高二英语单项填空简单题查看答案及解析

In late summer or early fall the large, yellow seed heads of sunflowers will be ripening. If gardeners can keep off the birds and other wildlife trying to eat the seeds, they can have a large harvest. The bright yellow blooms will make a rainbow garden, brightening up any space.

However, planting the sunflower seeds is a skilled job. Plant seeds no deeper than the full length of itself. Smaller sized sunflowers can be spaced a foot apart. Larger varieties will need to be spaced as far apart as three feet. This allows ripe plants enough space for the seed heads to ripen without knocking the ripe seeds off before gardeners have a chance to harvest them.

Most sunflower seeds, especially those with eatable seeds, are large enough to handle without the need for seed sorters. This is why sunflowers make an excellent choice for a children's garden as well. Gardeners will want to mix plenty of soil fertilizers into the ground as sunflowers tend to be heavy feeders.

Sunflowers can be slow starters and the tiny new plants don't seem to grow very rapidly. Gardeners should protect the new plants as they begin to grow. Once they get going, sunflowers are able to out-grow many weeds, making them easier to grow in the home vegetable garden than many other plants.

Most pests and diseases are not a bother to the sunflower, however, more than one gardener has said that their lovely looking plants were ravaged overnight by hungry squirrels, mice or birds. To preserve their harvest, gardeners can cover the ripening seed head with stockings or net cloth to help keep the destroyers off the seeds.

Planting sunflower seeds is easy and can help even the smallest gardener feel successful in their gardening attempts.

1.What is the passage mainly about?

A. How to plant sunflowers.　　 B. Different kinds of sunflowers.

C. Ways to preserve sunflowers.　　 D. Tips on making your garden bright.

2.Why should enough space be left between sunflowers?

A. To prevent birds from eating sunflower seeds.

B. To offer the sunflowers enough sunlight.

C. To protect the ripe seed heads before harvest.

D. To help the sunflowers grow stronger.

3.Why do children love to grow sunflowers in their garden?

A. They want to decorate their garden with sunflowers.

B. The seeds are easy to plant and unnecessary to sort.

C. Sunflowers don’t need too much soil fertilizer.

D. Tiny new sunflowers can grow very fast

4.Which of the following can replace the underlined word “ravaged” in Paragraph 5?

A. Destroyed.　　 B. Covered.

C. Surrounded.　　 D. Removed.

高二英语单项填空中等难度题查看答案及解析

Wild mangoes come from the foothills of the Himalayas. They are by far the most important fruit in India, and have been cultivated there for four thousand years. The arrival of the mango tree in other parts of the world was probably due to the Portuguese who carried mangoes via Goa to Africa, from where they eventually reached the New World. Mango trees are now so well established in many tropical countries that it might appear that they have always been there.

Like many tropical trees, the mango tree is multi-purpose product. Its wood is used in boat building, and its leaves can be fed to cattle. Most of the mango crop is consumed in the areas where it is grown, but in recent years mangoes have gained in popularity across the world as people in mild climate become increasingly eager to enjoy the delight of the fresh fruit.

The global market for mangoes is very profitable, and mango producers are keen to make use of the fruit's growing popularity. Modern shoppers not only appreciate the fruit's high nutritional value(the mango is a good source of vitamin A and C, protein and fibre), but also expect it to look and taste perfect. Therefore producers now select only the best quality seedlings which have the most chance of developing into good quality fruit.

Mangoes are high in fiber, thus making them very good for the heart. The high fiber content is also helps easing constipation. They have high pectin(果胶) and vitamin C content that reduces the blood cholesterol levels and serves as an immune booster. This fruit is rich in anti-oxidants, vitamins, minerals and contain an enzyme(酶) that has stomach soothing properties. These enzymes act as a digestive aid and digestive proteins.

Although the mango tree has spread from its native Himalayan foothills to the tropics, delivering the fresh fruit to the world's supermarkets presents a challenge, as it does not travel well. Producers transport the fruit by speedy but costly air freight (货运)for minimum delay rather than risk the cheaper but slower road or shipping routes which, can result in damage to the fruit.

Mangoes are usually in storage for some time after their arrival at their destination. The fruit must be kept cold, or the sweet, juicy flesh will soon become over ripe and the mangoes will be unfit for sale. Fortunately, extremely effective refrigeration is now available and this is the best way of preventing the fruit from going bad before it reaches the supermarket shelves.

1.What does the underlined word “there” in Para. 1 refer to?

A. In Africa　　 B. In India

C. In the New Worde　　 D. In many tropical countries.

2.According to Para. 2, a recent change in the mango market is that_______.

A. farmers in mild climates produce more mangoes

B. mangoes become more popular around the world

C. the mango tree is becoming a multi-purpose product

D. the mango crop is consumed in tropical countries

3.Which of the follow can be the subtitle(副标题) for Para.4?

A. Mangoes are rich in anti-oxidants.

B. Mangoes are very good for the heart.

C. Nutritional information on mangoes.

D. Eating mangoes can cure people of some disease.

4.From Para. 5 we know the challenge mango producers face is________.

A. how to cultivate them　　 B. how to transport them

C. how to sell them　　 D. how to store them

高二英语阅读理解中等难度题查看答案及解析

Cities in Europe and around the world may be growing “bike trees” in the near future. Invented by Japan’s JFE Engineering Corp, the invention proved useful in the busiest parts of this nation’s crowded cities.

Local governments of Japan have struggled for ways to encourage people to park their bikes considerably, particularly close to big stations, but that may block some roads and entrances to homes and businesses. “Our cities do not have a lot of space for any kind of parking, including bicycles.” said Mitsuharu Oshima, a spokesman for JFE Engineering. The bike tree comes in two types: one in a tower that is above ground and on the contrary, the other in an underground structure.

A cyclist registers with the operator of the equipment, pays a monthly fee and pushes the wheels of his bicycle into restraints(管理处) at the base of the bike tree. Each bicycle is fitted with an electronic card with the owner’s details. A mechanical arm then pulls the bike into the base of the tower and moves it to a free location inside. To collect the bike later, the cyclist puts his card through a reader and his bike is automatically returned to him in seconds. “The science of the equipment has been difficult —— even though they may look quite simple —— because bikes come in many different shapes and sizes.” said Oshima.

As well as clearing away the road, bicycles cannot be stolen from a bike tree. There are presently versions at seven sites in Japan and two others are under construction, while work is under way on an even larger version —— with room for 9400 bicycles —— in Thailand. And Oshima believes that the idea could catch on in Europe, particularly in countries such as France, Holland and Denmark , where cycling is so popular.

1. Cities build this kind of “bike trees” so that they can _______.

A. ask more people to ride bikes      B. provide more jobs for people

C. make more money than before     D. save more room for people

2.Which is the right order of the following things when you use the bike tree?

① the wheels of the bicycle are put into restraints at the base .

② the card is read and the bike is automatically returned .

③ an electronic card with the owner’s details is given

④ the bike is pulled and moved to a free location inside .

A. ③②①④     B. ③①④②       C. ②①④③        D. ②④③①

3. What made it difficult to design “bike trees”?

A. The location of “bike trees”.         B. The method of finding enough bikes.

C. The differences of the bikes.         D. The importance of traffic safety

4. From the passage, we can know that _______.

A. countries with many cyclists in Europe will like the idea of “bike trees”

B. there are seven “bike trees” used for holding bikes in Japan

C. local government of Japan encourage people to ride bikes

D. cyclists can use “bike trees” for free in Japan.
