3.It is reported that China ______ its first orbiting space station by around 2022.(  )
A.is to completeB.is going to complete
C.will completeD.will have completed

分析 据报道,到2022年左右中国将建成第一个轨道太空站.

解答 答案:D.
by+时间作状语时,主句通常用完成时态.根据时间状语by around 2022可知,时间是截止到一个将来的时间,所以设空处应该用将来完成时(will have completed),故选D.

点评 本题考查时态.时态题关键在于对句意的理解,要根据上下文以及时间状语,找到符合语境的答案.

4.Located in northern Manitoba on the west side of Hudson Bay,Churchill is out in the middle of nowhere.But polar bears like it that way.They spend summers on the tundra (苔原) around Churchill.In the fall,they wait anxiously along the shore of Hudson Bay for the ice to form.Then they go out onto the frozen sea to hunt ringed seals--their favorite food.October and November are the best polar-bear viewing times.From tundra vehicles,visitors to Churchill observe the bears.Some enjoy day trips or stay overnight on large tundra vehicles that have private cabins and eating facilities.Others stay at a wilderness lodge on the bears'migration route to view the vigorous creatures.These lodges can be reached only by air and feature luxury food and living arrangements.
Despite the large number of polar bears that visit Churchill each year,there is growing concern about the animals'future.Because the earth is getting warmer,the ice forms later in the year now and disappears sooner in the spring.As a result,polar bears have less time to hunt for seals.Polar bears can also find smaller animals,bird eggs and berries on land,but this kind of food is not sufficient to support the animals.
Polar bears are also affected by plastic and chemicals that get into the ocean.A research project carried out in northern Europe has found high concentrations of both plastic and chemicals in the tissue of polar bears.These materials and substances can damage the animals'internal organs,especially when the animals are not yet mature.Many people are researching polar bear health.Their goal is to gather the information that is needed to help save these animals.

66.What does this article imply about Churchill?A
A.It's located in a very remote area.

C.It's surrounded by smaller towns.

A.It's starting earlier.
B.It's becoming colder.
C.It's finishing later.
D.It's getting shorter.

A.How they avoid traffic accidents

Health insurance(保险) can be very expensive. Some working people do not make enough money to pay for it. In the US there is a program called Healthy Families. This program offers people health insurance at a low cost.

Families are charged about $7.00 a month for every child, and $10.00 for every adult. It costs much less than any other kind of health insurance. Having health insurance is very important. With this insurance, people can see a doctor when they are sick or hurt.

It would be great if everyone could have health insurance. People are working hard to come up with ways to make this happen. One idea is to make the Healthy Families Program free for some people.
