Rachel had her mobile phone with her, so she sent a text message to five friends in the UK     4    (get) their help.

About four hours later, one of her friends, Martha, responded     5     her with a text message. Martha said she had phoned the police in Switzerland and that they had got in touch with the mountain rescue team.

But the weather was so bad     6     the helicopter (直升飞机) couldn’t get to the two climbers. The rescue team sent a message to Rachel,     7    (say): “So sorry Rachel. We tried. Wind is too strong. Have to wait till morning. Take care. Be strong.” Rachel felt     8    (hope) and thought they were going to die as it was freezing, －15 ℃. However, Jason encouraged her, telling her not to give up.

Next morning the storm     9    (pass) and the helicopter arrived to take them off the mountain. After the accident, they cared for each other with greater     10    (devote).

John Henderson, 106, and his wife Charlotte, 105, from Austin, Texas are the oldest living couple on Earth. They have 80 years of     1    （marry）.

The couple, who met each other in 1934 while studying in the University of Texas, married in 1939. When     2    （ask）about their years together, Charlotte said. "We have always cared for each other. It is just one of those things that     3    （natural）comes to us."

Longhorn Village, the senior living community    4     the Hendersons live, helped the couple celebrate their anniversary by     5    （throw）huge party. At the party, the two lovebirds     6    （surprise）by a 1920s car, similar to the one John used to drive to impress Charlotte when they first met.

In late April 2017, a violent storm swept through the southern United States,     1    (destroy) more than $ 1 billion in property and killing 35 people. But it was     2    wonder that a group of birds sensed the oncoming disaster and left long before the first clouds arrived. A year earlier, a science team had tagged golden-winged warblers (莺) with leg trackers     3    ( study) their annual migrations to South America. Two days before the storms     4    (strike), five golden-winged warblers flied away, traveling south to the Florida coast.

It's the first time that the birds which normally migrate with the seasons     5    (observe) to fly away when a big storm hits. The researchers suspect this behavior occurs only when the threat of     6    (injure) outweighs the energy costs of a long trip. But nobody knows     7    the birds guessed the storm's harm and left so soon.     8    ( puzzle) by it, the scientists initially reasoned that changes in weather—atmospheric pressure, temperature or wind speed—signaled the upcoming disaster. Yet when they checked weather records, none of these factors waved     9    (significant) before the storm. Instead, the team thinks that the approaching storms created a disorder of infra sounds, low-frequency sound waves, that birds can hear,     10    humans can't.

A population of the world's most invasive mosquito species was almost completely wiped out by    1    experiment on two islands in the southem Chinese province of Guangdong, according to a study , which     2    (publish) Wednesday

The experiment successfully reduced the female Asian Tiger Mosquito population-the main source of bites and disease transmission-by up to 94%,    3     (reduce) the number of reported human bites by 97%.

One of the Chinese study's    4    (researcher), Xi Zhiyong, a professor at Michigan State University, has been a longtime pioneer in this field of study,    5    is running a mosquito factory in southern China. He    6    (previous) attempted to use sterilized(绝育的) male mosquitoes to mate with unaltered females In the new study,    7     (publish) by the International Journal of Science, Xi and his colleagues attempted to cut mosquito numbers even    8    (far) by limiting both males and females' ability to reproduce.

The results were so successful that they nearly    9     (wipe) out the entire female mosquito population on the two islands.

Mosquitoes pose grave threats to human health beyond just irritating bites. However, there is currently no effective vaccine or treatment     10    most mosquito-transmitted diseases, leaving controlling the insects' populations one of the most effective control methods, according to the International Journal of Science.
