direction of currents are known, ships can use the forward movement of a current or stay away from currents that would carry them off their course. Benjamin Franklin was one of the first to use bottles in the study of currents. He wondered why British mall ships needed a week or two longer than U.S. ships needed in order to cross the Atlantic Ocean. Franklin thought the Gulf Stream (墨西哥湾流) might explain this difference.

Franklin talked with captains of U.S. ships. He found that they knew each turn of the Gulf Stream. They used the current in every possible way. From his talks with the captains.
